You need to contact Toshiba and ask them which processors are supported by THEIR BIOS. Then, you can select from those processors.
And, that is only possible if the existing processor is not soldered to the motherboard.
An upgrade processor must be socket, BIOS, and chipset compatible.
Also, in my opinion, it provides little value and improvement to make this type of upgrade. Especially, if you plan on going to Windows 10.
Hi Doc, Its a socket G1 so no problem there.
The Core i3-390M is a compatible upgrade just don't know whether the i5 will actually do anything better than the i3. I can buy an i3 for like $22 so no big deal.
I am well aware this machine is probably for the scrap heap but its a project/hobby for me... keeps me off the streets.
The CPU fan died which lead to the problem. I am not looking to upgrade so much is just restore to a good solid machine.
Even with a bad fan the machine was running Win10 Ok with only 4Gb of RAM..before I pulled it into pieces to replace a USB port..
Thank you Amy. Much appreciated.
