Hi Dan, thanks for your reply. Yes, indeed, I installed the two drivers listed in Dell support page for keyboard issues, both somehow in connection with the touchpad (one from 2013, the other one Jan 2014, you can see the two of them under 'Mouse, Keyboard and Input Devices' here ->). Spintires Download Torrent. I don't know if they had already been updated before, or yesterday by me when I was looking for solutions, but even after installing them, the issue remained. I read somewhere about the memory and disk usage. But in my case memory was never above 30%, CPU was rather low, and disk usage remained below 5%, so it doesn't seem to be connected to that.

I'll try tonight unistalling all drivers and trying again. But since the issue started a week ago (and after windows update), not sure the driver has anything to do.

Click to expand.I get scroll lag every now and then, and very rare keyboard lag. I've always assumed (as you confirmed) that it's another process slowing things down. You might try (when you're offline and safe) disabling Windows Defender and its antivirus scans and seeing if that fixes anything. Sometimes when I get a hint of lag out of nowhere, it's because the malware scan is running. That, or one of Windows's other automated background processes, is probably the culprit.

Also, make sure that you disable every power-saving mode you can find (some of which don't work in safe mode), since one of those might be putting you in some sort of permanent throttled state. But basically, yeah, that shouldn't be happening.

*edit* Also, have you installed any printer or peripheral drivers? If so, try disabling them. Printer drivers especially can interact badly with things. Thanks peterf! Only seems to be a few of us Ivy owners on here now. Im wondering if youve experienced the problem im having. Back when I got the laptop, it had Windows 8.

I could go to the battery icon on the taskbar and select different Power Plans. Something like, 'Power Saver', 'Balanced', High Performance'.

I could really tell the difference between 'Power Saver' and 'High Performance', especially when playing my favourite game: Star Wars- The Old Republic. It would run very slow on minimum graphics setting on 'Power Saver', but would run great on medium graphics settings on 'High Performance'. After installing Windows 8.1 it seems to me like there is now no difference in performance between the three Power Plans. My game runs very slowly, even on minimum graphics settings on the 'High Performance'; its almost unplayable. It seems to me like all the Power Plans are 'Power Saver'. If you have any ideas, such as registry tweaks etc, I would be eternally grateful!

On a side note: I am trying to get a Haswell out of Dell. I have had the screen and motherboard replaced once due to IR issues and coil whine. The issues both exist on the replacement parts, so I need to ring again and get them replaced. How many times do the parts get replaced before Dell send a new machine out? Will it definitely be a Haswell they send out? XPS 12 9Q33 owners with Synaptics trackpads Enable middle click Open Dell TouchPad settings and go to multi finger gestures. Disable the 3 finger click gesture.

Open Regedit HKLM SOFTWARE Synaptics SynTP Defaults Set 3FClickAction to 4 Set 3FingerPressButtonAction to 4 You can try setting 2FClickAction1FInLeftButtonAnd1FInRightButtonZone to 4. This looks like it's supposed to mean what happens if you click with 2 fingers where 1 finger is on the left button and 1 finger is on the right button.

I set it to 4 (middle click) but it doesn't seem to actually do the middle click. Doing that kind of click does a middle click on the ty Cypress trackpad on the 9Q23 and on physical buttons on many laptops (with a registry tweak) Oh well. HKCU Software Synaptics SynTP TouchPadRMIHID2c Set 3FingerPressButtonAction to 4 Log off then back in. Middle click!!!

I can't believe it took me this long to finally figure it out but I've found a way to make the Cypress trackpad on the XPS 12 9Q23 slightly less ty! A good trackpad like Synaptics will disable the trackpad for some small amount of time when pressing a keyboard button and then re-enable it. The Cypress trackpad does this, but does it poorly.

It won't re-enable the trackpad until some amount of time after you last used the keyboard BUT only if you aren't touching the trackpad. It makes it VERY annoying.

But I finally found a way to fix this stupid behavior!
