    OK--what happened last time you used it? Did it work? Did it shut down properly? Can you start in safe mode?

The laptop lenovo z560 does not switch on. With battery it shows 2 short flashes of battery charge idicator, an one long (about 10 sec) and than nothing is happening. Withou battery nothing happens after...


Hi smialkovskyi,

With this specific concern that you do have, unable to turn on your Lenovo Z560, there 3 components that need to be checked. Your battery, the AC adapter (charger) and as well as the DC In port.

1.Based on what you have said, with the battery alone you have noticed that it's led indicator will show however still can't turn on system. Battery seems to be in good condition however no enough charge to turn on the system.

2. For your AC adapter, when you're using it without the battery nothing happens. To check if this is defective try using another AC adapter that is compatible to your unit. If your computer turned on using another AC adapter then your charger needs replacement. (You may also try using your charger to other unit where it is compatible, just to test).

3. However, if after doing the previous instruction and still system won't turn on then it could be the DC In port which is defective. This port is built in to *********** board.

After doing all these you need to contact Lenovo. They might be replacing your charger or *********** board if system is under warranty.

Hope this helps.

Thank you for using Fixya.

When i turn on my acer aspire one d2501821 notebook it freezes on the windows screen


Try doing a system restore and it that doesn't work, try doing a system recovery.
For doing system restore, power on the netbook and keep tapping F8.
This will take u in to the Windows advanced options.
Try safemode.
While getting in to safemode, it will ask u whether u want to use system restore.
Start system restore and select a date in which the computer was working fine.

To do recovery, power on the netbook and keep tapping Alt+F10.
That will take u in to the recovery mode.
Select complete system recovery.
This process will take around 30 to 45 min and make sure u plug in the AC adapter.

Panasonic DMC-TZ5 will not turn on


I had a similar experience, both with my original TZ5 and the replacement TZ5 Panasonic sent me. I was mystified at first, but now I think it's the AC adapter I was using. With the replacement camera, absolutely nothing happened between taking pictures of my new house and plugging in the camera to export the photos. The back of the camera near the AC input got really hot and my surge protector shut off. The camera won't turn on. I don't know about warranties, but if you think that's the problem and were using a Panasonic AC adapter, you should check. My (non-Panasonic) adapter worked ok the first time or two I used it.

Laptop not working


Hi,

Disconnect the battery and the AC adapter from the computer.. Hold down the power button for 2 mins. Now connect the AC adapter only..

If it was an issue with the static electricity then it should fix it.

Else try changing the wall outlet and chk if the connections are fine.

If the brick on\f the ac adapter does not get warm then probable the adapter has gone bad and need to be replaced.

If the it still does not work then you can also try reseating the ram and the hard drive.

If all the above does not work then probable the power module on the nb has gone bad and need to be repaired.

Regards,
Anup

Acer laptop shut of during power outage .


From the Acer website:

Power Issues or Will not Boot
Solution
If the notebook does not power on:

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a ‘power reset' of the notebook.
  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.
  3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
  4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
Also, depending on whether your power went down "clean" (quick and stayed off), or went down and quickly came back on and off many times. Or when it came back on "clean" (came back on quick and stayed on), or it came on then off many times, your power supply may have been damaged from the power surges Are you having any problems with any other appliances?

Battery back needs to be connected to the DVD player when charging. connect the batter pack to player. Run the DC/out from the battery pack to the DC/in in the player. plug the charger into the wall.

if that does not work, you have a bad battery
