HP Recommended

SCENE: I started my laptop for some normal work and then I simply plugged in the charger for around 20 minutes(Laptop was in sleep mode). later I came to work again opened the lid and pressed the power button for awaking it from sleep, NO RESPONSE.

I plugged it again, NO CHARGING BLINK.

I re-seated the Battery, NO RESPONSE.

Later i checked the Internet i found that it might be the CMOS battery I took it out and checked, NO CURRENT IN CMOS.

Then I replaced it but still I am facing some problems, they are:

LAPTOP IS NOT CHARGING

CHARGER BLINK IS NOT BLINKING

HOWEVER IF DO A HARD START(removing ram, battery and CMOS and press power button for 30+ seconds), The screen shows HP boot logo and then CMOS checksum invalid error 502 press enter to reboot.  I tried both things pressing enter and not pressing enter both leads to same result= THE LAPTOP SHUTS DOWN. 

 

NOW I DON'T KNOW WHAT TO DO, I TRIED EVERYTHING AVAILABLE ON INTERNET BUT THERE IS NO CASE SIMILAR TO ME.

PLEASE HELP 🙂
