Normally the system is very responsive: UserBenchmark rates it PC Performing above expectations (60th percentile).
Unfortunately, bout every 4th to 6th time my Z640 returns from sleep It is running painfully slow.
By painfully slow I mean response to mouse clicks or mouse window drags is usually 5 or 6 seconds!
Keystroke and <CR> response is similarly slow!!!
To recover I either put it to sleep & wake it again, or reboot either of these has always worked.

An update: I left Task Manager's performance window open. When the Z640 came up very slow the CPU CLOCK SPEED was reported as 1.28 GHz! After a sleep cycle it displayed as 2.5 GHz.
Is there a way to increase the clock speed up to normal without rebooting or sleep cycling?
