I have a Dell Venue 11 Pro 7140.
I love this thing. I recently just got the Active Stylus for it and I love that too. But because of using the stylus, I have to remove it from the keyboard, and reattach it. Well, the keyboard does not work now. It recognizes the battery and that is it. Nothing changes in the device manager either.
Last time this happened, I simply disassembled the keyboard, unplugged the battery, and plugged it back in. Everything worked fine again. However, if I have to keep doing this each time I disconnect my tablet to use the stylus, what the ***.. That is absurdly stupid. There has to be a "fix" for this or something.
Update the BIOS, chipset and Dell firmware from the Dell Support site.
What is the model of the keyboard used? Was there any recent software updates completed on the system?
please click my DELL-username and send me a Private Message with the Dell Service Tag number and serial number for the keyboard, so that we can check on the specifications.
