I have an Asus N55SF running windows 7 for a few years now and recently my battery started dying instantly, so I got a replacement online. I believe straight away there were some issues, for instance it was stuck on certain percentages (for instance 49%) no matter what and took ages to calibrate. However eventually I got it working for a few days. It powered my laptop fine and was working (even when the percentages were stuck), but yesterday it once again got stuck, this time at fully charged 100%. I thought I would let the battery discharge and charge it overnight, so I waited it until my laptop died and set it to charge. However, today even though it was showing as fully charged, the laptop died within seconds after I unplugged it from the charger.
I downloaded BatteryCare and had HWMonitor already installed, but they are showing some weird numbers. BatteryCare shows the wear level as 0.00% and other things that HWMonitor is also showing, which seem to indicate they aren't getting the correct readings.
The HWMonitor log reads this:
Hardware monitor Battery
Voltage 0 9.31 Volts [0x245D] (Current Voltage)
Capacity 0 48400 mWh [0xBD10] (Designed Capacity)
Capacity 1 707245 mWh [0xACAAD] (Full Charge Capacity)
Capacity 2 707245 mWh [0xACAAD] (Current Capacity)
Level 0 n.a. [0x64] (Wear Level)
Level 1 100 pc [0x63] (Charge Level)
I am wondering if this might be an issue caused by my charger or if it is the battery that is faulty? Should I return it and get a replacement? (Or even worse, is something wrong with my internal hardware on the laptop)?
Obviously this is all quite vague, but I can supply any other information. I have tried deleting drivers and reinstalling them, also tried turning everything off, unplugging everything and holding the power button for 30 seconds but neither worked.
Thanks for any help!
