Okay, the driver for the camera (hal.dll) needs to be reinstalled.

Do the following:

Press the windows key and R
Type in command
In the command prompt that comes up:
Type in cd C:\Windows\System32\
Type in taskkill /f /im "hal.dll"
Type in del hal.dll
Then restart your computer

What taskkill does is kill the camera applications that is using the driver so you can delete it. After your system restarts, Windows will automatically reinstall the camera driver, and the problem will be fixed!

I have the Dell 1525. The screen is black with only the cursor appearing. Please advise


Check to see if you have the machine switched out to a stand alone monitor. This is a feature on many lap tops that lets you re-direct the signal out to a larger monitor, or if your monitor fails you can display the computer info on another screen. This feature is engaged by holding down the Fn key and tapping teither the F4, or F6 key on many lap tops. This feature can be toggled by both displaying at the same time or switched to the stand alone or the Lap top.

The other cause is that the machine has malfunctioned usually because of the CPU failure and there is nothing to boot the machine up.

How to clean the LCD screen of lap top ?


you could use a cleaner from Kensington (http://www.kensington.com/html/1081.html)
to clear LCDs and it works great. It comes in a little spray bottle, and I use these neat little 3M 'electronics' microfiber cloths to buff off the spray. Works like a charm.

The problem isnt the router


From a machine wired to the router, open a command prompt and type ipconfig /all

Do the same on the wirelessly connected laptop. Make sure the dns servers on the laptop match the desktop. You may have to add the dns statically on the wireless connection. Let me know if that works.

Please help me agian


So, if your motherboard is turning on and the fan comes on than for now you can check to see if your back light turns on for your lcd panel by going to a dark place and turn ont he laptop there. Than check if you see a faint light that stays on or a flicker. If you see a faint light or the display is dim than it is the inverter on the lcd panel otherwise you may need to replace the video card which can be integrated onto the motherboard and may require a new motherboard. All depends on the model you have.

Dell Lap Top


Hi Robert,

You probably have two choices..one of them is obviously to if it can defy gravity on top of a tall building. The other is to press function and the up arrow to see if you can max out the brightness. You should also try to increase the light within windows control pannels or right mouse click the desktop go properties then to the display options to increase the gamma or lighting.

Another option is to see if its worth getting a new screen as cheaper alternative to replacing the whole computer. You may only want this if you are happy with speed of your laptop right now.

good luck
