Dealing with Problems (Advanced)
The following phenomena occur
zThe LAN transmission speed slows
down dramatically
zWireless LAN connection drops out
zPoor performance when forwarding
data via a PC card (e.g., unstable
video images when writing videos
to a DV camera using an IEEE1394
PC card)
zThese phenomena may be consequences of performance losses that result
from CPU power-saving functions. Execute the following operations after
logging on with administrator authority.
AInput [c:\util\cpupower\setup.exe] in [start] - [Run], and select [OK].
Follow the on-screen instructions.
BSelect [Performance] in [start] - [Panasonic] - [CPU Idle Setting] and
select [OK], then select [Yes].
The computer will be restarted automatically.
zIf these phenomena occur even with the above settings, select
[start] - [Control Panel] - [Performance and Maintenance] - [Power
Options] - [Power Schemes], select [Always On] from [Power
schemes], and select [OK].
• These operations will be helpful in easing the performance losses resulting
from CPU power saving functions, but will not be effective against the
phenomena resulting from other causes. (e.g., noise generated during
periods of exceptionally high load on the CPU, such as during video
playback).
• When these operations are performed, the battery running time will be
reduced to some extent. We thus recommend that when these phenomena
do not occur, you should select [Battery (Windows XP Standard)] in [CPU Idle
Setting], and return [Power schemes] in [Power Options] to [Portable/Laptop].
Disk Operations
Cannot read/write to a floppy disk zAre you using the Panasonic CF-VFDU03 USB floppy disk drive (optional)?
zHas the floppy disk been correctly inserted?
zHas the floppy disk been correctly formatted?
zYour floppy disk content may be corrupted.
Unable to write to a disk zIs the floppy disk write-protected?
How to format a floppy disk is unclear zFormat the floppy disk using the following procedure.
Select [My Computer] in [start] and select [3 1/2 Floppy (A:)], then select [File]
from the menu and select [Format]. Confirm the disc capacity and the format
type, then select [Start] to begin the formatting.
