I have a Satellite NB10-A-104 with a Celeron CPU N2810 on a Socket FCBGA1170.
In order to obtain better performances I replaced Windows 8 by Ubuntu 16.04 LTS 64 bits and upgrade to 4 Go.

Its clearly better.
But I was wandering if I could upgrade the CPU to a faster one? I look forward to your recommendations.

Thanking you in advance for your replies.
