There will be power plan settings in the control panel... you'll have to modify it to have bright backlight even while working with battery...

Acer TimelineX 3820TG Will Not Power On


make this test and fix it. God bless you
Check your laptop's AC adapter. Ensure the laptop's AC adapter is snugly plugged into the port on the back of the . Also, check its connection into either the wall socket or the surge protector, depending on your setup. Make sure the AC adapter is securely in one of these outlets and not loose. Also, if the adapter is plugged directly into the wall, try another outlet. Your existing outlet may be blown.

Check your monitor brightness settings. Sometimes these settings get accidentally turned all the way down, which results in what appears to be a dead laptop battery or malfunctioning power supply, but is really just a simple fix. Your laptop has dedicated brightness keys at the top of the keyboard, directly above the numeric keys. Adjust the brightness settings here.


    3 Look at the battery indicator light if your laptop appears to be out of battery or suffering a power failure. If it is not flashing or indicating a power problem, your laptop's "LCD closed switch" may be malfunctioning. This switch acts as a sensor which normally judges whether your laptop is open or closed. Sometimes this switch gets stuck in the "closed" position, resulting in the laptop believing it is shut and thus the monitor's back-light staying off. This switch is located right beside either the left or right hinge at the bottom of your laptop's display . Tap this switch multiple times with your finger to attempt to free it up and get it out of the closed position.

    Consider whether your laptop's battery has completely died and needs to be replaced. Average laptop batteries last for approximately 1000 charges, after which point they either gradual deteriorate and have trouble holding a charge, or simply fail altogether.
    Eventually your laptop's battery will have to replaced, and if none of the other troubleshooting steps yielded results this is likely the source of your perceived power supply problems. Flip over your laptop and locate the horizontal outline of the battery, which will be at the top center of the bottom of your computer.

    Notice the battery release mechanism on the bottom of your laptop, which should be directly below the horizontal outline of the battery. Slide this release mechanism to the left to disengage the battery and gently pop it out. The laptop's power supply may now be replaced.

    Screen on laptop goes on and off


    Check or sub the power supply to make sure it is working, because this looks like power supply problem, if battery has sufficient charge unplug the power adapter from the laptop to see if it will run. Hook a spare monitor to the video output usually on the back, if picture okay! the inverter board below the LCD may be the issue or the backlight behind the display.

    Display is dark


    May be the backlight behind the screen is bad or the inverter power supply module that makes the backlight work. A good way to see if it is not the computer would be to obtain a monitor cable that you can plug into the monitor port on the laptop and then into a regular monitor. If you get a picture then you will need to determine what has failed in the laptop...if you do not get a picture on the external monitor, then there is a problem with the laptop itself.

    My laptop acer extensa 4420 5239 will not power on.The battery light goes green if i charged it fine. It seems that the switch is having a problem or might be the power supply. how would i know?. please...


    Probably there is a problem with your battery charger or power supply. It might not charging your battery. The only reason why the laptop would not power on if there is no power supply coming in, either from a battery or a direct connection from the power supply. You can check your battery charger or power supply using a multimeter. Check if there is a voltage reading coming from your charger.

    ACER ASPIRE HAS NO DISPLAY


    Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
    The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.
