I purchased my Lenovo G500s in 2013. Over the years it had lost few screws on back and the back cover (chassis) was also broken. I tried replacing the back cover myself with a new one ordered from Amazon. It was working perfectly fine before replacement but after replacement its giving me following issues-
- The screen is blank after pressing the power button, though the power LED and battery LED are glowing white. On connecting with an external monitor through HDMI I am not getting any video output on the external monitor also.
- The laptop is giving a beep sound on removing the charging plug and also on re-inserting the charging plug every time.
- After removing the back lid I could see that cooling fan and hard-disk are running and GPU and CPU are warm on touch.
