    I researched on the web and most posts said it was likely the power board which was also the cheapest to buy and replace myself.
    I did see a few posts that said it could be motherboard.
    Everything else works on the laptop, so could it still be the motherboard???
    Thanks!

    What gives you the indication that it isnt your motherboard and it its your power switch? It has been my experiance that motherboards go out just as fast as its connected devices.

Guy above me is a douche. I already reported him...

Anyways, I didnt notice that you said that your LED lights lit up. Your power button is working fine. Its something wrong with your motherboard/video. hook up your laptop to a regular monitor, see if you get any video output. Also you should know that there is a recall on the DV6000 laptops. If you go to the hp website, it has all the information on there. This will allow you to extend your current warranty for another 2 years, however, it is only if you are having the defect in question happen to your computer.

Tell your tech to look at the AF4814 chip below the left ribbon cable. And replace it. There are no spec sheets on that chip available. but it appears to be a dual 30v N-channel mosfet. They cost about 49 cents if you can find it. The Anachips number does not cross to another manufacturer that I have found yet.

    Update: The chip is no long Anachips since Anachips was purchased by DIODES.COM and the chip number is now AO4914 Alpha&Omega Dual MOSFET -30V with (1) Schottky diode.

I have installed a new motherboard in an acer case. The power cable from the switch on the front of the case will not connect to the board. Can anyone help? Thank you


You should read the motherboard manual, for cabling:
1. Power SW
2. Reset SW
3. HDD led
4. Power led - and power led +
5. Speaker

Cabling scheme, also written on the motherboard.

If the Power SW not installed the switch on does not work.
If the Reset SW not installed the switch reset does not work
If the HDD led
not installed the hard drive light (red) is not lit
If the Power led (+/-) not installed the power light (yellow) is not lit
If the Speakers are not installed, when the computer is on the beep sound is not heard.


I hope this information helps.

> power led,

Runs to the LED (Light Emitting Diode) labelled "power" on the front of your computer-case

> H.D.D led,

Runs to the front-panel LED that lights-up whenever the Hard Disk Drive is being used.

> reset sw,

Runs to the "reset" button on the front panel.

> speaker

Runs to the internal speaker

Very briefly touch a metal-tip screwdriver between these 2 pins.
If the computer powers-on, you've found the "power" connector.

Hi,

there is a possibility that you may have pulled off the power switch, to motherboard Connector.
This will be at the bottom right hand-side of the Motherboard.
You should have a 2 cable connector for. pwr/sw Power Switch. hdd/led Hard-Drive led. rst/sw reset Switch.
Check those First. if you didn,t remove the power lead, before attempting any work. you may have arced a current, and damaged the motherboard Or PSU. check the Fuse In The Actual plug lead. to determine the actual power Switch, without a multi-meter. remove the power lead, from the Computer. remove the power/sw connector From motherboard, And Bridge the power/sw with A plastic jumper Block. then replace power lead, and should boot up. If it does the fault is the actual power switch faulty.

Wont power up


If you are getting absolutely nothing, and it seems you have checked all the obvious, then I guess its just the board given up

HP Laptop sound and power button trouble


You don´t have to replace it. Just cut about 1,5 - 2 cm off the end (that´s where mine was broken) and scrape the tracks free with a knife. Then but a small batch of tape behind the end so it will be held in the socket. That´s it, a 10 min fix.

Power LED on but no boot up


it could be your power switch, veriy that it isnt the power supply by

1.) un-plug it from the main board
2.) look at the main board connector(one coming of the power supply)
3.) you should see green wire and next to it a black one
4.) using a paper clip bridge the too wires
5.) if it works proceed to net step if not get a new power supply

to check case switch and board switch

1.) plug in power supply to main board
2.) look at the pins where the power button connects to
3.) using a metal object (blade screw driver) bridge the pins

if the board should start up>
then its your power button on the case that is bad, you can try to repair it, chage it or buy a new case,

if it doesnt work.
1.) ensure that jcms(jumper to flash the bios) is set correctly
2.) unjack each drive one at a time to see if any is causing stalling
3.) get a new main board
