Looking at the battery details in PM, it shows 100% all the time and the status reads Discharging (with ac). It's still running the tool, the battery shows 100% charge, battery icon on the taskbar has the zig-zag through it (indicating something is running), but it has not discharged, recharged, restarted, etc. The other evening, I decided to run the Battery Gauge Reset function in Power Manager. I have opened up the case, cleaned out dust etc., and put it back together. I plug back in the AC and see 0% available, let it charge back to 100% then the same happens. It can show 4+ hours left in the battery, then suddenly shuts the machine down.
Recently, the (extended life) battery power seems to fluctuate in performance. I have an X61s that I have been using on and off for several years.
