[Azirul]

While playing COD its suddenly hang, at first there is repeating dying sound but screen blank (black). After 5-10 min i got bored i try to forced restart (pressing start button + hold it) but nothing happen. So i close the laptop screen then sound cleared. But till now if i connected to charging station it will move the fan but laptop wont start

A hard reset may fix the problem

• Turn on the computer by holding the power button down for 20 full seconds then release.
• Press the Power button one more time (if necessary) to start the computer.
• Tap the ESC key about once a second after you see the LEDs on the keyboard flash.
• Press F2 to run diagnostics: (v) 2.6 or later is recommended.

Probably overheated, use an air duster to blow out the vents.

Let me know what you find out.  Do not try a BIOS update if you have problems.
