I am having the same issue with my XPS 15z (L511z). Laptop is not waking from sleep / hybernate?

Does this Bios update apply to the XPS 15z or is there a different update?

HELP

XPS 12 Haswell w/ i7 just picked it up and also having the same issue. I upgraded to 8.1 and installed all critical updates to date. I have also updated the BIOS as recommended in this thread and still it has trouble waking from sleep. Keyboard lights up, CAPS lock light comes on, fans come on, power switch is lit, but no screen.  Any other recommendations? I might need to return this if not.

My XPS 14 has the same issue and it won't wake up from sleep. I have the laptop for a few months and it worked fine until last week (except slow wifi issue). A week ago It started having the wake up issue and initially I thought the laptop was dead.  I had to do a hard shutdown and startup every time after it went into sleep mode.  I updated the BIOS after reading the recommendation from the forum and it did nothing.

Please let me know if Dell has a fix for this issue.

That BIOS is a year old and has ben replaced by a newer version bios which still results in the same issue. I cannot sleep or hibernate without this issue and forcing a hard reboot.

Planning to return this laptop if no fix is available

I have Xps-12 9q33, bios is uo to date yet once screen then hard drive goes to sleep, currently set for 10 min & 15 min respectively on battery power, pc will not wake. the power button flashes and battery status lights will work.

DELL XPS 15z here, had identical problem as stated atop. I just recently changed my screen saver to standard one that came with this computer. My screen saver used to be one that rotated through pictures. Ever since I changed that it has been working fine. I am not certain if that was what had fixed however. Hope this helps someone....
