Re: P52 - ELAN Touchpad driver (ETD.sys) issues (latency spikes, BSoD)

2019-03-22, 21:34 PM

I'm testing a beta driver... about 1 hour, no crashes yet.  When I use the touchpad - I'll typically get 1-2 BSOD's per day.  I'll let people know if it makes the weekend.

So far, so good - 1.25 days with no crashes when using the touchpad and the beta driver. Almost a record.

Definitely a record with the new beta driver.  All weekend - 2.25 days - no crashes.  I made it through 1.5 days before, but never more than that.  Fingers crossed...

Where did you acquire this beta driver?

I gave it to him.  He provided some BSOD dump files that ELAN analyzed and used to create a beta driver that hopefully fixes his specific BSOD issue.  If his testing continues to go well I'm hopeful that we can provide the same fix in a formal driver soon.  The lag problem is separate and still under investigation.

Yep - just wanted to report out to the group.  Hesistant to declare victory yet, but progress.  BIOS needed to be tweaked to run, def not production yet.  Be very nice to put this one to bed - I bought this computer to work - haven't lost anything to BSOD yet (that wasn't recoverable) - but it is just a matter of time unless the problem is fixed.

I'm glad to hear that the BSOD issue may be getting resolved! I've still only experienced the lagging, but it is nice to know that some of these issues are getting fixed!

Well it's been a week and no crashes or trackpad lag issues. So far so good.

Hi someotherguy, is there an update on the lag problem? It's frustrating enough for our engineers that we are considering replacing these new P52's with a competing product.

Thanks for your support

Beta driver appears to have fixed the BSOD issue - full week, zero crashes.  Subject to someotherguy and Elan, would recommend a broader trial.  I did not experience any significant lag issues, but some combination of the new BIOS driver and the latest BIOS update (released over the last day or two), trackpad response seems smoother.
