I was using a Dell WWAN 5520 for months in my XPS M1330 with Vista 32 SP1. The 5520 worked fine, but the software application (dell mobile broadband card utility) was quite buggy. Due to this and the fact, that Dell isn´t willing to release the firmware upgrade for the 5520 for HSDPA 7,2 Mbs i decided to upgrade to a Dell WWAN 5530.
After some installation problems now the 5530 is running, GPS is working too.
But there is an annoying problem: After hibernation mode the 5530 will not be detected again and there is no way but rebooting to get the card working again ;(
The three entries on the device manager for the 5530 are missing after starting from hibernation. But i don´t think that this problem is caused by a driver or OS problem because of this:
When I go to BIOS menu after starting from hibernation there is "none" shown under "device info" - "cellular device". Already the bios doesn´t recognize the 5530, all the more Vista won´t do. After restarting the machine the 5530 is detected by the BIOS again. Standby-mode is no problem for the 5530 too.
"Cellular device" in the "Wireless" menu of the BIOS is enabled all the time of course.
Resetting the BIOS setting to default after starting from hibernation lets appear the "cellular device" as "installed" again. But it´s no solution for me to reset the BIOS every time after starting from hibernation...
I tried to solve this issue with BIOS A14, A12 an A11. No success. With BIOS A11 the 5530 is not detected at all.
Currently I am back at BIOS A10.
Has anyone ideas oder a solution for this problem?
I was looking at the lenovo site for an alternate driver for the 5530 and noticed that there was a Microsoft Vista patch available to solve the problem where the card would have a yellow exclamation point when returning from sleep or hibernate. Maybe it's related?
I have a solution for you:
Go to BIOS menu (hit F2 several times when the DELL-Screen appears) an then to "POST behaviour" - "boot mode" and select "thorough", then leave BIOS with "Save & Exit".
The Dell 5530 will work now after hibernation too.
Disadvantage: The BIOS-Screen will now appear for one minute or longer until the BIOS check is ready. But just hit "Esc" when the status bar stagnates, and you´ll leave the BIOS-Screen almost quick as before.
But Dell should work at this problem. Neither the 5520 nor the 5530 working proper with several Dell systems. It´s a shame in consideration of the prices of the cards...
Is it actually a Dell 5530 card or some generic version that you bought on the net somewhere?
I know somene who bought a generic version of the Dell 5520 (i.e. the Expedite EU870D) which wouldn't get detected at a cold boot after they updated to the 7.2Mbps firmware upgrade. The solution was to re-flash the WWAN card with the Dell firmware. Since then it seems to be working fine....
Well if the 5520 card worked fine then it's not a fault with the laptop.
Try flash the 5530 card with the latest firmware - if that doesn't work then try the card in a laptop that it was intended for. You could also try another 5530 card in your laptop. It might just be that 5530 card isn't compatible with the XPS M1330. As you already know, Dell try to prevent you using it by blocking the driver installer.
Other options might be to upgrade the 5520 card to 7.2Mbps (not that you will realise that speed anyway) and set the card to "ndis" mode. That way you can avoid using Dell's BB utility.
I talked several times to the Dell support. The 5530 is compatible with the XPS M 1330.
My 5530 has the Modem Version R1B/1. At the Dell support website i can´t find any firmware for the 5530.
