I have an acer aspire 5100 and here recently the screen has started to flicker and flash and the laptop will not charge and cannot be removed from the ac charger
Re: I have an acer aspire 5100 and here recently the
Could be a bad battery and/or charger/AC Adaptor/DC Connector. Try to isolate the problem by removing the battery and then plugging the laptop charger in and starting the pc up. It should boot on the AC adapter alone. If it won't boot on the AC adaptor or it flickers and flashes while on the AC adaptor, I would first suspect the AC adaptor or the DC connector on the laptop (try wiggling the power plug at the PC to try and check the connector). If it behaves while on the AC adaptor without the battery present, I would suspect the battery. Either way, you may have to replace something.
This is a sample of what you can try to do to diagnose a non-starting computer, If these don’t work, realize that most likely a system board (motherboard) has failed or the actual power trim strip above the keyboard has failed.
Unplug the computer, then take the battery out, push the power button and hold it for about 30 seconds. Plug the system back in (leave battery out) and push the power button. If it starts, Great! If not unplug go to the next step.
You should still have the battery out and the power unplugged. Now turn the laptop over. Take off all the covers and pull out the hard drive and ram and wireless card. Find the screw that has a symbol kind of like this � its the CD rom drive screw. Now pull the drive out. Pick one stick of ram and put it back in the computer. Flip it over open it plug it in and hit the power button. If it does not fire up then unplug it and switch the ram. Plug it back in and hit the power button again. If it doesn't start up, unplug the computer and go to the last step.
Pull the memory out and find the screws that hold the keyboard on. There are symbols in the plastic there should be 2 screws holding it in. Now in the battery compartment, there are several screw at the back edge of the computer take them out and also the ones in the battery in the center strip. Some are silver and some are black. Once you have the screws out of the battery area flip the computer over and open the lid. The strip just below the LCD with the power button and controls will now be able to be lifted up. You will probably have to lightly get an edge started before it will come up. There should be several little cables hooked to it. Flip the control panel over and look for some screws holding the keyboard in. I think there's 2. Lift up the keyboard. Making sure there's nothing touching anything important and then plug the computer in. Carefully hit the power button and see if the computer tries to start. If it does try it will probably beep at you. Unplug it and put a stick of ram in it. Plug it in and try to start it again. If not, unplug the computer and Go to the next step.
Carefully put the keyboard and control strip in place. Flip the computer over and loosen all the screws that hold the computer together. Flip the computer over again and pull the keyboard and control strip up again. Flex the inner aluminum plate that was under the keyboard lightly. Plug in the computer and then hit the power button. If it tries to start, Great! put it together again in the reverse process.
If it does not, there are 2 possible things I would suspect the Control strip or the mainboard. If you don't get the computer to start back up please put it back together so you remember where all the screws go. Even if you plan to get another mainboard put it back together.

Generally Acer recovery start with ALT+F10.
As soon as you restart the computer, hold down the Alt key using your left hand and start tapping F10 key using your right hand. Acer recovery would be started. Now, follow the on screen instructions.
Most likely, the problem is NOT with the motherboard, but with the screen itself. It could be either the flourescent bulb or the inverter board. Cost to repair should run about $175 or maybe less, depending on which of the two it is.
If you can't get it repaired locally, contact me for information about shipping it to me for repair.
Hi,
if you have screen Flicker, this could be several Things. Faulty or Failing Inverter Board, Or tft screen tube failing ( usually determined by occasional Pink Screen At Startup ) try to use an external Monitor. if it,s fine on an external. this will eliminate motherboard or graphics chip fault.
My Acer aspire 3003 keyboard and touchpad both started to lock up recently. I use it with the battery removed, it avoids the problem. The battery wasn't holding much charge anyway.
