SVE1513 running Windows 10. Shut the machine down as normal but the machine did not shut down properly. Screen was off but power light flashed occasionally and the machine squeaked, like a mouse- no pun intended. I usually work with the power cable connected. I had the remove power and battery to shut it down. Then it wouldn't load windows. I tried evrything inlcuding the recovery media. Eventually it got it going and have had several blue screen since. It is now working OK if the power cable is removed. I suspect it also works with power connected but battery out. In the latter case the machine is sensitive to movement. (Shuts down if i move too much.) I suspect the power input socket but why the blue screens? help please.
