ThinkPad P52 is not getting powered through the power supply

Q: ThinkPad P52 is not getting powered through the power supply

Hello Community I've got a brand new P52 with a Thunderbolt 3 workstation dock. Unfortunately the system is not getting enough power to keep it running. If I attach the power to the system the battery is getting charged, but as soon as I boot the system up, it reports that it is not getting enough power to run the system. It doesn't matter if I attach the system to the workstation dock or to any of the power supplies directly (170W or 230W). As soon as the system is booted, not enough power is being supplied and the system runs on battery. I've already installed the latest drivers to both the system and the workstation dock. Any idea how to fix that? I've tried to open a ticket at this brilliant eService Ticketing, but this won't let me create one. The Link to the video regarding possible causes seems to be broken as well. https://support.lenovo.com/vidoes/VID100760 I'm realy pi... off spending half a day failing to fix it and unable to open a support case. RegardsChristian

Hi all!
I've got a strange problem that I've never encountered before. I had a power supply go bad and I replaced it with one I know to be good from another pc. In fact, I bought a new one also.
This happens with both power supplys.
The pc is a Emachine T2882 w/Celeron 2.8G running XP Home.
Anyhow, when I power the pc down I noticed that the heat sink on the processor was really hot and I also notice that the little light in the front that tells you the HD is working was on AND I noticed that the fan in the power supply was running. All this when I powered the pc down via the START>Turn off computer>Turn off
This could be what burned out the power supply in the first place.
Has anyone ever heard of this? Can someone help me out with this strange scenario?
Thanks so much and may God bless,
Peter

Hi folks! I've noticed the problem 2 weeks ago but was too busy at work to write this down.. Laptop still switching on and off to airplane mode with the details of some ac power supply problems.. I've just ran hardware test which freezed at 27%.. but then has shown no hardware problems.. When I twist the cable up or down, etc.. starts recharging but not sure where is the problem.. is it the cable and ac power supply or the socket inside the laptop ? how can I get this sorted.. warranty expires in 54 days.

Hi, I am pretty new to this forum so I'm not sure whether I'm correct here, I just hope it is.My device is a Thinkpad A485 with the Ryzen Pro 2500U.I am using Linux (Debian to be precise) on this machine btw, to defuse some confusion that could come up, using the mainline kernel 5.1.0-rc2+ (master from torvalds master branch), but these issues are also occuring on the kernel supplied by Debian which is 4.19.0-4-amd64. The issue in detail I am experiencing is:When I cold boot the laptop without a USB device attached, the USB ports won't give any power until the power supply is plugged into one of the USB-C Ports. When I connect a USB device to one of the USB ports, it doesn't do anything, until I plug in the power supply, but when removing the power supply again, the device remains powered. This is not happening, when the USB device is plugged in while the device is turned off or while it is in the bootup process. Also ethernet seems to be affected by this as the same issue is occuring with the ethernet port on the right side.Is this a know issue? I did not test this on Windows 10 though.I doubt that this is a hardware issue as the devices keep getting powered when the power supply is removed until I plug them out.I wonder whether other people also have this problem.

If you plug or unplug power supply, the screen goes black for few seconds. I noticed it working on a train connected to the AC power: every power failure the display turned off for few seconds. Very very annoying issue! I hope that an upcoming driver/firmware update could fix this. Does anybody ever experienced this issue? I'm quite sure this is not an hardware failure.

I have a W540, which currently uses a 170W power supply (20V 8.5A) I also just recieved a docking station for a P50 which has a 230W power supply showing 20V 11.5A. The connectors look the same, but I'm hesitant to try the 230W power supply in the W540. Should this be ok to use the 230W power supply with the W540?

A:Power Supply Question - Can I use the 230W power supply with a W540?

230 watts is the maximum power supply, it only supplies the power needed by the computer. I sold my W540, so i can't test this for you. But i do the use the ThinkPad X1 Carbon with the 230 watts power adapter without any problem.

I have 2 failed Z800 power supplies (1150 watt version). After some internet research I am led to believe this is a common problem and related to the PS capacitors. Since I do not know how to do this capacitor replacement (yet). I thought I would buy a new PS. However, I do not want to buy a Z800 PS since it seems to me to be a defective design. Can anyone chime in and tell me if the new z840 1125 watt PS will work with my older z800? I have called HP support and spoken with the correct support people on this and they were not able to confirm if the Z840 PS will work (fit) on the z800. The closest confirmantion I recieved was that if it fits then it should work. Instructions to fix the capacitors:http://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/Z800-power-on-issue... Same issue I am facing:https://www.youtube.com/watch?v=f563JGeoxaw On a side note, can anyone recommend a good service tech to make such capacitor repares in Southern California or insrtuctions on how to make this repair (with pictures). Thanks

Hello,    I recently upgraded Thinkpad P1 BIOS version from 1.15 to 1.17 via ThinkVantage but later on I found the new thermal setting is more strict than the previous version (thermal throttling threshold is lowered from 90c to 80c). Therefore, I downgraded BIOS version from 1.17 to 1.10 (N2EUJ05W) using the old BIOS package downloaded from https://support.lenovo.com/ca/en/downloads/ds504956. Unfortunately, after the downgrade, the machine cannot be powered up anymore. Is there any way to fix this issue other than claiming the warranty? Thank you!

Hello, I have received 2 Lenovo Thinkpad W540 workstations from my work as they retired them and gave them to me for personal use. They were securely wiped when I received them so I installed windows using my personal usb stick and a fresh installer from Microsoft. Both work and boot up perfectly fine at this point. The issue is that once they are turned on the batteries will not charge, windows doesn't even detect there is an ac adapter connected. Now I know that the immediate assumption here is going to be that the ac adapter is faulty but I would argue it isn't. I took the batteries out of both of them and used the ac adapter to run them. Both boot up correctly and I ran Prime95 on them for 30 minutes without the battery installed and they were fine. I monitored the core clocks and neither of them were seemingly power starved and maintained a consistent 2.9 GHz clock. So with this my feeling is that the adapter can provide enough power. It is a 230W adapter and the rating for this laptop is only 170w according to the Lenovo support portal. I have tried to reset the battery, change bios settings and have spent atleast 4 or 5 hours googling this issue and nothing I can find helps. Anyone have any other ideas? Thanks!

Ok, I just built a new computer that I ran for about 2 hours give or take then it powered down completely during my OS installation. Now it won't even power up at all, I switch on the power supply and the green led on the motherboard lights up, pressing the power button however does nothing.
My worst fear at the moment is that I have fried the CPU by applying too much thermal conducting past between it and the heat sink. (I didn't apply the thermal conduct myself, I had my room mate helping me, I wasn't aware of how much was supposed to be applied.)
Now the question I have is, would that be the reason why nothing happens when I hit the power button even if the green light is on?
Another thing to note is that the cpu heatsink fan I bought already had a small amount of Thermal paste on it which we failed to notice right off.

Computer specs:
Asus M2R32-MVP Motherboard
Asus EAH3850 ATI Radeon Graphics Card
4 GB Kingston 667 Mhz RAM
dual 80 GB Seagate SATA HDDs

Hiya Guys.

Something strange has been happening to the USB section of my computer and I wondered if anyone could shed some light on it for me.

I bought a USB powered 1TB external hard drive (ie: the one USB lead gives it power and data transfer). I connected it directly to a computer (XP Pro - SP3) and it found it, installed it and I was up and running but when I connected it to a 1 metre USB extension lead in the same port on the computer, it failed to install and the drive started clicking which we all know is a bad sign.

After re-connecting it directly without the extension lead, it went straight into it and worked like a dream until out of interest, I connected it via the extension lead and again, it failed. I don`t think the drive is at fault as it works every time when it`s a direct connection and fails every time it`s through the extension.

In case you`re wondering, all ports are USB 2.0 rather than 1.1 and as I have access to a few other machines, I`ve tried the `test` on those with various leads and directly, ending up with the same results.

My question is ... Can a USB extension lead take just enough power that it tips the balance and not give the drive enough to initialize itself?

Regards Jenny

A:PC powered off and wont power on?

Try disconnecting everything non essential 1 at a time. If you disconnect 1 thing and the computer comes on, you'll know what is caysing problems. Just because a light lights up or a fan spins only means the PSU is putting out some power. It does not mean that it is putting out enough power to run a computer. If you have access to another known good power supply, try connecting that and see if it comes on. If needed, see if you have afriend that will loan you one to test with. The PSU you have is one of the better PSU's you can buy. They rarely give you problems. Try those things and let us know the outcome.

Problem:

Computer powered off while in the middle of me using it. Tried to power back on, but nothing happens when the power button is pressed. Tried unplugging the power supply and back in, still would not power on.

Troubleshooting:

Hooked up my PSU to a PSU tester I have = Good

Replaced Motherboard = no change (indicator light is on, on the motherboard)

Checked power switch = Good

I also tried taking out my video card, left one stick of ram in, and still nothing.

The only thing i haven't checked is my CPU, I have just ordered the E8400 in hopes this will fix my problem, but I was hoping to get a little feed back on my situation as I have come up empty when searching online for a simlar problem.

I appreciate any feedback I can get!

Does such a thing exist?

I sometimes find I need my external drive for like 5 minutes on the road without a socket in sight so it'd be great if I could just have it suck power from my computers USB port.

Or even solar power.

Obviously I wouldn't power something for a long time with it.

Or it'd be great if only one plug is available like at a coffee shop

Anything like this on deal extreme?

A:USB to electrical power plug? / or solar/AA powered

I think the best solution for you would be a portable hard disk that don't need external power supply. I've been extremely happy with Western Digital products, using this 640 GB as my "on the road" drive. It fits to my jacket pocket.

My Yoga S1 has contradictory, intermittent power issues that I'm trying to chase down.

I did get an error code which I can't remember 5100 or 5500 poss?, that seemed to indicate the power board or ribbons to that needed replacement or re-attachment. So fiddled with it and it did fire up in windows all ok. Then ran out of power and died again. power button wouldn't light up. plugging in power unit did light up led as getting charge. Left it overnight and then it miraculously charged up. pushed power button light up twice then nothing. took out power board/detached ribbon, then it fired up to windows, fixed some hd errors and has been restarting without problems. Except now there is no plug showing on battery icon when plugged in. So not recharging but I'm sure the battery is good. And logically, the power brick and plug must be feeding electricity into laptop to get it to recharge enough to start up.

Hi, so I have had a powering issue with my previous power supply which was the Corsair CX600W so i purchased a newer power supply - the EVGA SuperNova G2 550W. I unhooked my old psu, hooked up my new one and the PC turned on and I turned it back off from the power button on the case. I also hava a boot drive problem so I unplugged the sata cables from my SSD and wanted to try to turn on the PC with only my HDD. I did this with the PSU switched off and the power cord unplugged. When I tried turning the PC on again the PSU made a clicking noise and nothing turns on. The motherboard Led's are lit up so it is definitely getting power but when I go to turn the computer on it just makes a quick clicking noise and nothing turns on. Any help is appreciated, thanks!
 

A:Power Supply makes clicking noise when I press power button

You may just need to drain the power off from the power supply and try again. Unplug the power to the power supply, press and hold the power button for 30 seconds, then plug it back in and try to turn on the computer again. If that doesn't put the old power supply back in and see if the PC works, or was the old one dead? If the PC works with the old one and not the new one then you may have gotten a faulty power supply.

I'm interested in the Toshiba G25 laptop but have heard that you can't use it on airplane seat power. It comes with a 120W AC power supply (15Vx8A), but I've been told that most airlines limit seat power to 75-90W max. Lind sells a 12V car adaptor for the G25, but specifically won't include an airline plug for this reason (which I can get independently, of course). I've read some interesting electrical discussions on this board. Can ya'll comment on the following or provide any general advice about power consumption?

1) Given that the voltage of the laptop and airline seat power pretty much match up (12-15V), if the amp draw on the laptop exceeds what the airline power supply can deliver, what will happen? Will it damage the laptop to feed it insufficient current? Will it shut down the laptop altogether? Merely dim the screen?

2) If I remove the laptop battery, which requires power to charge it, how much will that reduce the power need of the laptop? I'm not sure how to work the math, but the spec sheet states the battery supplies 4400mAh at 8A output. Does it require the same to charge it?

3) Most importantly, on my 15 hour transpacific flights, will the DVD player work with that ultrabrite screen at the low airline power supply? A nice feature of the laptop is that you can watch DVDs without powering up the Windows operating system (it has a small linux OS for the DVD player). Granted, the DVD drive and screen are prob...

The laptop is in pristine condition but shows no signs of life.

If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.

Remove the laptops battery and try the AC power only. If the green light does the same, it still could only be a bad AC adapter, or at worst, a shorted laptop motherboard

It wont work at all with; (Nothing happens its just dead)
Arctic 600 watt Jeantech PSU (brand new and working)
Corsair 620 watt HX PSU (working)


It only seems to work with my Jeantech 450 Watt PSU and i cant for the life of me figure out why. Ive tried everything to get the board to work with the new PSU's. I had thought that the PSUs i got were dodgy but after testing out one in an older PC it worked fine.

Ive removed all parts and tried powering up and i cant get it to boot up. But the PC seems to work fine with the oldish 450 watt PSU which i find just unbelievable.

Can anyone help with this nightmare? Now on the Gigabyte site the CPU i have isnt listed as supported by this motherboard which is kinda worrying could this be the reason? If so how the old PSU boots up.

I just want to have the fracking thing working with the right PSU.
 

A:Power Supply Wont Power up - Gigabyte ga-ma790fx & AMD Phenom 9850

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

Hello: Just received a beautiful W530 Laptop - love the T and W versions of this machines. However, with such a large power requirement, want to make sure that I will be able to run and charge the W530 on United Airlines, American Airlines, etc., using the supplied 170 W Power supply...  Please confirm your experience that this will work. Otherwise, using this laptop on long haul flights will not work.

Hello everyone, ? It's been a year since I bought a ThinkPad X280. Yesterday night, I plugged my phone to charge and close the lid before going to bed, while forgetting my phone still left plugged. When I woke up, I saw that my phone was at 0%. I turned up my computer and tried to plug it to charge but it refuses to do so. And yet, the computer is still able to detect it and transfer files. The only problem is that: it does NOT charge! I tested on this USB port another phone, and on a different operating system : same problem.I tested the second USB port on my laptop, everything work just fine.I believe that this is a hardware problem. Has anyone encountered this probkem before ? How should I solve it ? ?? NB. As a personnal note, I may say that I am highly disappointed by ThinkPad products. My first ThinkPad was a X1 (1st gen.) and every year, something just suddenly broke: keyboard press key, fan, motherboard, SD card reader. I had hoped that this was due to this product line and decided to buy a brand new X280 to give a new start of my opinion on this product. I must say that I am highly disappointed as my laptop is just 1 year old and that I barely use it anywhere else than home. The product quality is bad. I am not sure I will continue buying ThinkPad in the future...

I have just bought a Dell 19.5 V 90 W power supply adapter for a Dell from ebay. The PSU turned up this morning without a power cord. That's annoying enough but when I looked the connector needed is a type I have never seen before. The centre pin is slightly longer and wider than the other two so I assume that is the Earth pin. The centre pin is also offset between the other two. Again I suppose for connecting only 1 way. The two outer pins have a distance of just under 2 cms between them. Please can anyone tell me what type of connector this is. If I can get some info on it then I may be able to get one.

Thank you Terence

I've recently inherited a lovely Y70-70 touch from my father, and have restored it to factory settings recently. However I'm having issues at the moment where it shuts down instantly at random times when not plugged in. Checking the system logs in the event viewer I see the following Critical message: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Generally online help seems to suggest this is a power supply issue. Have I got a duff battery in here? Are there further diagnostics I can run? Unfortunately I'm out of warranty so keen to solve this myself!

Hello guys.  Can anyone help me understand the power supply on the HP Envy Phoenix 860-019?  The PCIE connector 6 pin connected to the GTX 960 has black and white wires.  Shouldn't there be yellow and black wires?  Yellow is usually 12 volt and black wires ground.  Is the 6 pin connected to my GTX 960  supplying a standard 75 watts of power or something else?  I want to install a GTX 1070 but the 6 pin wire colors are not the industry standard color scheme.  Also there is a 2 pin power connector with a white and black wire.  Usually a 6 pin and a 2 pin can be used together to connect into a 8 pin socket on a GTX 1070.  Will my connectors supply the needed power and connect properly because the color scheme on the wires make no sense. Thank you

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

A:No Power, Blinking green light on power supply and motherboard

Sounds like a Power Supply problem.

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.
 

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

Sorry I don't know the proper terms, but basically the pin inside the jack where the power cord gets plugged into on my laptop was bent so that it's really hard for me to plug in my power cord and have it stay in place. My warranty with best buy has expired, so I need to figure out how to solve this problem on my own. I can't just leave it like this because the cord comes out really easily and I can't continue to work with such a tenuous setup. Anyway, is this just a matter of replacing the entire unit inside my laptop? I know you probably need more information, but I'm not sure what to provide, so please ask any questions. The laptop is a Toshia M-45, about 3-4 years old. Thanks in advance
 

A:Bent power supply pin - Hard to plug in power cord

umm.. bend it back so it's closer to normal? That's all I can say about it. usually works for me.

It's been a while since I built a system from scratch and have a... errr... simple question

gfx: Sapphire HD3850 512MB Ultimate (passive)
http://www.sapphiretech.com/us/products/products_overview.php?gpid=225&grp=3

MB: MSI P35 Neo2 FIR
http://global.msi.com.tw/index.php?func=proddesc&prod_no=1261&maincat_no=1

PSU: Seasonic M12II 500W
http://www.seasonic.com/product/pc_retail.jsp

The motherboard has a power connector for the graphic card next to the slot.

Is there any reason I should connect the power for the card to the power connector on the board instead of directly to the power supply?
 

A:Graphic card power to power supply or connector on motherboard?

First time I have ever seen that feature. I like it. I'm thinking that is a neat/easy way to partially eliminate cable clutter from the PSU. Give it a shot, you can always revert to PSU cable if you wish.
