Dell deletes Latitude CPU Throttling issue after link is posted here.
Dell's new Latitude 5420/7420/7520 Notebooks have a ongoing issue where their CPU are severely throttled when running on any Linux distribution, even on Ubuntu OEM Certified System according to some reports at the forum.
After a link to the Dell forum post was ported to HN, the post mysteriously was deleted in the same day. Many users of this model posted to the forum thread since last year and so far no solution was provided and we only received very unenthusiastic responses from Dell support.
Shocking to see this apparent action to hide the problem.

Then the battery. Oh the battery. The computer would randomly wake up from hibernate and drain the battery till it was dead. This also caused premature drain. Guess what? Dells batteries are rated for less cycles (half compared to apple) and this seemed to coincide with the end of my warranty period (time to buy a new one) but it doesn't even matter because their premium support only covers battery replacements for the first year!
And get this! They only sell refurbished batteries. Just everything about this company is trash.
The XPS is a nice line. It is very premium, but only skin deep
