Got a Y5070 about a month ago, 11 months left on the warranty. When I received it, I replaced the HDD with an SSD, and upgraded RAM to 16Gb, and installed Windows 10.
Ever since I've had it, when on battery I would get random power losses. Exactly as described here: https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Lenovo-Y50-70-Sudden-Crash/m-p/2093711#M124398
The solution to that poster's question was to "reinstall OS because of NTFS error". Since there are multiple users complaining about the exact same circumstance, I can't believe that an OS reinstall will fix it.
When it happens again, I'll get the dump file and event log entries and post them here.
