HP and others have had bad battery history , check at their support website for any recalls. Next, a battery should be dependable for roughly 18mos., anything after that is a gift. If the operation of your laptop was extremely hot, it may have surrcomed to heat damage. HP and others have had poor quality issues with heat involved. Either the charging ckt. is kaput or the battery has been weaken by same. If you can charge the battery elsewhere, do so. Also, note the LED on the charger adapter if it goes out upon connection to the plug-in, bad ckt. or short, very obvious clue. Even with a fully charged battery, the smart ckt. will become false status(not charged) and won't allow operation if the laptop is a type where the battery has to be present, yet be at some 10-15% charged level. Also, cheap batteries or repaired ones can be crap, so don't trust all batteries.
I have a HP Pavilion dv7-1130eg running Vista Home Premium 32-bit.
The problem is that my battery is not detected by the PC. When the problem started, it just said, something like 'CONNECTED, NOT CHARGING' and it was at 0% (sorry if my translations aren't fully correct, I have the Slovak language pack loaded in Vista)
We went to a bunch of electro-shops and service centers and everybody said that the battery is broken. Except at one, they said that MAYBE the computer has something broken so that it can't charge the battery.
Then after a few days...it went changed to 'NO BATTERY DETECTED' and no longer was, 'connected, not charging'.
So what am I supposed to do? HP Battery Check says that there is no battery inside and so does Windows, but PC Wizard 2012 says that there is a battery charged at 255% inside...yeah...255%
I did turn the PC off disconnected it from every thing and took out the battery and held the power button for 30 seconds...nothing!
I did reset the BIOS to defaults...nothing!
I did try to turn on the PC on only battery power...didn't turn on, obviously!
I didn't try to update the BIOS yet.
I hate HP Notebooks...aside from this, it overheats and is extremely laggy (I guess the speed is affected by Vista).
Please help me, thanks.
