Capslock keeps blinking 3 times. This started when i updated the bios. After using it for like 30mins, the laptop makes a sudden buzzing sound then produces a blurred greyish display then shuts down. I tried chat support and they said it is a hardware issue but i want to know first the problem before bringing it to the repair center. Can someone help me out? Any info would be great. Thanks!
Hi PLEASE POST ANY RESULTS. First:- Turn off the computer, press and hold the PWR button for 4 seconds.
Then - Leave only keyboard and mouse connected, disconnect all externally connected devices such as Docking Station, USB storage devices, displays, and printers. Unplug the AC adapter from the computer.
Next - Press and Hold the Power button for 15 seconds to Hard Reset. Rinse and Repeat; Re-Connect the AC adapter.
NOW begin checking/testing/proving the Hardware is fit for purpose. Power on your PC, press ESC (repeatedly), then F2 at the prompt. Choose System Tests (Fast Test does a 4 minute hardware check). AND/OR HOW DO I USE DIAGNOSTICS?
