I have flashed a BIOS [admin edit] from Serg008 to my T410 2537-DA3. I had the latest factory BIOS before. Flash was successful, i disabled the TPM because the beeps at startup.
Then i realized, that i cannot read CPU speed from the OS (Ubuntu), and the battery isn't charging.
I can see on the indicator, when it is inserted or not, but no charging. I installed TLP, started a calibration, but it only discharged the battery, and charging is not working. (Or if it is working, BIOS does not see what charging circuit is doing.)
EC ROM is 1.18, in addition.
I tried to flash factory BIOS, but it cannot be done with 0% battery. I'm afraid to flash FL1 and FL2, as i have two FL2 files extracted from factory flash.
Have someone seen a bug like this before? Can someone tell me how to flash FL1 and two FL2's (and .PAT files) with Winphlash? Or force the boot CD image to update? I ned to revert the factory BIOS to check that the charging circuit is OK.
Thanks in advance
