BIOS //& Lenovo Battery Firmware Update Utility Dependency Wrapper

Hallo zusammen,
ich besitze folgendes Modell und benötige eure Hilfe:
(hier noch einmal die genauen Spezifikationen:
Turion K685(1.8GHz) 6GB RAM 250GB 7200rpm HD 13.3in 1366x768 LCD ATI Radeon HD 4225 802.11bgn wireless Bluetooth 1Gb Ethernet UltraNav 6c Li-Ion No preload)
Ich habe folgendes Problem, das sich als eher umfangreich gestaltet; ich hoffe dennoch, dass mir jemand helfen kann & dies auch tun wird:
Aufgrund der sehr kurze Laufzeit des Akkus (trotz guter Pflege) bin ich zur Update Utility (s. Betreff) gelangt und wollte das Update durchführen. Die Seriennummer meines Akkus habe ich selbstverständlich im README for the Battery Firmware Update dependency wrapper utilities abgeglichen und sie sind dort auch aufgeführt.
Bei der Durchführung des Updates kommt folgende Fehlermeldung:
Ein Update des Power Managements konnte ich durchführen, aber es scheitert an der aktuellen BIOS-Version. Laut READ ME wird als Minimum die BIOS-Version 1.18 (6ZET31WW) benötigt, ich habe Version 1.17 (85ET44WW) und auf der lenovo-Seite auch nur die Version 1.25 finden.
Ich habe vor einiger Zeit einmal mit einem Techniker telefoniert, der alle meine Daten geprüft hat und mir einen Link zum Firmware-Update des BIOS (File mit dem Namen "6yuj11us") gegeben hat:
Dieses wollte ich dann durchführen und es hat auch so weit funktioniert:
Beim Klick auf "Next" kommt es dann aber sowohl beim Update des BIOS, als auch der "model number" zu folgender Fehlermeldung:
Wenn ich dann im DRIVERS-Ordner in das erstellte Verzeichnis navigiere, finde ich WinPhlash (32 & 64), da traue ich mich aber nicht so recht weiter:
Den Support kann ich nicht befragen, da meineGarantie abgelaufen ist und ich hoffe an dieser Stelle nun auf eure Hilfe. Hat das jemand schon einmal durchgeführt oder kann mir sagen, dass das (sogar im Falle eines BIOS-Updates) bedenkenlos ist?
Vielen Dank schon einmal im Voraus!

Von so einem Quatsch, den der so genannte Techniker angeraten hat, würde ich auf jedem Fall absehen. Auf der Supportseite von Lenovo ist eindeutig zu entnehmen, dass die BIOS Versionen 1.25/1.20 aus dem Jahr 2012 und die 1.15/1.17 aus dem Jahr 2013 stammen. Ich denke, dass es sich um unterschiedliche Geräte handelt und entsprechend eine bestimmte BIOS Reihe unterstützt wird.
Im Readme steht:
Versions 1.25 (for BIOS ID 6Zxxxxxx-based computer)
1.20 (for BIOS ID 6Yxxxxxx-based computer)
und
Versions 1.15 (for Machine types: 0217 and 0250)
1.17 (for Machine type: 0221)
Ich denke, dass ich mit meiner Vermutung richtig liege.
Wo du eine BIOS Version 1.18 beziehen kannst, das weiß ich nicht. Vermutlich gibt es keine neuere Version. Ich würde auch nicht krampfhaft probieren eine falsche aufzuspielen.
Meine Frage ist, wie lange die Akku, so im Normalbetrieb reicht?

Information: Update BIOS and Battery Firmware to ensure full charge capacity

Is your system’s BIOS and battery firmware updated to the latest level?
If not, you may not be getting the maximum capacity and run time from your battery!
Lenovo’s engineering team released updated BIOS and battery firmware in July that is applicable to customers who have ThinkPad models:
X100e, L410/L510, L412/L512, SL410/SL510, T410/T410i, T510,T510i, W510 or ThinkPad Edge, 13, 14, or 15 inch units.
Customers who use Lenovo ThinkVantage Toolbox would have received a notification and opportunity to apply this update, and Lenovo’s ThinkVantage System Update tool would also identify and apply these updates.
If you aren’t using either of these tools, and have one of the systems above, please follow this link to our support site. You can learn more there, and download and install the updates specific to your system.
Probably also worth mentioning, is an earlier tip applicable to X200t and X201t tablet users who have 8 cell extended batteries. This technical tip and related BIOS updates ensure these batteries properly charge to their full capacities, and resolves a particular symptom where the battery would stop charging at less than 50%.
Source Lenovo Blogs: Update BIOS and Battery Firmware to ensure full charge capacity
Recommendation before updating bios:
- detach all devices from you system
- undock your system, if docked
- start from a cold boot. (shutting down the system completely, wait 15 min, start up again)
- if possible, upgrade with a cd-rom drive
Edit: Recommendation added.

TIP: If your computer runs satisfactorily now, it may not be necessary to update the system.

How old is your Mac computer? If it is 2+ year old or older you need a new battery. Right there in what you posted is says "Service Battery". That means Change the battery.

Disk Image for Firmware Update Utility for LaserJet p2055dn is corrupted

Yep. Not sure what happened with that one. I have submitted the issue to the software team. Hopefully I can get a copy that works out to you soon. Apologies for the inconvenience.

Update to my previous post: HP confirms that their Firmware Update Utility is broken, but there is another way to update the firmware on a LaserJet P2055dn using a Mac running OS X, and here it is. HP tech support walked me through this procedure and it worked for me: Getting the printer ready: ensure that the LaserJet P2055dn is connected to your computer and make it the default printer. In System Preferences / Printers and Scanners, find your HP LaserJet P2055dn, select it, Click “Open Print Queue” and on the Printer menu, choose “Make Default.” On that same menu, choose “Print Test Page” and verify that the page prints.Using your Web browser, go to the following page on the HP website and click the “Download” button. Don’t worry that the page says it’s for Windows Vista. The file you’re about to download is for your HP LaserJet printer and doesn’t care what kind of computer you use to install it. Here’s the link:
http://h20564.www2.hp.com/hpsc/swd/public/detail?swItemId=ja-143142-1#tab1
When it finishes downloading, go to your downloads folder and find the file HP_LaserJet_P2055dn_20141201_build155964.rfu
(note: you'll probably get a “Preparing for HP separation” message;. Just click OK)In your Applications/Utilities folder, find Terminal, and open it. In the Terminal window, type lp (space) but don’t press “return” yet. Drag and drop the above file from your finder window into the Terminal window. Then press “return”Watch the LCD display on your printer. It should go through several steps, beginning with “erasing” and finally saying “ready.”Go back to the printer’s “Print Queue” window and print another test page. If the test page prints properly, congratulations. You've done it!

T410 battery firmware update fails

Hello,
Yesterday my ThinkVantage Toolbox offered me to update my battery firmware because of some critical issue. When I pressed on "Update now" it directed me to here. I downloaded a file for my T410 (type: 2537-22G) however, when I try to install it, it fails with a message "The tool was unable to update the battery firmware due to an internal error". It does not work even when computer is restarted and the updater loaded right after the login. I tried reruning the application a lot of times, but nothing helped.
Additional information:
HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\BFU\DependencyWrapper\ReturnCode = fffffffb (So I pressume, that it is not able to get a current BIOS version, however the value of BIOS_Version in the same key is 1.28.)
My boot loader is Gnome 1.98
I use Windows 7 and among other programs there is Skype (4.2.0.169), Comodo Firewall (4.1.150439.920) and avast! Free antivirus (5.0.594, virus definition 100817-1), however I tried turning those programs of and disabling antivirus, but it did not help.
Two screenshots:
Before installing the update.
Failed instalation of the update.
Can anybody please help me?

Has anyone sorted this out? I'm having the same problem with my T410.

Firmware Update for Yoga 11

Hi all,
I thought I would inform you all that my Yoga 11 (Windows RT) had just received a firmware update via Windows Update.
Please, see the details below:
System Firmware Update - ‎15.‎10.‎2013
Installation date: ‎16.‎10.‎2013 20:11
Installation status: Succeeded
Update type: Important
These updates are released by PC manufacturers to help improve the stability and performance of PC hardware.
Prior to the installation Windows Update showed a warning that the battery should be charged before rebooting.
Machine rebooted, firmware updated, all went fine. I just wonder what changes/improvements were made by Lenovo.
Has anyone got an idea? Can Lenovo comment here maybe? Thanks! (I suspect that it has to do with the coming Windows RT 8.1 Update.)

Hi,
The firmware update utility does not support wireless connection, it only allow updating the firmware via USB as written on its installation instructions:
The HP OfficeJet 4620 series printer Firmware flashing (upgrade) requires a wired network or a USB connection.
DO NOT upgrade the printer firmware in a wirelessly connected printer.
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=mp-104396-5&cc=us&dlc=en&lc=en&os=4063&productOid=5101234&sw_lang=
Try updating the firmware wirelessly as following:
On your computer open the HP Officejet 4620 software and click the Printer Home Page (EWS) option.
From the displayed EWS page open teh Web Services tab, then click on Product Update and follow the steps on screen (enable Web Services if it disabled)
Follow the steps on screen to update the printer.
If the process fails, temporary connect a USB to the printer and then launch teh firmware update utility once again.

@lalit_205
If you have a valid warranty you could go to a Lenovo service center to update the phone or flash/install (at own risk) the latest S062 update.
If you decide to flash the latest firmware->
Download and unpack the latest S062 firmware and follow the installation instructions from Message 2(refers to a different model but the driver and flashing procedure is similar.The S660 battery is removable....You do need to remove the battery to install the vcom/sp driver.Also the firmware installation is done with the battery removed in the S660 case).
I suggest to select ''Firmware Upgrade'' instead of ''Download Only''(DO NOT SELECT ''Format All + Download).
Alternative instructions link.
Hope this helps.

Megastick 256 firmware update failure (USB 2.0 version)

When I update the firmware of my Megastick 256 (the new "silver" USB 2.0 version), it would not turn on anymore and seems completely dead. I can "revive" it by removing the battery and connecting it while the "Play" button is pressed and "downgrade" to the firmware version from the included CD (version 2.000.008). I would like to update to 2.011.002, 2.100.000 or 3.000.013, but all of them turn the stick into a dead brick. My computer only has USB 1.1, but I don't think this is the problem.
Ths update utility tells me that my stick has "chip version" 3500.
Another problem is that the firmware update utility will report a timeout when I connect the stick with pressed "Play" button, and the firmware version present in the "msi-5112" directory is not 2.000.008. I can only update by connecting the stick normally.
Has anyone managed to update the firmware of the new revision of the Megastick? If so, how exactly did you go about it?
Thanks in advance

- Do you also have the USB 2.0 version of the stick?
it is usb 1.1
- Does your computer support USB 2.0?
yes
- How exactly did you do the update (when did you press "Play"?).
Held play down,plugged into computer, kept holding play
until recover device was visible.
Copied and unzipped the new firmware to c:Program Files\MSI\MSI551X
Ran the program START->Programs ->MSI->MS 551X Update
Check the update firmware was 3.xxx and click Start or Okay.
waited for it to finish. unplugged mega stick and powered it on.
- What was the original firmware of you stick?
2.11.2
- Did you use the update program from the CD or the one from the MSI page?
from the cd
- Did you have the battery in the stick for the update?
yes.

HP LaserJet 1518ni - Firmware update doesn't do anything

Hello folks
I am trying to update my HP LaserJet 1518ni to the latest Firmware (2013-11-08 , Version20130923, 4.22M).
My current firmware datecode is: 20120110
I went here: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?cc=us&lc=en&dlc=en&product=3422472
Downloaded the file CP1510_Series_FW_Update-20130923.exe
Turned Firewall and AntVirus OFF, ran the Executable with administrative priviliges - it says it found the printer and I see a progress bar and also the smiley at the end. But the printer is unimpressed and shows just "Ready" in the LCD, nothing changed: The files does simply nothing.
Tried it via IP Port and also USB on another PC, same effect.
What is going wrong?
Where are the good old .RFU Files I just can TFTP to the printer...?
Thanks,
Thomas
This question was solved.

Hello @TomPe , and welcome to the HP Forums!
I see you're experiencing firmware issues. I'd like to help!
I would recommend performing a power reset on the printer. Disconnect the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug the printer back in. Ensure you plug the printer directly to a wall outlet. Make sure to bypass any sort of surge protector or power bar.
I would then suggest downloading and running the HP Print and Scan Doctor.
Once you have run the doctor, try installing the firmware via this tool:
HP Color LaserJet Printer Firmware Update Utility
Also, can you print standalone? I would recommend pressing the right arrow until you see reports, press OK, select diagnostics page, and press OK.
Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums!

Megastick 520 Firmware Update Error

I tried to update my MS-520 firmware (version 0.1.7 to 0.1.9) but for my surprise the UPDATE PROGRAM detect the files I had downloaded (tagged MS520 0.1.9) as MS511 , ¿Can someone in MSI explain that? Of course my MS520 became unusable but afterwards I put it again to work using the Recovery Mode. The case is, ¿IS MSI DOING THINGS CONCIOUSLY?
Another point, ¿IS POSSIBLE TO UPDATE THE MS520 INTERNAL DATE? The files I recorded were tagged in 1997 or something like that...
The functionality of the MS520 is EXCELLENT but not the SUPPORT FROM MSI which must be performed in a better way not to lose customer confidence.
If anyone can help me solve these doubts...
Thanks.

Laserjet 1525nw firmware update for macintosh

Printer HP LaserJet 1525 NW
OS Mac OSX Lion 10.7.2
I received an email from HP saying I needed to upgrade the firmware. I downloaded and ran the Mac installer. It crashes when it tries to download the firmware update from the internet. There is no explicit description of the error - the installer simply crashes. What am I supposed to do? I have tried repeatedly downloading the intaller in case the first copy was corrupt. The crash takes place consistently at the same point in the firmware installation process.
This question was solved.

You could try download directly from here to some removable media on another machine (in case your mac is acting up)? http://ftp.hp.com/pub/softlib/software12/COL34888/lj-86474-6/CP1520_Series_FW_Update-20111215.dmg
The above firmware update utility is for the HP Color LaserJet Pro CP1520 series.
This utility is for use on Mac OS X 10.5, Mac OS X 10.6, Mac OS X.
The utility can be used with a USB connection or network connection. Be sure to use the firmware update utility that is specific to you printer model.
This update is recommended for HP Color LaserJet Pro CP1520 series that has a firmware version prior to 20110329.
This utility updates the printer firmware version to 20110329 (March 29, 2011).
The firmware version can be found from "Setup Menu" -> "Service" -> "Firmware Datecode".
