As the subject title says my G3 3779 turns off with battery on 100% after unplugging AC chord.
It started out of the blue, I even turned it on today without the plug connected. I've updated the BIOS ran every diagnostic there is, and all test say there is no issue.
Click the link below and update the bios again.
Also, provide your system service tag number.
I updated the bios again , and now the laptop won't start. It won't even turn on the backlit keyboard.
My service tag is: <Service tag removed>
What are the diag leds showing on the system?
The Real Time Clock (RTC) reset function
Instead of beep codes errors are indicated via the bicolor Battery Charge/Status LED. A specific blink pattern is followed by flashing a pattern of flashes in amber, followed by white. The pattern then repeats.
The system will not shutdown when displaying the Diagnostic Error Codes.
Diagnostic Error Codes will always supersede any other use of the LED. For instance, on Notebooks, battery codes for Low Battery or Battery Failure situations will not be displayed when Diagnostic Error Codes are being displayed.
I got 3 amber blinks and 1 white. It seems CMOS Battery Failure.
how shall I proceed? Do I change it myself? What kind of battery is it?
It is a Coin-cell battery
I managed to replace the coin-cell battery, and everything was working fine, until today.
The laptop does not turn on while un-plugged and with full charge, and turns off if I unplug it.
