Hello everyone
I have been working on this laptop mentioned in the title, it initially had a shorted capacitor. After I replaced it, the thing started working again, but there is still another problem. The laptop was running off a charger, the battery was reporting 96% charge... but when I unplugged the charger, the laptop died. I've measured the battery voltage - 0V. I think it is locked. (Screenshot from batterymon, below).
I've ordered a new 3rd-party battery, but I think there's something wrong with it too - the laptop boots, but the battery isn't charging. Also,... -
Hi everyone,
I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.
Some history:
Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.
As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)
Now, with a new battery the system will start up and run off... -
Hello,
Please i need help from you how to check what is bad on this device.
Laptop turns on normally on charger or on precharged battery, but is unable to charge - in system shows charging but not charging.
Originally was blown dual mosfet near gpu.
EDIT - after few mins on charger windows says 100% chaged with exclamation mark and something like "please check charger"
Charger is new original 100Watt
Motherboard LPM-3 MB 19770-1
Charging is BQ24780s
