In March, HP pushed out a BIOS update that killed the motherboard on over 100 of our HP 840 G3s, and their customer service is crap to the point of insanity - one of the contracted engineers they eventually sent was only able to replace 3 motherboards in a day and was an utter prima donna. The contrasts with Dell customer service are night and day - Dell send polite, punctual, efficient chaps who get the job done.
At the time I was in hospital, bewailing my lot, but when I got back I found my poor colleague had it far, far worse than anything I had.
And that was just one incident - there have been others
Unfortunately the equivalent Dell on HE list is over £300 pounds more expensive, so we can only get them in special circumstances.
Bugger all to do with the 10 minute login black screen, but I need a good rant of Saturday, gets me set up for relaxing the rest of the day.
