Hi!

I've just got my helix this week. Tablet work great except the keyboard dock not working. When I dock the tablet into keyboard dock, I got "Keyboard Dock Fan Error". I try to follow the suggestiong found in the forum to reset dock many times but not work :( (https://forums.lenovo.com/t5/X-Series-Tablet-ThinkPad-Laptops/Helix-keyboard-stopped-working/m-p/1120587#M20654 ). I also try to reset both tablet and dock but still not work.

- Charging tablet works (both plug directly to tablet or through keyboard dock)

- #2 Battery not shown in windows 

- Any other features of the docks are not working beside charging

- MPU version in the Bios is blank

I Can't upgrade the "Firmware Update Utility for Enhanced Keyboard Dock for Windows 8.1". when I upgrade I got "EC version mismatched......"

My System:

- Machine Type: 36984SU

- UEFI BIOS version: GFET43WW (1.22)

- Embedded Controller Version: GFHT42WW (1.19)

- System Unit Serial number #: xxxxx

- Windows 8.1 with update to latest lenovo driver and windows update.

Is there any solution to this problem?

Best,

Sovatha

Hi,

on the backside of the keyboard near to displayport there is the little hole for a reset - after doing the reset, it'll work (I hope so ...)

Btw. before the error appear - was the akku absolutly empty?

kind regard

Hi Dieter,

Thank for reply. I did tried the reset on the keyboard dock and it is still not working.

Here is what I did:

- disconnect power

- disconnect tablet

- use paper clip to reset the dock

- connect tablet back and plug in the power

Am I doing the correct procedure to reset?

For the battery, I am not sure about the battery level as it is not working out of box.

Best regards,

Sovatha

hi,

do the same with power connected - and push the resetbutton for 10seconds!!!

I waited at another hardware only 5 seconds and that was not enough ...

kind regard

Forget it! 

I did have a chance to upgrade it to latest version of MPU firmware.It work fine after upgrade and now stop working again after few of dock/undock and restarts. :( such and unpredictable/unreliable piece of HW.:catmad:

Hi

I would like to share what I did and worked.

I 1) connected the tablet to the keyboard, 2) switched it off, 3) press with a needle that reset tiny hole in the dock side, close to the ports (i do not have it with me right now but someone else wxplained it before in this thread), 4) kept press for around 10 seconds, 5) plugged the battery to the socket, 6) charged it for 2h approx, 7) switched it on (tablet and keyboard as a pc) .... it worked!

I really hope this can help someone else too.

Before that I reinstalled windows completely, as the first use of the laptop and keyboard was not working until the steps above mentioned, so i think drivers and software are not part of the problem but I may be wrong.

good luck
