My Eee 4g surf netbook won't charge at all. Upon turning it on, it runs for a second, then shuts off due to a lack of battery power. The charge cable's light is also not turning, so that may


I think your DC Power Jack is bad. The DC Power Jack is where the power cord plugs into the laptop. If it is bad, then a good power cord cannot charge the battery, nor can the laptop turn on once the battery is drained.

You say it smelled burnt, that might mean it took a power surge. I always tell people that before your plug the power cord into the electrical outlet on the wall to remove the other end of the cord from the laptop. That way if you get a power surge you will only damage the power cord and not the dc power jack or motherboard.

Anyway, take an ink pen and push it into the dc power jack and see if there is some movement. The little pin or the casing of the jack should not wiggle.

The DC Jack is soldered onto the motherboard. To replace it you will have to take the laptop apart, desolder the old dc jack and solder a new jack onto the board. Sometimes the DC Jack sits in a slot rather than being soldered. The palmrest and bottom case helps to keep it in place. This type of DC Jack usually has a cable harness that plugs into the motherboard.

I have a desktop PC that when I turn it on it will power up and then after 6 seconds turn back off.


The first solution is right on the money, It's the video card, or many of us today forget to plug the damm thing in and the computer doesn't read and we think that there is a serious problem. If none of this helps then try troubleshooting through this PC repair guide. Hope this helps.

1. remove the main battery
2. remove any USB cables etc., if connected
3. hold the power button for 15 secs.
4. reconnect the power adapter (Do not install the battery yet)

Later if the system starts well then shut down the Laptop and install back the battery and connect the charger and start the Laptop again

Dell Inspiron works on battery only. No AC, no charger.


get a volt meter and be sure the power is coming to the plug, you may have a broken cord. if the problem is not there see if you have a setting in the bios for dc only. some older dells have a bios setting for the power settings in bios.

Delll Inspiron 2200 Laptop does not power on


You have all the simpthoms of an overheating laptop.
For starters, get a vacuum and **** all the dirt from the fan or fans on the back/ bottom of your laptop.
Then turn on your laptop. It should stay longer than 5 seconds.
If this solves your problem, then you are lucky.
If not, you'll need to have your laptop serviced, and clean the heat sink, and have reapplied the heat transfer compund on the processor.

Not a big deal, and not that expensive either.

Laptop wont boot.


do you get any video on the screen at all? in either case, it might be a motherboard problem, but try taking out your battery and unplugging power. wait a few minutes, then put them back in and try to boot. if you're still getting lights but no video or functionality, it's probably a motherboard problem and you're looking at having to get a new computer, or a very very very expensive repair.
