HP Probook 4440s Will not turn on. LED light with plug symbol blinks repeatedly and then stops

[chren]

The title sums it up. Recently my probook 4440s lost power (i belive) while I was using it, even though it was plugged in. The LED light near the symbol of a plug was blinking blue, and the computor will not turn on. Ive had this problem before, but usually taking out the battery and letting it rest for a few seconds does the trick. Not this time. Its been off for about 24 hourse now. If anyone can help, it would be greatly appreciate. Thanks!

Hello chren,

When a unit loses power all of a sudden while in use, some bad things can happen.

If you, when you now turn on your unit, you have the blinking LED it can, if it blinks like in a sequesnce, mean that there is something wrong with your unit.

I have pasted a link below that explains in more detail about what theese LED blinking error codes mean.

You CAN try a power cycle reset if the led isn't blinking in secuence but more like a flashlight on a car, just continously.

A hard reset is performed in the following war:

1: Disconnect everything, also the power plug and take out the battery

2: Hold down the power button on the unit for app 40 seconds

3: Reconnect ONLY the power plug and start the computer with the power button as you would normally

If no hardware is damaged this could solve your issue.
