Charging I plug the charger in, but it tells me that it is unable to charge. It does the little noise that I've connected this, but it won't charge...why?

Sometimes "intelligent" chargers will not start charging if a battery is too flat, but usually there will be at least a light showing that there's power to the charger.
You could try jumping a good battery across the one you want to charge to get things going (+ve to +ve, -ve to -ve).
If it's broken it's usually worth a look if you can get it apart. Look for a blown fuse, bad solder joint, wire broken, something burnt out etc. You might be able to fix it.
Don't plug it in while it's apart unless you are certain that nothing will short out and that you will not touch any live wires!

This is a common problem. It may be that the charger is dammaged. these Dell chargers have a micro thin communication cable in them that tell the charger to charge the battery. this micro thin cable can often break. Its use it to prevent the laptop battery from over charging, but if it breaks or becomed broken inside tha charger cable, then the laptop simply won't get the charge signal and the battery won't charge. If this is the case, then you will need to replace the charger with another Dell charger compatible with your laptop

It sounds like the charging port on your phone is broken. This could have happened a number of ways. Either by dropping your phone, putting the charger in wrong, or taking it out wrong. If you call HTC(866-449-8358) and it is still under warranty they will probably fix it for free as long as it doesn't have any water damage(http://www.ehow.com/how_4479971_check-cell-phone-water-damage.html). Otherwise you could also get a new phone.

If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

If it does not work with the Charger while the battery is out then I would say either your charger is bad, the dc power jack where the charger plugs into the laptop is bad or you've got motherboard issues. Does the charger have a light on it to indicate that it is on when plugged in the wall? Do you see any lights when you plug the charger into the laptop?

Take an ink pen and see if the little pin inside the computer where the charger plugs is loose and moves a bit. If so that is probably your problem. If the pin is tight and the charger works, then you've got motherboard issues.

I have many times repaired small electronics with this problem by checking the solder connections from the power jack to the circuit board.(I am self taught,not an expert)Anything that plugs in to the device can easily break the connections to the board.Electronic manufacturers do this construction technique to save space,but I would rather have the jacks connected to the board with short pieces of wire.(I recently scored a Magellan GPS in the dumpster at work-someone pitched it WITH THE CAR CHARGER because of the same problem)It took me longer to figure out how to get the case open than it did to fix it!

My Motorola Blur would not charge kept saying Connect Charger. I tried various power connecters including the Original one that came with the phone and the USB to no avail. This morning I took the phone apart and clean it and still would not recognize the charger.

Fix: I lifted up the connector where the charger plugs into on the actual phone and now it is making contact and appears to now be charging my phone.

Have you tried another phone charger? I had a motorola charger that had a bad plug on it and it wouldn't connect right. The phone could recognize that the plug was connected, but could not route the voltage through it, thus telling me it was "unable to charge". If that's not it and another charger doesn't work either, look at the connector on the phone. See if there is any dirt or debris in it. If so, try to clean it out. Also, if you got the connector wet, it can corrode rather quickly. If this is the case, you may need to use a drop of isopropyl alcohol to clean the contacts. Hope this helps. Good luck.
