    so, is replaceing the motherboard the only option when it no longer powers on? I am two months out of recall coverage for my laptop. I would like to fix it still. HP says it would replace the MB, and that will cost me 400. I can find one on ebay for half that. Yet a cheaper repair seems posible since I had just shut down from windows when this started. I can replace MOSFET or diodes, I just don't know where to start.

    I hear that a chip overheats on this laptop, and causes all these problems, motherboard 436450-001. HP replaced them with a 444002-001 I believe. Well, I have the first of these boards, PQ40 looks like it was the chip that got too hot, I can't find a datasheet or a place to get replacements, I was going to swap it and PQ41. Then do the BIOS update that HP put out to fix this issue. Anybody know if this was the chip that overheats? Should I just get a new board?

My suggestion you bring that to the service center for the expert operation because all part of your laptop is highly sensitive with the electro static that will cause for the damages of some component..

How to troublehoot a Portable compouter that will not POST (Power on Self-Test)

Basic troubleshooting for a portable no post is a fairly straight forward process.
  1. Disconnect any external devices and power the system on, see what symptoms occur. Does the system have power? Does it have any Video? Does the system flash LED lights or beep?
  2. If the system is getting power but not starting, and not indicators give any troubleshooting hints, then we simplify the system by removing all items we can and see if we get basic function. Items to remove are Battery, RAM modules, Wireless Cards and the drives. Depending on the design, some of these can't be removed by the user but most can be removed.
  3. If the system will now power on and give some sort of error (LED FLASH, BEEP etc) then Add 1 RAM module back to the system and see if you get video and errors about not being able to boot. If you do, start adding items back to the system one at a time and identify the failing component.
  4. If nothing makes any successful boot, then most likely failure is the mainboard (Motherboard) of the system.

Cannot get an HP G60 120US running Win Vista SP2 to recognize wireless internet connection. Wireless button will not turn blue (on), even after a two-minute power down reset with the battery removed...

I've had similar problems with wireless cards refusing to turn their light blue until the driver was updated via windows update. Obviously I had to do this using a wired connection. Try connectiing with a wired connection and udating until windows update tell you everything is up to date then restart your laptop and wait for about 5 minutes before you press the on/off button on your wireless. You can also try removing the wireless card (physically I mean) rebooting, shutting down and replacing the card then rebooting again. If you know anybody that has the same kind of laptop ask if you can try their wireless card to see if it's a fault with that. Sorry I can't help more.

Try the battery removal/re-install approach. remove battery, hold power sw down for 40 seconds with power cord connected; replace battery. Works for me.

Nothing is shown on my Dell Latitude D510 laptop when it is attached to power. No leds, nothing.

1st try a known good AC adapter, see if any change. 2nd, remove all drives, battery, external devices, RAM and wireless cards and see if system powers on and gives memory beep code error. If no change, replace motherboard. If you get beeps, power off, install a RAM module, see if system posts. If it does, add items till you identify the failed component. If no go, replace motherboard. Motherboards are roughly $150 on EBay

My laptop power button lights up,but the volume,mute etc. button l.e.d.'s will not light up and the screen stays picture

If you are getting a power LED and no other indication, you apparently have a NO POST situation. Remove, drives, RAM, Battery and Wireless cards/modem and see if any change. If you get a beep code, install one RAM module, try again. If system posts, then add items one at time till fault is located.
If no change, replace motherboard

My HP Pavilion dv9005us has two issues which I cannot resolve. The wireless device is not even recognized or detected by the computer, and there seems to be an electrical problem where the lighted buttons...

Sorry to here about your DV9005us start up problems.
1st. It would be good to know any other problems you may have had in the past either related or non related to you current problems..

2nd. Has the unit been dropped ?

3rd. The 6000 - 9000 series units are all pretty much the same as fare as board layout.
The top Led's and connected by a small flat ribbon cable. This cable is a 12 pin piece of junk, which you have two in your unit.
Both are located on the bottom left under keyboard. At that connection point the cables push in and are in most cases a solid connection. However, they connect to the Push button - Led Strip directly above the keyboard and at those two connections, HP uses a clamp or push down connection.

For years I have seen the similar problems with the Led's flashing on the Led strip.
Also, you have said the unit at times does not power on, I would be willing to bet, that is why.

One of the 12 pin cables controls the Power startup button, the other feed display information and touch since controls.

Ok, you must decide if you want to take on the repair yourself, or have it done by a technician ? If you interested in doing this repair yourself, you will need to (A) remove any media from the unit along with the battery.

(B) Remove all of the fallowing parts and keep in a static free, dry place, away from your work and tools.

(C) Remove the two plastic covers underneath, covering the memory and Hard Drive.

(D) Remove the Hard Drive and set in safe place. Remove the memory and do the same.
Note... Just to the right above the memory is the CMOS battery (2 pin) Red and Black leads. Disconnect where connector meets the board.

(E) With the unit on its back and the battery compartment at the top, remove the first row of screws (6) set them aside.

(F) Now, in the battery compartment, you will see (3) silver screws, remove them.
Note... You do not have to remove any other screws at this point on the bottom of the unit.
The remaining screws are for the keyboard, which we will leave in place and the DVD drive.

(G) next you will want to flip unit over and firmly with both hands grasp the Led cover or strip and lift up.
Note... This Led panel is connected in (3) places. 1 and 2 are the ribbon connections, the third (3) is your sound connection (4 pin).

(H) Once the Led panel is loose, stop the Led panel should be able to fold over the keyboard, revealing the (3) connection points.
Note... These connection points are very delicate and easy to break. So be carefully.!!

(I) It may be a little easier if you disconnect the (4) pin sound connection. This will give you a little more run and flexibility.

(J) At this pint you can lift the gray plastic tabs a few mm and re-secure the two flat cables.
Note.... These cables are very easy to damage, so handle with care.
You may want to reseat one at a time, remembering these flat cables need to be completely seated.
After you have reseated connections and reinstalled Black (4pin) connector, fit Led panel back. Note. you will here it snap into place. Hold down the power button for 15-30 seconds. This will clear the CMOS.

(H) Flip unit over, re-install the hard drive and (1) piece of memory.
Install the cover for the Hard drive compartment.
(I) re-connect the CMOS battery.
(J) install (3) silver screws in battery compartment. The remainder of the screws can wait until you have finished.
Install battery.
(K) Flip unit over and connect to power source.
Now this time I want you to touch the Led strip. The strip should bring uo the unit in Quick Play, (unless you have deleted it.??
See if the Led's are still blinking ??
The unit should come into the BIOS screen asking you for the time and date.
Note.... If you can stay in this BIOS screen without shouting down, and the Led's are not blinking, you’ve done it...
After setting the date and time, you may want to power down the unit, flip it over and replace removed screws.

If you are smart, you will run over to and download and FLASH your BIOS to current date.
Please make sure the unit is working 99% before updating the BIOS. While flashing the BIOS, Do NOT TURN OFF UNIT.

Reader, please rate this information, weather you agree or disagree, it lets the technician who is typeing this information,(one key at a time) it was worth the effort.

Hope this information find your computer in good to better health..

Latitude d600 will not power up. Battery and charger are good

If the system will not power on with a known good power source, then you need to remove the drives, RAM, modem and Wireless cards, then try to power on with just the AC adapter.

If the system still fails to attempt to POST, then it will need a motherboard. If you get Lock Light LEDs and beeps, then put RAM back in the system, and try to start it again. If still no video or power indications, replace motherboard.
