Purchasing a new CPU for my laptop

by Tech05 / August 21, 2005 1:26 AM PDT

Hey,

I was wondering if there is a way to upgrade my CPU from a celeron to a pentium M or any other processor. I have a gateway m320, I opened the slot on the bottom of the laptop and i could clearly see the CPU chip. All i had to do was remove the heat sink and pop out the old CPU and stick in the new one. But i want to make sure that this is OK to do. I have a windoes XP home with 512mb and 40GB hard drive.

Reply with any thoughts.

thanks,

Don't bet on it

Laptops are typically a "What you see is what you get" sort of proposition. Sometimes you can add a little additional RAM, in a few rare cases, you've got a mini-PCI video card that can be swapped out, and there's always the HDD, but that's about it. Things like the CPU are soldered directly to the motherboard, and can't easily be removed. If you're handy with a soldering iron, maybe, but then you have to contend with the fact that the BIOS may not support the CPU you replace it with.

It's best not to even try, unless you don't care if it ends up being little more than a door stop or paperweight. Because if you try what you're thinking, that's a very distinct possibility. Best to just let it be a lesson for your NEXT laptop. Don't skimp. Save your money until you can buy a nice top end model.

I have never replaced a laptop CPU before, but here is what
by lath / August 21, 2005 2:58 AM PDT

i'm thinking: in some cases, it is possible to upgrade a laptop CPU (for example, from celeron to pentium). some of critical conditions must be matched such as voltage, front side bus, socket type, etc. (Pentium M is a chip that requires a much lower feeding voltage than normal chip)

The best pratical is to look on what kind of CPU that the motherboard can support (for example: maximum speed/multiplier setting).

When you remove the heat sink, you can see information about your current CPU printed on its side. New CPU should have same range. Cache size may be different, new CPU may have multiple front side bus range.

In case that the laptop has a mounted CPU on board, my suggestion is not to try it. You can easily damage it when trying to remove it. There is a risk that you have to replace entire motherboard.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
