ThinkCentre: recommissioned system will not boot from HDD; BIOS, AMT, PXE, M91p

Q: ThinkCentre: recommissioned system will not boot from HDD; BIOS, AMT, PXE, M91p

bought a ThinkCentre M91p, minus the hard drive. The bios rev is 9HKT43AUS and BOOT block is 9H43A
Fitted a blank 2TB hard drive, with the intention of loading LINUX mint. My problem is that the system is still
attempting to boot from a non existing LAN. The original specification inculded PXE V2.1 and AMT 7.1
How Can I return this Unit to boot normally to the HHD. Will upgrading the Bios Acheive this, or must I also
work on the Uefi. Sorry if this seems simple It is causing me a large amount of stress.

Preferred Solution: ThinkCentre: recommissioned system will not boot from HDD; BIOS, AMT, PXE, M91p

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: ThinkCentre: recommissioned system will not boot from HDD; BIOS, AMT, PXE, M91p

I'd recommend going into the UEFI, which replaces the old BIOS standard, and resetting to optimal defaults, which will likely fix the issue. You also should update it, if you have access to a Windows system use rufus to format a bootable dos usb stick and copy the contents of the USB Drive UEFI BIOS Flash Package so you won't need Windows (or a CD) on the actual system to do updates. The current version is 58 vs the 43 you have on there now. By the way you can also use rufus to install Windows to a usb drive for 'Windows To Go' mode which is quite useful at times, especially if you don't want Windows on the system itself. You can download a Windows 10 iso directly from Microsoft's website and via rufus 'Windows To Go' mode isn't limited to just the Enterprise version. CHANGES for 9HKT58A/9HJT58A

I just got a recent AMD Polaris card (RX 550) for Lenovo ThinkCentre M91p, and it simply doesn't boot with it. It doesn't even get to the starting splash screen with Lenovo logo. The monitor remains blank. I updated the BIOS to the last release I could find but it still didn't help. Can anything be done with it? It works with Nvidia cards, but I'm running Linux and want to use open drivers, so AMD is a much better option. I replaced the power supply by the way with better one.

A:ThinkCentre M91p motherboard and ECC RAM??

My question goes like this : On a out-of-warranty ThinkCentre M91p, if we replace the standard CPU (i5) with a socket compatible Xeon CPU, will the motherboard support ECC RAM?

No.  It's the Intel Chipset that interfaces to memory, and only workstation and server Chipsets support ECC.  Check the specs for your desktop Chipset if you like. 
 
Also, just because a processor will fit into the socket, does not mean it will be supported by the BIOS.   Sometimes there is overlap between ThinkCentres and ThinkStations which do use Xeons.   If so, that Thinkstation model will be listed on your BIOS download page, but for unknown reasons that upgrade does not always work.

Hiya, In my current PC I have an i5 3470, and In the Thinkcentre M91p i have recently purchased, it has an i7 2600, which is a little overkill for what ive purhcased it for, so I was thinking of swapping the cpu's so I have the 2600 in my gaming PC and the Thinkcentre gets the 3470.However I'm not sure if this would work as I have no idea whether the motherboard of the ThinkCentre would accept the new Ivy Bridge chip, and I don't even know if my Asus P8H77-V would accept the 2600?So would this work? and how would I go about doing it?

Hello, I recently bought a Thinkcentre m91p desktop. It comes with an Intel Core i5-2400 and a motherboard Lenovo 7052A9G (BIOS 9HKT47AUS - 01/10/2012). What is strange is that the CPU fan runs almost all the time at full speed. I installed HWMonitor and the CPU temperature is normal, but I noticed that one value, the VR temp, is changing all the time and is very high (around 100C and sometimes more than 200C, even at startup). I'm thinking about buying a Zalman Fanmate in order to control manually the CPU fan, but I would like to know if this is a known problem and if there's a solution to fix this. Thanks !

A:ThinkCentre M series M91P Bluetooth

A better way to add Bluetooth to a desktop is with a USB dongle.   
 
Bluetooth is a quickly evolving technology, and to support later devices, you'll need an adapter that supports the latest versions of Bluetooth.    'Newegg' is a good place to look for anything computer related.

Hello, I cannot find the way to install an AMD FirePro v3900 on a ThinkCentre M91p.I need such board for sharing the desktop between two monitors having a DisplayPort and a DVI and don't have enough time to purchase another board. On the M92p, I can use it by going in the BIOS, set the video settings to "PEG" (PCI-e Graphics Device), enable Multi-Monitor support. The cards works and I can later install the driver (coming with AMD Catalyst) to obtain the possibility extending the desktop to two screens. But on the M91p, it does not work : the screen connected to the PCI Express graphic card reports "no signal" no matter if I connect the display with the DVI or the DisplayPort. I also tried setting the video to "IGD" (Internal Graphics Device) or to "Auto" with the graphic card plugged, but connecting the cable to the M91p's native VGA or DisplayPort, with the hope that I could see something and install the driver for the graphic card. But there is no signal to the native ports when the video card is plugged. I also trid using AMD Radeon cards which were working with ThinkCenter M91p or M92p.One with HDMI+DVI works.One with DisplayPort+DVI doesn't.I need a board with DisplayPort (DP) as most of my screens have DP and no HDMI. The drivers are up to date (including the chipset). Only the BIOS was not updated.Should I update it ? Or does the problem have other origin (e.g. power) ? Thank you very much for your help.

Burn a CD with the BIOS ISO, and follow the procedure for recovering from a failed BIOS update in the HMM.   If unsuccessful, do the same with the previous version of BIOS, which is at the very bottom of your system's BIOS download page.

Hi, It appears we are many here to encounter problems with the restrictive white list of graphic cards for the ThinkCentre M91p (as well as M91 and M81) Small Form Factors. I have several AMD graphic cars which work straightforward with the M92p but emit no signal with the M91p. Some will argue that ThinkCenter are business machines and hence the restrictive list of graphic cards.But AMD also produces cards for the business segment, which are assumed being reliable.The white list keeps the M91p away from new cards. I upgraded the BIOS to its latest version, but this did not change anything. Is there a way to stop the filtering done by the BIOS or to upgrade the M91p's BIOS to accept new graphic cards ?What about flashing the BIOS for the M92p on a M91p ?I assume it wouldn't work as the marchines are different, but has anyone tried this ?

When the units attempt connection, it drops to the cabling error message, but the ethernet port is displaying a solid orange led and blinking yellow led as if the cable is connected properly and will work fine once the operating system(Windows 7) is loaded. The issue is not effected by boot order or delaying when ?Enter? is press after the option is chosen.

After a clean Win 7 or Win 10 image is loaded and all the drivers installed and sucessfull reboots I proceed with the Win updates.  After a Win update and rebot Win will not load.  In Win 10 it goes into a diag routine that does not solve the issue no matter what is selected.  I have found that I can get it to finally boot with a Safe boot and then shutdown power off.  After that it will come up. I have reimaged it five times now tryng Win 7 or Win 10 home and professional and all the same results Thank you for any advice Intel Core i5-2400 Processor(3.10 GHz 6 MB)Memory: 2x 8 GB PC3-10600Hard Drive: 1x 2 TB 7200

Hi , I have some Lenovo ThinkCentre M91p dekstops which I try to boot over our network in uefi pxe boot but no luck so far. Our pxe network server is setup to work with uefi only so I set m91p in bios to uefi mode and tryed to boot over pxe but I think network is still in legacy mode, with other type of boot option I have two options to boot ( for example usb flash drive - legacy and uefi boot in submenu to choose in auto bios mode , in uefi bios mode it boot directly in uefi the usb flash drive ) but for the pxe boot its the same in uefi bios option and auto/legacy - connects to network pxe , try to boot and same error for too big size like we get if bios is set to legacy ot cms mode. So my question is it possible to boot in uefi pxe mode this desktop ? Or we will need to change pxe server to allow and working with legacy.Thank you for your answers.

Hello everyone, I have the m91p and recently upgraded some hardware; ram, cpu, and video card. When I first powered it on, it booted fine and I was able to log in. Now when I try to boot it, I get 3 short beeps, followed by 3 long, and ending with 1 short beep. Does anyone know what this beep sequence means? I tried taking out all the new components and replacing with the old and the beeping still occurs. Could this be the power supply?

Hi there, I recently bought a Lenovo Thinkcentre E73 SFF, which had Windows 10 installed in it. I decided that I wanted to installed Windows 7 instead of using Windows 10. I decided to go into the BIOS to change the boot priority so that my Windows 7 installation drive had priority over the pre-existing boot drive. In the process, I also recall disabling "Fast Boot", as the PC kept skipping the post screen every time I booted up. It continued to do that even when I was in Windows 10, but I've now got Windows 7 installed, but I cannot find any way to access the BIOS of the motherboard. Can anybody advise on how I'd go about getting into the motherboard BIOS? TLDR - I've installed Windows 7 in place of Windows 10, but I cannot get into the BIOS as the computer is forever skipping the post screen on bootup. Does anybody know about how I'd be able to get into the motherboard BIOS? Thanks in advance!P.S. I wish you all a Merry Christmas!!!

Hi....... I am hoping that someone may be able to pint me in the right direction.   I have an old IBM Thinkcentre..... I am not sure which exact model it is.  Used to use it in my home office, but moved it out to the entertainment center ages ago and basically use it as a "jukebox" that I have stored all my music into and feed my audio system.  I run nothing else, and it worked fine doing this for years.  Anyway, with a recent update in iTunes, I now am experiencing issues playing back music, as I never have before.   I populated the main board with 4GB of RAM, but when I check in system information...... although it states 4GB installed, it only chows 2.25GB in "total physical memory". I have tried everything I could to increase performance of the resources I have..... disabled what was unnecessary and turned off everything that does not absolutely need to run in the background, but have only improved things a bit.  In doing some research, it was suggested that a  BIOS update "may" allow me to go beyond the RAM limitations of my system.  I figured I would try this out before bagging it and just investing in a new computer. Anyway, I have attached a snapshot of my system configuration.  Can anyone help me find a later version of BIOS?  I have tried searching for it myself, but everything points me back to the Lenovo site, were I cannot find anything.  When I plug in my serial number, it does not find a...

You have a ThinkCentre M50-8189. 4GB max memory.https://www.cnet.com/products/lenovo-thinkcentre-m50-8189-p4-2-4-ghz-monitor-none-series/specs/ Due to the way memory was allocated at that time, the top 1GB of memory is RESERVED.Your BIOS is probably up to date. Other users may have more information to offer about the top 1GB of memory.

Dear fellow community members, I have a huge problem with M83 ThinkCentre. We've bought 80 PCs from a retailer in Germany. All very good condition. These PCs are 2014 release. The problem is their BIOS. It was upgradet to 2016 version and the problem we experience is that whenever we put a GPU in any of the 2 included PCIE ports - it starts, but fails to boot. Same thing on all of them. Do you guys have an idea how to downgrade the BIOS?

A:M83 ThinkCentre BIOS downgrade

What is the model number of M83? Tower, SFF, Tiny?What is your current BIOS level?What graphics card are you trying to use?A link to a website showing graphics card would help (Amazon, Alibaba, etc).

Hello,
I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.
When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part of
the boot menu, Windows 8 starts to boot without difficulties.
How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?
I believe I messed up with boot sector somehow... What needs to be fixed provided that Windows 8 will boot into VHDX file?
Thank you.

Well this is the world we live in And these are the hands we're given...

Hello there, I have (for the first time) a problem with my Lenovo ThinkCentre E73. I recently updated the BIOS (it was one of the initial versions and had some issues) to the latest version. I use a KVM (Keyboard Video Mouse) switch. This KVM switch has some USB inputs (for keyboard, mouse, USB stick or whatever) and the USB part is based on a (switchable) USB HUB. But when i connect my USB keyboard to this HUB, the Lenovo BIOS doesn't recognize it (keyboard does'nt work, and the Lenovo shows error 0211, no keyboard connected. The KVM itself isn't faulty, in Windows everything worked fine. Also the previous used BIOS version has no problems with the KVM and works fine also. There where no changes made in the hardware setup. When i plug my keyboard directly into the Lenovo the BIOS recognized it. When i use a simple (non powered) USB hub and plug my keyboard in, the BIOS doesn't detect is again. So it looks like the new BIOS has some issues with USB hubs. Not only my keyboard would be detected, also USB memory sticks are not visible by the boot manager. Can anybody help me, or can Lenovo made a change to the new BIOS version so i can use my KVM again into the BIOS? Thank you!

I'm curious if you get the same result on a front USB port (I'm assuming the hub was connected to the rear.)

I was trying to resolve the famous problem about the ACPI where the workstation will not power off after system shutdown procedure. I tried flashing again the BIOS but something goes wrong and system got frozen. So I powered off the machine and it never boot up again. I read about some procedure to flash again BIOS when that is already corrupted. I tried burning the iso on a cd and playing with Clear CMOS jumper. Nothing happened. Do someone know how it works for that model?That machina have only cd reader, sd reader and usb ports. So not floppy reader like guides for other models says.
