In the first day of new 2016 year I tried to boot my HP laptop with Fedora. Little surprise: black screen after UEFI boot menu. Hmm, maybe the hardware is broken? I run the RAM and disks tests from standard HP suite and after 5 minutes they report: memory and hard drive is OK. Strange situation. Next step: connect HDD to my desktop, renew backups and check errors with
fsck tool – no effect.
