Troubleshooting & How-Tos
Notebook - Battery not detected
Method 1: Reconnect your AC adapter and your battery
One of the simplest and most effective ways to fix this issue is to reconnect your AC adapter and your laptop battery.
Notebook/Desktop – Fan not spinning
Method 1: Restart your computer
The CPU fan can easily be stopped with a finger or debris since it does not have much torque. To prevent the fan wiring from frying or any other damage, your fan will stop spinning even if you remove your finger or the debris. Restart your computer to clear this error.
Notebook/Desktop - Keypad not functioning
Reboot Your PC
If you followed the above advice, you'll have already done this, but just in case: have you tried turning it off and on again? A reboot corrects a thousand ails, as my old IT manager used to say.
