Vista SP1 killed my system tray icons for wi-fi and battery power

I have an OQO 02 UMPC which came with Vista Ultimate pre-installed.

I had my wi-fi and battery power status icons configured to always show in
the System Tray.

After installing SP1 via automatic updates on May 13, those two items are
gone from my System Tray, and I can't figure out how to get them back.

Help?

Right-click system tray, choose Properties, go to the Notification Area
tab. Check or uncheck what you want to show.

If something is checked but not showing, try unchecking, saving, then
rechecking. You may even need to try a reboot between changes.

Andrew, thanks for trying to help.

I had configured both of these icons to always show, so I meant to imply
that I know how to check for this setting.

I should have specified that now those two items do not show up in the list
of icons that I can show or hide. They are simply gone.

BTW: I have now un-installed SP1 and rebooted, but these two icons are
still unavailable.

I tried looking at the properties of these two devices, hoping to find a
checkbox to expose the icon, but I'm finding no such solution.

On other message boards, I have seen this problem solved by returning to a
restore point, but I had to turn that service off a while back. I forgot to
turn it back on, so a restore point is not available. Another solution
posted is to re-install from my DVD. I will do that as a last resort, but I
can't believe no one knows a registry tweak, or driver upgrade, or some
such...

Searching online some more, I found this helpful link:

I had right-clicked on the Notification Area, and selected "Customize
Notification Icons...". That allows you to configure the display for
everytyhing <except> the four system icons: Clock, Volume, Network, & Power.

However, if you right-click on the Task Bar, select Properties, and then hit
the "Notification Area" tab, you can see the checkboxes for the 4 system
icons. That's the ticket.

Now I feel stupid, but the issue would not have come up, if SP1 had not
changed my settings for those two icons...

Tried this but "Power" is still grayed out.

Till yesterday i had the system icons displaying, mine too are not seen now in the system tray...

Out of four icons in the properties, three are greyed off, only clock is visible....


Can anyone help... its really a problem now...

I hope theres someone to help us out of this problem, is this some virus issue....
