DELL support answered my inquiry, suggesting to update the BIOS. I had looked for an update, but somehow I missed it on the website. Anyway, since I upgraded the BIOS firmware from v5 to v7 a good week ago, the issue hasn't manifested itself.
If you don't hear from me again in this topic, the issue has been resolved for me. 🙂 HTH
(laptop model E5420)
I tried the bios update also, but that doesn't work. It does seem to reduce the force offs but doesn't solve it.. Dell has replace my motherboard but that didn't fix it either. Seems it is an instability issue that Dell support doesn't know how to resolve this.
I expect them to replace the motherboard until they resolve it.
We have an E6420 that started having the ASF2 force shutoff issue.
It started happening about once every 30 minutes.
I tried everything I could think of before contacting Dell. (swap RAM, swap Drive, different battery, re-image, update BIOS, update drivers, Check BIOS settings).
Dell decided that it was probably the motherboard and sent one out to me. After replacing the motherboard, it was still doing the ASF2 force shutoff.
After thinking about it a while and about what I had seen online when I was trying to figure this out, I decided to remove the wireless card to see if that would take care of it.
The system has been running for over 2 hours now without shutting itself off.
I am going to watch it the rest of the day, and will update this thread either way.
Found out what was causing it. It was the RAM.
The RAM passed the Dell RAM diags as well as HCI memtest.
Put this RAM in another E6420 with the same harware configuration and it started doing the same exact thing as the laptop I was having trouble with.
So I would have to say that this is definitely a RAM problem.
Doesn't matter that it passes the diags, it was still causing the issue.
As soon as I put known good RAM in the laptop, it stopped having problems.
I got a suggestion from Dell.
The Intel AMT conflicts with Broadcoms ASF.. and this will log an ASF2 error.
1) Boot the system, press Ctrl-P to enter the intel AMT Bios
2) Choose Intel ME Management Features, then the ME Management Features Seeting, set Intel AMT to OFF
My problem is on my machine it says "Preparing MEBx menu", and then nothing. I don't get the menu.
I'm having the same problem on a 6530, and the new one they sent me to replace it. In my case it happens every time the 'slice' battery drains to zero, even though the other batteries are still full.
Wireless! Me too: I've been running docked on wired ethernet for a couple months with occaisional wireless undocked meetings, but just traveled and needed remote desktop ("WebEx"/"LiveMeeting" etc.) and BOOM! BOOM! BOOM! Instant surprise sudden abrupt shutdown, just immediate blackout and hard-drive head retraction, no BSOD no warning. It happened four times in an hour, running on charger, on WiFi. For some reason I decided to plug into wall CAT5 RJ45 wired eithernet, and never again for five more days. Then it happed two more times back at hotel, on WiFi -- and again, quit happening when I turned off wireless slide-switch. M4600, W7; Device Manager shows "Intel(R) Centrino(R) Ultimate-N 6300 AGN". Perhaps sudden power demand or current surge causes sudden "crowbar" power supply collapse?
I recently had another laptop, an E6420, that started powering off by itself like somebody was pulling the battery.
The first time I ran the full diags, everything passed. It was only doing it every once in a while so I just left it alone for a couple months.
Then about a week ago, I replaced that laptop with another for the person who was using it. I then ran the full diags again and an error came up for the SSD.
I had Dell send me a new SSD, and so far the laptop is working like it should.
