This was likely the cause of the PS/2 bus lockups: the components running off that voltage supply (touchpad, keyboard, and associated microcontroller) were unlikely to work reliably at 2V. Most interesting was what happened when the keyboard was disconnected from the tablet, leaving it powered only by its internal battery. Note that the button may still work in this state (as I recall someone else on the Internet noting). Essentially the touchpad PS/2 bus was in a locked up state. In the broken state, pin 3 was stuck low (0V). In normal working operation, five of the six pins - all except ground - probed as 3.3V, which is the normal idle state of the PS/2 bus. The pinout for this connector looks approximately like this: Pin

The first thing I did after removing the cover was to probe the 6-pin touchpad connector, since that was the most obvious point of brokenness. But I thought I would try to track it down. Most people at this point would call Dell, and unless youвЂ™re an electronics geek this is probably the best option. Strangely though, if I disconnected the battery inside the keyboard or let it drain completely, it would always work reliably, so I knew that it was some interaction with the voltage from the battery. Sometimes the whole keyboard wouldnвЂ™t work. Sometimes after attaching it to the tablet, the touchpad didnвЂ™t work. I ran into an interesting problem with the travel keyboard, or at least my unit. I chose the latter version with the battery inside so that I could get more battery life out of my tablet. ThereвЂ™s two types of keyboard available for the Dell Venue 11 Pro: a вЂњslim tabletвЂќ keyboard (K11A), which is just a keyboard and touchpad, and a вЂњmobileвЂќ or вЂњtravelвЂќ keyboard (K12A), which additionally has a battery in it. Together with my Dell tablet I bought a keyboard. Even if you donвЂ™t have any interest in taking apart your own devices, I would encourage you to consider the fixability of your device and vote with your wallet against throw-away devices. Batteries have a limited service life (as I know all too well from my last post), and I donвЂ™t want to throw away a perfectly good tablet in a couple of years just because the battery is not holding a charge.

One important reason I chose this model is because they are more easily serviceable than other comparable offerings like the Microsoft Surface Pro line the Surface Pro is glued together in a way that is difficult to disassemble and reassemble, which makes me very unhappy. I figured this would be a good crossover device between a tablet and a laptop, and so far IвЂ™m not disappointed. I recently purchased a pair of Dell Venue tablet computers - one for myself and one for my girlfriend.
