Ever since upgrading the BIOS in my system to the latest 2.3.1, the battery life in my system has gone all to ***. I used to routinely get 8 to 10 hours use out of it, and now, if I'm lucky, I get two hours. Tech support has already done an on-site battery and system board replacement, to no avail. I can sit and watch the battery percentage drop in the ePSA screen. System demand supposedly around 2,000 mA, which should yield 30 hours of runtime with the 60 Wh (brand new) battery, but yet goes down to zero in just over two hours. System is also running hot, I notice. All this in the pre-boot diagnostics, so no OS load on the processor.
Anyone else seeing this issue? Last time I updated the BIOS before this was back in April, 2017, which really improved the battery performance.
Any suggestions?
