Lenovo ThinkCentre M91p doesn't boot with AMD RX 550

Q: Lenovo ThinkCentre M91p doesn't boot with AMD RX 550

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.

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.)

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.

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

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? Im a noob at all this im sorry ;(All answers are much appreciated, Ajsski99

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.

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.

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 100°C and sometimes more than 200°C, 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.

Hi,

Yesterday I received my Lenovo ThinkCentre Edge E73 and the first thing I did was update my Windows 7 professional. However, after it had rebooted about 3 times it froze on the 'loading windows' screen.

After a reboot, the startup repair launched and was restoring to a previous state. The pc rebooted and tried to do a CHKDSK but it failed and loaded the welcomescreen but froze with the message that winload.exe was damaged. Knowing about the system recovery partition I booted it at start and selected the option to restore the whole pc to factory state. Unfortunately, this happened.

I tried using a retail windows 7 pro-disc to repair the computer since the recovery partition shortcut (f11) didn't work anymore. However, it didn't even recognize that the old windows was there, untill I looked at the partition manager.

It seems the recovery partition is still intact but I can't boot to it anymore. Will it work if i delete the old windows7_os partition or do I have to do anything else? The bios is setup to start from the harddisk.

Thanks in advance,
Joeri

So i tested a 750W power supply in the pc. Still nothing.Then I thought the motherboards BIOS was outdated... Updated it... Still nothing. I even tried updating the firmware of the graphics card. Nothing.The graphics card definitely works because I tested it in my old machine and it worked 100%.However, I took my graphics card to my supplier, and he tested it on another one of his PCs... Didn't work there either.My PC's BIOS doesn't have support for secure boot, in case anyone wants to know.I have run out of ideas now... Any one able to help? 

A:Lenovo M91p Desktop not booting with new graphics ...

There's a white list of graphics cards the BIOS will recognize. The HD 7950 is a 180w card, well in excess of what the factory power supply can provide for (and the case/fans sufficient cooling for), and is not one that Lenovo would provide BIOS support for.

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!

A:ThinkCentre E73 New BIOS doesn't recognize USB HUB...

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

Can I replace power supply and istall video card (Nvidia Geforce gt 730) without any problems ? Beacuse my lenovo motherboard has 14 pin connector and I canat find any power supplies with 14 pin, only 20/24 pin connectors. It is possible to buy new power supply (20 pin) and video card + adapter that will change from 20 pin to 14 pin ? Thanks for answers.
