Can't update embedded controller

tried different ways including thinkvantage and everytime update will freeze at the update screen. bios update always succeeds. Any clues?. laptop is T43 1871 came with bios 1.23 and embedded controller 1.03. I was able to update the bios to 1.29 but I was always faced with embedded controller 1.05 update screen freeze problem. my question if bios firmware has to match embedded controller firmware and using thinkvantage update why bios update was listed as recommended and embedded controller update listed as optional? TIA.

I'm having the same problem.
Help!

Correct procedure to update Embedded Controller Programme - T43

Dear Forum,
Could somebody please describe the best way to safely update 'Embedded Controller Programme' in a T43?
- The computer is a Thinkpad T43 1871 PM1 machine
- BIOS Version is 1.29
- Embedded Controller Version is 1.03
- Apparently this is the correct current Embedded Controller Version http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-59439
- Should I boot the machine into safe mode rather than regular startup?
- Should I deactivate my firewall (PCTools), my anti-virus (Avast) and Malwarebytes from running at startup before I shut my machine down?
- Are there any other specific programmes I need to shut down? (eg. IBM Access or any of the IBM updates?)
- Does the controller update require internet access? Or should I also disconnect the computer from the web?
Thank you!! :-)

Hi Harry,
There is no need to boot the machine in Safe Mode, and yes it would be good idea to deactivate your firewall and antivirus products for the time being while the controller program is being updated.
When I run BIOS update, I don't turn off any Thinkvantage tools so in my experience they don't interfere with the update process, and as far as I know the controller program doesn't require internet access (if you're doing manual update from the setup saved on your thinkpad).
Hope it helps.

Should one update Embedded Controller program before a BIOS update ?

Hello All,
I have an IBM Thinkpad 600E 2645 4AU that has an old version of BIOS that am trying to update to the latest.
I read on the net that before updating the BIOS its required to update the Embedded Controller program.
This is what I read and am quoting :
" It is also important to understand that Thinkpads from IBM have two separate firmwares: the BIOS, and the Embedded Controller program. A given BIOS version will require a certain version of the Embedded Controller program. The IBM documentation is sometimes unclear about the order in which these two firmwares should be updated. On most, but not all Thinkpads, the correct update order is Embedded Controller program first, and then the BIOS. Make sure to do the two updates immediately one after the other. Newer models from Lenovo update both the Embedded Controller program and the BIOS at the same time, so you don't have to worry about it."
Could anyone let me know if this applies ? I searched the Lenovo site for a Embedded Controller program for my laptop model but found none. So wondering if this model would require the Embedded Controller program update ?
Thanks.
Alex

OK, I've fixed this now.
I had Kaspersky Internet Security installed and had disabled it manually but it was obvisouly still blocking fundamental system changes like these. I uninstalled KIS completely and then ran these updates again and all worked fine.

Unable to update BIOS or Embedded Controller Program on X40

Hi,
I have an IBM Thinkpad X40 laptop. I currently have BIOS version 1.43 and Embedded Controller Version 1.32. I am trying to upgrade both of these separately using the following programs:
BIOS update (Non-Diskette) - ThinkPad X40
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-53881
Embedded Controller Program (Non-Diskette) - ThinkPad X40
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-53882
I download and run them, go through the 4 step wizard and then the machine reboots. The problem is that it doesn't update the BIOS or the ECP but it also doesn't tell me why or even tell me that it's failed.
Has anyone experienced this issue or know what causes this? I am unable to do this via a diskette because I don't have a floppy drive on this model.
Solved!

How can I update the BIOS without using a CD?

Hello!
I have recently decided to upgrade my RAM from 2GB to 4GB. After installing, I booted up my computer to find that it would not recognize the new memory. After doing a bit of troubleshooting, I decided to try and update the BIOS, as the version was from 2010. I downloaded the BIOS update boot CD application from lenovo, burned a disc, and on reboot I found that the boot order did not have CD listed on it. Here's the catch: I don't have the supervisor password. This is a hand-me-down laptop, and I have tried to find the password to no avail. This is the current boot order: USB drive, Hard drive.
My question is, can I either create a BIOS update disc using a USB, or update the BIOS some other way?
I understand that it is impossible to recover the supervisor password without having it serviced (which I would rather not do, even if I have to send my RAM back to Crucial)
My system specs:
Thinkpad L512
Bios version: 1.04
Bios date: 2010-3-26
Embeded Controller Version: 1.01
Windows 7 32 bit
Thanks for your help.
Solved!

Welcome to the forum!
Two things here:
a) If you run System Update, it should offer the latest BIOS for your machine as well. I've never done it on a passworded unit, so it might or might not work but might be worth a shot.
b) I doubt that the ability of the system to recognize new RAM has anything to do with the BIOS. ThinkPads much older than yours will run 4-8GB RAM with an old BIOS, older than your machine to begin with.
Good luck.
Cheers,
George

G770 on Microsoft ACPI-Compliant Embedded Controller

I have been searching everywhere on the Lenovo support/driver site and on the Internet. I just updated to Windows 8 Pro and have found that my device manager has an alert. It in in other devices, titled under unknown device with a heading of on Microsoft ACPI-Compliant Embedded Controller.
I am trying to find how to fix this. I had the same problem on a Toshiba but somehow I accidentally fix that laptop. But the Lenovo G770 has me stumped.
Please let me know what to do to correct this problem. I saw something about a Trusted Device or so but still can not find anything. I also searched Mircosoft but they tell you to go back to the laptop manufacturer.

CAN'T UPDATE THE BIOS!!

I have a Z60m and i would like to update my bios from version 1.12 to the latest. I downloaded the utility on the website, it says that my laptop should shut down and the restart in update mode but all i see is a regular restart of my laptop and no bios update.
Did anyone had this problem?

You probably need to update the embedded controller to a version that the new BIOS can work with, check the information offered on the download site.
Now, before you ask; I know it says that if you need to update both BIOS and embedded controller you should update the BIOS first, it says the exact opposite on the embedded controller download site - confusing
Just choose your updates and versions carefully.

The embedded controller (EC) did not respond within the specified timeout period - Flex 15D

Hello,
I have an IdeaPad Flex 15D, and I have had several problems (mostly processor-related) in the time I have been using it. I contacted Customer Support twice, and finally did a system reset a few days ago after being told by Lenovo Support that my choices for fixing the problem were 1) Reset, or 2) Pay for a premium service to diagnose the problem. Needless to say (again), I went with option 1. So far I have not had any noticible problems with the processors, but there is a certain error showing up in the Event Viewer that I am concerned about. Lenovo Support has been next-to-useless troubleshooting my problems thus far, so I'm taking them here. The error is as follows:
(Event ID 13)
The embedded controller (EC) did not respond within the specified timeout period. This may indicate that there is an error in the EC hardware or firmware or that the BIOS is accessing the EC incorrectly. You should check with your computer manufacturer for an upgraded BIOS. In some situations, this error may cause the computer to function incorrectly.
Sounds like the BIOS needs an update, right? Well, I went straight to the Flex 15D drivers page, and guess what? I quote the drivers page: Bios update is not required for this product. Not required? So, Lenovo ships a broken BIOS and then refuses to support it? I don't know if Lenovo employees ever read this forum, so this might not be the best way to get their attention, but I am so fed up with Customer Support and I want this issue to be known to more than just a few unhelpful 'tech support' people. The Flex 15D isn't one of the more popular laptops out there, so I can't expect anyone reading this to be able to duplicate this problem or really provide any support, but if you have any suggestions whatsover, please reply to this thread. Like I said, I want people to know, and hopefully we can get Lenovo's attention so they can fix this problem.
Best regards,
Owen Dugmore

Hi,
I understand that you get the error message when performing a full crawl. I have seen similar cases caused by IE proxy settings. You can try to edit the Internet Options>Connections>LAN settings. Uncheck ‘Automatically detect settings’.

Problems directly connecting Windows 7 HP EliteBook to NI PXIe-8135 Embedded Controller

For some reason my computer cannot connect to the NI PXIe-8135 Embedded Controller in my PXIe-1082 chassis. My computer recognizes that there is something there, but it cannot communicate with it (no packets recieved back, but packets sent). I've already checked my firewall settings, network settings, and anything else I could think of that might be preventing me from connecting to it but I have not found a single thing that tells me why I cannot connect.
Any ideas on troubleshooting this problem, or if someone has run into the same problem please let me know - any help is greatly appreciated!
-flynneva

Hi flynneva,
Are you using an ethernet cable to connect to your PC? It sounds like you just want to add this chassis to your network just like any other computer (with the embedded controller is a computer). Here is a link to Microsoft's page on this type of connection in case you haven't tried these options:
http://support.microsoft.com/kb/305621
Also, is this embedded computer running Windows or is it a RT controller? What does your computer do to recognize the connection and what are you using to read the data? Can you ping the IP address of the controller and receive a response?
Thanks!

ACPIEC Embedded Controller error in Event Viewer on XP Partition

So, when in my XP (SP2) partittion I recently started to get hangs when I try to put the system to stand by/hybernation at the blue "preparing to go into Stand by..." screen. It just sits there, locks up and I end up having to reboot. In the XP's Event Viewer I see this ACPIEC error and that seems to be related to the BIOS. But, as we know, I am on a Mac so there is no "BIOS".
It says "The embedded controller (EC) hardware didn't respond within the timeout period. This may indicate an error in the EC hardware or firmware, or possibly a poorly designed BIOS which accesses the EC in an unsafe manner. The EC driver will retry the failed transaction if possible."
So, that is the only error I consistently see in the Event Viewer so I assume it is related, but if I am on a Mac and have no "BIOS" or "EC" how can I source this issue out in XP given it is a partition on my Mac?

Botched Embedded Controller Program Service Utility upgrade.

Hi,
It seems that I might have a little problem. I've recently started updating my T43 with ThinkVantage Update program and the first couple of updates went like a breeze. Even the new BIOS installed alright. But when I started upgrading Embedded Controller Program Service Utility it suddenly stopped at that gray screen saying that the system was now updating and is telling me not to turn it off in any case. The thing is, it says it should take about 30 seconds while I have been waiting for over an hour but to no avail.
I am a little afraid of turning of my computer, don't really want to damage it. Does any of you have any ideas what should I do in such circumstances? Any help would be much appreciated.

with the bios upgrade through windows, the process is quite simple but there is potential for interference from other programs that is going on in the background, this is especially a problem with laptop that have not been maintained properly in terms of regular virus scanning, deleting unwanted programs, keeping background processes to the minimal. For a more secure update, try to do the bios update through the ISO image method.

To update mrp controller through transaction variant

hi experts,
how to create transaction variant for mm02 to update mrp controller,can anyone guide me for the same.
thanks in advance.

if you are using MRP profiles and the field is included in your MRP profile, then you should change it in MMD2 and a batch job will subsequently update all your materials.
If you are not using MRP profiles, then usual mass maintenance transaction for material master is MM17.
Please search the forum before posting basic and redundant questions.

T43p Embedded Controller Upgrade

Dear All,
I upgraded the embedded Controller to 1.06 without pay more attention to BIOS version so the BIOS version was 1.22 and this is uncompatible version between 2 system software.
So now I have a big problem on running, sometimes the Laptop stop on the IBM Screen (Click Blue Button) and can't continue I foreced to turn it off manually then re-run it many times to let it run.
After that I upgraded the BIOS to 1.29 version but I am still getting this problem.
When I am working into Windows XP, 70% of the time the system doesn't work efficently and freeze a little bit but the big Problem when I am trying to run it I rerun it many times to work nice.
My question is; How to uninstall the BIOS and the Embedded Controller?
Regards and thanks

Hello,
The PXI controller can have one of two operating systems:
Windows OS
Real-Time OS (deterministic)

G710 / Win8.1 Pro - missing driver Microsoft ACPI-Compliant Embedded Controller

Just complete installing Win 8.1 Pro on my new G710. I got this message - missing driver Microsoft ACPI-Compliant Embedded Controller. Some users said that it can be solved with "Power Management" Driver but this one doesn't in Win 8.1 list. One user said that PM driver made his computer to slow down. Other users said that it is "Radio switch HW" driver but it is not relevant to G laptop. Any idea what to do?

hi
Yes this is the Detected device for Power Management.
This just allows you to control The system power distribution.
If you don't want to use Lenovo Power Management then that's just absolutely fine.
Windows has its own controls for power.
No need to wory about that ACPI\VEN_VPC&DEV_2004
This is one of my thread where the PM solved it
