Power LED flashes Red four times, once every second, followed by a two second pause, and the computer beeps

four times. (Beeps stop after fifth iteration but LEDs continue flashing.)

Cause Solution

Power failure (power supply is overloaded). 1. Check that the voltage selector, located on the rear of

the power supply (some models), is set to the

appropriate voltage. Proper voltage setting depends on

your region.

2. Open the hood and ensure the 4- or 6-wire power

supply cable is seated into the connector on the system

board.

3. Check if a device is causing the problem by removing

ALL attached devices (such as hard, diskette, or optical

drives, and expansion cards). Power on the system. If

the system enters the POST, then power off and

replace one device at a time and repeat this procedure

until failure occurs. Replace the device that is causing

the failure. Continue adding devices one at a time to

ensure all devices are functioning properly.

4. Replace the power supply.

5. Replace the system board.

The incorrect external power supply adapter is being used on

the USDT.

The USDT power supply adapter must be at 135W and use

the Smart ID technology before the system will power up.

Replace the power supply adapter with the HP-supplied

USDT power supply adapter.
