X301 Win7 x64 Ericsson F3507G WWAN issues

[farzan]

A lot of posts on this topic...

Context:

fresh Win7 x64 install on Thinkpad X301 4057-WBR. All downloads & drivers applied. All devices visible and working properly according to device manager. All prereqs for AT&T WWAN HSPA driver installed, except KB948278 as this is a patch for Vista - not Win7.

Problem:

Fn+F5 shows WIFI and BLUETOOTH but not WWAN radio. Immediately after reinstalling hotkey driver, or chipset driver, WWAN radio is visible and powered off. Pressing Power on does nothing. Press Fn+F5 again and WWAN radio is gone.

Conclusion: unable to power on Ericsson F3507G device when running Win7 x64. Device was working perfectly under Vista. A patch is urgently needed - I'm sure I'm not alone on this one.

Reading other posts on same topic:

- BIOS reset to defaults does nothing. All ports/devices are already enabled.

- Installing Ericsson MD400 modem driver which includes Wireless Manager does nothing. Device not detected.

Seriously, this is the only reason I got this laptop to begin with - and now it's the only thing not working.

Thanks for feedback. Here's my status:

I installed system update 4.0 which made it a lot easier manage drivers etc. I have also manually uninstalled the power manager application, but unfortunately this does not help. Here's what happens with/without power manager:

1) after boot, all three radio icons above F6-F7 are on

2) hitting Fn+F5 shows wifi on, bluetooth on, and wwan off

3) clicking power on for wwan does nothing (some hdd acivity), window closes

4) repeat steps 2-3 and wwan status changes to "disabled"

5) hit Fn+F5 again and wwan radio is gone. Repeat.

Suggestions? This laptop is heading for early retiement...
