HP 2710p Battery issues resolved

Just over 12 months ago we purchased 55 HP 2710p Tablets with Vista Business for our Teaching Staff. The machines have generally been pretty good but we had some unsolvable battery issues that we couldn’t solve ourselves and eventually opened a support case with HP to try and rectify. We had various problems with batteries not holding much, or any charge and some machines that wouldn’t recognise their battery at all and would only work with the AC adapter connected to the power. If we swapped batteries around between machines they would start to work normally again and the battery would charge and be usable, however, it wouldn’t be long before the machine would have battery issues again.

HP Support got us to run the Battery Check and Health Check on some effected machines as well as machines that hadn’t had any battery issues and send them the .XML files that were generated for their engineers to check. We also sent them the .nfo System Info files from MSINFO32.exe for these machines.

hpbc
C:\Program Files (x86)\Hewlett-Packard\HP Battery Check\hpbc.exe

hphc
C:\Program Files (x86)\Hewlett-Packard\HP Health Check\hphc.exe

Running these two applications generates two logs files that are stored under HP Active Support

The Health Check managed to find that the machine’s were missing an update for the HP Quick Launch buttons, but didn’t find that there was an updated BIOS available for the 2710p. The HP Health check seems to be pretty good at finding updates for HP software and drivers, but not so good at finding and recommending firmware updates. The issue has been resolved by updating to the latest BIOS, which for us was F.13, F.14 is now available. All machines that had experienced battery problems have now received the BIOS update, and have not had any problems with batteries holding their charge or not being detected since then.

  1. dude, you are my hero. I checked my bios and it was version 7! Updating took two different flashes since it made me update to 10 first. I was about to spend $40 on a battery and this fixed it!
