My granddaughter messed up my desktop Dell inspiron 20 model3052 and I cant get it back to my user screen to log in

SOURCE: Dell D600 LCD issue

What I've found on two laptops I've worked on in the past two years is that in a case like this, there is a little pin near the power button (or on the strip up near the display) that tells the laptop when the monitor is closed.  If that pin gets stuck, the computer will think it's shut all of the time.  The sensor is only active in normal mode of windows with the drivers installed (if it's in safe mode or VGA mode  the sensor does not work until you raise the resolution.  the sensor doesn't work at all if you boot from a knoppix cd.)

You may be able to just flick the pin and get it unstuck, but in some cases you have to remove it all togther.

To remove it, turn the lapotp off. lean the monitor back as far as it can go (don't force it). You then need to carefuly pry up the strip that the power button is on (ussually there is a space you can pry open on the left or right side of the strip depending on the model laptop; be very careful not to break anything).  You can then pop it out with a small knife or tweesers and clip the strip back down.

If you don't feel comfortable doing this, then find someone who is.

I hope this helps someone.

Sounds like a back light problem, power reset it, pull out the battery and ac adapter and then hold the power button for 1 minute, then replace the power cord and battery and start it up, if it doesn't work try calling dell to see if you can get it repaired under warranty if it is out of warranty take it to a shop.

Someone has turned on the BIOS password on you and therefore the PC will not let you boot up unless you enter the correct password. The problem is you cannot turn off the password option unless you know the password. I would start by asking other people who had access to you computer what they set the password to. If nobody comes clean, then you will have to call Dell Tech Support to get them to reset the password for you. They will give you a master BIOS password to override the one set and turn off the option.

I'd suggest first removing your memory modules and reinsert one at a time.

But, I think your operating system is compromised, due to Spyware, etc.

Since your system won't boot in Safe Mode, your only other option is to repair or reinstall your operating system.

Hope this helps.

Restart your laptop and keep tapping F8 key the moment you see something on the screen. You will get a black screen with some options written in white. Select the option Safe mode and then you can create a new user with admin rights. Or else at the windows login screen press and hold ctrl and alt key and tap delete key twice and then it will take you to a login screen. Dont put any password there just hit enter. And you will be able to login with admin rights.
