Been having a really weird issue lately where 99% of the time, when I shutdown or sleep my PC for the night then come back the next day, when I press the power button, it doesn't turn on. I can tell I still have power from the lights on the motherboard, but it won't wake up.
Remove the battery and then hold the power button for at least thirty seconds. Connect the new battery and plug in the power adapter. Let the battery charge for a few hours. After a few hours, press the power button to see if the notebook reacts.
Disconnect the laptop from the power source. Remove the battery if it's removable. Hold down the power button for about 15-20 seconds. Reconnect the battery and plug in the power adapter. Try turning the laptop on. Thanks for your feedback, it helps us improve the site.
The power supply is leaking mains voltage on to its output via capacitive coupling. The current is small, and not hazardous, but your fingers can be very sensitive to this. Perfectly normal.

How do I fix a faulty battery?
First is to do a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again with the battery and charger. - Next test to try would be to remove the battery again and connect just the AC adapter and see if it will boot up or not.
Hard reboot holding pwer button and One key recovery button for up to 120 seconds, no battery and no adapter. Tried remove WiFi card, hard disk, cd-rom, one by one and all together. Disconnect laptop screen (video and power cable) in order to connect an external one. Funny thing: if no memory modules are on, BIOS will give correct beep code.
No I think whatever is bad has always been bad. The battery provided power until it ran down. Now it is out of juice and if the AC adapter is no good or the power jack is no good then it will not start. Was this reply helpful?
