Hello!
I have quite a situation with my don't-remember-how-much old laptop (>3 years is for sure), which's Inspiron 17R 7720-6167 with dual boot Windows + Ubuntu on two different HDDs.
Not a long time ago, my computer started to not boot sometimes. Not boot means: power button glows all the time, hdds start to spin as I can hear, cpu n all started working, all leds started glowing correctly, but puff, and just... silence. Power button still glows, though, just as a side led for "Power". But it just silently does nothing. No hdds spinning, no "beeps" from BIOS, no glowing of other side led (except for Power one ofc). Oh, and power supply led glows ok too.
But, if I leave it for some time, laptop will likely boot. Diagnostics showed nothing particular: everything is ok, except not having a battery (got a warning for it 1y ago or so, didnt really need a new one) and short self test failure for the main drive. I will list SMART-test result for this drive below.
Other symptoms:
Noticed that Ubuntu sometimes freezes during any IO-heavy operation, such as copying of a lot of files/big files.
Encountered a few errors during copying on external drives, such as unremovable folders or something. E.g. I deleted folder with files, but the folder itself stayed not touched, and gave me 0x80004005 error out of blue next time I tried to delete. Standard Windows error fixing for drives fixed it, though.
Tryed removing memory. Beeps 2 times just as expected. But if I put it back, 4 times out of blue. Ok, I moved to another slot (have one 8gb module), worked ok. Strange.
It's not covered by guarantee, I guess, as I had, afaik, standard 1 year one. That's why I seek for help from you guys.
Thanks!
