I have got problem with my Dell e5420. EEM version is 5.2.9. AC adapter is connected. I start my encrypted laptop and after about 5 seconds it hangs. (McAfee login windows appear and hang). Without AC it works fine.
Has anyone know what is wrong?
just one machine, or lots of them behaving the same way? If it's just one, I would suspect a BIOS problem and look to see if there's an update available.
I try to reinstall originaly installed Windows 7 by Dell. meaby there are some drivers problem or other 'strange' dell software. It works fine without EEM, so...there is no Dell problem. I'll let you know about results.
Unfortunately, after many system reinstalations, on a few e5420 laptops, it still hangs. So my problem is still unsolved. If someone has any ideas, please, let me know.
What HDD Access mode is selected in BIOS ? It should be SATA AHCI only in dell laptops.
We have a similar laptop series it works fine with EEPC, no issues.
