Q: M91p doesn't 100% turn off & CPU upgrade question

Hello,I've M91p, i5 2400 - Win 10 64 bit.3GB RAM.BIOS Version - 9HKT43AUS. After I shutdown the computer, the power led doesn't turn off (like in the picture below))? And after that I can't turn on my PC until I make hard shutdown (press the power button for 7 sec).thats happen every time I shutdown my PC.What can I do about it?And I read about the problem of freezing - twice a week I have that issue too.I know that's because of unsupported CPU with Win 10. There is something to do about it?a CPU upgrade will help? Or BIOS update? (-If I'll need to update my BIOS - is there some guide in this website to help me do that?) THANKS!!!!

Hi,after installing the Windows 10 fall creators update 2017 (1709), my M91p doesn't wake up from sleep any more. Before the upgrade it worked fine. Now I have to shut it down the hard way and restart - then it will continue at the point where I left off. Any ideas on that?Best regards,Sebastian

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.

Hi everyone,Ever since I've updated my laptop to windows 10 its has 2 problems that I can't seem to fix.1.

Then to turn it off completely I have to keep my finger on the power button to turn it off properly.2. When my laptop go's into standby mode it will not wake up so I am forced to do a hard reset.Is there anyway around this issue and if so how can I get this sorted out.Kind regardsAmir

Hi everyone, I recently acquired a M91p SFF with:i5-24008gb RamAsus eah5450 low profile passOptical drive500gb hdd @7200rpmand 240w PSU So I have been researching a lot about what GPUs will work in my systemI decided to buy the GT730 (to upgrade my old gpu).It has a power consumption of 25w (TDP of 38w) according to the geforce website.I just want to make sure that it will work.Although I am confident it will work because the asus eah5450 has a power consumption of up to 75 watts.I MAY have to update my bios but my concern is that there's no bios update for Windows 10.I am also planning to transfer it to another case and buy a new psu but I am not sure what size the motherboard is (most likely micro-atx) and also the connectors to a new psu would be similar to the stock psu that I currently have The GT730 is on it's way and i'm planning to install it and removing the power to the optical drive (dvd) since I don't use it that often. This is just to make sure that my psu would hold the entire setup. Any suggestions guys?Thanks!

I recently bought a Thinkcentre SFF M91p and tried to install an AMD Radeon HD7570 with NO success.  The machine will not boot.  The CPU and GPU fans spin, but it never boots.  I thought first it might be a power issue, and tried unplugging the CD-ROM drive, which didn't work either.  I then moved to upgrading the BIOS and that also had no effect.  I did find this morning the PCI-e slot in this machine is listed as a 2.0 slot and the HD7570 is spec'd at PCI-e 2.1, so is this card completely incompatible with the M91p I have? What GPU should I be using that will work straight away, and give me the max performance in this system without having to upgrade the PSU?   The system specs are as follows System type:   M91p, SFFSystem model number: 4518Y4DOperating system installed: Win10 Home 64-BitBIOS version: LENOVO 9HKT58AUS, 6/10/2014Thank you for your help!

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

Hello alli recently upgraded my i7 m91p from 4 gigs ram to 16, the max allowed on my machine. However only 2.8 are usuable, I've been told it's because I'm running 32 bit os, and need to clean install a 64 bit. How would I know if I can install 64, technically if 32 bit only supports 4 gigs and this machine is upgrade able to 16 gigs ram doesn't that mean it will run 64 bit.. How else would it see the ram in 32 bit. Thank you so much

Hi,I recently got my hands on a M91p SFF with:i5-2400 CPU8gb Ram250gb hdd @7200rpm2 tb hdd @5400rpmand 240w PSU What I want to do is to convert this machine into a [email protected] / 1080p gaming machine. My plan is to buy the MSI 1050ti lp and even though it seems to run on the 240w PSU I feel that I want to upgrade it to at least 300w to be safe and so that I can upgrade the ram to 16gb and maybe add an extra fan and a usb hub in the front, where the optical drive used to be, so that I can connect more than just two USB gamepads in the front.After some goggling I found this power supply: http://www.bequiet.com/en/powersupply/496 According to my measurements, is should fit. But I want to be sure, will this work in the case?Also, I think I read somewhere that Lenovo does not a use standard ATX connection, but from what I can see, this system uses a standard 24 pin ATX connection to the motherboard. I might be wrong though. I am no expert on computers and I have never upgraded or built a system before so I ask here to be 100% before I buy anything.  I hope someone where can shed some light on my situation. Thanks

Hi. I just purchased a Lenovo Thinkcentre M91p (machine type 0266) which has an external 150w power supply. I purchased it to be used as a HTPC and i want to put a gpu and more ram in it. The problem is the power supply, all the ones i see people talk about have an internal 240w power supply. On the back of the pc is a DC in jack thats directly into the motherboard itself. I ran some calculations on power usage and the site i used said the recommended power supply size for the standard unit is 150w with a peak load of 123w. Adding the gpu alone pushes the peak load to 140w (nvidia gt730) with a recommended supply of 180w. My question basically is how can i upgrade an external power supply when all i can find is standard 150w external replacements or internal ones that wont be of any use

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 ?

I could even possibly use an adapter to make the correct ending. i dont see why this wouldnt work as the power supply is all external

I have a bit of a strange issue with my computer. Forgive me if I'm a little too descriptive, but I'm not sure which details are relevant and which are not for such a problem. First, the specs:

Model: eMachines T2984
Operating System: Windows XP Service Pack 2
Processor: Intel Celeron D Processor 340, 2.93 GHZ, 256K L2 Cache, 533 MHZ FSB
Power Supply Unit: Bestec Model: ATX-250-12E REV: P7
Motherboard: I can't tell, but it appears to be an Intel motherboard by the number of Intel labels on it
RAM: 512 MB DDR SD originally, added 1 GB a couple of months ago
Let me know if you need anything else...

Yesterday, I got home from shopping around 1PM, and I tried to start the computer. I pushed the power button, and nothing happened. I checked all of the cords, and they were all plugged in. Not knowing what else to do, I opened up the case to see if there was something obviously wrong. The only thing that I noticed (other than a bunch of dust) was that the power supply unit was still hot. I shut the computer down about 5 hours earlier after about 20 minutes of use, so it seemed strange that the power supply was still hot. I unplugged the computer just in case there was some sort of fire hazard.

At this point, I called a friend who suggested that the problem might be with the motherboard or the power supply unit.

A few hours later, I plugged it back in to try to get it to work. As soon as I plugged it in, the entire unit suddenly started "running" by itsel... Read more

A:Computer Doesn't Turn on, Fans and Some Lights Turn on Automatically

I would suspect that the Power Supply Unit (PSU) is going south. If you have a spare one laying around, install it and see if the problem goes away.
You can buy a new,better PSU from Newegg for about $40.00. I have used a Thermaltake 430 watt in one of my machines for some time now and it works well.
You will have to check the size of your PSU to be sure a new one will fit into the eMachine.
Here's the page with that PSU on it. It's the last one on the list.

Hello TSG,

My girlfriend is having a few difficulties with her 500GB Buffalo External Hard Drive. As of this morning, her Laptop hasn't been able to turn on if the HDD is plugged in, and if she plugs the HDD in while turned on the Laptop doesn't recognise it and Blue Screens after a few minutes.

She hasn't had the Hard Drive long (coming up to a year now) and her Laptop is a Fujitsu Siemens with Windows 7 OS.

She says she doesn't want to reformat (though it sounds more of a power issue to me) if possible, as she has a lot of photographs and work on there she doesn't wish to loose.

If anyone has any idea what's wrong, please let us know!

Thanks a lot!

I just advised her to try plugging the EXT HDD into another plug socket, and low and behold it works again. She said however that when she plugged it in, blue sparks flickered at the socket for a few seconds, which really doesn't sound good...

Any idea if it's the HDD's plug itself going... or is it the sockets in her room? <_> Cheers.

I just put together my first computer 6 months ago. It abruply shutdow in the middle of writing a paper for school. I couldn't turn it back on right away. after trying a few times, it turned on. All the fans are working even the fan on the power supply, the motherboards lights are on. My graphic card in on the motherboard. I think it might be my power supply because when I first put it together I didn't plug in the smaller power connection to the motherboard and the same thing is happening, black screen. It's like my computer isn't giving my monitor any feed. I will have more info when I get home. I can't get in to bios or safe mode.

This is my problem: I have the power saving settings set to turn off my monitor after 20 min. It does briefly turn off, only to turn on again 1 sec. later, displaying a faint very dark blue screen... It used turn off fine, but after upgrading from Windows 98SE to XP Pro I got this problem. Is this the OS or my video card?

Any clues?

Thanks all

A:"Turn monitor off" setting doesn't really turn off

Did you upgrade to XP right over the top of 98 or was it a clean install? If you did an upgrade over the top of 98 (and I know you don't want to hear this lol) then you should format and do a clean install. Upgrades rarely leave you with a stable system.

Things to try before you do that though:

1) Make sure your video card drivers are up to date.

2) Make sure Windows is updated - go to windowsupdate

3) try the system file checker (Start, Run, "sfc /scannow" [without the quotes]) to make sure your system files are intact.

Other than that I would say just do a format and install XP from scratch (to be honest, you should do this anyway if you haven't already, you'll get much better stability and performance).

A:PC doesn't turn on

Are you sure the wall outlet still has power? Did you try to plug a lamp into the outlet to check for power? If your PSU isn't plugged directly into a wall outlet then please make that happens.

Often a computer can break and still remain functional until power is removed. Once the power is gone the broken circuit can/will no longer function. The power button on your computer case could be broken or simply have a lose wire. All the power button does is briefly short the connection. When you push the power button the motherboard will sense the short and turn on. You can check the power button's connection by briefly shorting the two wires that connect the power button to the motherboard at the header.

Okay so by default, the HDD turns off after 20 min of inactivity. It's too short and gets annoying having to wait for the HDD to spin up every time I want to search the drive for something.

So I set it to 60 min. But it doesn't turn off after 60 min. I go to sleep and when I wake up and use the HDD, there's no spin up cause it's continuously spinning.

The power option works for 20 min but not for 60 min it seems. Anyone know how to get the power saving option to work?

A:HDD doesn't turn off

Hello Cyborg,

You may have something (ex: program or Windows 7) that is accessing the HDD for something within that 60 mins that causes the timer to reset. You might see if decreasing the turn off time by 5 minutes at a time and testing inbetween to see which time it works at.

Hope this helps,

Hi there!
I have had my rig for about 1 1/2 years now, and I have upgraded the graphics card and power supply about half a year ago. But for the past few days I've encountered a problem that the pc doesn't turn on with the first try.

My pc case has a blue light for indicating power supply, and a red one for HDD activity. When I press the power up button, sometimes the red light doesn't turn on and only the fans spin. Also the startup screen doesn't appear. I've had a faulty power supply before and it had similar symptoms, but this time I assume it most certainly is not the power supply to blame, because whenever the computer does start, it works flawlessly, and doesn't shut down or stutter during gaming on 3d rendering.

What could cause this problem? Could it be the power button itself? I guess I will open up the computer over the weekend and try to look for a loose wire or smth, but maybe someone has encountered a similar problem and knows where to start?

A:PC sometimes doesn't turn on

Firstly we have no idea what the specs are of the system in question, so can be difficult to make any informed response. Please post some detailed system specs including make and model of the motherboard, CPU, RAM, graphics card, power supply etc. The more info the better.

Based on the symptoms I certainly wouldn't rule out a faulty PSU.

It wouldn't hurt to double check all cables and connectors inside the machine.

But on Tues. evening the same problem happened again, so I tried to reboot my modem twice - w/ no luck w/ my pc. I called up Qwest support, explained my problem, and was told this is not a modem issue (my modem is from Qwest), but my pc. Luckily, when talking to Qwest support, I was able to turn on my pc...and when I finally got in touch w/ someone at eMachines (maker of my pc), I was told that it sounded like a software problem.

Hello --
I've got a Dell Inspiron 6000 laptop, it's about 4-5 years old. I'm not very tech savvy.

A weird thing started happening recently:

Whenever the computer shuts down (Standby, hibernate, or full shut down), either b/c I power it down or just b/c I close the lid, the computer refuses to turn on again.

When I press the power button, the fan starts up, the power light comes on, the caps lock light blinks 9 times and then it turns off again. Happens regardless whether the laptop is plugged in or on battery.

I have discovered that I can get the computer to start up by holding down the "play/pause" button bellow the touchpad and pressing a bunch of keys on the keyboard simultaneously. This causes the computer to turn on and opens a program called Dell Media Experience (which I've only used occassionally before). But this "solution" is not reliable and seems to be getting less and less effective(the first time, I just pressed the button, since then I've had no success unless I also hammer the keyboard a bit).

At this point, I'm afraid to let my laptop sleep or turn off for fear that it will never turn back on.

Anyone have any idea what the problem is? PSU? Motherboard? Something easy to fix that a non-techie like myself is just unaware of?

Plz let me know ASAP.

However now the MoBo lights up and thats it, I tried pressing power button multiple times but nothing.

The problem sounds like the power supply, if not that, then the motherboard. A good way to narrow the problem down, would be to swap a known working power supply, and see if the computer boots up. If it doesn't, there is a problem with the motherboard (considering all wires and cord are connected properly and there are no other power issues such as AC outlet, surge protector, bad PSU power cable etc.)

HI.I was trying to install a new Hdd on my HP 15-d038dx but it wont start up, what I mean is when I press the on button it keeps the screen black (no backlight) so it doesn't show BIOS screen, no fan sound, no capslock/numlock light and no power on light. it's like I have never pressed the power on button (I tried to remove the battery and ac power adapter, press the on button for 30 sec. without changes )but when I install the old HDD it starts normally, by the way it starts without HDD tooit just happen when I plug the new HDD ( I tried with a seagate and western digital)

With regards to your problem, that is a pretty bad way to turn off a pc it could be that your power supply has broken, take a look through this thread to make sure, either that or the motherboard or cpu could be damaged from the power suddenly disappearing.

Okay I've had my laptop for about 5 months and out of no where it doesn't turn on?! What's going on I didn't pay all that money for a "good" brand company to do this. I plug it in and not even the little light near the charger port turns on.

It is quite possible the AC adapter has gone bad. If you are still under warranty you should open a support case with HP or if you have an amazon account you can get a replacement AC adapter quickly for testing purposes.  http://www.amazon.com/HP-ENVY-x360-Adapter-Premium/dp/B00OJU6BEQ I am going to guess this answer is not going to make you happy but we are a user to user forum and have no ability to make warranty adjustments. You could also try to find an electronics shop that would test your adapter on a voltage meter to see if it is putting out power.

Hello everyone!! (I think I'm the only one here though on a Saturday night )

Anyway, I've been reading through the forum to see if I could find some answers to my problem with my HP and the closest one is "Old School" dated September 1, 2006. So, I've noted some of the answers and I'm going to try some things (that apply) tonight with my computer.

However, the initial problem started when I began to notice my computer slowing down, so I decided to remove some programs, files that I no longer needed. Afterwards, it didn't seem like it help any at all. A few days after that I began to get errors saying the memory was low and so I decided to completely start all over, going back to when I bought the computer new. However, when I attempted to do this it wouldn't let me saying the memory was low or not enough memory. Next thing I knew my computer completely crashed and I haven't been able to get it back on. Here are some of the things that are coming up when I try to start it.

1. Stop: c000021a {FATAL SYSTEM ERROR}
The session manager initialization system process

I work on it the night before and it was working perfect. It had 50% of battery when I turned it off. Today I tried to turn it on but it didn't. I tried to charge it but even if the charging indicator light is red it doesn't turn on. It seems to be dead. What can I do?

So my old laptop started shutting off without notice when unplugged. When I plugged it in it worked fine. After a while it didn't turn on even if it was plugged in. I noticed the charging light on the laptop would still light on so I assumed the battery didn't work anymore. I took off the battery and pressed the power button while plugged in and it turned on again. That worked for about a month or two but then it shut off again and this time I couldn't turn it back on and the charging light didn't turn on either.  I'm assuming the battery is no good so I need a new one, but would I also need a charger? Or did I mess it up by using it without the battery or something?  I bought it in 2012 and used it for about 2 or 3 years before that happened and I just want to know if it's an easy (and cheap) fix so I can recover my old photos and possibly give it to my sister for school.

Ok here is the problem we been having. It seems that we have problems with our breakers going on and off constanlty but this time it really affected our pc. Our stupid landlord didn't pay the electric bill so our power was shut off durring the night. once it was back on we tried starting our computer back on an guess what nothing happened.

So i checked things out. first i checked the reset switch and we bought a new one of those, new power cord for the power supply, nope that wasn't it.

There are two color light bulbs by the reset switch the green one comes on when the computer is working. its not turning on and the yellow remains on tho so i figured its still getting power but maybe not from the power supply but from the battery since its a pretty big battery. But the fan isn't running, neither are the drives and other things so i think it is in the power supply. Do you think it might be the mobo tho? This computer is only two years old and it has a celleron proccessor and so i was also wondering could it be the processor too?

So here is the questions, what do i replace first? The power supply , proccessor, ram, mobo or just buy a new comp?

Just to let you know yes its plugged in and its turned on and the monitor is turned on also.

First thing you should buy is a battery backup. Computers are very senstive to electrical problems, using a battery backup and a good quality powersupply will save you possibly thousands of dollars.

Most of these issues I've run into have a sort of chain reaction effect on the destruction of the PC. In all likelyhood, your powersupply is fried. If it was a good quality powersupply then that should be the extent of the damage, however if it didn't fail correctly then your motherboard could also be damaged. Depending on the quality of your motherboard, any various components of you PC could also then be damaged.

So giving that I understand your situation correctly, I'd first buy a battery backup (I prefer APC but Belkins are decent), then I'd buy a Powersupply (not a cheapo 350w Powmax, look for a good name like Enermax, Antec, Fortron, OCZ, or Seasonic) then see if your PC will start up. If its a no go then you need to replace the motherboard (at which point a system upgrade becomes an entertaining idea).

If at all possible try testing the components of your PC in another working computer so that you can devise what's good and what isn't.

But regardless, get a Battery backup.
