Hello I have venue 11 PRO 7130 with Intel core I3 and I had the same problem.
At the begining everything worked well. I updated the tablet to the Last Bios (A09) and and the issue come up.
the touchpad still works but is uncontrollable while the keybopard works welll.
I do not think that is related to Bios actually. I have also the Slim keyboard and the I have no problem with the touchpad but just some occasional diconnection that recovers after pressing the windows button.
I'm waiting for a replacement hoping the new keyboard does not have this issue.
I would like to see somebody of DELL repling.
Even after opening it my touchpad stopped working again after fully charging the battery. I cracked open the case again. Removed the battery connector and my touchpad works. Connect the battery and the touchpad stops working again.
This is with a fully charged mobile dock battery, once the battery dropped to 90% or so on the keyboard I replugged the battery connector and its working again. Seems like the battery or charge from it is causing some fault with the circuitry
If it fails again I will just remove the battery all together, at least it will work!
Confirmed that this is the exact same issue with my keyboard touchpad. After full discharge it works and then once charged it no longer functions.
I opened a case with Dell support and they tried to set me up for a motherboard replacement. I explained that I already had an A01 motherboard and they are now sending a new keyboard (which I'm sure will have the same issue). They told me if that does not work, they will replace the motherboard. Apparently this isn't a well know issue yet.
Well there are a few of us now and I think it will be common as more people use the mobile travel keyboards. I have also learnt when fully charged disconnected from the tablet it seems ok.
But if I leave my dock fully changed and connected to my V11p it will then over a certain amount of time cause the touchpad to die on me. Very odd faulty, but its a fault alright.
I received my replacement keyboard. The new replacement works great even with a full battery charge. They even let me keep the old keyboard with the unusable battery.
