Hello,
I got the typical error for my HP Omen 17 System. At first I thought it was a Hardware (Fan issue) but it wasnt so I digged the HP Forum to find some solutions for it. But it seems my Laptop got the usual OMEN ck2**** Error. My FANs do not operate like they should, 95% of the time the dont even react and stay off.
So I replaced the FANs cleaned the FANs, put new paste on CPU and GPU and thought It would fix the problem. Checked my BIOS and drivers, did a Hardreset the typical stuff the QR-Code tells me to do if you get the ERROR. After replacing the FANs etc. first I thought its fixed. But no, after 2-3 days I got the Error 90B again. So my question is, because its a really know issue for this type of laptop from HP, will I get a replacement? Ofc the warranty isnt active anymore. So is there a way to get some of my money back? Because 1,5 years lifetime for a 2.500€ is pretty insane. Does someone have informations for steps I could take?
So it seems the problem is cause by the motherboard and the FANs may not get enough power to be active?
But why are they working every 20th time?
The real issue iam referring to: https://h30434.www3.hp.com/t5/Gaming-Notebooks/OMEN-17-ck1000-ck2000-cm2000-intermittent-fan-dysfunc...
