Please try removing the battery then attached the ac adapter and see if the same thing happens. It is possible that the AC adapter is faulty already if it doesn't isolate the issue. Please let me know if the result. Thank you and regards.
How about this step, try to turn off the laptop itself. Remove the cables and battery just like what you did before, then press and hold the power button for 10 seconds. Then, reinsert the cables and battery on the laptop and then turn on the computer itself. If the laptop restarts, shuts down or freezes with the AC power cables, two things that you should seriously consider. It might be the power cable itself, AC cable port or the circuitry going to the motherboard. And since you have cleaned out the fan and heat sink, you have isolated that problem. Have you plug-in another power cable on your laptop? If yes, then check if it works. Otherwise, the main issue is that the AC port is loose or the circuitry of AC adapter going to the motherboard is not not working. You can re-open the unit and check the circuitry from the AC port going to the motherboard. You may check the circuitry from AC port to the power supply if it is ok. If symptom persist, please contact your local dealer...
Hi, There is a possibility that the battery is defective.
Turn the laptop off and remove the battery and AC power. Clean the brass contacts on the battery and the laptop. Plug in AC power only, boot the laptop up without the battery and go into the BIOS and set the BIOS to default settings. Save the changes and let the laptop boot into Windows. Once in Windows power down the laptop again and remove the AC power. Reinsert the battery and AC power and boot the laptop up. See if that has helped.
The problem lies with the power supply system either in the power adopter or inside the laptop. When AC power is plugged in, the system shows that the battery is being charged (Yellow Light Indicator switches ON) but practically niether the battery is usually being charged nor the computer is being run by the AC power. Its a little bit of energy left in the battery that keeps running you computer for some time and as soon as the battery is discharged the note book shuts down by itself.
However, the Taskbar battery indicator gives the correct picture of battery charge and the charging process. Better rely on that.
Its a hardware problem pertaining to power supply and charging system and doesn't have to do any thing with Mother board, RAM, Hard disks or other hardware installed in the PC.
Do tell the above details to a repair workshop man to rectify the problem.... Best of Luch
Hope you doing good.
Please try the following solution :
1. Disconnect the power cable.
2. Take out the battery
3. Keep holding down the power button for 60 seconds.
4. Put the battery back in.
5. Connect the power adapter
6. Make sure the Power adapter is switched on and laptop is on AC Power
7. Wait for 5 minutes and try to restart the computer
8. If it still doesn't starts.
9. Hold down the power button for 60 seconds with AC adapter and battery connected
10. Try to restart now and check.
11. If it still doesn't switch on
12. Take out the battery and run on only Ac adapter and restart.
Please advise if this still doesn't helps.
