Hi,
My Latitude E6540 is having problems with the intel mangement engine drivers. The device refuse to work and this is causing my pc to take long to boot up and it is preventing the pc from waking up from sleep.
I have done the following:
1. installed the latest drivers from dell's site and downgrading drivers has no effect
2. tried to upgrade the bios from A15 to A16 but it looks like the bios will install but then it just restarts. downgrading also don't work
3. reset the bios by removing the bios battery and loading defaults in the bios.
4. Re-installing windows with updates and latest drivers.(windows 10 is running on it)
5. disabled/enabled everything in the bios
The laptop worked 100% but suddenly it started giving problems 2 days ago. A work colleague has the exact same laptop with exactly the same configuration and os and he does not have this problem.
Would this be a motherboard problem? can anyone help please
thanks
