In Oct 2018, I upgrade BIOS on my x250 Thinkpad to version 1.33 as suggested by Lenovo but have since regretted this move. My trackpad, trackpoint (the little red thing), keyboard and speakers have not worked since then. OS is running Win7 64-bit. Upon boot-up, the keyboard works for a few keystrokes at the password field, and then DIED! Sometimes it lets me past the login phase and when I edit a document, it dies after a few sentences. The trackpad and trackpoint was working before the BIOS update. The speakers do not work now but earphones are ok, so my soundcard is probably still intact.
It has brought a great deal of inconvenience of late, and the X250 laptop is now almost useless. I am using an external keyboard and mouse to circumvent the issue. Probably the internal drivers have been over-written or corrupted.
Any way to salvage my X250? How to rollback the 1.33 BIOS and revert to a working version without more devices failing. Appreciate the support. Many thanks!
