Samsung wp170 I cannot get the unit to power on, it seem to be fully charged quickly and when I try to power it up by holding the button for 8 secs nothing happens.

first go to a mobile shop ask hif it it is the problem of battry or some hardware problem inside the tab and also check the charger weather it works or not

Seems to be a common problem.
You are on the right track with holding down power button.

1. Hold down for 20 secs, Wait 5secs, hold down for up to 10 secs, it may turn on before then.

2. Does the screen have a dim glow, even though there is nothing on it?
Let it discharge itself so the glow is gone, may take some hours.
Plug it into charge for at least 30 mins.
Try to turn it on.

My grandson forgot his password for his Nextbook Tablet, how can I unlock the screen to rest his password.

to manually discharge the battery, just consume the remanining battery power on your laptop. Once your battery is empty, press and hold the power button for 8 secs to discharge the battery fully. Wait for 2 hours then charge again your laptop....

If your Samsung GT-P1000 Galaxy TAB is frozen and unresponsive, press and hold [POWER ] for 8-10 seconds. The device will reboot automatically.
If this does not solve the problem, perform a factory data reset. In Menu
mode, select Settings ? Privacy ? Factory data reset ? Reset phone ? Erase everything

Hi,

On an Archos, battery is fully charge when the CHG LED light is flashing, while that light is ON all the time, the unit is still charging.

Now, in order to charge your Archos you must leave it on Suspended mode, by holding the Power button for about 4-5 seconds until it says "Suspending", DO NOT leave it on completely "Shutdown" mode, or your battery will never charge, and you are also risking the life of your battery by doing so.

So in other words:

1) On a PC via USB it should take around 8 hours to charge, while connected to an Archos mini dock, battery dock, or DVR Station, it should take around 3 hours to fully charge.

2) Leave your unit completely "Shutdown" (hold the Power button and wait 10 secs. or so until it says "Shutting down" and let it go off.

3) Connect it to your power source, either USB on computer, or external charging device as mentioned above, it will come back on, the two LED lights CHG and Power will come on, leave it like that, and after a few minutes the unit will go into Standby/Suspended mode by itself, and there is when you are charging your battery the right way.

3) Wait 8 hours if connected to your PC, or 3 hours if connected to an external power supply (as described above). If still after being in suspended mode (not completely off) your CHG light isn't blinking after the 8 hours on PC, 3 hours on external power supply, then suspect your battery is defective.

In that case, if the unit is still under warranty contact Archos, if it is out of warranty. If it isn't under warranty, you can buy a replacement battery on eBay and either replace it yourself, or find someone with the technical skill to do it for you.

I hope this helped you.

With the limited information provided, a simple first step is to make sure the internal battery is either fully charged or is in a condition to accept a charge. When the internal battery's charge is allowed to below a certain level, it will no longer be capable of accepting a charge via the car charger.

The battery can be conditioned to accept a charge easily, however. This is done by connecting the GPS to the computer via USB port, NOT the car charger. Some Garmin GPS units come with a 120 volt charger that connects to the USB port of the GPS - this method is also an acceptable charge / condition method. Leave the GPS connected for 8 hours or longer (over night) and try to power up again.

I hope this helps!

plug the unit in and press the silver button by the left side and make sure the unit is fully charged if not,plug in the home charger and iti will be fully charged 3 to 4 hrs,also if the battery is fully charged the unit should turn on after you press the silver button on the left side and hold for a few secs. without the car or home charger.also chk your cd manual for further info.let me know what happens.ok.
