I am newbie and my English is bad(sorry).
Few hours ago I bought used ThinkPad R400.
Windows 7 dxdiag: https://www.ultraimg.com/image/Zmdp
I noticed that it has Intel Core2 Duo P8700 CPU, but it is not listed here: https://www.thinkwiki.org/wiki/Category:R400 . I want to replace BIOS with libreboot and in official page(https://libreboot.org/docs/install/r400_external.html) writes:
but there is nothing about P8700.ThinkWiki has a list of CPUs for this system. The Core 2 Duo P8400 and P8600 are believed to work in libreboot. The Core 2 Duo T9600 was confirmed to work, so the T9400 probably also works. The Core 2 Duo T5870/5670 and Celeron M 575/585 are untested!
The battery was totally dead. I found this one on Amazon: 33+ ... R400 Laptop Battery Compatible IBM Lenovo Thinkpad 14" Widescreen Notebook ... 10.8V 5.2Ah/57Wh
Is it ok that current battery "NOM 14.4V 2.6AH 38WH" and new one 10.8V 5.2AH 57WH???
And also looked for new US layout keyboard on Amazon: Eathtek Replacement Keyboard for IBM Thinkpad ... R400 ... Series Black US Layout
