Power drain would be a better solution in this case.
1.first shut down the comp
2.unplug the charger
3. remove the battery
and after press and hold the power button for 60 seconds without any charger and the battery.After the 60 seconds replug the battery and the charger and turn the computer

My acer laptop does not display but it runs.what is the problem?


Shari,

There are many things we can try to find out why this is. To start, When the computer boots, Do you hear the windows chime? this will indicate the laptop boots. otherwise we could be looking at other hardware.

With the laptop turned on, if you hold a flashlight to the LCD you may be able to see faint images. This would indicate an issue with the LCD or the Inverter located in the laptop and you should have it serviced by a professional to repair such items.

Also while booting the laptop we want to watch all the lights on the laptop. Occasionally when a hardware item fails we identify it with a bios Beep code. In laptops this is a flashing light that will blink either by the AC plug, Right under the LCD, or the front of the laptop.

When we start the laptop does the fan spin up very hard and then slow down again? do we hear a beep shortly after? This indicates what we call "A post" it means your processor, Video, and Ram all passed intitial tests to start your computer. If there is no beep dont panic as not all laptops do this. The fan however, if it does not slow down will indicate a hardware issue. This typically can be CPU, RAM, or Motherbord.
When your computer boots, does the screen stay completely black or does it boot past a splash screen and go to a flashing curser? This could indicate a hard drive issue. Usually repairable unless we hear clicking from somewhere in the device.

The last thing I would suggest trying is if you have a regular computer with a regular monitor, you can plug the monitor into the side of your laptop to see if the screen comes up on it. There may be a keyboard shortcut you have to press and if you let me know what model Acer laptop I may be able to help you with that as well.

Good Luck!

Hi,

I believe blinking lights on the Caps and NumLock means that there is a problem about the Hardware, I've been a Tech Support for HP and those blinking lights are problems for Video Card, CPU, Memory.
It would be better if you call the manufacturer try if they can service your machine.

Hope it helps. =)

Download either a Hiren's Boot CD (version 15.2), or a free version of Parted Magic (either or both on a CD instead of a flash drive ... because flash drives can EASILY be infected by malware and viruses! Set your BIOS so that the machine will not try to boot to the hard drive, but only to the CD. Then access your files via the OS on the CD, and copy whatever you need to copy off to another location.

My Vostro 1500 will not turn on anymore...help please!


Reset/replace the Ram/memory. Sometimes faulty and failing ram can keep a computer from booting up. If you have 2 sticks, take one out and then try to boot, then try with just the other stick. The flashing caps lock icon means a general failure, though it is most commonly associated with the motherboard.
