What to do if my HP Laptop does not boot on AC or battery?

If your HP Laptop doesn't boot when connected to AC power or running on battery, try these steps: Verify the power source is working. Reset the computer by pressing the system-off switch. Turn on the computer by pressing the blue sleep button. Disconnect the AC adapter and remove all batteries, then reconnect the power. Remove all but one SDRAM module and try again. Reinsert any other SDRAM modules and try again. The issue might be related to the AC adapter, SDRAM module, CPU module, power supply PCA, display interface PCA, motherboard, display assembly, or hard drive.
