Thanks for ur healp,i have presario v with no backlights i replaced the inverter and the display screen and still no backlights could u tell me what is the problem? The whole back is loose except for the area around one corner of the fan which seems to be held with a screw from above possibly under the key board? The company I used repaired my laptop, but the repair only lasted for 7 days. Thank you for this post. The DC jack soldered to this board.

I googled for the problem and eventually found an answer. Would you have any idea as to how much it would cost to repair this laptop. I am having the identical problem with the Compaq presario F as described by Josh and Jamal. Too bad, I was really looking forward to f557uss I hope others are as appreciative as I, and I would like to encourage them to make donations as well.

You can try reinstalling the sound driver. Warren, Thank you for your generous donation.

My F will not power on. I can plug it into a regular monitor and can see everything fine. Have reseated the LCD connection to motherboard several times with no results. Remove three screws securing the memory cover and two screws securing the hard drive cover.


What is going on now? Then d557us goes quiet, remains that way with the blue light still on for about 10 seconds, then powers down on its own.

Distro Ubuntu Development Release. Try removing memory modules one by one and test the laptop with each module separately. Is there something I can do to fix this? AC adapter is good, I tried with onother one but with same result.

And the screen no longer turns on. Now reboot the laptop and let it re-detect the drive and install the driver. I got this laptop a few years ago and I tried installing ubuntu 7. I have adjusted the brightness so know that will not help it.

The onboard WiFi quit working. May 17th, 3.

I would like to check the battery voltage but I am not sure which of the 6 cmopaq knife blade connections is which? If you still experience the same problem with newly installed Windows, this is the motherboard problem. As mentioned in the text, a couple of extra screws on this model but pretty obvious.

When i put the old ones back in it boots up like normal. I removed the screw for the dvd rw and it just wont slide out of the computer, not sure if have to take apart the whole assembly to remove the dvd drive, i unscrewed it, but still it wont come out. Take a look at this service manual for Compaq Presario F series notebooks. I have a compac presario F lap top. On the home page where the volume is it shows the volume and it just has a red x on it.

Also when starting my computer the v557us is black and the power button flashes, and to start the computer I have to unplug it and take the battery out, I think the problems might be corrilated some how? I hope this repair will last for some time. What could I wrong during assembly? I have removed all the screws around but im pgesario to pry it open for fear im prying in the wrong spot and will break it.
