Re:Trackpoint randomly stops working

2021-10-02, 12:56 PM

Hi there...

 

Ive been using T490 - 20RXS0W100 for around a year, and Ive consistently experienced trackpoint loss.

a) It has only happened when using it on battery, but could not say if it could happen on mains (when docked on mains, I use external mouse), 

b) Normally it happens when I use more pressure than normal (ex Im traying to get to the top of the page fast), but not always happens. When it happens, normally Ive just pressed it harder... but not the other way round.

c) As commented by others it resets and starts working again after sleep or reboot of the machine.

 

All windows updates, and  al lenovo vantage updates.

 

Help please.

 

Thank you

Juan Pablo

Okay so, despite that power save disable stuff, my trackpoint froze today. Funnily, I dropped these lines to IRC:


14:25 <me> heh, it would be really funny if my 1 hour research would solve this mouse problem

...

14:31 <me> HAHAHA of course this piece of **bleep** broke down just now

 

So, I have approximate timespan for Event log scavenging.


First Application logs:

 

 

As you can see, last event before confirmed crash was from SynTPEnhService. The igccservice is also worth mentioning, it says "PowerEvent handled successfully by the service.".

 

Next the System logs. One dubious entry preceding:

 

 

I have no idea how a mouse could be causing this kind of power management(?) triggering.

 

("Funny" sidenote: I put the computer to sleep and woke it up. It went totally haywire. There was no password input screen anymore, just regular background. I had to do hard reset. After hard reset I struggled for 15 minutes to get the system to boot AT ALL. I was finally able to hit F12 during one boot and got to select the right boot device. Btw. I had something like this with an earlier X230, it would not boot again from SSD without F12 tricks.)

 

Well the next step I'm going to try, I'm disabling completely the SynTPEnhService service:

 

 

I have also other tricks up my sleeve but this is my next step.

No problems on Windows 11 (yet). But only installed it Friday (i.e., 2 days ago).

2021-10-06: SynTPEnhService.exe disabled, had trackpoint crash again today, at 16:35 or 16:36 local time. Did absolutely nothing out of ordinary. (Too bad I cannot edit my own post for some reason to clearly indicate this was not the fix)

Details of todays crash:

 

Was doing absolutely nothing out of ordinary. Had been typing and working for some hours. Charger connected the whole time. There was almost no traces in the logs. Just this random stuff paraphrased:

 

Microsoft Platform Crypto Provider  Key Name:    Windows AIK

 

RPC call to function WLIDCreateContext returned the following error code: 0x8004800C. Source: LiveId.

 

Process Teams.exe' (PID 1496) was blocked from making system calls to Win32k.sys.

 

Skipping license manager: PFN Microsoft.SkypeApp_15.75.140.0_x86__kzf8qxf38zg5c
Function: InvokeLicenseManagerRequired
Source: onecoreuap\enduser\winstore\licensemanager\apisethost\activationapis.cpp (373)

 

Funny thing is, the trackpoint froze again while I was getting the log entries and typing this post.

 

Too afraid to open this, this is a machine provided by client to me. Otherwise I would hook up my serial decoding oscilloscope wiring there and see what an earth is going on between mouse and motherboard. Maybe I should sell my diagnostic services to Lenovo, lol.

trackpoint had been working ok since i disabled the touchpad in bios.  HOWEVER, yesterday the pointer became "difficult" to move and would suddenly take off on its own to one edge of the screen or another, quite randomly.  rebooting , after the several times this occurred relieves the problem but is still returned ramdomly.

Now I'm finally out of humour. This T14 mouse is total garbage. I have had yesterday 4 trackpoint crashes. Today like 2-3. All requiring reboot or reverting to stone age and external mouse.

 

I cannot use this machine to work.

 

I repeat: Thinkpad T14 is unusable for serious work until this mouse problem is fixed.

 

Lenovo, get your act together.

I'm with you.  I've been on this forum watching this problem brew for months now.  Is there something we could do collectively to motivate Lenovo to get off their ass and do something?  Social media?  Looking for a solution here.
