NV Cache is full

I'm having a fairly diastrous time working on a new Lenovo X61 tablet PC.
The system is hanging repeatedly so that only a reset will allow me to
communicate with it again. I suspect I am going to have to reinstall the
operating system but, before I do that, I'd like to get an answer to a
specific problem. I am getting a message that my NV cache is full. The
warning includes an option to click on the window to take me to another
window (Disk Cleanup) where, nominally, I am supposed to remove files to
clear space in the cache. Following through on that, I am offered the option
of freeing "up to 0 bytes of disk space on NVCACHE (E:)", i.e., there are no
files to be removed. If I open "Local Disk" NVCACHE (E:), I see only one
item: ReadyBoost.sfcache with a size of 506,881 KB. I understand that this
is a system that is supposed to speed operations by limiting calls to the
hard disk, but I don't have any idea of what I am supposed to do to free up
space on it. Can one erase the ReadyBoost.sfcache without further disturbing
my already pretty disturbed system?
 
You may wish to contact Lenovo Support and ask them for assistance:

Just an FYI update. I actually have been in pretty regular contact with
Lenovo support. They didn't have an immediate response but eventually
indicated that I could erase the ReadyBoost.sfcache. Unfortunately the
system would not allow that, i.e., it just refused to execute the command.
I've since wiped everything and reinstalled the factory setup state. I have
not activated the Intel Turbo Memory again, as I am assuming that was the
origin of the problem with the NVcache. The system (I am assuming this is
Vista because it happens in all kinds of applications, including, for
example, Windows Journal and Word) still hangs regularly (well...not
regularly but more often than is reasonble). I have developed the habit of
being very careful when signaling commands and to try very hard to avoid
clicking anything if the "busy" icon is revolving. I'm hoping SP1 solves
some of this.

Hello there...I'm having near identical issues with my new X61
Tablet. Initially I was blue screening on a regular basis and an
update to the power managment driver as well as the AHCI controller
from Intel seemed to calm that down...however, as you indicated
above...it still hangs on a more than acceptable basis. When it does
hang you can, for lack of a better description, feel it coming. Any
number of applications or windows becomes unresponsive and the more
you click on, the more the list of unresponsive items grows, including
Explorer (Start menu) and task manager. Rarely does the mouse lockup
but aside from mouse movement...the machine works itself into a
totally unresponsive state and needs and a cold boot becomes your only
friend.

What I have found is that this only tends to occur on battery. When
I'm on AC power, it performs like a champ. I can only assume that
some of power issues that were sorted out in latest power management
driver updates still need some tweaking. From what I am reading
elsewhere on the net, others are experiencing the exact same thing and
it tends to be centered around the speed stepping of the CPU, the SATA
controller, and the Intel Turbo Memory...or some combo thereof...and
all things that change state rather drastically when the system shifts
to running on batter and depending on your power management settings.

Very anxious for Lenovo (or M$FT if it is more a Vista issue) to sort
this out...having a laptop that must always be plugged in to be
functional isn't very functional at all. At least the BSOD'ing has
stopped...
 
Amen...down to the premonition that it is going to hang and the active mouse
when nothing else is dead. I hate to say this, but it makes me feel better
that I am not alone.
