Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure:
CAUTION: This product contains components that are easily damaged by ElectroStatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC.
1. Disconnect all cables from the computer, including the power cord.
2. With the power cord disconnected , press the power button on the front of the computer for five seconds.
Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
NOTE: If the power supply fan makes an inconsistent grinding sound or stops and starts erratically, replace the power supply.
3. With the power cord removed, flip the red voltage selector switch to the opposite position. Wait about five seconds, and then switch the red voltage selector switch back to its original location. Ensure that the voltage selector switch is on the correct setting, 115V for North America.
Performing this step ensures that the voltage switch is engaged and set correctly for your country/region.
4. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet and test to see if the computer can turn on.

If you didn't accidentally unplug the four pin connector near the CPU, you need to replace the power supply. This is actually a fairly common occurrence with the cheap ATX power supplies being tossed into systems these days.

Power led on hp monitor flashing


mham2525, Did it have a "perfect" picture on it yesterday? You do know that if the COLD-CATHODE-FLUORESCENT-TUBES that are hung on the rear of the LCD PANEL fail to light, all you get is a BLACK screen to look at!!!!! OMG, What shall I do now???? It sure would be nice if all we needed to do was remove the cover and then screw-in 4 new CFL light bulbs into our monitors. YOUR UNIT WILL NEED TO BE TROUBLESHOOTED AND REPAIRED. MOST LIKELY A SMPS/INVERTER BOARD FAILURE. CALL HP TO SEE IF THEY HAVE A SWAPOUT PROGRAM. Bye for now. lmistyrel @aol.com

My hp pavillion will not power all the way up


What do you mean it powered on to the blue light?
Does anything show up on the screen?
Does the system usually beep when it starts? If so, does it beep now?

Hp pavillion will not turn on, took battery out and put back in still not working. blue light around power cord on and blue lightening bolt flashes


Hi Iceprincess5

The three flashing lights indicate the battery is dead. Since it still wont power up with the cable plugged in I'd say the port has gone. Try wiggling the adapter about in the port to see if it begins to charge. If not then you would need to take it to a laptop repair centre to get a new dc port soldered on or buy a docking station.

Power supply light flashing.


Computer power supplys are modular replacement fixes. Better to replace the whole thing then try to repair.
