I have just repair my laptop few days ago, and changed my motherboard. When i start my laptop yesterday, it was okay and work well until i use my laptop today it suddenly shut down. I try to start my laptop and before the windows could appear, it shut down again. I have it for 5-6 time and the same thing happen. then, i took the battery off and start the laptop like normal and it works but there's a notification saying there a hard disk problem and i need to do a back. I actually not sure what is exactly happening to my laptop, i have repair it and not willing to spend my money anymore .
If the laptop does boot up normally without the battery and is just connected directly to the AC adapter, that could only mean that the battery needs to replaced already. Do also try a different AC adapter that has the same voltage and see if the same problem will persist or not. If you're getting an error about the HDD, unfortunately I would suggest you proceed with the back up just to be sure.
Here are some other troubleshooting steps that may help if ever the laptop will not boot up.
- Start by doing 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.
- If this will not work, do test the AC adapter if it's working properly. Remove the battery and power the laptop with just the AC adapter connected and see if it will boot up or not. do also try a different AC adapter that has the same voltage and see if it will work or not.
- Proceed with reseating the RAM's if trying a different AC adapter will not work, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If it will still not work, connect an external monitor and see if you'll get any display from it. If there's a display on the external monitor that could mean that the problem is the built in display.
