Dell XPS M140 laptop shuts off after powering on

Press on button for Dell XPS M140 laptop, no color lights on power button, just white. Lock lights flash on, system sounds like booting, hd is spinning, then lock lights go off - click, PC shuts down. No POST, no video at all. Tried reseating hd, RAM, cd-dvd, etc.etc, disconnected all and tried a clean boot, same issue. Green steady light on power adapter, battery removed and tried to power on. This is a friends laptop and she says that was working on cleaning a virus and it just shut off and hasn't rebooted since. Went through Dell step-by-step troubleshooting, that didn't help.

Any ideas would be very much appreciated.

    I apoligize for taking so long to get back on this problem. It turned out that there were several issues. The ZIF Processor needed to be reseated, the heat sink vents were clogged with dust, and the laptop was set to hibernate and power down. I believe your suggestion helped me get to the problem much much quicker. Thank you!

    I have the same laptop that when I turn it on all the green LED's light up and the HD starts to spin and the click the system turns off. It happens wether it runs on battery or adapter. I took computer apart and re-seated cpu and have now noticed that the fan does not turn on when the laptop boots up. I have another laptop of the same model that went bad and tried to replace the cpu fan with it and it doesnt boot up either. I'm stumped.

Most laptops that I have worked on that power off that quickly turned out to be an overheating problem. Is the cooling fan running for the brief period that you can hear the hard drive before it powers off ? If the fan is running another potential resolution might be to remove the processor and apply new thermal paste.

The dell logo flashes then the screen goes blank. The hard drive keep flashing like the laptop is booting up okay it is a xps m140 and has vista home as a o/s


After the logo flashes, press F8, repeatedly, until a white-over-black "boot menu" is displayed. Choose "Safe Mode", to see if this "minimal" version of Windows will startup successfully.

I have a problem with my M140 Dell XPS LCD display. I have a white patch from top to bottom not complete screen but a portion of it. Do I have to replace LCD or inverter


This is most likely cased by your LCD screen being defective.

The inverter will either light the back light or not, it does not have the ability not to filter certain parts of the screen. It could however be that if your seeing wash out and it goes from super bright white to a dimmer bright white the inverter has failed and the bulb is running at full power.

Most likely it is your LCD.

To test your inverter, turn your computer off.

Press and HOLD the FN key while pressing the POWER key.

Once you see booting dell diagnostics, or something similar you can release the FN key. You might have to release the POWER key sooner if the under shuts down.

Dell xps m140 screen goes blank


More like the back light has burned out on the LCD. Not an expensive fix, but time consuming. Almost easier to put in a new LCD (about $60us on Ebay), and is something you can do yourself.

Notebooks usually don't have high res . They trade off the high resulation  for the small size and less power consumption.

No power


Unplug All External Devices Unplug the AC Adapter From the Wall Outlet. Disconnect the AC Adapter From the Laptop Reseated the power cable to the adapter.
Remove the Battery Connect the AC Adapter Directly to a Known Good Outlet, But Not to the Computer Verify That the AC Power Adapter Has a Solid Green or Blue Light.
The AC adapter status light is solid green. The AC adapter status light is solid green.Press the Power Button and Check for POST. Post means if you see the dell logo,remove the battery, plug the ac if still it wont turn on or doesnt have any light,Reseat the Memory if after reseatting the memory still the same problem it might be a bad motherboard.
