Keyboard partly dead

[Wille]

Suddenly part of keyboard went dead. Numbers from 1-7 and sometimes also letters from q to y (now seems to work). Perhaps  loose connector, but where to start looking for it? I'm not counting device has any warranty to cover this...

Bad luck  

I don't know exactly where to look.  But a general principle for gadgets and machinery is that the moving parts are the most likely to have trouble.  The Gemini's moving part is the hinge, and what surrounds it.  In particular, there are almost certainly ribbon cable(s) carrying power and signals to/from the keyboard, ports, &c -- cables which flex every time the Gemini is opened or closed.  Those seem the most likely sources of trouble.

(I'm also drawing on years of experience with Psions: hinge mechanisms and the connectors around them were always the weak points.)

First thing I'd suggest is to contact Planet; it seems they can be quite generous when it comes to troubled units.

Otherwise, I'd try removing the top panel, bottom panel, and hinge panel, and try to make sure the ribbon(s) have their ends firmly seated, &c.

And I hope you get it sorted!

I contacted Planet and they suggested to send device for service.
Before doing that I'd like to get backup from userdata partition. I can see that flash tool supports readback but can it be used to retrieve userdata from the device to disk and restore back afterwards? It requires begin address and length, so can I use begin address as stated in Download tab for userdata? Length needs to be calculated..

I've not done that, but I expect it would work.  I think you'd need to use a scatter file that matches how your Gemini is set up; that file specifies the location and size of userdata and the rest.  If you flashed your Gemini, you should use the scatter file you used at that time.
