Question about HP Compaq 8510w Notebook

2 Answers

My hp 8510W mobile workstation has suddenly stopped working. I powered down normally. When I tried to start it up again, the power LED blinks 8 times then stops. There is no power going into the system, either mains or battery. Can you help?

    Thanks, I tried taking the battery out and reconnecting. In this case it is completely dead. When I put the battery back, I get the 8 blinks again. I cannot test the DC convertor as I need to get a multimeter. BTW I am based in Switzerland with 220V power supply. The notebook power supply is set up for that. It is possible I may have had a short when plugging into the mains socket here. Switzerland has small 3-pin plugs and I noticed a pop when I plugged in, although it worked normally afterwards. After powering down it would not come back up. Would this be the probable cause?

Indeed eignt blinks is a power problem, but this does not mean that the battery or the power adapter are faulty.
Eight blinks on HPs is fault code. Itmeans that there is power getting to the computer , but that the voltage out from the DC to DC power converter has an incorrect value.
Naturally this can be caused also by a faulty power adapter , or by a shorted battery, but this is quite unusual. When you have this condition, you usually need to replace either the motherboard or the power converter board when this is separate.
Before replacing DC power converter, remove battery and unplug the laaptop, leaving it unplugged for twenty or thirty minutes. Connect AC adapter back and test the laptop with no battery.
That will tell you if the battery may have caused the problem.

To test the DC adapter, read Volts on DC adapter out. This can be done using a multimeter. Volts must be within +/_ 0.5 Volts from the value on specs.
You may find out that the AC adapter and the battery are fine, and computer is still in same fault condition.
In that case the laptop must be taken apart to replace the faulty DC converter. The part can be ordered from HP.

This is not a good sign. The error code is saying there is a problem with the system board or bios. Basically they will need replacement.

I don't know if this will work but try it and hope it does. Go to this web page and follow what it tell you to do. It might reset it enough to get it running.

I don't think you will get it working from the error code so before you take it back to the store or send it off to HP have a local shop pull the hard drive and back up your information. While most repair depots do try not to wipe the drive sometime they do need to and they don't do backups so all of your data is gone.

Wish I had an easy fix for you.

I have an 8710 workstation and it has worked fine for many months. Recently I've been having problems powering it on. I use a docking station and when I try to power it on in the morning -- the power LED...


Flashing orange light generally indicates battery low charge could be your battery at fault
the next time you try and power on and it doesnt work, take the battery out (unplug AC) and try to run just on AC power
hope helps, let me know if can help further

WILL NOT CHARGE.AC ADAPER IS FINE ANS ALSO THE BATTERY IS FINE


Does the AC adapter works fine wth other computer? Does the power light glow at the power cord connection. It can be a motherborad issue for the power port that may be loose. Try changing the angle of the power cord and see if it works.

Panasonic Th37PE30 Viera plasma stopped working


here is a complete list of all codes for panasonic tv's rgeardless of model if its panasonic it is these codes

1 Blink SOS: This shutdown operation is usually caused by a lack of communication between the A and the D boards.
1 Blink SOS: This shutdown operation may be caused by the improper connection of a SS board connector to the panel.
2 Blinks SOS: Pin 87 of the MPU IC9003 monitors the 15V line. During normal operation, the transistors Q9053 and Q9054 output a high to pin 87. If the 15V line is missing or shorted, a low is provided to pin 87. As a result, the unit shuts down and the power LED blinks 2 times.
3 Blinks SOS: IC9807 is a 3.3V regulator located on the D board. Its output is monitored by IC9003. If the 3.3V is not present at pin 86, the MPU shuts down the unit. The power LED blinks 3 times.
5 Blinks SOS: Pin 85 of the MPU IC9003 monitors the 5V line. During normal operation, the transistors Q9051 and Q9052 output a high to pin 85. If the 5V line is missing or shorted, a low is provided to pin 85. As a result, the unit shuts down and the power LED blinks 5 times.
6 Blinks SOS: Pin 90 of the MPU IC9003 monitors the status of the SC board. During normal operation, the transistor Q6581 and IC6581 output a low to pin 90. If the SC board becomes defective, a high is provided to pin 90. As a result, the unit shuts down and the power LED blinks 6
6 Blinks SOS: 6 blinks of the power LED may also be obtained from pin 3 of IC9003, the DRV_RESET input. The D board provides the 5V source needed to power the C boards. On the C2 board, the 5V is routed back to the D board via connector C20/C10, C11/D31 causing pin 3 of IC9003 to be high. If 5V is not routed back to the D board, pin 3 of IC9003 goes low. The set goes into shutdown mode and the power LED emits 6 blinks.
7 Blinks SOS: Pin 93 of the MPU IC9003 monitors the status of the SC, SU, SD board. During normal operation, the photo-coupler PC6480 outputs a low to pin 93. If the SC, SU, or SD board becomes defective, a high is provided to pin 93. As a result, the unit shuts down and the power LED blinks 7 times.
8 Blinks SOS: Pin 91 of the MPU IC9003 monitors the status of the SS board. During normal operation, pin 8 of connector SS23 outputs a low to pin 91. If the SS board becomes defective, a high is provided to pin 91. As a result, the unit shuts down and the power LED blinks 8 times.
10 Blinks SOS: The SUB5V and DT9V sources created on the A board are monitored by IC1100. If they are not present at pin 30 and 34, the MPU shuts down the unit. The power LED blinks 10 times.
10 Blinks SOS: The F_STB_15V of the P board, as well as the derived SUB5V and DT9V sources are monitored on the A board for excessive current. If a short circuit is developed in one of the supplied lines, pin 114 of IC1100 receives a high. The SUB5V and DT9V lines are also monitored for excessive voltage. When an over-voltage condition is detected, a high is also output to pin 114 of IC1100. The DT9V is provided to a DC/DC converter to create the BT30V for the tuner. If the BT30V becomes excessive, a high is output to pin 114 of IC1100. A high at pin 114 of IC1100 causes the unit to shutdown and the power LED to blink 10 times.
