My girlfriend's laptop was not booting. In fact, I could not get into BIOS setup so booting from an alternative medium was not an option. The simple things I tried (remove DIMM, remove HDD, reset CMOS,
They asked nearly $100 for a "diagnostic" that looked something like this:
"No signal from keyboard" - read: F1 won't enter BIOS setup (that was why we brought the laptop to them in the first place)
"No signal from CD ROM" - read: our diagnostic CD doesn't boot (again, that was why we brought the laptop to them)
"Hard Drive OK" - strange, we removed HDD before giving the laptop to them
"RAM OK" - the only thing they have done with the laptop was trying another DIMM (if they were not lying on that one too)
"Motherboard error" - they implied that exchanging it would be too expensive and the laptop is not worth repairing.
(BTW I was able to fix the laptop with some help of Google afterward. The problem was short-circuited wires in a broken USB slot. The laptop still works well 1 yr after the "incident".)
I was furious so I spent really long time arguing with them. They repeated several times that they ran "series of diagnostic test" but when I pressed the manager he had to admit that they couldn't run the tests because they couldn't boot their diagnostic CD. At that point, the manager denied they lied to me about the "series of diagnostics" and started calling his technician (who was not there at that point) "a mysterious man who told you something".
My girlfriend never seen her money again. I filled a complaint at their corporate support line. They told me they will handle it but they will not tell me about the outcome (WTF?). All I could do was to call again the next day to check that the complain was in their system and it had assigned a tracking id.
I was seriously considering taking some further steps because I consider this preying on a layman public bordering with a fraud. But at the end I just gave up.
