hi, im having trouble after putting it down to sleep from the power menu, it doesnt wake up, opening the lid doesnt work, power button neither, keyboard just flashes backlights when touched.

it only responds when pressing for 5 seconds the power button and forcing reboot

all updates are installed up to date.

Hi, I have the same issue on 7480. I have some notebooks with Windows 10(kaby lake) and some with Windows 7 (skylake).

I updated BIOS to version 1.6.4 and I have last Intel video driver but still the same. When I open LID then notebook turn on lights on keyboard and power button but display is black.

Intel-HD-Graphics-500-P500-series-Driver_D5KD6_WIN_21.20.16.4627_A02.EXE

Only possibility is hard restart. This test was on Windows 7.

RE: Latitude 7480 wont wake up from sleep mode

hi robert, i updated the BIOS and all the other available drivers, and still have the same problem: cant power it on if it isnt connected to the electric current. if i put it to sleep running on battery it gets bricked.

it is a brand new unit with less than 10 times ussage, i bought it in malaysia, but i live in argentina, is the warranty still running here??

The "Computer Does Not Wake Up or Resume from Suspend/Hibernate Mode" page has completely generic suggestions - update drivers and BIOS or go to a general-purpose list of Windows error resolutions. This seems to happen to multiple people.

Isn't there something more specific to this problem?

rafavodo,

Did you purchase directly from Dell or a retailer?  If you purchased directly from Dell, did you purchase the upgraded on site warranty?  If so, you may be covered.  If not, then you would need to contact the seller and see what warranty service they can provide.  Dell may fix it for you, for a fee, if you contact Out of Warranty service in your country.

ok, so because i bought it from a retailer, DELL doesn't takes responsibility for a brand new, sealed in the box product.

this company is <profanity>, im so regreting of having invested my money here. its a <profanity> joke, hope mac crushes you
