Lenovo z5070 i5 power surge

Q: Lenovo z5070 i5 power surge

Hello, Sometimes i have that power surge on usb port message and that port is the one that my mouse is plugged in. Whenever i get this message(usually once in 2 days), I cant use that port and i need to click to that message and when i click it shows me a page which can restart that port. The problem is when ? get the power surge on usb port device needs more power than port can supply message, I cant always click to that message and to restart that port, I need to restart my computer. I dont really want to restart my pc every time. It takes much more time than resetting that port. So do you have any suggestions that will help me to prevent that power surge, or even if it is not possible can you tell me how to go to that page which resets the port? I use razer mamba.Thanks.

Preferred Solution: Lenovo z5070 i5 power surge

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


My laptop shows a 'USB Power surge' error notification now and then, even though no USB device has been connected to the system. Please tell me how to fix this.

I have bought a samsung evo 250gb ssd to install my os partition to it from my HDD. I have created a recovery usb drive from my present HDD(controlpanel->recovery->create usb recovery). Then removed the HDD from the slot & replaced it with SSD & boot the system. While booting up i have selected boot from my USB drive which have the recovery, & continue the steps & finally submit the reset button.System shows "Resetting the PC" & after 10 seconds it shows a screen saying 'There was a problem resetting the PC, no changes were made'. I have tried several times but the same message came. Can any one please help whether the steps followed by me are correct , else please help me. Because i'm facing very much slowness with my present HDD(WD 5400 rpm), that's what i'm planned to move the os partition to SSD & keep the HDD in place of optical drive bay using a caddy. I don't want to loose my Genuine Windows 10 with my present system. So please help me with a resolution.

I'm having a bizarre issue where simply unplugging the official Lenovo power supply from the orange USB power port causes the laptop to immediately issue the subject warning, along with the detail "A USB device has malfunctioned and exceeded the power limits of its hub port".   This warning pops up every 5 seconds, unless clicked on, where reset/close options do nothing.  Crazy thing is, NOTHING is plugged into any USB port!   Reattaching the power supply does not clear the error.  Only rebooting with the power supply cable connected clears the error.   Remove the power cable, and the error instantly comes back.   All of the USB ports actually work fine, including the USB C port, whether or not this message is active. Maybe it is a hardware issue, but ALL the USB ports actually work fine.  I can't figure how unpluging the power source can trigger a USB power surge when nothing is actually connected and the battery is fully charged.  I've removed/reinstalled the USB Root hub, eXtensible Host Controller, Generic USB Hub, etc., drivers multiple times to no avail.   No errors with any devices are apparent in the device manager. I've seen a lot of issues reported about USB power surges but none like mine.   Anyone have any ideas about this?  System: Lenovo Yoga 900/16GB/Windows 10

Bought a XPS-8900.  When I switch the power strip on, the 8900 powers on momentarily then powers off (call it an "a/c power on surge").  From there it remains powered off until I press the power on button on the top of the 8900 and then it powers on normally and boots into Windows 10.
This a/c power on surge has never happened to any previous desktop PC that I've owned.
I always do a shutdown at night and then turn off the power strip to remove a/c power to the 8900, monitor, and external hard drive docking stations.  But the a/c power on surge that happens on the 8900 when I switch the power strip on is a major concern.  It seems that the a/c power on surge would be harmful to all of the electronics in the 8900.
Is this a/c power on surge normal for an XPS-8900 or other Dell desktop PCs?

A:Desktop power on surge when power strip switched on

That's entirely  normal!
BIOS has an AC Recovery option which tells the PC what to do when it recovers from a "power failure". Since you turn off the power strip at night, that's the same as a power failure.
So when you turn the strip on in the morning, the PC powers on briefly to see what it's supposed to do when recovering from a power failure. If BIOS is set to "do nothing", the PC powers off again, and you have to press the power button to boot.
If you're lazy like me, you can set that BIOS AC Recovery option to "reboot". So as soon as I turn the power strip on the PC starts booting and I don't have to press the power button.  Just make sure your strip can handle the load of the PC booting plus monitor and HDD all powering on at the same time.

Gateway 507GR Wont Power-On after a power surge. Had slight hissing noise in the Bestec power supply, replaced it, and it still will not always power-on. If I switch the a/c power on/off really fast while holding the power button, it will fully power-on after a few minutes of toying with it (tricky). Tested this new power supply in another machine, works perfectly, and so it's the board that's not powering-on. Removed the board and looked closely at the caps for swelling leakage, but what should I be looking for on the board after pwr surge? Any techs here familiar with this board/situation, very common that the failing bestec pwr supply takes out the board, the Intel E210882 MOBO. Thanks in advance.

I know how to enable/disable UBS ports, but I want to know if I Can set specific power limits for my USB 2.0 ports? using Windows 7 pro.

How can I test my motherboard to see if maybe that might be the problem?

Everything was working fine. Then, I started using a new USB device called Track IR5.

I don't know if it's a coincidence or the culprit, but I now get a "power surge" warning for all my USB 2.0 ports when the device is unplugged. USB 3.0 is not connected/active.

My headphones disconnect most of the time. My keyboard started disconnecting more frequently and my mouse is usually the last to disconnect.

If I plug Track IR in....
as well as my other peripherals (keyboard, mouse, 2 headphones, steering wheel), everything works fine.

If I unplug Track IR....
I'll start getting power surge warnings and my headphones, keyboard, lastly my mouse will disconnect (in that order) randomly.

It's also caused a cyclic "left click" issue with my mouse - I believe.
Over a span of 4-6 seconds, the left click button will go from standard to ultra sensitive to standard click speed again.
I can double click on a file and open it, and afew seconds later, it seems it only takes 1 click to unintentionally open that folder and then whatever file or folder my mouse cursor happened to be on, inside that folder. I slowed down and sped up the mouse click function in windows devices, but the issue still persists.

I have checked the wiring. Nothing exposed or touch... Read more

A:How to control all USB case power (power surge warnings) USB 2.0

Hi 7of9, welcome to the Forum.

Have a look at this MS website & see if any suggestions there work for you.


What happens if you leave the IR5 connected & shut down the computer, disconnect the IR5, restart the computer. Does your mouse etc. then work properly. If so it might be worth looking at getting a separately powered USB hub & using that for the IR5.

I have a Seagate 2TB external USB drive (Model: srd0sd1). Like an idiot I had it plugged into the wall without a surge protector. Yesterday we had some wicked thunderstorms which included 2 brief power losses. I unplugged the drive last night and hadn't tried to use the drive until today and it won't power on. Is it possible that the power source (AC adaptor) could be fried rather than the entire drive?!?

Hello,    I have a lenovo y50 laptop that seems to be having an issue.  My laptop has been on most of the day and was at lower power since I did not have time to charge it at all today.  When I got home and I plugged the adapter into the wall then plugged it into my computer, I heard the noise of the laptop screen instantly going black.  When I looked back at my laptop I saw that the screen what black, the laptop was off, and none of the lights at the bottom left of the laptop were on even though the adapter was plugged in.  I also then began to hear a chirping noise that was coming from the power adapter which stopped when I unplugged it from my laptop.  I then tried hitting the power button multiple times but the laptop would have no response at all.  My suspicion is that the adapter went bad and sent a surge to my laptop.  Does this mean that my batteries dead or has the whole thing been killed?  Also, if there is any suggestions that you have that I can do to find the problem/troubleshoot I would greatly appriceate it.  Thanks for any responses.

A:Lenovo y50 Adapter Surge

Hi Nozshund , 
Welcome to the Community Forums. 
Would you have the Machine number from the sticker or to get it from here (just keep the serial number confidential).  
You may also proceed downloading the hardware manual from the support site specific to the y50 model. 
Power checkout page on the manual would help you direct on testing the ac adapter to further isolate the issue. 
Battery charging indicator should also light up as ac adapter would be able to charge the battery on a normal power board and systemboard controller. 
Update us how it goes.

Sorry if this has already been posted and answered but I couldn't find anything else. I'm having a problem with my USB ports on my PC. It was custom built by my dad and has an Intel D845GEBV2 motherboard. The problem is that I keep on getting USB power surge notices popping up when ever I plug in any USB or device and even when they are unplugged. I've tried plugging them in, in different ports but it still has the error. My dad used this PC before and because of the problem, his USB flash drive burnt out. Is this to do with the software or hardware? I'm running Windows XP (non SP2). Also, I'm thinking if it would be a problem with the connections on the motherboard because there are only 3 cables (USB1, USB2 and Shield) and i'm not sure if they are plugged in correctly. Any advice?

I was away when a storm came threw and nobody shut down my puter. Now when I try to start puter first the mouse dont work any more. I had a Logitech MX 510. IT lights up but wont work. Installed a Radio shack mouse worked for a little it. Then it shuts down too. I try to start computer and tap on F8 key or DEL key sometimes it works an sometimes not if it works I am good for a little bit. 15min to 30 min then lock up. If i get into safe mode its ok until about the same 15min to 30 min. If F8 and DEL keys dont work It starts the process and then gets to floppy disk and fails. It say Floppy Disk Fail (40). I have checked and the fans are working and thats not a problem Hard drives work and 1.5 GB ram and thats ok too. So stumped and wondering if I can fix it or not. BY the way I dont smell anything hot or smoking in computer. My robotics router is fried as smell smoke in it so it toasted. Any help would be greatly appreciated.
Thank you in advance

A:Power Surge Help please.

If your robotics router gotten hit by a power surge and got fried, more than likely so did your computer, unless you had it on a good UPS (Uninterrupted Power Supply) system, one of those battery backup devices. Having just a plain old surge protector is better than nothing but doesn't help much except if there's a suddent spike and even then it might still get through...

As far as your system tho, it does sound like it got hit, If you can get a diagnostic cd for your system or download a few seperate programs like these to test each component seperately..

speedfan - measures power voltages, fan speed and S.M.A.R.T hard drive info..

DocMemory tester - tests your RAM..needs to be installed on a "bootable" floppy or CD, then ran from it..

Everest Home Edition - complete system benchmark and diagnostic program..

Also to test your hard drive, I would recommend looking in the computer to find who manufactured you hard drive, like Western Digital or Seagate etc, then go to thier homepage and downloading thier diagnostic software to test the hard drive. You might get lucky and just need to replace the power supply.

I am using a Dell Dimension 2400 Desktop with Windows XP. I have 2 USB ports on the front of computer. I plugged my digital camera in to download some photos. I recieved an error message...I cannot recal the exact wording but it's like this:

Window has detected a power surge through a USB port, the port will become inoperable. If you would like to restore the port, disconnect any devices and click here to restore.

I disconnected the camera from the USB cable and clicked "restore" . Nothing seemed to happen, the computer was frozen at that moment, non-responsive to mouse movements. I shut the computer down and re-started it. The computer seemed to re-start, one light on the case ( on the right side) was lit, all three lights on the keyboard lit and remained on, however I've got a blank screen, completely dark.

I turned off the computer and chcecked all of the connections, ( all was well) and attempted to re-start. The result was the same as above, no image whatsoever on screen..I see no indication that windows was engaging at all.

I'm utterly puzzled...any ideas?

Hey guys, what's up?

My brother has been getting frequent error messages saying the USB Hub has exceeded its limit, dealing with a power surge. This message only came up when he plugged in his gaming controller, and recently, I began getting the same messages. My computer specs are;

Dell Inspiron 6400, Windows XP Pro SP2, 2.16 GHz, 2.00 GB RAM

My USB drives are currently occupied by the following;
1. A Logitech V450 Laser Cordless Mouse
2. A Saitek P2500 Rumble Force Gamepad

Two weeks ago, my brother began experiencing these problems. I, on the other hand, didn't, and used the wireless mouse with the gamepad at the same time, 5 days a week for more or less 2 weeks in duration. Tonight, I received this message for the first time.

After going problem solving, I downloaded a patch that disables the error bubble; however, neither the mouse nor the gamepad work when both are plugged in now.

I fooled around with it a bit, and the mouse works fine without the gamepad plugged in. The gamepad on the other hand doesn't, and disables both USB ports when it is plugged in. I tried plugging in the mouse with my printer/photocopier, and it works as it did last week.

I have read that this can be either a small problem, or one as large as needing to replace the motherboard. Ironically, my Dell warranty just expired (this is roughly the 4th time that something has happened to a desktop/notebook while with Dell where something occurred just after the warranty expired [rum...

I even used the same power cord for a different tower in my room and that turns on, but my computer won't. Anyone have any suggestions, I'm kind of stumped and tapped out on ideas?

A:Possible power surge, now tower won't come on

Top suspect would be the power supply, it's the first thing in the line of any surges.

One time I unplugged my computer from the wall by pulling the plug(I know better than to do this)

Anyway, when I unplugged it, I could see a small spark from the outlet in the wall. Somehow it appears that this broke something in my computer, because when I try and power it up, it won't power up. This computer is a pentium II and I have not used it in a few years. I do have some very important files that I need to get off of their though. Does anyone have any idea what might possibly be wrong? Is their some type of power device in the computer that might be broken that I could possibly replace on my own?
Years ago I use to replace hard drives and graphics cards, ram etc. So I am a bit of an IT guy. Anyway, I would appreciate some advice on this.

Hi when I plug in my Razr V3 cell phone to my pc, I get the "Power Surge on Hub port" message and the USB ports shut down till I unplug the phone. However, I was able to bypass this error and get my USB phone to work when a computer guru let me borrow this special USB cable that had one end that connected to the phone, but the other end had 2 USB plugs that simultaneously connected to 2 of my USB ports instead of one. I was told that this way, the power supply demands of my phone were split and shared betwen the 2 port. Now I'm trying to buy one of these special USB cables but I don't know what it's called. Would really appreciate your help.

Hi everyone!

I got a situation with my friend's PC that I've taken in to take a look at.

He says that one day there was a huge power surge and when he attempted to power on his PC, it basically just emitted one long, two short beeps.

I took the PC from him and since there was no video output what-so-ever, I decided to swap the video. I also looked at a handy little beep codes guide from these forums that also confirmed this.

Upon putting in an older (known working) video card, the PC booted. It went into Windows just fine. While in Windows, out of nowhere the computer would hard freeze. Nothing works when it would do it. No ctrl alt del. nothing. The computer was virused out beyond all belief so I decided to just do a clean install of WinXP.

The install goes fine until after the GUI portion of the setup, it hits a black screen and sits there completely frozen with an hour glass. It may possibly by the part where it auto-adjusts the display.

Could this possibly be because the video card I thought worked fine is bad? Or could it be possibly the surge annihilated more than the video? MB?
Edit: update to above information

Since it got past the GUI portion of the setup. I decided to just boot from C: and hope everything would still work. I unplugged everything and brought it down to bare bones. It booted into Windows but hard locked after about 15 seconds of a clean install.

I decided to pull a stick of RAM out and use memtest86... Read more
