I have a vistros1500 and the A light is flashing with no display

There are 9 states for LED error codes on this model. The error you're describing indicates that the laptop does not detect any RAM (memory sticks). Since you tried to isolate bad memory stick it looks like your motherboard has a problem and needs to be replaced.

plz try by increacsing the contrast of the screen, if the problem is not solved then you have to take it for servicing.

There is a problem with the battery, contact your manufacturer.

Please rate this reponse.

Remove and re-seat your RAM cards. Remove your battery but leave the power supply attached. Try to start. If this doesn't work, your motherboard has died and needs to be replaced. Not a do-it-yourself job unfortunately.

I had the exact same problem (Vostro 1500), the short story is the computer is dead and I'm looking at replacing the motherboard. Here's the long story: Whenever I got the error message, I'd fiddle with the connection at the back of the computer, and "reset" the power adapter (see below for my reset procedure). That worked for a while until last week--the computer refused to recognize the power adapter, and my little trick wouldn't work. I have no means for charging the battery, so now the whole system is dead in the water. I've determined the problem is not the adapter itself, as it works fine in another similar unit I own. It's definitely the computer's power port or some internal component related to it. Lo and behold, a bit of searching on the internet has revealed that this is a common flaw with Dell Inspiron 1500 series, and Vostro is a close relative of the Inspiron. I'm going out on a limb and assuming it's the "Inspiron Affliction." Anyway, every solution I've found recommends replacing the motherboard, because the power port is integrated with said board. $225-$300 is the going price. I'd just use a dock, but Vostro doesn't accomodate a dock, so that option is out :-/

Dell Power Adapter Reset: If your power adapter has an indicator light, does it refuse to glow when plugged in? To "reset" it, unplug the adapter from the wall and computer, then unplug the cord where it connects to the transformer brick. Plug it back into the brick, then plug it into the wall but not the computer. If the indicator light doesn't glow, then something is wrong with the adapter. But if the light glows, then your adapter is good. The next step is to plug it into the computer, if the indicator light stays on, you should be OK for now (although it will probably fail permanently sometime soon). On the other hand, if the indicator light flashes briefly and goes out, the problem is in the computer -- back up your files while you still have battery power! Either way, if your computer is still in warranty, I recommend extending it another two or three years, if that's an option.

Power save settings or it may have an ambient light sensor that automatically adjusts the screen to "match" the surrounding light. Power settings in the control panel will hold the key.

The flashing CAPs Lock is an indication of a MEMORY error. Try Memory modules one at a time, and see if the system boots with one module or the other. If it does, then replace the faulty module. If system will not post with either module, replace motherboard.

I think that you would have a hardrive issue find out if your laptop uses an ata drive or an sata drive and i would look into getting a new one. if you have any further questions you can email me at [email protected]

You should be able to remove the LCD hingecover and reeseat the video cable. But hte issue may be a damaged cable going thru the hinge assembly which would require a replacement LCD.http://support.dell.com/support/edocs/systems/vos1500/en/sm/display.htm#wp1179838
