Presario CQ57 CPU Upgrade to i7 2360qm - Is it possible?

[User10005]

I have old laptop Compaq Presario CQ57 with 6GB RAM and Celeron B800 1.5ghz CPU. My CPU is removable, so I can change it. Please answer me can I upgrade this laptop with i7 2630QM CPU and if I can't, what is the best CPU for upgrade? Thanks

Your chipset supports it but there is no guarantee that you wont need modified bios with added microcode for cpu: http://www.cpu-upgrade.com/mb-Intel_(chipsets)/HM65_Express.html

This is the cpu you say you want to buy : http://www.cpu-upgrade.com/CPUs/Intel/Core_i7_Mobile/i7-2630QM.html
Look the list below for chipset compatible processors, b800 has tdp 35w and i7-2630qm has 45w meaning you could overheat very easily.
I checked your laptop model and didnt find any what even sold with an i7 meaning its a risk you end up 90c when booting it up

However a safer step with guaranteed non overheating issue would be to get i5-2450m, you jump from 2 core 2 thread to 2 core 4 thread and boost frequency at the same time making it way faster overall.
Also your motherboard by big change supports the cpu microcode ( flash latest bios obviously before you test ) below is the manual stating i5-2450m is upgradable

dont worry you will triple the speed even going from b800 to i5 - 2450m
