Battery and AC Power problem

December 23, 2010 at 00:07:33
Specs: Windows 7
I have a HP Pavillion dv7-1273cl laptop for over a year and it was running and charging fine until about a few days ago. As of now, it can seem to be able to charge. The power tray icons keeps displaying as "41% available (plugged in, not charging)" even though the AC power is connected. Furthermore, whenever I remove the AC power, the OS automatically shuts down and cannot be turn on until the AC Power is connected.

I have deduced that it is a hardware problem and not an OS problem, and have tried various fix such as uninstall (and reinstall) the "Microsoft ACPI-Compliant Control Method Battery", removing the battery, etc, but none has worked.

I don't know if this might be the cause of this problems, but I am currently traveling to a country using 220V outlet, while the power of this laptop is 110V. However, I has been using a 110V transformer ever since I got here and it was working fine before.

Thanks so much for your help in advance, and I will provide further details about the laptop as you needed.

HEY my freind before u do anything, try to change a battery first. i mean not purchasing borrow or something.
i think the problem is on your battery. pls do not change the voltage into 110 or something. when u use a charger for a long period,even if the battery is full. the battery will degrade it's capacity for example if ur battery can hold 3 hours for applications without charging, after a few days it can hold 2 hour something mins. and continuing charging, the charger will kill the battery when you unplugged.
that's why am saying try to check changing the battery before u do anything
if there is no solution, post something and i will read it

It does sound like the battery. A typical rechargeable battery lasts for about a year before you start seeing big performance issues with the battery. You should also replace the ac adapter as well. and ebay have those for about like 10-15 bucks and you can also get the battery from there as well.

As for the charger being hooked up to a 220v outlet, most laptop can automatically switch from 110 to 220. To verify that it can, look on the bottom of the adapter and if it says under input 110-220v you should be fine.
