3hrs of charging only up 4% WTF - Asus Eee Pad Transformer Prime

Read through al the other charging issues posted and can't find one like mine. So here is my issue.
Prime been working wonderfully then yesterday was on it watching netflix videos and while plugged in it kept loosing charge until it was down to 5% on tablet and 0% on dock. So I shut it down and left it plugged in all day. The battery icon showed the lightning on it stating it was charging but after sitting for about 4 hours nothing. still showed about 6% charge on the tablet and 0% on the dock. So I tried another outlet and eventually left it plugged in all night well this morning still only about 15% charge on the tablet and 0% on the dock.
Going to try again and leave it turned off all day and see if it charges, will report back in 3 hours on my lunch break to see if anything changes. The prime recognizes when the charger is plugged in and when I unplug it I get the message that it is low on battery. Here's a screen shot of it stating it is charging.
Also note: Neither light on the power button or on the dock is on while plugged up but yet it shows charging on the lock screen.
Edit: plugged in directly to tablet to wall and only has gone up to 8% charged. Seems something wrong somewhere. Tested charger on SGS and it works, hopefully just the cable gone bad. Will order new one to see if that works, but until then no prime for me. :crying:

what do you mean tested your charger on SGS and its fine?
the Prime has a proprietary plug and cable that only works in the prime and dock where as the SGS just uses micro USB.
what part did you use on your SGS?

Plugged my SGS charger into the black box of the Prime, plugged that into the wall outlet and i get charging icon on my SGS is what I mean. So the black box itself seems to be working. No way to test out the cable itself seeing it works only on the Prime.

Only had it in for a second to see if it was sending a charge.
Update: Have had prime plugged into wall completely turned off. Still no light on the dock plug in or on the tablet itself and now after 6 hours it is only 7% charge. This is pissing me off.

If you have a test device try to check the delivered voltage from charger, if it's correct it' s a hardware **** in Prime, or a bad connector in cable.

The Prime charger delivers 5v when another non-Transformer device is connected. Otherwise they could not use an USB standard connector for the charger

Found out issue. It was my power brick. It is not bad it is just doing a trickle charge to the prime for some reason. Here's how I figured it out.
Did some research and found out that the following charger and adapter does work on the Prime to charge it (Using it now) with the OEM USB Cable.
Radioshack:
Enercell 12VDC*1.5A AC to DC Power Adapter Part #273-358
Enercell Adaptaplug USB_A Socket Part # 273-227
Total Cost $24 bucks and the first adataplug is free.
