Sound like your screen is going out, it could also be the inverter. Could also be the video card, but not likely. Before you go to changing out any hardware, go into the device manager and un-install the monitor drivers. The hardware wizard should pickup the monitor automatically and reinstall the drivers. Then look for any driver updates at the Dell support site. If that does nothing then it's either the screen or inverter.

Acer Aspire Black Screen

You are describing too different types of problems, difficulty in seeing the screen and now it is gone black. The LCD screen will need to be replaced, I'am hoping the built in display light has failed and not the inverter board because you could end up changing the screen and the inverter board adding to the expence. Go to type make and model of laptop, refine search to screen and inverterboard.

Try hooking it up to an external monitor (or LCD monitor) and see if the same thing happens (first attach a monitor then do a cold start). My suspicion (from the a's you described) is that the motherboard is bad - I call it garbage video. Toshiba dealers will probably charge too much for these replacements. If you're a DIYer or you know a reasonable shop that knows laptops, then eBay would be a good source for replacement boards.

I have a dell inspiron 700m willnot display

Hi There,

The best way to begin the troubleshooting process for your problem is to connect your laptop to an external monitor. If you don't have one at home I hope you can ask a friend to allow your to use theirs for a few minutes.

With the laptop off, and the monitor off, connect your laptop to the external monitor. Next turn on the monitor. Finally, turn on your laptop and on one of the F keys in the row of keys above the regular keyboard letters should be one key that either shows what looks like a little monitor screen/screens or as on most Dells, one key will say CRT on it and it's usually the F8 key.

Hold down the fn key in the lower left hand corner and hit the F key as described above that's assigned to make you switch from the laptop screen to the external monitor.

If the monitor ahows what you'd normally see on your laptop screen, then you know that your laptop screen has worn out and needs to be replaced. If both screens are black then your problem is much more serious and the odds are greatest that your video card/controller on the motherboard has failed. For most laptop repair guys this means replacing the entire motherboard.

I sincerely hope the problem is the first one because it's the least expensive. If not, I'm sorry to be the bearer of bad news, but then you at least know the truth of your situation. Also, a favor? If the worst case scenario, remember I didn't do it (grin) so please don't thrash my reating. I'm a professional laptop repair specialist just trying to lend a hand.

Best of luck to you.

My IBM T40 boots to a black screen with the "z"(light at top to right of power.

Try these steps:

1. Remove battery and unplug AC adapter
2. Press power on button for 30 seconds or so (one min is also too)
3. Attach battery and plug into wall
4. Power "ON" as normal

If you are still getting the "Z" and a black screen then I would have the video card or hard drive looked at and replaced. Start with the video card and then look at the hard drive

Laptop to TV connection problem

When your laptop boots up, Windows treats the second monitor (your TV) as a mirror of the primary monitor (your laptop screen). When Windows loads up and finishes initializing the more advanced features, it goes back to it's default setting of a single primary screen, and the secondary screen is in standby, waiting for you to do something with it. The fastest way to get the TV working would be to find the Function key on your keyboard (normally a purple-ish blue key labeled Fn) and the monitor switch key. The video switch key is normally in the Function key row (F1, F2, F3, etc...) and has the picture of a rectangle or TV-looking shape. Hold the Fn key down and then press the video-switch key once and see what happens. Lenovo laptops normally bring up a little on-screen program that allows you to pick which configuration you want. Good luck!

Stactic looking screen

There are two causes for this problem..

1. Your LCD screen is worn out or has internal lose connections..
2. There is a heavy layer of dust inside your laptop which is to be removed using a soft vacuum cleaner..
there are other rare reasons like the keypad is loose and you might have to refix it by removing and blowing air onto it and fix it back..
