No power in my laptop. I press power button and only see red battery light for few seconds.

measure the output from adaptor example if the label printer says:17,8vdc, you will measure the exaclty 17,8 if do not , the adaptor is faulty. However the comuter must be run with the battery, of course must be full in charge. If does is o.k If it NOT , the power supply inside is faulty.repair
God bless you

Its an old trick that got my Dell laptop working
Unplug the laptop remove the battery press the power button,...nothing will happen, wait a few seconds put battery back in laptop plug it in hold upside down press power button until it boots
If that doesn't work it could be a bad/loose/dead bios battery What is the model of the laptop?

Hi there, this information comes straight from Nintendo's website. Anything I'd be typing would basically be repeating what comes from Nintendo directly:
Turn the Wii console power OFF by pressing the POWER Button on the front of the console. Unplug the power cord from the wall outlet for a few seconds. After a few seconds have elapsed, plug the cord back into the wall outlet.
Turn the power of the Wii console ON. When you see the Health and Safety screen, open the small flap on the front of the Wii console to find a red button labeled "SYNC." Press and hold the SYNC Button down for 15 seconds. This will clear all the syncs on the Wii, allowing you to get a clean start to begin the process described below.
After holding the SYNC Button on the Wii console down for at least 15 seconds, you can now "re-sync" your Wii Remotes:
With the first Wii Remote you wish to sync, remove the battery cover on the back of the Wii Remote to find a small red button just below the batteries.
Press and release the small red button just below the batteries on the Wii Remote; the blue lights on the front of the Wii Remote will blink.
Quickly press and release the red SYNC button on the inside of the white flap on the front of the Wii console (picture).
When the Player LED blinking stops and stays lit, the syncing is complete. The LED that is illuminated indicates the player number (1 through 4).

Red battery light means battery is charging. It should start up even if battery is low. Try pressing on the area above and to the right of the power button, while you are pressing the actual power button.

try separating the laptops battery for 8 Hrs to let the mother board discharge and cleaning the mother board and memory slots and cpu socket with the air blower

Seems to be a problem of not enough power.

First check the voltage output of the charger(adapter) and match it with its specs.


Also try to reset the hardware using the following steps:

1 Disconnect battery and the charger
2 Let it sit for 1-2 minutes.
3 Press and hold down the power button for 30 seconds.
4 Reconnect battery and charger and try to start by pressing the power button.

ok, take the battery out and leave it unplugged for a few hours.  Only plug the ac adapter in after.  Press and hold the power button for 10 seconds.  Does it still do it?  If it does work, then chances are your mobo has bit the dust or you have knocked loose an internal charging part.

Unplug it; pull out the battery; with the battery out of the laptop, press the power button for a few seconds; let it sit for a few minutes. Then reinstall the battery and see if it powers up. This method doesn't always work but I've seen it work on more than one occasion.

Have had this problem before with wii sports. What I did was turn off the wii console and unplug from the power, leave for a few seconds then turn it back on when the health & safety screen comes up

1. Turn the Wii console power OFF by pressing the POWER Button on the front of the console. Unplug the power cord from the wall outlet for a few seconds. After a few seconds have elapsed, plug the cord back into the wall outlet.
   
   
   
2. Turn the power of the Wii console ON. When you see the Health and Safety screen, open the small flap on the front of the Wii console to find a red button labeled "SYNC." Press and hold the SYNC Button down for 15 seconds. This will clear all the syncs on the Wii, allowing you to get a clean start to begin the process described below.
