I f this is a laptop, what usually happens is that the connector on the system board is loose. And it will need service. Luckily it is in warranty.To keep this from happening again, pull the ac adapter straight in and put it staright in without wiggling it in/out.

Desktop do not have ac adapters. If it is a desktop, your power supply probably needs replacing.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Winbook laptop wont power up, could it be a security thing


First you state Desktop then Laptop ?
Take the battery out, plug in the charger and see if the laptop works.
If it works, the battery may be the problem.

Check the AC Adapter
Check to make sure the adapter is plugged securely into the wall outlet, connected firmly to the adapter box and to the back of your laptop.

Most AC adapters have a little light in themon that rectangular box in the middle of the cord that lights up when it's getting electricity.

If that light isn't on, try a different outlet.

Check your fuse or circuit breaker box and plug a different device into that outlet to make sure there is power to it.

If it still does not light up, your adapter could need replacing.

Also check the adapter box for signs of warmth, as it will generate heat when it's plugged in. No heat means no power.

Remove the Battery Sometimes it's as simple as a seated battery.

Remove the battery entirely and clean out any dust, lint or hair that may be clogging the connectors and preventing a proper connection.

Reseat the battery securely and make sure the little locking pins that hold your battery in place are securely fastened and there is no movement.

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.


Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards


Check all power and data leads from motherboard to hard drive and all of your cd/dvd drives make sure connections are secure dust free and not faulty

computers need all power and data to travel through every working device and to finish its cycle
so any faulty lead will end in computer error or shutdown / fail to boot or to reboot on a cycle

make sure your computers RAM modules are securely seated with no dust in the sockets also the Cmos battery has charge and seated with no dust in the sockets.

some Motherboards Cmos batteries are soldered in.

Compac d-530 won't start red light under power button flashing


Take out the battery and only hook up the AC Adapter. Try turning on your laptop and if you still only get a flashing power button then try another AC Adapter. If the same thing happens then that means the motherboard is bad and would need to be replaced.

After connecting the AC adapter to a wall outlet and to the computer press the power button the right side of the inspiron. The button itself should then lite up white if the power adapter is good.

There are 3 things to consider in order for you to determine a No Power Issue

2. Disconnect all non essential cables (external hard drive, usb memory key, printer...etc.)just connect the AC Adapter

3. Take out the Battery....Usually there is a battery indicator that you can push at the back of the battery

4. By Now the battery power indicator should be full since it was never taken out

5. If still theres no light on the battery.... replace battery

6. Turn the laptop on without the battery

7. If the computer still did not turned on check the AC Adapter if there is light coming out

8. If there's no light that comes out from the AC Adapter. Reseat the cable from the AC Adapter to the Cord

If a PC suddenly fails to boot properly, you should perform a hard reset as the first action. Performing the hard reset will correct many problems. If the computer still does not start properly, select your symptom from the list below to guide you to the recommended corrective actions.
  1. Disconnect all peripheral devices and remove all USB devices and SD media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
  3. Reconnect the AC power adapter (but do not insert the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a fan or other moving parts turning.
  4. If the computer does not start, the LED lights do not glow, and the display is black, you can perform one or more of the following actions to resolve the no power issue.
    • Verify the computer is receiving power from the AC adapter . Verify that the AC adapter is not damaged and is connected correctly to a working wall outlet plug. Verify AC power is connected to the system board by examining the AC adapter, wiring, and pin connection for damage. The keyboard LEDs will glow when AC power is connected to the system board. Damaged components, like the AC adapter or the pin in the power connector, may require an HP-certified repair.
    • Use a different AC power adapter . If you have access to a different AC adapter or power pack that is designed for the computer, connect it to the notebook and try to start the computer. If you own or have access to more than one notebook, verify that you are using the adapter which belongs to the notebook. CAUTION: Using a power adapter that does not meet the power requirements or has the wrong type of connector may damage the computer. On newer notebook models, connecting the wrong adapter to the notebook may cause the power LED lights to blink but not power the computer.
    • Remove the battery and boot on AC power only . A discharged or defective battery may prevent the AC adapter from supplying enough power to start the computer. To verify that power from the AC adapter is available for PC; remove the battery, connect AC power adapter, and press power button. If available, try using a different AC adapter, that is rated for the PC, and repeat this test.
    • Remove the AC adapter and boot on battery power only . A defective AC adapter may not charge the battery and prevent the computer from booting on battery power only. To verify battery power available for the PC; connect AC power adapter, allow battery to charge for 30 minutes or more, disconnect the power adapter and press power button. If available, try using a fully charged battery, of the same type, from another computer and repeat this test.
      • If LEDS do not glow and the fan or hard drive do not spin, battery may need to be replaced.
      • If tests of both the battery and the AC adapter fail, there may be a problem with system board requiring service by HP.
      • If LEDs glow and PC boots, the AC adapter may need to be replaced.
      • If LEDs glow, but PC does not boot go to LEDs glow, fan is heard, but display is black or blank section.

Acer extensa 4620Z laptop computer will not re-charge battery. The cord going to the outlet has power...green light...but no lights are on lap top and it is securely pluged into lap top. - When I...


It could be one of three things. It could be a bad battery, a bad ac adapter, or the recharging circuitry could be bad. I would try pulling the battery out, and see if the laptop will startup and run strictly off of the ac adapter. If that does not work, you have a bad ac adapter. If that works, and the battery has any charge left, try running it strictly on the battery. If it doesnt work, you have a bad battery. If it does work, the circuitry is bad and you will probably need new motherboard. One other thing you can check is where the ac adapter and battery plug into the laptop, and make sure there is no corrosion that could be causing a short.

Toshiba A-135 Notebook only works with a charged battery but will not work with the AC Adapter. Is the system port bad?


It could be that the DC jack (what you plug the AC adapter in to) has become loose from the motherboard, or it could be the adapter itself. Plug the adapter into the computer, and -gently- move the cord, just a bit. Does the end in the computer move around a little? If so, you'll want to get it looked at.

If the problem is with the adapter itself, you'll need a replacement. I suggest calling up Toshiba and see about getting a replacement adapter. If the computer is less than a year old and falls under Manufacturer's warranty, any parts that you may need should be covered.
