In AHCI mode system boots without problems but only when AC Adapter is not conected. Otherwise it hangs up.

Re: Dell e5420 hang when AC Adepter is connected

I was just thinking about this case and one thought came in mind is WHY system Hangs only when power adaptor is connected ?

does it has something to do with system power options ?

what are the options selected

1. On battery

2. Plugged in

and as system is running fine when its on battery , what if we change Plugged in plan same as On battery ?

Re: Dell e5420 hang when AC Adepter is connected

It happens on a few e5420 notebooks so I assume that they don't have any hardware errors.

It hangs only in pre-boot (I write password and it hangs). If I connect AC Adapter right after login in it works ok, so meaby it is not a problem with power options (if we talk about power options in windows. I did not find any options like that in BIOS). So the problem occurs only in pre-boot.

keyurshah which version of BIOS do you have in your notebooks?

We had something very similar to this on our HP tc4400's.  It would lock up right after typing in the password.  A newer version of EEPC resolved the issue.  The problem was if the computer was on the docking station it would lock, if it was not it would boot fine.  Perhaps try 5.2.10, make sure you have the latest bios too.  Are you using a docking station with these systems?
