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.

      • 5
    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.

    Pavillion zv5000 won't boot

    Hello.The most common reasons for power issues are the battery, power jack and power adapter/cord.Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.If no change, the power adapter is probably faulty and needs replacement.Hope this helps.

    Dell Vostro Battery charging problems

    Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then -The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty.Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced.If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard.This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

    Acer Aspire 5536 only gives black screen when i connect power supply

    • Nothing is more annoying than a monitor that refuses to turn on. Make sure your Acer monitor is plugged in to a functioning outlet. If it's plugged into a power strip, try replacing it with a new one or moving the plug to a different outlet. Ensure that both ends of the power cable are plugged in firmly and securely, and that the connection to the monitor is not loose.
    Cable Issues
    • Your Acer LCD monitor will usually accept DVI and VGA inputs. If you have an older computer, a VGA cable should work fine. If it doesn't have a VGA port, you'll need to obtain an inexpensive DVI to VGA adapter at your local computer store. A DVI cable, however, is compatible with most modern computers and offers superior picture quality over VGA. Make sure you're using the cable that's compatible with your system, and that you have the proper conversion adapter, if necessary.

    Power adapter issues...

    If you can jiggle the the power cord right at where it plugs into the computer and sometimes the green light comes on, that means your DC Power Jack is bad. There was probably nothing wrong with your other power cord. When the DC Power Jack is bad the laptop will not power on if the battery is drained of all of it's power because the Power Cord can't charge the battery.

    Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

    The most common reasons for power issues are the battery, power jack and power adapter/cord.

    Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty. Since you swapped the battery, the battery is is probably OK.

    If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

    The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.

    If no change, the power adapter is probably faulty and needs replacement. Try your cousin's power adapter to see if the problem goes away. If the problem goes away, replace your power adapter.

    Hope this helps.

    There could be a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
    If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.

    Power unplugs on laptop, black screen, computer still running

    It's a common trouble for the power cord from the adapter to break inside the insulation near the plug. This is because of frequent flexing of the cord near the plug. When this happens you'll see the power light on the computer go out, and wiggling the cord sometimes gets it going again. Without the power input, the battery doesn't charge and the laptop won't stay running.

    This sounds like what's happening to your computer, and should be fixed by replacing the adapter. Generic replacements are available at reasonable prices from online vendors and at Radio Shack and big computer retailers. It's also possible to repair the adapter by cutting the cord back and soldering on a new plug if you or someone you know has the tools and skills.

    Please take a moment to rate this solution if it's what you needed. Thanks for asking here!

    You need an 18 to 20 volt AC adapter for this Laptop.
    You can get them on ebay for really cheap,
    If in doubt buy a universal adapter which will fit almost any laptop or lcd monitor.
