Screen seems dead, but comes alive once in a while

ALBa something, it has model number or sub name.'
googling that name,gets me nothing
what you said makes zero sense
try the full story
what does not work,computers have 1000s of ways to fail.
the screen is black. is our only clue.

this i can not understand
i can connect to my laptop and says device? works properly?
what laptop what device, connecting how?


if you turn on the ALBA
and it seems its ALIVE
use a flash light, to see if the LCD screen has data
if yes, the back ligting is dead.
but , what is an ALBA.

i can not tell what any person can fix.
in my shop it is taken apart and we check power to the screen first
if it dead,maybe the battery is toasted.

Try replacing the battery it might just have a dead cell or it just maybe no good

well the screen is dead and the emachine splash is dead
so screen triple dead if BIOS is dead, so we fix that first.
here are the tests in order correct.
and quadro dead, fans dead.
All uSB devices unplugged. DVD tray EMPTY for sure does button eject work if not power is failing. to DVD drive.

1: remove the huge battery first they short and overload the PSU power rails and VRM inside the PC , just remove it.(easy no?)_

2; then use only the AC to DC power pack for power, even for ever.
let me be clear run on AC power only.
3: screen wake up yet? a goal best BIOS screens up.
4: the flashlight test is next to any black screen , pc seems on.
I can hear HDD spin ear to casing of hdd, hummmm
5: still dead screen? out the hdd, remove it and DVD drive both
as those to can short, in fact up to 20 things in a PC can FAIL.
6: the coin cell above 2.9vdc and never below, 3.3vdc new.
CCLF DEAD.
7: strip the PC down more, in you mind focus on modules and device that can short, even to to 1 stick of DDR memory, AC power cord pull do not remove things inside any PC with AC power to wall jack, ever, and big battery is already gone until PC runs right again,.

2009 MADE NEW. CCFL INSIDE !!!!!!!!!!
emachines eMachines W4620 (M622-UK8X)

1. Take off the the power plug
2. take off the battery
3. press and hold the power button for 10-15 seconds


Now try turning it on, if it still doesn't work, check in your manual how to RAM cover, and take the RAMs out (before you do this repeat stpes 1-3). After the ram is out, try turning it on if you hear sirens , that could be at least some indication that your motherboard is alive. if no sirens --- than you got bad news.

So at least you will now if there is a chance if the motherboard is not dead.

A few things to try. First turn on the unit, and after it seems to have booted up (like at a windows login or something), take a flashlight and in a darkened room shine it on the screen. If you can see a picture, it means your backlight is out. Go on ebay or elsewhere online and look for an acer aspire 1690LCi backlight. Then open up your screen and replace it (there should be tutorials online for this). If you don't see an image, your screen maybe be out or have more serious problems (video card, LCD dead, etc.).

possible power supply are motherboard possible bad pin on board

Hello vfedele5, The plug on the unit itself maybe the culprit. Check the voltage during power up, a resistance in the power line may be present. If the unit passes these test you have an internal connection error, bad internal connection, solder connection, ect. Merry Christmas.

try updating the firmware to this

When you close the lid, there is a small pin that engages the case and flips a switch to tell the laptop the case has been closed. The monitor will ALWAYS turn off then, because otherwise, the heat build up would burn the screen! Do not try to defeat this, replacing an LCD screen is usually more expensive than the value of the laptop!

Now, that all being said (and please remember), the situation you have now is (hopefully) just that the laptop tried/succeeded in going into ACPI "suspend" or "hibernate" mode.

1. Remove all cables and 10/100. Remove all USB devices. Just leave the PSU (AC power supply) connected.

2. Press the power button firmly, JUST once. Wait. And I mean WAIT, because some laptops can take 2 minutes or more to come out of suspend/hibernate, if they were very busy at the time it was shut down.

3. If the LCD screen lights up. you are done. But if it does not light up now, then proceed to step 4.

4. Press and HOLD the power button down for 10 seconds. This forces the laptop to shut down completely, even from suspend/hibernation. Some unsaved files may be lost, but tghe laptop goes cold, so you can start ACPI over again.

5. After a few minutes, press the power button again, firmly, just ONCE and for 1 second max. Laptop should start up OK.

6. Once it starts up, go to START MENU/SETTINGS/CONTROL PANEL/POWER SETTINGS and search for the "hibernation" tab. Turn hibernation OFF. your laptop obviously has some problems or lack of responsiveness with hibernation (most do). Use suspend, instead. It is much safer,. faster, and still does a good job of saving HDD and LCD wear. Please let me know how this goes for you, there are other more detailed problems that may be involved here, but I suspect this is most likely.

this will be easer than you think.
first unplug power cord,pull out your battery and test it by pushing the button on the battery. It will be dead. leave it out. plug in power cord, nothing should work. test your power cord. if nothing than test lower on the cord it might be the plug in that plugs into the laptop. what happens is the battery get to low and the lappy goes into a safe mode . you will need a charged battery to get it to boot.
