Best CPU & Motherboard upgrade for Compaq Presario CQ57-215SI

[Arno89]

I've got an HP Compaq Presario CQ57-215SI.

CPU: Intel Celeron 925@2.3GHz
Motherboard: HP 3676 v29.2B (serial: [Personal Information Removed])

I can upgrade to 8GB RAM and a 12 cell battery, but I'd like to find out what the best CPU/Motherboard combo is that the laptop can take?  Or even just the best CPU my current motherboard can take?

@Arno89 Welcome to HP Community!

I understand that you would like to upgrade the processor and motherboard.

(HP does not recommend upgrades as the device is equipped with parts that perform at its optimal performance and also, the upgradeable parts listed in HP articles are purely for your ease, though the decision to upgrade will be at your own discretion)

I have checked the manual ( page number 18)

Your laptop support following processor and motherboard.
