All main laptop and notebook parts explained

On this website you will find information about all main parts inside a typical laptop or notebook computer.  You can identify parts by the description or image below. In order to get more information about a particular part, you can follow the link in the description or simply click on the image.

SYSTEM BOARD aka MOTHERBOARD

The system board is the main logic board in any laptop. All internal components are connected to the system board. This is one of the most expensive parts in a laptop.

MEMORY aka RAM


More memory you have installed – better the performance of the laptop.
Learn about different types of memory, compatibility issues and how you can replace or upgrade memory yourself. The memory is a user replaceable part.

HARD DRIVE

The hard drive is the main storage of information in a laptop. All system files, personal files are stored inside the hard drive. Find the difference between SATA and IDE hard drives. Faster hard drive you have installed – faster data access you get. You can upgrade the hard drive yourself.

PROCESSOR aka CPU

The processor is the brain of your laptop. Faster CPU means faster data processing.

KEYBOARD

The keyboard is the main input device. Find out how the keyboard is connected to the motherboard and how it can be removed or replaced.

CD/DVD OPTICAL DRIVE

The CD/DVD drive allows you to read/write data from/to a CD or DVD disc. Lear about the difference between drives with regular and SATA connectors.

COOLING FAN

The cooling fan is a part of the cooling module in a laptop. The fan helps to cool down the processor when the laptop is turned on.

VIDEO CARD aka GRAPHICS CARD

In most modern laptops the video card is integrated into the system board. If the video card fails you have to replace the whole motherboard.
In some laptops the video card is a discrete module and can be removed or replaced separately from the motherboard.

AUDIO BOARD aka SOUND BOARD

In most laptops the audio board is a part of the motherboard. If that’s the case, all audio board input/output components such as volume control, microphone jack and headphone jack are soldered directory to the motherboard.

WIRELESS NETWORK CARD

The internal wireless card helps you to connect to the Internet without running a cable. Learn about different types of internal wireless cards and how they are connected to the motherboard.

CMOS BATTERY aka RTC BATTERY

The CMOS battery provides power to the CMOS chip when the laptop is turned off or disconnected form the wall outlet.

LCD SCREEN

The LCD screen is one of the most expensive parts in a laptop computer. The LCD screen mounts inside the display panel.
If you accidentally cracked the screen, it has to be replaced. You cannot repair  a cracked screen.

SCREEN INVERTER BOARD aka FL INVERTER

The inverter board is a power supply for the backlight lamp inside the LCD screen. When inverter fails, the LCD screen goes very very dark and you barely can see any image on the screen. In most laptops the inverter board is mounted inside the display panel below the LCD screen.

SCREEN BACKLIGHT LAMP aka CCFL TUBE

The backlight lamp is the main source of light in the LCD screen. The backlight lamp is mouted inside the screen. When the backlight lamp fails, you have to replace the whole LCD screen. It’s possible to replace just the lamp inside the screen but it’s very hard and has to be performed by an experienced technician.

SCREEN CABLE aka VIDEO CABLE

The video cable connectes the Laptop screen to motherboard. The video cable carries data signal for the LCD screen and power for the ivnerter board.

WEB CAMERA

Many modern laptops come with a web camera built into the display panel. The web camera is not a part of the LCD screen. The web camers is located on a separate board and can be replaced separately from the LCD.

DISPLAY HINGES aka SCREEN HINGES

The dispaly hinges connect two main parts of any laptop – the display panel and base assembly.

AC/DC POWER ADAPTER

The AC/DC power adapter converts high voltage AC power from the mains to low voltage DC power required by the laptop.

MAIN BATTERY

The battery is a secondary source of power for a laptop. The battery gets charged while the laptop is plugged into the mains and keeps the laptop running when it’s unplugged from the mains.

    hi,
    I have Toshiba Satellite 1905 S301 laptop, when the laptop is switched on the screen remains completely dark. I connected it to an external moniter, the moniter displays a message “NO SIGNAL”. I can hear the hard disk working without any display. I would appreciate your suggestions for this problem.
    Thanks

    Try to switch video from the internal to external mode using Fn+F5. Press and hold done the Fn key and at the same time press on F5. Can you?
    Are you sure that there is no image on the screen at all? Take a closer look. Maybe the image is there but it’s very dim?

    Yes, you can install 4GB RAM into this laptop. It will take up to 2GB module in each slot.
    You should be able to install a 250GB PATA drive without any problem.
    No, your laptop will not support SATA hard drive, it has a different connector.

    Are you trying to switch video from the laptop screen to the external monitor? Sometimes you have to press some keys on the keyboard in order to switch internal video output to external. For example on Toshiba laptops you have to use Fn key and F5, on IBM ThinkPad Fn key and F7.

    First nice to meet you.
    I have tree laptop with a diferent problem.
    1. Asus M50 only turns on when I putt off rams but no image. If i put back turn on and them turns off automatic.
    2. Asus G70 when I turn on the image it’s very clear only see if you put a external monitor.
    3. HP ZD7000 I turns on and atomatic turns off no fan moving nothing. I change cpu and memory but the same.

    If you can help, yo lo aprecio gracias.

  11. Rebecca says:

    so there is this plastic piece that fell out of my computer when I dropped it the other day.

    I have an HP dv6000
    the piece is located on the right side of the computer where all the usb ports are. There is a symbol above where the piece goes that looks like a square with wind behind it. The same symbol is on the piece. No idea what it is. It is really bugging me.

    I thought it was the remote for my computer but it is hard plastic shaped like an L.

    What is this?

  12. Repair Man says:

    Hector,

    Asus M50 only turns on when I putt off rams but no image. If i put back turn on and them turns off automatic.

    If it happens with both memory modules, most likely there is a problem with the motherboard.

    Asus G70 when I turn on the image it’s very clear only see if you put a external monitor.

    Do you see any light on the laptop screen? Take a closer look, maybe the image is on thescreen but it’s very dim? Let me know.

    HP ZD7000 I turns on and atomatic turns off no fan moving nothing. I change cpu and memory but the same.

    If you changed the CPU and RAMs, the problem must be related to the motherboard. I don’t know what else can cause that.

  13. Hector says:

    The asus G70 yes I see very dim if I connect a external monitor works great, Did you think if the lamp or the converter. The laptop only I use ten times it’s new.

  14. Ron, asks. says:

    I have a everex av250e . when you power up sometimes dark screen, but after you get screen,you will hear a arc and computer shuts off. you power back up and have to start in safe mode and this is all the time once you get it on. can you help me?

  15. Repair Man says:

    Hector,

    The asus G70 yes I see very dim if I connect a external monitor works great, Did you think if the lamp or the converter.

    You will not know which one is causing the problem until you test the laptop with another known good backlight lamp or inverter board. Could be either one. Both have very similar failure symptoms.
    Inverter failures are more common than backlight failures.

    The laptop only I use ten times it’s new.

    Can you take the laptop back to the store and exchange for a new one?

  16. Repair Man says:

    Ron,

    I have a everex av250e . when you power up sometimes dark screen, but after you get screen,you will hear a arc and computer shuts off. you power back up and have to start in safe mode and this is all the time once you get it on.

    Is it happening when you run the laptop on AC power? What if you start from the battery, will it fail the same way?

  17. Hector Millan says:

    No, I cannot return because I don’t have warranty on my country yet, I live in Puerto Rico, I need to send it to USA and them they send it back to a person hoos live there

    Hi I have a ibm thinkpad t 41 that upon start up goes to bios for a second then the screen turns white. thanks

  19. Repair Man says:

    Lester Ceruti,

    Hi I have a ibm thinkpad t 41 that upon start up goes to bios for a second then the screen turns white.

    1. Could be poor connection between the video cable and LCD screen. Try reconnecting the cable.
    2. Could be bad LCD screen or motherboard problem. You cannot tell which one is bad until you test the laptop with another working LCD.
    Try video output on the external monitor. Does it work properly. If video on the external screen works fine for a few seconds but after that goes bad, probably it’s related to the motherboard.

  20. Repair Man says:

    Hecktor Millan,

    The asus G70 yes I see very dim if I connect a external monitor works great, Did you think if the lamp or the converter.

    Here’s something I forgot to ask. You said the screen is very dim but how dim it is?
    Does it look like the backlight is not working at all, or the backlight works but it’s not bright enough?
    Did you check LCD brightness settings?
    In some laptops you can adjust screen brightness in the BIOS setup menu, not sure about your laptop.

    I don’t know what’s the problem with my laptop, when i install an online game it’s always lag. and too slow to read and it’s always reading.
    I don’t know much about external or internal problem on laptop but why is it like this.

  22. Repair Man says:

    WannaKnow,

    I don’t know what’s the problem with my laptop, when i install an online game it’s always lag. and too slow to read and it’s always reading.

    Most laptops are not designed for running games. Do you have a good discrete video card in the laptop? Do you have enough memory? Do you have a fast 7200RPM hard drive?

  23. WannaKnow says:

    I dont know how to find out if the video card of this laptop is good and th memory of this laptop say’s 1024MB, Hard Drive is 160GB CPU Pent. T3200 OS Free DOS

    Hi, Saludos;

    Have you checked the BIOS settings? Maybe there are some settings for the laptop screen in the BIOS?
    Did you try switching video from internal to external mode using Fn+F8 keys?

    Try reconnecting video cable on the motherboard. Maybe the cable is not making good contact with the motherboard.

    If nothing helps, it’s either bad video cable or there is a problem with the motherboard. I assume your new LCD and inverter are good.

  26. Jumme says:

    Hello, nice site, seems you are quite experienced.

    Thing is, I just got an old Acer Travelmate 240.

    Downgrated CPU from
    “Intel Celeron 2.6GHz SL6VV TDP:62.3W” to
    “Intel Pentium 4-M (mobile) TDP:20/32W 2Ghz” running @ 1200Mhz (this is actually due to BIOS not reading the CPU right).

    Question: I want to make the very whining cooling fan run less noisy (slower). As I allready underclocked the CPU, theres allmost no heat, but still the CPU fan kicks in every 2 minute.
    Could I install some kind of resistor on the cable of the fan, to make it run less noisy?
    Or change the fan completely? Did you try this?

    Its a small 3-wire connector, 5V, 0.4A.

    Thanks in advance.

    Hi, I have a minor problem with my Asus N81V laptop. Whenever the laptop is asleep and I unplug my USB mouse (or any other usb device), the computer automatically boots up as if I had hit the power button. Ideally the laptop would stay asleep after removing the usb device. Have you heard of this problem? Is there anything I can do? Any help is greatly appreciated.

    Thanks,
    David

    I’ve never seen a problem like that and not sure what’s going on.
    Check the BIOS setup menu, maybe you can find some laptop wake-up settings in there. Load default BIOS settings and safe them. Reboot the laptop and see if the problem is fixed.
    Also, find out if there is a newer version of BIOS available for updates. Maybe it’s a known problem and Asus fixed it with the BIOS update.

    I wouldn’t mess with the components on the motherboard. You can fry it.
    Have you tried replacing thermal grease on the CPU? Maybe thermal grease dried out and the fan kicks in because the CPU is getting hot.

    I am having a problem with my Compaq v2000.
    I was using the laptop via battery and the comp went into hibernation due to “low battery”. I plugged in the comp to recharge and cannot restart system. The Compaq intro screen comes up for approx 1/2 a second, 2 beeps are heard, then in the upper left corner a message appears:
    Press to resume, press for setup
    I tried pressing both on different restarts and nothing happens.
    Any ideas what the probelm could be and how to fix it?
    Much appreciated.

    Here’s what you can try.
    Turn off the laptop, unplug the AC adapter. Remove the battery. Wait for a couple of minutes, plug in the AC adapter and try turning it on again.

  33. clb7210 says:

    Same symptoms occur after trying to restart with your suggestion:
    Compaq intro screen up for a split second, followed by 2 beeps then message in upper left corner “press f1 to resume, press f2 for setup. No reaction from computer when pressing each on seperate restarts.

    Not sure what’s going on. It looks like the laptop is stuck in hibernation mode.
    You can try removing the battery and keep the laptop off (without battery) overnight.
    Also, removing the RTC (CMOS) battery might help too but it’s not easy because the RTC battery is buried inside the laptop. Just in case, here is the official service manual for Compaq Presario V2000 Notebook PC. It’s a pdf file and might take some time to download. The RTC battery removal instruction are on the page 155 but before you can do that you’ll have to go through all preparation steps.

  35. clb7210 says:

    Will try your suggestion.
    Thanks!

  36. clb7210 says:

    Tried your most recent suggestion. Laptop worked for approx 5 min upon restart after removing laptop’s rechargable battery and cmos battery for a few days. While in a momentary working mode I was able to close open programs, then comp froze on screen I was working on. I crossed my fingers on a successful restart-sadly it did not restart. Am currently awaiting delivery of a new cmos battery of same make/model that came with laptop.

  42. Luiz Rakkan says:

    Hello, may you can help me to figure out what is happening to my laptop battery. Before you lose interest in this message, I hope you read a bit more about my issue. Here is the thing: when I turn off my laptop (trademark DATEN, AMD 64bits dual core athlon x2, 2GB RAM, etc.) and turn it on after, say, some four or five hours, my battery is only 90% to 95% charged. So, I make sure that when I shut it down (not stand by) the battery is 100% full charge. So, to make sure that it isn’t a battery issue/problem, I remove the battery and after some hours (and a week in the vacation) I put it back and… 100% charged! The question is: is any part/piece of a laptop that can be running even when I turn the laptop off? It’s like some part, say, the wireless card still sucking my battery life or another part, I don’t know where more to go to solve it. I’m a coder/programmer and I never saw this behaviour before. If you wish to help me out, I can get more information from my Linux or Win32 OS to send it to you. What I’m sure is that the battery is ok and my Ubuntu says that the battery is ok, all cells ok, and it charge full! Hope my english was enough to you to understand me. Thank you in advance.

    Hello Repair Man,

    What do you mean the screen is wavey? Please provide more detailed description.

  48. ScottCha says:

    The screen is broken up horizontally with lines running through it. It sort of jumps around. I can see the Windows XP spalsh screen but it is all broken up.

    If this isn’t descriptive enough I can try to take a picture and send it to you.

    In the previous message you said the screen goes dark, but in this message it sounds like you can see the screen.

    The laptop works with the external monitor, so I assume the motherboard/video card work properly.
    It’s possible that you have:
    1. Bad connection between the video cable and motherboard or LCD screen. Try reconnecting the video cable first. Make sure that connectors on the video cable are plugged correctly. I fixed one laptop with blank/black screen by reseating the video cable on the motherboard last night.
    2. Could be bad video cable. Try replacing the cable.
    3. Could be LCD screen failure.

    The notebook installing Windows updates, that’s why it says do not turn off or unplug. You’ll see this message in the future again.
    Maybe it’s installing a service pack which might take a long time, but to be honest, 4 hours sounds too much.
    Give it more time. If the installation process looks stuck, all you can do is hard power down the notebook. Push on the power button for about 5-10 seconds. The notebook will power off. Most likely on the next restart you’ll get an error message. Select “Start Windows normally” (or something like that).

    This problem could be related to the memory failure. Do you have two memory modules installed in the laptop? Try removing them one by one. Test the laptop with only one memory module installed. It’s very unlikely that both modules failed at the same time and the laptop might start properly when the bad module is removed.

    Make sure the hard drive is connected properly. All pins on the hard drive has to be lined up with wholes on the motherboard connector.
    Is the hard drive is not aligned correctly, only one row of pins gets connected to the motherboard and of course, it’s not working properly. I think that could be your problem.

    When I press the power botton, the lights on the laptop turn on (all of them) but the machine won’t boot up. Nothing comes up in the Screen.

    However this doesn’t happen all of the times I do this. Sometimes it does boot up without a problem.

    What could it be?

    Thanks in Advance.

    It’s possible that one of the memory modules is going bad or not making good connection with the motherboard.
    1. Try reseating memory modules.
    2. Try removing memory modules one by one and test the laptop with each one separately.

    Hi
    Have a problem with a Toshiba A70 lid switch…(Broken)…Is it possible to do away with this switch all together and remove it from the motherboard..(Its a smd)..
    Can’t really tell how it works as all the insides are broken/missing…..?????
    I think it’s a DPDT switch and when the lid closes it makes contact…So the screen will be turned off when the lid is closed.
    Is this correct or does it have some other function…???

    Cheers

    hi,
    I’m in trouble with a situation with an HP Pavilion DV1597EA.
    I wonder if anyone has or knows a site where you can buy a motherboard for the HP DV1597EA, send me a email.
    Thanks in advance.

    The best way to find a replacement motherboard is searching by the HP part number (SPS number).
    In most cases, you’ll find the part number on a sticker glued in the memory compartment (under memory modules).
    The part number will look something like that: 367800-001
    You’ll have a different one but the format should be the same: XXXXXX-001
    Find the part number and google it or search on eBay.

    1. The lid close switch is stuck inside the case and the laptop “thinks” that the display is closed. When the display is closed the backlight is off. Try tapping on the lid close switch.
    2. The video cable is not connected properly. Try reconnecting the cable on all ends.
    3. The video cable is defective. Possible but not likely.
    4. Motherboard failure.
    5. Your new inverter or LCD screen is defective.

    HP laptop DV9723ca w/Vista Home bought 27 March 08.

    1)July/August 09, External monitor goes black but laptop display fine; reinstall video drivers to no avail. Clean install of Win 7; everything normal including external monitor.

    2)October 09, DVD ROM/writer w/ lightscribe not detected. It tries to work, but nothing is being read. Purchase external USB DVD writer which is used as needed, otherwise not connected and everything is good.

    3)January 10, video problems begin again with external monitor; desist using said monitor; laptop display is fine.

    4)February 10, according to Device Manager, the following devices can’t be found: Web Camera, 5-in-1 Card Reader; Conexant Audio. Also, USB device shows as “Unknown” despite no USB devices connected. Attempts at re-install of OS and/or drivers produce no changes to Device Manager faults.

    Sorry for long message, I tried to be concise as possible and yet accurately portray events. If I were to hazard a guess, I’d say main board; however, a visual inspection of it showed nothing outwardly obvious.

    I own a hp pavillion zv5000.It has developed a problem with the charging. If it it plugged intp the mains whilst the computer is operating, it will not charge. The charge indicator light extinguishes. Only when switched off will the charging commence, and even then, the light goes on and off intermittently. I’ve checked the output from the charger, and it is slightly above 20 volts DC. It is awkward, as I use the laptop in a situation where I need to have it operating almost constantly, as it controlling guiding and imaging processes.

    I think there could be a problem with the power jack. The power jack soldered to the motherboard and the battery will not charge because the “+” pin on the jack not making good contact with the motherboard.
    It’s necessary to disassemble the laptop, remove the motherboard and take a closer look at the jack. If the jack is loose, it has to be resoldered.

    Do you get any light when you plug the AC adapter?
    In not, maybe you have a failed AC adapter. Can you test your adapt with a voltmeter?

  86. Michael S Daniel says:

    Yes…I tried that. There is power from the AC adapter but it is the same when I use the battery which is fully charged also.

  87. Laura Francis says:

    Michael,

    Check to see if the battery is the problem. Try taking the battery out and then booting the system using only the AC power. This has happened to several of my systems I manage and it was caused by a problem in the battery, even when the battery is showing a charge. We have battery charge indicators on the Dell battery themselves. When you remove the battery and use the AC power, it should come on.

    If its not the battery, then you are probably looking at a hardware issue (motherboard, hard drive)

    I have also overclocked my videocard. And now 3DMark06 shows 9850 points. And everything works stable.
    The only thing is to do, is to by a faster HDD with 7200 speed, and overclock memory or even CPU. In that case this is going to be a “comet”)))

    If the problem appears right on startup and the Acer logo not centered, most likely it’s hardware related.
    Could be bad LCD screen or motherboard related failure. Cannot tell without testing the laptop with a good known screen.
    If you have to guess, try replacing the screen.

    On the other hand, if the Acer logo displays properly but after that the image shifted to the left side, this could be software related problem. Make sure you are using the correct video driver.

    Visit the laptop manufacture website and try downloading the touch pad drivers and software. Usually you can change touch pad sensitivity through that software.
    If there is no software available, try changing touch pad settings in the control panel (check settings for the mouse).

    Not sure what’s causing that but I had exactly the same problem with one of my Sony laptop two or three times.
    The laptop shut down without any reason but after I unplug the AC adapter and reconnected the battery it started properly.

    Also, this could be related to CPU overheating. If CPU overheats, the laptop will not turn on until the CPU cools down. Make sure the heatsink is clean. If it has much dust inside, clean up the heatsink with compressed air.

    It’s hard to tell what’s going on without looking at the laptop. Could be memory failure.
    Do you have two memory modules installed? Test the laptop with each memory module separately.
    The laptop might start properly when the bad memory module removed.

    Do you mean the scree will not attach to the back cover anymore? Apparently you have damaged the screw anchor which is embedded into the back cover. When it happens, you’ll have to replace the back cover.

    Hi Repair Man,

    I am so pleased to have found your website; it has taught me a lot and given me confidence to tackle my problem.

    Laptop: HP 17″ G70 212EM

    Initial Problem: Screen randomly turning jittery white, perhaps from vibration. This could be corrected however by moving the screen to and fro on the hinges.

    By new found confidence I have removed the screen and keyboard surrounds to see if anything obvious is evident. On inspection I see the inverter has moved out of its seating and the connector arrangement on the left of the inverter has broken up into pieces. I have now purchased a new compatable inverter and screen cable and fitted them into the laptop. I have checked all the other fiddly connectors for fit including the keyboard and on/off and wireless button connection.

    Result after battery and mains connection: Zilch ! No sign of life at all.

    Questions:

    1/ Is it physically possible for the connectors to be fitted up-side-down?

    2/ There is a magnet attached to the back of the keyboard surround fixed with tape directly above the inverter. What purpose does it serve and is its location critical, please?

    3/ Sir, can you kindly give any suggestions that might immediately spring to mind or offer me an analytical procedure to follow so that I can get my dear wife back on line without spending £160 with the ‘Professional Fixer’ down the road.

    Best regards and in grateful anticipation,

    Keith
