I have a new Latitude E7440, the only install is office 2013. Out of the box, did windows update, did the 8.1 update.
If I put it to sleep (close the lid) and wake it up again, the system experiences slow performance - choppy youtube video, audio artifacts, Chrome and windows explorer hangs, etc. This happens on battery and plugged in.
If I do a hard restart, the issue goes away.
Once I saw an error flash from the tray saying the intel video driver had crashed and was resetting. Only caught a glimpse of it.
I tried reinstalling both video and audio drivers (including safemode-restart), including the pre-8.1 video drivers and I still get the same issue.
Anyone else having this sort of issue? Haven't found anything with search. Thanks!
Solved! Go to Solution.
I am actually having the same issue with slowness after I resume form sleep. The laptop gets unbearably slow if I am on any profile other than "high performance".
It is perfectly fast on the balaced and power saver profiles...until I put it to sleep and wake it up again. Then it gets slow.
Had this issue for quite a while driving my batty, was able to resolve in Windows 8.1 Pro running A15 BIOS by doing the following:
Boot to Safe Mode (Hold *** while clicking Restart - Choose Advanced Boot then Safe Mode upon Restart)
delete all files within C:\Windows\Prefetch (do not delete the ReadyBoost folder)
delete all files within C:\Windows\Prefetch\ReadyBoost
Run Disk Cleanup and delete all but Service Pack files
Reboot. (Should be fixed)
Thank you Mark Bohn @ Dell ProSupport for helping me resolve this and my IgfxTray crashes!
