I turn on my laptop and the caps locks blinks once then it turns off immediately... The only way I can tell it's coming on is the light in the side... I have tried to hard reset it but to no avail.. it was working fine last week

Hi! @dregon, Thanks for stopping by the HP Support Forums!

I understand when you power on the laptop the laptop shuts down automatically and the caps lock blinks one time repeatedly.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

Are you able to access BIOS or F2 system diagnostics on your PC?

Splendid analysis and remarkable patience shown. It is immensely appreciated.

One blink on the caps lock- indicates the CPU on your laptop is non-functional and you have to get the laptop serviced.

Refer this article to know more information about blinking lights on your PC.

However, Try few steps recommended below and check if it helps.

To perform a hard reset on a computer with a removable battery, use the following steps:
Turn off the computer.
Remove the computer from any port replicator or docking station.
Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
Unplug the AC adapter from the computer.
Remove the battery from the battery compartment.
Press and hold down the Power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory.
Insert the battery and plug the AC adapter back into the notebook computer, but do not connect any of the peripheral devices.
Press the Power button to turn on the computer.
If a startup menu opens, use the arrow keys to select Start Windows Normally, then press the Enter key.
After reconnecting each of the peripheral devices, run Windows Update and HP Support Assistant to update all device drivers. See Updating Drivers and Software with Windows Update (Windows 10, 😎 and Using HP Support Assistant (Windows 10, 8, 7) for more information.

If the issue still persists after trying out the steps, It is a hardware issue with your PC.
