Have this curious problem that seems to be happening more frequently than a year ago when I bought it. Unit is a Lenovo ideapad U310. I'll have the machine on and can be working, sometimes I'm away from it for 10 minutes and come back to it and it's doing this: Everything frozen with screen on. No mouse, no touchpad response. Both power lights on the front of the case are on and not blinking at all. Only recourse is to hold the power button until it shuts off and re-start.
(Also have another curious question, but should post seperately, as it happened twice as I was typing this - cursor just bolts from where I am typing to another area of text and I have to go and backspace several words from where it is now typing).

This seems to be a random occurrence, but I'm suspect that maybe it's Google Chrome and the abundant amount of tabs I'll have open (on a usual day, can be around 15 tabs). But I think I've seen it happen with fewer tabs open.

Specs on my system are as follows:
Windows 7 Home Premium 64 bit, Service Pack 1
Intel Core i5 - 3317U @ 1.7 GHz
4GB RAM

I've done a little research on Tom's forums and someone did mention that there is the possibility of expanding the RAM to 8GB, but I'd really like to know where the problem stems from before I go buy an $85 stick of RAM.

It sounds like you may be hitting your ram limit and the computer is using virtual memory (aka your hard drive) as ram substitute. Its likely that, or a failing hard drive. Best bet is going for the ram upgrade another 4gb. Of that doesn't solve the issue, I'd guess it is a hard drive issue. Download HDTuner and check for errors that would indicate hard drive problEms

delellod - I've done that and performance varies.
Right now I have 23 tabs open with 3.25GB of memory being used and CPU usage varying between 11-22%. I did watch it shoot up into the mid-50% range when opening even more tabs.
What I don't know is what happens the split second before the computer locks up. You'd have to sit and tinker and open more tabs and maybe even some programs and be able to see that performance level as it freezes because once it does, you wouldn't be able to get to it.

Also of note - in the performance area - Physical Memory was up in the mid 90% range a few minutes ago but has dropped to the mid 80%'s.
