I have an Acer Aspire M5201 base unit which i am currently having problems powering up. It was fine last night then turning it on this morning it started making lots of noises from the hard drive and i wasnt getting a picture on my monitor. I turned it off and back on to instead get an extended beep noise instead of the usual quick beep and still no picture on the screen. I have tried different power leads, different monitors, different plug sockets. As a last result i am currently waiting on an Acer engineer to arrange a pickup for repair but i am fairly computer literate and if there is anything i can do to fix this without repairs and call centers then it would be most appreciated if anybody had any advice.

Re: Acer power up problem and no picture on screen
Removethe video car and dimm memory and any other plugged in cards
leave the monitor unattached.
start the machine
if it beeps exactly as u said, the motherboard is faulty and must be replaced.
If it doesnt, or gives out a different beep pattern, turn it off, add the memory dimms ack, switch on again.
If it beeps continuously your memory is bad and you may just be able to go buy some replacements. If you have never removed/installed dimms be careful they only fit in one way around.
If the beep is absent/different to the original problem beep, turn off the macchine again and add the video card - do not attach the monitor. reboot and listen again If u have recreated the original beep that it failed on, its the video card.
This is the standard diagnostic process and can be repeated with the addition of each accessory, monitor, keyboard etc. until you find the culprit. Failed hard disks/CD's/DVD/Floppy will not give you this beep error usually. It is most likely faulty memory chips. If youo have really good manuals that came with the machine, you can look up the beep code to identify the problem as they are like morse code...the beep pattern tells u the fault.
Hope u can resolve it yourself and save some cash!

unfortunatly there are three pieces involved in the dimming of the screen. 1) the lcd (you tried that) 2) the inverter (you also tried that) and 3) the motherboard. I had the same thing happen with my daughter's acer. I bought her a new computer and sold the laptop for parts.
Motherboard replacement on these are a pain.
Sorry for the bad news ... Good luck
My acer Aspire 7520 sat untouch for almost 2 years. I would start it and it would continually cycle on and off. I read a fix and it worked. Here it is.
Put in the battery and press start. Let it continue to cycle on and off and forget about it. When Mine got down to less that 10 minutes of battery life. the damn thing came on I logged in and have had no problem since. It is not a other board problem it is a power supply problem. I am not a computer tech but I know enough about electrical current (as a home builder) and it noever made any sense. something inside the power system needed to be reset and the computer went from one power crisis( not powering up is a failsafe against surge in current) and running out of power seemed to trigger the power unit back to normal. Good Luck! Dave
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.).
Will the unit work without the battery? The new Lithium Ion batteries can be overcharged and then cause all kinds of strange problems. Take the battery to a reputable electronics shop or Batteries Plus and have them run a voltage and current test. The current test being the most revealing. If either of these is higher than the level printed on the battery, dispose of it. Also, check ACER's web site for battery problems. All the computer manufacturers have had battery problems.
If you get a post screen with Acer written on it at startup, and the screen turns off when loading the system (Windows or Linux), then you need to reinstall the system using an external USB cd unit and the recovery disk that was provided with your Acer.
If instead the display has no screen at all , try connecting an external monitor to test the laptop.
If you get picture on external monitor, then the Aspire One has a faulty LCD ribbon cable or a faulty LCD display or inverter.
If you get no picture on external screen , then you have a faulty motherboard, possibly faulty video chipset on motherboard.
In any case check your Acer One warranty, all the faults listed are covered by Acer warranty for one year. Contact Acer at the number listed on documentation to have the computer repaired.
I had a similar problem, but I got a picture before it broke up and went off. The screen was backlit, but no video (screen was receiving some power).
The LCD needs a very stable voltage to work, this is provided through the LCD connector ribbon. In my case the ribbon was damaged and replaced it.
I have had no problem since.
I discovered this through trial and error; I first changed my transformer power supply and then the video inverter card.
