Question about PC Laptops

Laptop video failure

I have a Dell Precision M60 laptop. The other day the screen just went blank and the computer crashed. I was able to reboot after a minute or so into setup but the screen started showing grey, blank, vertical lines, then black and white dots and finally nothing at all at which time the computer appeared to have copletely crashed. The screen is fine for it has occasionally worked for a brief period before the line appear. What part could be causing the problem? Any ideas?

    Thanks. Problem is the same with external monitor. If I could identify the specific chip on the Dell Precision M60 MoBo, an electronics technician friend of mine is equipped to heat the part and reset it on the board (if it is a problem of it becoming loose). We tried heating and resetting the chipsets and it worked fine for more than 15 minutes, even booting into windows XP Pro perfectly but then after we reassembled the computer the problem returned. We now do not know if we hit on the broblem or what.

    There are few of these Dell Precision M60 systems here in Colombia so I doubt it unless I can find a cheap one on the internet. Any other tests I should do or parts that could be causing this problem? If I have time I will be disassembling the computer again tomorrow and trying again but I am intrigued because I did get it to work fine once before the reassembly. Was it a fluke? Did I touch something that was loose and then loosen it again when I reassembled? What could it have beeen?

    It is definetely a hardware problem. Do you have any suggestions where else I might post this problem and get prompt assistance like I got from you? Whatever your reply, thank you very much - you have been most helpful.

    it sounds like your display might have gone out on your motherboard. Can you try to hook up an external monitor. And after it reboots try to select display modes Fn + F4?? Or something along those lines. It will be in the Function keys row and have a pic. of two little monitors on it or something similar. If no display on the external monitor then chances are you will have to buy a new system or at least a new motherboard, which is no easy task to repair. But if you let me know the brand of computer you are running I might be able to find a website that could give you some directions

Sounds like you may have "hit the problem" But to me sounds like the chip itself is no good anymore. Any chance of getting a chip off another board and replacing it?

    might want to check the solder leads or contacts(whatever they are called) the little metal things on the bottom of the board to ensure they are not touching anything metal causing them to short or ground out. Also make sure the ribbon to the LCD on the laptop is locked into the plug on the mobo. As for software I'm not sure you could always try loading the drivers again but this definitely sounds like a hardware issue.

    try to figure out what kind of graphics card you have and google it. Then look through the replies and start reading the forums. This is usually how i research anything i need. Other than that you can try to look at the top experts in this category and see if they have any more recommendations

Laptop New LCD Screen Cycling Colors


It's probably the wrong screen, cable ,or inverter; in spite of what the repair shop tells you .
Also, sometimes the cable gets pinched if not installed carefully, or the cable connector may need to be re-seated.
Is your laptop a Dell Precision M60 ? I'll see which screen it's supposed to have.

Dell M60


At the left of your power button, past the word PRECISION, there is a slot for a screwdriver. With the screen fully open, use that slot to remove the power and volume buttons. At the other end of the stip you removed will be the connector that connects the buttons to the motherboard. Reconnect it better.

Blank screen with cycling colours (no BIOS; no POST)


Try running diagnostics. Tap F12 repeatedly on the dell logo till you get the boot device menu. Choose diagnostics. Go through it.

If it doesnt even pull up the diagnostics, you can follow this walkthrough from dell's website.

Dell M60 LCD screen stopped working


Hi,
Based on your troubleshooting, it certainly is the lcd that we are having problems with. It can be the cable or a back light problem. first try to reseat the cable. use this manual to guide you. http://support.dell.com/support/edocs/systems/wsM60/en/UG/index.htm

if it doesnt work, try to call dell. they have a grace period of 5-10 days from expiration date of warranty. if still no luck, call spareparts 800-3573355. purchase the lcd from there and install it yourself using the manual i gave.

hope this helps.

thanks.
