Most likely the laptop presentation mode is on. press the Fn key and the F5 key together (maybe several times) to take it out of that mode.

Power drain would be a better solution in this case.
1.first shut down the comp
2.unplug the charger
3. remove the battery
and after press and hold the power button for 60 seconds without any charger and the battery.After the 60 seconds replug the battery and the charger and turn the computer

remove all attached devices like printers or flash drives. remove battery and power on using ac adapter only. if it still wont work, try another good ac adapter. make sure ac adapter light is on. if it still shows the power light on and nothing else, replace motherboard.

Dell latitude d620 once i turn on power the power and bluetooth light comes on while the keyboard status lights flash screen stays blank and after about five seconds turns itself off ?


Is the laptop really turning itself off, or is the display just not doing anything?

It sounds like it could be a problem with the nVidia GPU used on the D620.

Dell has extended the warranty on the nVidia GPUs by 1 year. Call Dell and describe the problem.

Laptop screen only starts up 1/4th of the time


Sounds like you have a lot of spyware and malware. Anti-spyware software (such as SpyBot) and antimalware software 9such as Malwarebytes) may not ultimately help, but it's worth a try. I really think that you will need to completely reinstall Windows. Use the CD that came with your system, as it has all your drivers. Let us know if you need help to reinstall. Good luck.

First,If you are running windows vista,This can be due to an update that has your video driver and windows video driver running at the same time.

Hardware would be the invertor board is bad.

Ttry to start with F8 and choose start in vga mode,If this allows you to start normally,go to the device manager and update the video drivers

A few of the keys on my hp pavilion dv6000 came off today- I reattached them and now my computer screen is blank when I turn it on. The power light is on and you can hear it running but nothing on...


try pressing the function or fn keydown and hold it down then press the the f key that turns off and on the display.Do the key that came off feel the same as the other keys when you push them.it could be that the keyboard is damaged and some keys may not be working as in the monitor key.

R52 laptop screen stays blank


Try removing the battery and starting up just on power supply. May be a bad battery. If that doesn't work let me know.
