This is an update on the HP Executive Tablet Pen for the "G2" Atmel devices. In my case it is for my Elitepad 1000. As of this writing we know there are two versions floating around; R1 and R2. I believe mine to be an R1. After approximately 3 months in service I began having issues with the pen shutting off and not waking up. It also began skipping while inking and exhibited very short inking times where it would turn off and not come back to life. Trying to select things on the screen was also difficult because of the intermittent operation. One would think this was a battery issue but opening the pen and mechanically cleaning contact surfaces on my shirt would get it working again. Like the early N-trig pens or the new Dell Synaptic pen, this is consistent with contact corrosion as a root cause. Contact corrosion has basically similar symptoms as a dying battery. The resistance of the contacts creates a voltage drop that reduces the potential of the battery. In effect it makes a fully charged 1.5v battery seem like it is a much lower voltage. The contacts in the 'circuit' are as shown in the photo below; 1 and 2 are on the battery, 3 is the spring at the end of the barrel on the inside, 4 is the threads on the inside of the barrel, 5 is the positive tang on the circuit board, 6 is the threads on the housing, 7 is the field coil on the front of the housing, and 8 is the pin on the nib. The cleaner I tried is the CRC Electronics Contact Cleaner. I will save the WD40 in case the CRC fails. I sprayed each of the 8 Contact areas and then used a paper towel to mechanically clean the area. I let it all dry for approximately 15 minutes and then reassembled the pen. It has worked well enough now to allow me to write this entire post. My inking performance has been restored! If your pen is exhibiting these symptoms and your battery is still 1.0v or more as checked with a volt meter, then cleaning is needed. I hope this helps!
