Lenovo ThinkPad Yoga 11E-G3 11.6" Touch Ultrabook

It seems like a very solid laptop, good battery life, screen looks good, hard drive/RAM are decent size, runs fast enough. BUT the sound keeps dying. After a few days, it just died. No sound at all. Went through all the windoze troubleshooting, no help. Lost it for a few days to mail back to lenovo support, they reimaged the OS, a few weeks later the sound went out. Sent it back again, they said they replaced the motherboard, before long, sound went out again. At this point I tried to claim a full refund, but they said 'it's not us, it's a software problem'. MS auto-update drivers conflicting with lenovo drivers. Somehow (lots of rebooting, sound troubleshooting etc) the sound came back. We turned on auto-restore points, and created a restore point (google it). A while later, sound went out, restored to restore point, sound back, ok, so that's our workaround. Turns out apparently, if you restore to a restore point, auto-restore points is not on anymore, and the restore point you did use is somehow gone (used up?) Anyways, sound went out again, we have no restore points. Now I'm stuck wasting Christmas vacation going through microsoft hell to try to reinstall windows 10. This sucks so hard. This computer is used for 3 things: browsing, writing word docs, and listening to music. Should not be this difficult. Other reviewers had this problem as well, not sure why it didn't happen to each and every single customer of this unit. Word to the wise: when things are sunny and happy, create a USB install for win10 so you can use it to reset/reinstall when necessary. Also, turn on auto restore points, and for good measure make a weekly calendar reminder to check restore point history and/or create a manual restore point (only a few button clicks). Better yet, switch to Ubuntu.
