5130, bios A07, Stylus A02, also have such problem for these few days.

Even re-seat the battery, might not work:emotion-9:

take off the head, you will find a small yellow point on the pen shaft,.

use some small and thin copper plate to extend the area size of point, it will have a good connection to the head screw

Same here, and getting pretty tired of it.  Gone through 2 stylus already, both died after about 30 min of use with new batteries.

Thx michael, works like a charm:emotion-21:

I have problems too with my reva02. It does not work! Replaced the battery and you can see cursor hover but I can't draw/write or select anything!
