[ltp] Problems with (non-Lenovo) battery

[Jason Brooks]

lenovo has a bootable cd image to do the reset procedure. It is listed
on the t30 driver file lists. I don't think it will help. I only had
the blink problem with apc and after market batteries. It is a normal
thing. Only it is my battery light that does it on the t30 not the
wifi lamp.. I don't have a wifi lamp.
