Processor also known as CPU

Laptop processor CPU

A processor also known as CPU (Central Processing Unit) is the brain of a laptop computer. The processor is one of the main components in a laptop. Laptop processors are made mainly by Intel and AMD.

The processor connects directly to the system board via a processor socket aka CPU socket as it shown on the picture below.

QUESTIONS AND ANSWERS.

Question: Can I overclock the CPU in my laptop?
Answer: No, you cannot. In most laptops the BIOS doesn’t give you this option.

Question: Can I upgrade the CPU in my laptop?
Answer: Unfortunately, laptop manufacturer’s do not provide this information to general public. Yes, it’s possible on some laptops. You’ll have to find a new CPU which fits the same socket and try it.

Question: Are CPU failures very common?
Answer: No, they are not. CPUs fail rarely. If your laptop stopped booting, the CPU will be the last component to blame. Check the memory and motherboard first.

    hardik,

    i have compaq presario c795tu ,in my laptop lan is working but not bluetooth ,i want to know can i know that my laptop has bluetooth hardware or not without touching any hardware

    Take a look in the device manager. If you have Bluetooth module in the laptop, it will appear in the device manager.
    If you don’t have it, you can buy a small USB Bluetooth plug. It’s small and you don’t have to disassemble the laptop.

  11. Evi says:

    Yeah, I’ve figured that out since. Thanks for answering though. I chose an i5 Intel. AMD is nice when you want a budget computer :P.

  12. Repair Man says:

    Evi,

    I know, I’m asking questions about everything :P . I have an AMD CPU. I’m going to build my own computer, would you suggest AMD or Intel? Intel is more credible to me, but I don’t know much about AMD.

    I would go with Intel.

    I know, I’m asking questions about everything :P. I have an AMD CPU. I’m going to build my own computer, would you suggest AMD or Intel? Intel is more credible to me, but I don’t know much about AMD. I suppose it would depend on what the computer is for?

    Duaine,

    Intel 2.20GHz P4

    I checked parts listed for Toshiba Satellite A15 laptop and along with Celeron 2.4GHz they mention Pentium 4 2.2GHz for same motherboard.
    I think you can use this one. This is my guess.

  15. Duaine says:

    I have a Toshiba Satellite A15-S129 that has a 2.4 GHz mobile celeron processor and it is easy to access it to replace it.
    Is there a better or faster processor I could use, such as a Pentium 4?

  16. princewill says:

    my laptop doesn’t beep and no display on the lcd. could this be a processor problem, or is the mother board fried?

  17. Repair Man says:

    Steve,

    would that 4gb of additional ram be worth it? considering laptops have standard of 2 slots, and so far 2 2gb sticks are in, Would replacing them with 2 4gb sticks be worth it or not? and I’v checked with Everest software and it says that they can handle 8 gigs.

    Yes, if the laptop can handle 8GB. I would go for it.
    There shouldn’t be any problem with the OS because you are running a 64-bit OS.
