I own an ACER Chromebook laptop. I bought it to replace my Windows 7 LT. I didn't like it so I bought an HP LT. I now use the CB as my bedside table TV. I am a PLUTO TV nut. The last 2 months, or so, when I'm watching FORENSIC FILES on my CB, it suddenly stops and goes to my screen saver. I have to sign back into PLUTO TV and hope it stays put. This usually happens right after an episode is over, before going to the next episode. I have been watching other shows on PLUTO TV and it does the same thing. Sometimes it goes off in the middle of the episode. When I first put the CB in my room it never did this. Any ideas what's going on?
