    Yes, I am facing the same problem with My Acer 5002 WLMi.

    When powered on, only the power ON LED comes on, the sreen is completely blank (black).

    I can hear some sound, look like it is from HDD.

    Before the screen became blank, I got a vertical white band in the middle of the screen for 30 seconnds. I recall few weeks back, the acreen had some funny characters blinking in black and white.That problem went away when I re-booted.

    yes...mine is doing exactly the same thing (actually it's not mine - i'm borrowing it from a friend!)
    The laptop turns on fine (power light, battery charge light and fan are on) but nothing on the screen.

    I've tried discharging and recharging the battery, removing everything including hard drive, dvd drive, battery and additional memory but it's just been the same.

It could be a variety of things, did you hear the other parts spinning and whirring as before? Then it could be just the screen or video card. Try hooking it up to a regular monitor and see if it will display there. Other problems could be HD failure, but usually your computer would freeze on startup or your BIOS will tell you that instead of a blank screen. Have you tried contacting the manufacturer for tech support on the issue? It is hard to diagnose blank screens over the net due to the lack of information you can get (ie. error messgaes, etc.....)

If you're getting ANYTHING readable on the screen, the problem is likely not the screen. Dim screens are one thing, and messed-up screens are likely problems with the physical screen. If nothing's showing, it's likely the connection running through the hinge into the screen, which can be a little tricky on laptops, though the whole connection between motherboard and screen is suspect. This is a problem because the problem isn't always immediately visible even upon opening the laptop. You might do so, if you know what you're doing, in order to examine and reconnect everything. But you're likely going to have to pay to have the wiring repaired (and maybe even the screen itself, though that's far less likely).

The monitor might be off, because it's possible on most Laptops that you can turn the monitor on and off.

Check to see if the DC POWER Jack is loose. HOLD the bottom of the jack slightly tilted upward (do not use a lot of force). While holding PRESS the on button. If it comes on and stays on, you problem is the notorius power jack cold solder issue. The jack will have to be repaired. Either by DELL or a qualified expert that has done a number of these. It is not a easy task by any means. A skilled ELECTRONICS TECHNICAN could do it. But not a Computer Technician, because they generally just replace parts and do not do component level repairs

SOURCE: Acer Extensa 5420-5687 laptop won't turn on

Okay, Here's the deal..... I recently had the same problems with my friends' Acer Extensa laptop and here's what I did to fix it. I narrowed the issue down to two culprits 1. Overheating, 2. Defective Motherboard. I have fixed the problem but I takes time, patience and some technical ability which may not be available to some. :( (Swapping out the motherboard MAY fix the problem but if the defect is in the manufacturing process then the problems could return). Here's how I fixed it... While in the process of disassembly I noticed a small electrolytic capacitor that had seemingly broken off and had become wedged between the frame (<ital>very lucky! this gave me the clue I was looking for!</ital>). This made me think that it had broken off the motherboard. I proceeded to disassemble the laptop and found the location of the missing capacitor (there are two located right next to each other on the board) and was able to re solder the capacitor back onto the motherboard (could it be a manufacturing processing defect thats causing these to break loose? ). Mine was broken off due to what looked like bad solder joints. Your capacitors could still be attached but have weak solder connections. Also while i had access to the motherboard, I used the opportunity to clean and re apply the heat sink compound to the CPU and thoroughly clean the fan vents. I then reassembled the laptop and EVERYTHING has been running fine now for the last 3 days. Total time was about 4hrs and it cost NOTHING to repair. GOOD LUCK :)

Remove all of the ram, turn the laptop on if it does not beep you have a bad motherboard. If it beeps replace the memory and remove the hard drive turn on the laptop and see if it posts. If it posts without the hard drive then the hard drive is bad. Otherwise it is probably still a bad motherboard.

Hi friend, this could be due to bad battery. Just remove the battery and connect the power to the laptop and see whether it works. If it works without battery, then replace the battery.

Hi ,
The best possible thing which you can do right now is to check few more things ....As the problem doesnt have much to do on.

Try this::
1>Try to Notebook adapter to a different power outlet.
2.>If still doesnt work you can try to connect an external display us.
(if the external display doesnt work might be other issue but if the display works you have take it to the shop where they can work on this.

Hope This will work.
God bless you.

My fujitsu A3130 screen doesnt turn on. the only thing it does is that the 3 lights in the top right corner turn on and off.

1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad.
6. The motherboard could be defective & needs to be replaced.

My Toshiba laptop will not turn on.

this could be a number of things. the first thing to check would be the lcd inverter. to check this simply hold a flash light up to the screen while it is powered on and see if you can see anything. If not the next thing to check would be RAM. turn off your laptop and remove 1 stick at a time, or replace with a known good stick of RAM. If one stick is bad it will cause your video to not work. If replacing the RAM doesnt work then it is probably your video card which is part of the motherboard

HP Pavillion dv9005us screen stays dark

Lets start with the power, make sure it is charging by looking at the ring on the side that lights up when the power cable is plugged in. If this is on, then make sure the light on the front of the laptop is on. If it is charging and it is detecing power(2 lights will be lit) then you are okay with power. If the lights are not turning on, then it might be your charger. This is rare, but its worth a try. Get your hands on another identical one. Make sure the Watts line up or else you might blow something out. If it is not your charger, then it is probably an internal part such as the power plug or the motherboard. In either case, unless you really know what you are doing, then you would simply need to replace these. Before you order a new one online, keep reading.

[skip this part if your power is not working]
Pull out one stick of RAM, then try to start up. If this doesnt work, then try the other stick(put the first one back in). If that doesnt work, then try the hard drive. If this doesnt work, then try the wireless card an any other attachable devices(that connect directly to the motherboard). If this does not work, then the problem is in your motherboard and you will probably need to replace it.

[If your power is not working and/or it looks like you need a new motherboard, read this]

Be sure to contact HP first, they are doing a recall or as they call it a "service enhancement" to some of their malfunctioning laptops that are having motherboard issues. You might want to research what the service enhancement covers first. This will be important when dealing with the representative. Also make sure you try a lot of things with fixing it, even if it seems rediculous such as cleaning out the fan. The more it looks like you tried to fix it, the more likely they are to service your laptop under the 'service enhancement'.

Here is more info on the service enhancement. Be sure to read as much of it as possible. Sometimes the representative on the phone will try to say it isnt covered beucase it doesnt match the symptoms exactly. Try to show them as much as possible that it does fall under one of the defects listed and they will most likely fix it. This is a one time shot though, be sure you dont screw it up!

Hi, Try running you laptop with the battery and the AC adapter. If by plugging in your adapter there is no light indicator likewise or no powering up, then presumably there is a problem with the power supply circuitry in the motherboard. Normally the laptop should work with just the adapter, just the battery or both the battery and the adapter. If it will not perhaps your best bet is to seek professional repair service since this would require opening the motherboard. In most instances, this involves an smc fusible link, regulator transistors or even just cold solder or loose connections. Hope this be of some help/idea. post back how things turned up or should you need further information. Good luck and kind regards.
