Also lately my laptop often shutdown incorrectly because of unstable power supply (i always plug it in withoht battery) does it affect with my case?
 
Hi,

You mentioned that this would happen even if it's connected directly to the AC adapter but without the battery right?
- If it's shutting down by itself while it's just connected to it's AC adapter and without the battery the problem may lie on the AC adapter itself.
- Try to test you AC adapter using a multi tester if it's supplying enough voltage to your laptop.
- If it will still shut down put the battery back in and the AC adapter and observe if it will still shut down.
- If it will not that means it's the AC adapter that is faulty.
