Kindle DX Battery By Pass

Hi

I'm looking to use a Kindle DX as a remote VNC monitor and as such it will be powered via USB constantly.

To avoid the battery dying as a result I tried removing it however once removed the Kindle DX won't power on at all.

I'm wondering if there is a way of wiring the charge and sense battery terminals in such a way as to trick the Kindle charging circuit into thinking there is a battery installed and allow it to boot as normal.

Has anyone had any experience with this type of thing?

Thanks for any help.

Cheers

Dave
