Lenovo Thinkpad 2 Tablet wont boot/charge

[ThomasWork]

20+ not used Lenovo Thinkpad 2 Tablets with win 8 on them refuse to boot/charge

Tried plugging them in and holding power then taking it out, tried paper clips in the hole to reset and also tried to connect it to a pc witch did not recognise it as a device.

Any help is appreciated in getting these things to work

Have you tried replacing the batteries?
