Over your head? No shame in that. Request a repair and I'll take it from here.

This guide offers an all-encompassing solution for scenarios where there's no visible physical damage, yet the system won't turn on and the power indicator flashes intermittently.

Without Opening the Device

  1. Turn off your computer.
  2. Disconnect all cables and peripherals from the PC.
  3. Remove the battery, if applicable.
  4. Hold down the power button continuously for a full 60 seconds.
  5. After 60 seconds, release the power button.
  6. Make sure no other devices are plugged in, including the battery.
  7. Connect the power cable.
  8. The system should try to boot, but this may take some time while it reconfigures itself.
  9. Watch for the battery LED (laptop) or power LED (desktop) to flash in a repeating sequence.
  10. If it boots up successfully, great; we are done!

If the system still doesn't boot, continue to the next section.

With Opening the Device

  1. Consult your manual for disassembly instructions, especially if the battery is installed inside the laptop.
  2. Once you've unplugged or removed the battery, locate the BIOS (CMOS) Battery. Disconnect this small battery if possible; if not, short the contacts with something metal for 10 seconds.
  3. Find the RAM, typically located next to each other, either vertically (desktop) or horizontally (laptop). Follow your manual's instructions on how to remove them.
  4. If you can't remove the RAM, go to the next step.
  5. After removing the main battery, CMOS battery, and RAM, hold down the power button for 60 seconds.
  6. Carefully put your device back together in reverse order, taking particular care when reinstalling the RAM and BIOS battery. Always follow the instructions in your manual!
  7. Once reassembled, reconnect only the power cable and try to boot the device.
IF, AFTER FOLLOWING ALL THESE STEPS, YOUR DEVICE STILL WON'T TURN ON, IT MAY BE TIME TO SEEK PROFESSIONAL HELP.
