Presario CQ61 doesn't detect the AC adapter

September 10, 2011 at 01:11:26
Specs: Windows 7 Home, AMD Sempron

The computer won't install service pack updates because it thinks the system is running on the battery. If I remove the battery while the system is running and connected to the power adapter, it detects the power adapter and continues with the updates. The adapter charges the battery correctly and measures the correct voltage. It is like the power manager is crazy.

While your laptop is being used on mains power on a regular basis or for long periods you shouldn't leave the battery attached to it anyway. If you do, the battery will quickly start to fail and will no longer hold a charge.

Charge up the battery then remove it until you really need it where there is no mains power available.

Your answere is totally unrelated to the problem. I noticed this morning that the system would not boot while the battery was removed.

What was the original error message when the service pack wouldn't install?

Something like; The laptop is running on battery power. Connect the power adapter to complete the installation. The power adapter was already plugged in and the light next to the jack was lit.

The system has all the drivers. I think there may be a problem with the power management chip in the battery or the laptop. Sometimes there are utilities to reset the power management chip. Sometimes you can drain the battery completely with a load resister to reset the chip. It works well enough for now.
