Samsung NP900X4C not accepting charger but runs on battery
2 year old laptop stopped accepting the charger during normal use.
The LED which indicate green for full charged battery and red for charging is no more working. The battery is draining in Windows which mean the computer is not recognizing the charge anymore.
Following is tested:
- Charger voltage output.
- Loose connection from charging plug to mortherboard. Connection is perfect
- Resetting battery with the button on it
- Memtest+ on the memory
- Battery calibration in BIOS (recharged with temp solution below)
Temporary solution found:
Unplug mains, battery and BIOS battery. Remove ram memory and put it all together. This makes everything work for a few hours and then it all starts over again. There is no instability, the system is running perfectly fine!
