Laptop CPU upgrade Query

[Mattstarky]

Hi, i have bought a COMPAQ v5110eu recently, it currently has a Mobile Sempron 3300+ in it, however it has a TDP of 65w and it gets quite hot and battery life runs low quite fast, i have done some research and concluded that a Mobile Sempron 3100+ (25w) version would increse battery life and reduce heat. However, im not too sure if my laptop supports this pocessor.
or for that metter how to open up my v5000. I have found a panel above my keyboard. It does lift out, and i presume that i can remove the keyboard and then swap out the processor. I have searched the web to see if anyone else has removed the keyboard.
Wonder if anyone could offer any suggestion.
Cheers
Matt

you might be able to find a teardown guide on the internet if it is a higher end model but otherwise you may have to just explore

Only way to find out is to strip it down and make sure the CPU is socketed... As long as it is and is not surface mounted then I don't see a problem... Is the current CPU covered by an IHS ala the the normal desktop chips? Or has it got a tiny little core without a metal covering?

AFAIK the chips packaging is identical and thus the only real world difference apart from different ID strings possibly is the fact it will happily run at lower voltages...

Most frustrating, i have removed all the screws on the back, there are none other visable, even under the hard drive and ram cage. and still the back wont come off. it levers away allmost as if one screw is still holding it together. but i just cant get to it.
normally you would removed the keyboard to replace a laptop CPU, but i dont seem to be able to do that *sigh*

There is probably a screw hidden under either a sticker or a panel e.g. a panel covering the RAM slot(s).

Post a picture of the bottom of the laptop if your really stuck... I have looked at various laptops in the past so am fairly familiar with how to strip them down

Took my Thinkpad T41 apart last week to apply some Artic Silver to the heatsink, solved the overheat shutdown problem.

All I had to do was remove the keyboard and palmrest. Luckily IBM have a hardware service manual for every model detailing every screw and panel which needs to be removed to get to any part.

To remove the keybaord I had to take out about 5 screws from the underneath and then push it forward (towards the LCD) to clip it away from under the palm rest. Try moving the keyboard around once you are sure you have removed all the screws right screws.
