Question about Acer Aspire 5500 5570-2609 Laptop
My Acer Aspire 5570 got problem. Power can turn on but no display. i dont think it LCD problem coz same problem when i connect with the another monitor. need some solution.
SOURCE: acer aspire 5570 no power
Try turning it on with the battery but without power cord connected, if it turns ON.. then it looks like ur power section on the mother board has problems and u need to take it to the service centre. Also make sure your getting the desired output in the power cable.

Acer Aspire One BIOS Recovery
The AA1 has a built-in BIOS recovery routine, making it possible to
flash the BIOS even if the system doesn't boot anymore. It's only meant
for emergencies and may void your warranty, so use at your own risk.
Follow every step carefully!
First format an USB stick with FAT.
Download the latest BIOS, and put both FLASHIT.EXE and the BIOS file in the root directory of the stick. Rename the BIOS file to ZG5IA32.FD, that's important. Do not remove the USB stick.
Turn the AA1 off, make sure both battery and AC adapter are connected. Press Fn+Esc, keep it pressed and press the power button to turn the AA1 on. Release Fn+Esc after a few seconds, the power button will be blinking. Press the power button once. The AA1 will now initiate the BIOS flash, do not interrupt it under any circumstances. After a while the power button will stop blinking, and the AA1 will reboot shortly after. Wait patiently.
The BIOS has been flashed and all settings reset to default.
If for some reason you made a mistake during the procedure and it doesn't reboot by itself wait 5 minutes before turning it off, just to be safe that it isn't still flashing the BIOS.
Download WIN98BOOT.ZIP and HPUSBFORMATTER from the internet normal bootable like a diskette won't work with a usb stick
I had mine 2 months it's a common problem with the notebook.
The onely thing that you have to do is download these programs with someone with a internet connection.

You could have a faulty inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

It really sounds like you have a short in the ac adapter. Laptops dim the backlight on the screen when on battery power and go full brightness when on AC. I think your adapter is going on and off. When it is on the screen is on full and when it goes off the screen dims down a bit. You could have a bad adapter, most likely, or a bad charging jack in your laptop. Check the adapter first, just use a multimeter set to voltage. Read lead goes to the center pin and black lead goes to the outside metal contact, you should get a reading of 18 to about 26 volts. Move the wire around near the plug that you are holding and keep checking the readout. I think you will find the voltage dropping as you move the wire.
I hope this helps, If so please rate my solution.
