I opened the back panel to add more RAM but the laptop won't power up now. there isn't even a charging light when I plug it in. No power, no startup.
I've removed the battery and plugged the laptop in, I've tried it with the original RAM setup, no change. The charger is working as I tested it on another HP laptop and the light came on.
Please help.
