    I just thought I'd post my experience with this in case anyone else runs into it (looks like it may be unique to me though!)

    My W5F has had the quirk that it will sometimes totally lock-up (which is to say no response to mouse or keyboard, including the WLAN radio switch / power4gear button) a little while - maybe 10 seconds - after resuming from standby.

    It has to be standby, not hibernate - the machine can happily hibernate/resume without issue.

    It makes for a very easy test though. Boot machine, suspend it (I use the F1 key to do it), then tap a key to resume it again. If it survives past 20s or so, its a pass. Otherwise it locks up, and a hard reset gets it going again for hte next attempt.

    Anyway, after one luck-up too many, I did a bit of digging. It turned out that it would only lockup on battery power. Standby/resume on mains power was fine (but in that case, as soon as the mains power lead is pulled out, the machine then locked-up anyway).

    So I tried it with no WLAN: keep WLAN turned off, and theres no problem. Enable it after standby+resume though and it will go right ahead and hang. Thats not really proof though, a lot of applications will behave rather differently if they have an internet connection, so I tried the same test using ethernet. Still no problems.

    So far, so good. Looks like the WLAN is the cause (intel 3945; to this day, I never have seen a good intel WLAN driver, and this one seems to be entirely up to normal standards). Experimentally disabling power management (allow computer to turn off this device...) made no difference.

    Next stop then is to hunt for a new (or old) driver - failing that, a new WLAN card might help (a shame W5Fs have some new-fangled replacement for PCMCIA, otherwise I could try a seperate WLAN card to check things out).

    No such luck for mine - worth a try though. Ditto new WLAN drivers. Good thing this new-fangled technology handles hibernate so quickly :)

    Yeah - it seems to be working (although it did rather weirdly apparently decide for itself to disable WLAN the other night - that was probably my lousy typing snagging the wrong key though :) ).

    You think it might be worth trying wthout it?
