I have a 5 volt linear power supply that I want to use instead of the Dell switching mode AC power adapter

that came with the tablet.

My power supply only charges at 400 mA and takes at least 12 hours to charge the tablet.

Can someone tell me how to get my power supply to charge at full rate?

So far I tried shorting the two USB data lines together, but that didn't work.

Then I put a 500 k Ohm resistor from the data lines to ground to no avail.

The Dell  power adapter has about 200 ohms between the data lines, and 500 k ohms

between the data lines and ground.

The dell AC adapter is an electromagnetic nightmare. I cannot be in the house when

it's on, due to the noise that it produces. It causes a severe headache and ringing in the ears.

Thanks,

Eli
