I do not see anyone having problems with the battery life after 1.4 BIOS update, but I have. On a 1.3 version, my battery lasted about 5.30 minutes with normal use. After 1.4 BIOS update I could not get more than 2.30min with the same usage. Now, 1.5 update has been released, but I still have the same problem.

I tried by deleting battery drivers, removing the battery and returning it back and nothing helped. Does anyone have similar problems?
