Q: Yoga 710 not turning on without power supply plugged in

Hello, Just bought a new shiny Yoga 710 14. Have a very weird issue:- Laptop switches on with power adapter connected, without it pressing On button does not trigger anything. Tried pushing it for 30sec, 1 min - no luck. When I plug adapter works perfectly, when I remove adapter while ON - everything works perfectly. Battery charges and discharges normally

From new the Yoga 910 has always seemed to have problems. I've posted in detail about speed problems before but with regard to fan noise : https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Yoga-910-crazy-loud-fan-even-when-CPU-at-l.... I'd like to raise this issue again though since I've discovered that the Yoga is distinctly faster 10-20% when on battery!!! I presume this is due to the way the BIOS is configured to ramp the Ghz up/down to balance fan noise with CPU temperature (I have the BIOS set to quiet mode since anything else is both noisier and slower - see my link above.) Apologies for the size of the screenshots but they accurately show the nature of the problem - when plugged in the raytrace rendering (using Blender) is 22 seconds slower and Task Manager highlights how, on average, the % utilisation and Ghz are lower than when on battery. And after several attempts this is consistent. So my question to Lenovo is why is my laptop slower when plugged in and please Lenovo can you adjust the BIOS so when plugged in the laptop operates at least at the same speed as on battery (without breaking the fan quiet mode which is already too loud). Oh... and I have checked my power options in Windows 10 and there's nothing that would indicate that being plugged in would limit the performance. Performance on batteryPerformance plugged in

Hello there, recently I've been having a few problems with my PC. When I try to turn it on, the lights will start up, as will the fans, but nothing appears on my screen, my monitor showing a "no signal" message. However, if I keep turning the switch on and off at the back by my power supply, and pressing the power button it will -eventually- turn on.

When it's on it seems to be slower than how it was before I encountered this problem, about a few weeks ago, sometimes programs would randomly stop responding for example.

Is there any simple troubleshooting I can do, to find the issue?

Sorry if this is in the wrong area by the way, mods.

Hello. I have a question that I hope some one can answer. I have a APC Uninterruptible Power Supply with my PC, monitor and Logitech cordless Duo plugged in to it. Whenever I have to clean all the dust bunnies under my desk I plug my vacuum into the same wall outlet as the UPS. When I start up the vacuum I usually get a Electronic Noise Warning saying the my UPS turn on for approximately 4 seconds.

Today, during vacuuming my PC didn't give me the message, but turned itself off. When I restarted I went into my APC Powerchute and there was no log of any power problems or the battery backup turning on.

Can someone tell me if this is a normal thing a UPS does? Thanks for any info.

its very simple answer.



What your computer expects to get from the power grid (in the Unites States) is 120-volt AC power oscillating at 60 Hertz (see How Power Distribution Grids Work for more information). A computer can tolerate slight differences from this specification, but a significant deviation will cause the computer's power supply to fail. A UPS generally protects a computer against four different power problems:

Voltage surges and spikes - Times when the voltage on the line is greater than it should be
Voltage sags - Times when the voltage on the line is less than it should be
Total power failure - Times when a line goes down or a fuse blows somewhere on the grid or in the b... Read more

Ok, I just bought a new HP PC with a 24 pin mobo connection,but the included power supply is rancid;a 300 watt max Bestec model ATX-300-12z.

I have a much nicer 450 watt Antec I'm putting into it but only has the 20 pin instead of the 24 pin. the 4 pins missing are #'s 11,12,23, and 24 and are there to provide extra power to the board which i will need for a PC-Ex16 vid-card I'm putting in and extra hard drive.

Can I just use a spare Yellow 12v,red 5 v,Orange 3.3v, and black ground that are comming from my antec PS and stick them in the last 4 pin slots? im pretty sure it would work, but wanted a few more opinions on it first to weigh my options carefully.

also,my antec has the white -5v in slot 20 but the bestec ps that came with the new PC has slot 20 left empty. I'm guessing i should remove it from my antec ps?

Thanks for any help/opinions(i know the smart thing to do would be buying a shiny new power supply,but I'm all tapped out on cash)
 

A:Power Supply Turning my 20 pin into a 24 pin connection??

You can buy the proper adapter cable for the job: http://www.newegg.com/Product/Product.aspx?Item=N82E16812189061
Its not the best way to do it but since its replacing a 300 watt unit I can't see it being any worse. Normally its a bad idea because it takes the amperage from the other rails and splits it up to provide the additional 12 volts needed by the system.

You can leave the -5 volt wire connected, it just won't be used.

Hello, ( Sorry if the title seemed inadequate as I have no idea how to phrase this) For the first time in 3 years, I just gotten my BSoD, and I do freak out. Prior before just getting the BSoD, everything froze, my mouse which changes color also froze, I then proceeded to see if my numlock would turn off, and it didn't, thats when I knew, sh!ts gotten serious! So after I got the BSoD, I wasn't calm enough to properly take my time and read everything, but I believe it said something like "Clock interrupted". I then proceeded to unplug my PC, I notice it's a little "wobbily" I assumed that the power supply or adapter inside my PC is maybe not tightened in properly? And of course theres the issue of malware/viruses, I have done a scan with COMODO and MAB and my system is completely clean. So, advice from the BSoD experts would be greatly appreciated.

Hi, I'm not sure why the computer is doing this, but whenever I plug in the computer, the power supply starts buzzing, and the LED light that shows if the computer is on automatically turns on once I plug in the power. And if I push the on/off button the computer doesn't respond to it at all. Not sure why this is happening, but please help.

A:Power Supply buzzing and computer not turning on

Sounds as if the Power Supply has gone out, or the MotherBoard has shorted and is gone. The easiest way to check would be to find a replacement Power Supply and install it.

Has the computer been plugged during an electrical storm without being plugged into a surge protector?

Hello, I the power supply light of my Media Center m1050y is blinking and the PC does not turn on at all. So I tried the troubleshooting sequence posted here in the HP Support site, and after unplugging all the cables and replugging them one by one, it turns out that the light blinks only when the PS is connected to the mother board (the connection is a white, wide plug with about 12 pins - pardon my ignorance on the actual name). I looked on the internet about trying to narrow the cause on the motherboard and I unplugged the front USB ports, the fan, and other "solutions" without any luck. Does this mean the motherboard is fried and either I need to replace the motherboard or look for another PC? Thanks!

I recently had the internet connected at my cottage. I am using a TP-Link router model TL-WR740N.

Hello and good day,
This is a truly strange scenario, I am sorry to hear that you are having this issue. You could try to dig into the power options for your laptop and see how it affects your wireless adapter when running on battery. Still, since this has never been an isue with your home setup, we have to point our fingers to the router itself, regardless of how well your other devices work with it - all the devices should work well with it.
Sorry that is all that I have for you.

One of the ribbon cables may not be securely connected. Them things are a pain to deal with.

If you hadn't previously worked on it, I was going to suggest the power supply may have gone bad. Since you worked on it and that is when the problem started, its been my experience the problem is nearly always workers error.

Hi bfc1 , 
 
 
Welcome to the Community Forums. 
 
Best that you also try to remove the battery , harddrive , memory and press down the power button for 15 seconds to power drain while unplugged .  then connect the charger and press the Novo button if power would not show any activity. 
 
What is the machine number from the sticker so I can get you the hardware manual for reference specific to your machine . You may also go to the support site for the manuals .
 
There are times that it is not always the motherboard and just DC in connector that is having the issue if not a power daugther board.  Check for any burnt marks or bulged capacitor if you have the tools or skill .
 
Update us how it goes.

A:Yoga 900 power supply

I'm a little confused. Are we talking about a power bank or a USB hub? A USB hub is the thing you use to connect thumb drives and other peripherals to a computer. They will charge phones, but that's about it. A few powered USB-C hubs are designed to passthru power to some computers via USB-C, but that doesen't work with every brand of computer. 
 
A power bank, on the other hand, is little more than a battery with USB connectors on it for charging phones and such. 
 
It'd help to know the model number of the Ravpower device you're talking about so I can look up the specs.
 
I've a feeling you're trying to charge a computer that needs a 20V, 3.2 amp charger with a device that only spits out 5V.

It is advised to stay with the same charger that goes with your machine and have known to work for you. It would be better specially if you are not receiveing any message prompt about any need for more power from the system.
 
Hope this helps answer your query.

So three weeks ago, I was working on my Yoga 3 14" and popped to get a drink, I came back and the screen was blank, I assumed it had gone to sleep, so hit a key to wake it up. Nothing! The laptop was plugged in, so I know it hadn't run out of charge.After sheer panic, I contacted Lenovo, who told me that my warranty was out by a month, and that I could send it to them to diagnose, and they would tell me how much to fix, then it was up to me if they did or not.One I wouldn't be happy about not having my laptop for a couple of weeks minimum, but also it had all my private information on.I turned to good old google, and stumbled across this forum, and somebody with the same problem.Their solution was to unscrew the back case of the laptop (as mentioned above, my warranty was already out), remove the battery cable, hold down the power button for 30 seconds and reconnect the battery cable.I did this, and low and behold it worked. Fantastic!Only for it to happen twice more that week, and approx twice a week since. Then yesterday my brother contacts me saying his laptop has died, just won't turn on.

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.

6.3 A of current, it won't function on less (just as you can't use a 3A fuse for a kettle!)
Unfortunately it must be the right current rating, I know, I've been caught that way too!
Maybe you can exchange it?

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.

Ever since i got this new motherboard and CPU ive been having a bit of a nightmare with it.

Gigabyte ga-ma790fx-ds5 -Latest Bios
AMD Phenom Black Edition 9850,
4 gigs PC 6400 ram (Corsair XMS2 CM2X1024-6400
ATI Radeon 4870

The problem is that the motherboard will NOT power up at all with the 2 of the latest power supplies (600 watt+) i have.

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.

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...

Hi,
I picked up this Alienware 5700 off ebay to hopefully refurbish for my son but I'm new at this and still learning and so this thing has me baffled. The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? 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.
 

A:No power, no lights but green light on power supply blinks rapidly

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

I have a Dell 8600 about two years old. When I plug in the AC adapter, it intermittently fades to the battery as though the plug was pulled out (its not) and of course the screen fades in an out when every time it swithces--it does it every 30 to 60 seconds or so. I switched to a different AC adapter (I have a Dell 600M with the same AC adapter)-same thing so I know it is something internally. Any ideas?

I have an enquiry relating to video cards. In order to do my job, I need to get a card with at least 512MB of VRAM, preferably 2GB. However, the ones I've found online use 300w What's the maximum watts that I can use with my Lenovo H520s? And what would happen if I used a 300w video card in it?

A:What graphics card will my H520s power supply support (PSU, power calculator)

Use a power supply calculator to get a accurate calculation of your power requirements.   Graphics card manufacturers have to figure a worst case scenario when giving power requirements.

Mod:  removed the Newegg calculator, which only gives a recommended psu size, rather than a power calculation.   The CoolerMaster gives both.

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.

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.

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
