Two computers died overnite...power surge?

Q: Two computers died overnite...power surge?

I have 3 computers; the one I'm on now which is plugged into a surge protector, one in an office that is just for checking email and such, and a system behind the TV running linux and MythTV for PVR functions. Besides the one I'm on now the other two are just plugged into the wall, due to the fact that I'm lazy and didn't buy more surge protectors. Please do not patronize me about not hooking them up to surge protectors...I really don't care right now.

After last night both computers that are not on surge protectors exhibit the same exact problem (which to me is very strange). The power button has no effect, they will start if you plug the cord into the power supply and its switched to ON. Obviously it won't start up if the power supply is switched off. So as soon as you plug in the cord they turn on, all the lights on the front panel (power, HD activity, etc) remain on but the monitor will not turn on and it won't make the "everything is cool" beep sound.

Both computers exhibit that EXACT same problem which allows me to rule out various things such as individual component failure (though I suppose it is possible yet highly improbable).

Are these symptoms of a computer damaged by a power surge or something else? Solutions?

*note: I know my way around computers (I built all three machines from parts) and have checked all the usual things (connections, etc.). Yes, I'm an ***** for not plugging them all into surge protectors if that is indeed the problem...I don't need to hear that again.

Also, I've stripped down one of the machines to just power supply, motherboard, CPU/HSF, with the power switch and speaker plugged in. The power switch still has no effect (just boots when plugged in) and NO BEEP CODES.

I'm starting to get scared taht these two machines are totally bricked...please, somebody help me.

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.)

Hi guys,

Hardware not being my specialty, I'm coming to you guys for help.

I just bought a new computer running XP pro - Pentium 4 - 3.0 - 800 MHz - 512 RAM - HD 80 g but am keeping my old one to tinker with.

The old one is Pentium 4 - 1.60 - 256 RAM - HD 40 g running W2K pro.

I'm setting them up now but need to know if I connect them both up to one (good quality) surge protector bar or is that asking too much? Getting another bar is not a problem if necessary it's just that I don't have one at the moment and like a kid in a candy store, I can't wait!


A:Solved: Can I run two computers on one power surge bar?

I'll assume your power up there in Canada is the same as the US 115v, a normal circuit breaker is 15amp or 20amp so one outlet with nothing else on that circuit is good for 115x15=1725watts or 115x20=2300watts, so yeah go ahead, but i would put it on its own surge strip when time allows.

Whenever I connect my 2.5'' Hard drive via an enclosure, it causes power surge on the usb ports on multiple computers, does this mean that the hard drive is screwed already ?

Thanks =)

A:Hard drive causes power surge on multiple computers..

How do you know it causes power surges?
If you are sure it causes power surges on several systems I would first check the cables. If they are okay I would backup all data if you can and replace the hard drive. A hard drive can go bad any time.

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

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.

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.

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?!?

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 don't know if it's related or just a coincidence, but after my computer (OS Windows XP) automatically downloaded Service Pack 2, I keep getting these reminders from the toolbar that I have a power surge on a unknown port; unplug the hardware; and reset. I can't figure out which unknown port they're talking about. I have a monitor, mouse, keyboard, printer, and speakers. The message isn't causing any other problems. I just click on the reset option without unplugging anything, it goes away and then comes back on only when the system has been "sleeping" and I hit "enter" to wake it up. Any suggestions?

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?

Yesterday, being conneted to the internet i had a power surge and my computer turned on and off rapidly, well when it booted back up i discovered i could no longer conenct to the internet, the computer no longer recognized that i had a LAN connecttion, i checked the router and it is fine, my other computers still are able to conect. Other than being unable to connect to the interenet the computer is unaffected, even trying a different ethernet cable didnt work. I think i have the problem narrowed down to 2 options, either the surge fried the NIC card, longshot that it didnt affect anything else, or theres a data corruption somewhere in the driver that runs the nic card? any opinions on the matter? or a solution?

A:LAN not being recognized after power surge

well I had a somilar proplem with my onboard sound. The electrical surge damaged the relationship between the lan connection and the motherboard. try replacing the cable, if that does not work then either your motherboard is damaged, or the NIC card is.

My problem is similar to some of the others listed here but slightly different. I am using a Sony Vaio laptop with Windows XP. I needed extra space for usb connections so bought a powered usb hub (I'd previously tried one without a power supply but nothing worked so the shop told me I needed a powered one) to use my wireless internet adapter and memory stick mainly. However, when I have it all set up and am busy using the internet etc, every couple of hours the internet/anything plugged into the hub stops working and a bubble message pops up:

Power Surge in hub port
A USB device has exceeded the power limits of it's hub port. For assistance in solving this problem, click this message.
If I click on the message before it disappears, it says:

A USB device has malfunctioned and exceeded the power limits of it's hub port. You should disconnect the device

The location of the device is shown in bold type .

-Unused Port

To renable the port, disconnect the hardware and click RESET. If you click Close, the port will no longer function.

If I disconnect then click reset, it starts working again, but the same thing tends to happen a couple of hours later if i'm still working. If I dont click on the bubble in time then the usb port that the hub was in stops working completely, cant even get my usb mouse to work in it.

I wonder if anyone can help.

I have a HP Compaq NX5000 laptop that runs without a fault apart from 1 annoying problem.

I have a 2.5" external HDD with a 60gig HDD installed. Every time I plug it in to the usb port I get the small popup error stating "Power Surge On Hub Port".

Now at first I thought it must just be my HDD pulling to much power but I can plug this into other laptops in the company and never have the problem. Can you suggest any reason for this and any way to rectify it.


A:Power surge on hub port

It may still be the HD drawing too much power. Most 2.5" hard disks ship with a two-headed USB cable to draw power from two USB ports, because the startup power exceeds the limits for one USB connection. I have several 2.5" USB drives, and with some systems, you can just use a single USB connector, others require both to get enough power to run the laptop.

Now none of my usb ports work. I have nothing plugged into them now or when I plugged the camera into the port. Is there an internal surge protector of USB ports that I can reset? I have checked the device manager and it states that all the ports are working but they are not putting out any power. I tired downloading the drivers but that did not work.

Please help.

Whenever I plug in my iPod to the computer I get a message that reads:

"A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device.
The location of the device is shown in bold type.

USB Root Hub (8 ports)
Unused Port
Unused Port...
Unused Port
Unused Port

Recommendation: To Re-enable the port, disconnect the hardware and click Reset. If you click Close, the port will no longer function."

I've tried plugging in my ipod connector into the 6 USB ports in the back of my computer but it doesn't fit. The only other thing I have plugged in is a mouse- that's been plugged in for years and I've had my iPod for a year and a half and it just randomly started doing this.
Please help me!

Recently I started getting the Power Surge on the USB Port message popping up whenever coming out of sleep mode and usually on reboots.  I have uninstalled, re-installed the USB ports and it is still happening.  Both USB 3.0 and the 2.0 seem to be working fine.  Is this a motherboard issue or is there another resolution?

So I needed to update my blackberry firmware so I went and purchased a USB Sync Cable.

This is the message I got :
Power Surge On Hub Port
A USB device has exceeded the power limits of its hub port.
For assistance in solving this problem, click this message.

I've clicked the message numerous amounts of times and it doesn't bring me to anything...



A:Power surge on hub port?

Some people have experienced the same kind of problem. The problem can sometimes be solved by disconnecting some USB-devices (if any). As for the message not working, I have no clue why it does exactly squat.

The discussion referred to below might give you some answers on the surge;

However I think your Blackberry tries to charge itself using the port interface, causing the surce. Perhaps some setting can alter this in the Blackberry itself?

Well I just got a brand new medion computer (4GB ram, 1GB nvidia graphics card, dual core i5 3.0Ghz processor, etc) about 3-4 weeks ago and have had no problems till now. The problem is when i bought the computer i got a mouse and keyboard which worked with it till about 2 days ago. I have 3 USB 2.0 and 3 USB 3.0 slots and. 2 of each type are on the back and the remaining 1 of each are on the front. Now, anytime i plug both the mouse and the keyboard into the back i get a warning message at the bottom right saying "USB hub port power surge" or something along those lines and neither device works. But if i un-plug them both and plug back in the keyboard, the keyboard works. I have tried restarting my computer. I have even tried turning the computer off, un-plugging it from the wall. Than holding the power button so it quickly flashes on and than off again (I hear this resets usb ports Link: Reset of USB port after probable power surge ) I than plug the computer back in and start it up but still neither devices work unless i unplug the mouse. I have also tried plugging in memory sticks and other devices and they work until i plug the mouse in beside them. Every now and than they un-expectedly decide to work together and than stop as randomly as it began. Any help or advice would greatly be appreciated

A:USB hub port power surge.

Well I would try another mouse. If everything else works I don't believe it is the USB ports. A mouse with a short to power could cause a surge.

My mom called me and said her computer wouldn't turn on-no light comes on when she turns on the tower. I went over there and found the monitor works (amber light on) and everything else that is plugged into that outlet, printer, speakers etc. I unplugged all cables from everything and even opend tower and made sure everything was plugged in tight in there but no go. If I push one of the buttons on the monitor (there are 3) it says that its in safe mode and to move the mouse or strike a key but nothing happens when I do and it turn off imediatly to an amber light The tower just wont turn on-like if it was unplugged. There was a thunderstorm last night. Could it have gotten fried?

Your computer could be fried or it could be your charger -- try using a different charger and see if that fixes the problem.

Hi, i've built a new PC with these following parts:

CPU: i7-6700K, 4GHz, Skylake, 8MB, Socket 1151

GPU: Sapphire ATI Radeon HD 5670

RAM: Kingston HyperX Fury Black 4GB, DDR3, 1600MHz, CL10, 1.5V x2

PSU: RASURBO Silent & Power DLP55.1 - 550 watts

CPU Cooler: Thermaltake NiC C4

HDD: SATA Samsung HD103SJ (1000GB/7200RPM/32M)

Optical drive: ASUS DRW-24BSST

My 12V voltage in BIOS is 10.848 V, which is extremely low, but my machie powers up and runs the OS (Win 7) just fine, but when I try to install component drivers, my CPU Fan goes insane and in a few moments I get a power surge reboot and a prompt saying just that. Researching, I discoevred that ASUS motherboards have a faulty anti-surge feaure that should be diasbled in BIOS, but I do not want to risk harming my hardware, that's why at the moment I am at an impase. I don't know if it's my PSU either, since the PSU calculator at outervision.com said I need under 500 watts for my machine, and just buying a more powerful PSU is a waste of money and also I risk to slow my hardware. My PSU isn't that old either and it's properly cleaned.

The CPU Fan is properly seated on my CPU and there's adequate thermal grease on the surface. Is there any problem if my motherboard is missing 2 screwes out of 8? because I had to buy standoffs to properly sit the motherboard, and I haven't yet installed does since I didn't see the point if my motherboard is stabl...

A:ASUS Power Surge New PC

First of all, I would STOP using the system until you install a quality pw supply. Having the 12V rail that low will cause stability problems and if the pw supply fails, it can take out other parts ie mb, video card, ram, etc.
Next what does the bios show for cpu temp?

As for having all of the screws/standoffs installed, as long as the board is securely mounted, it should be ok. You did not by chance install this board into a dell/hp or other big box case did you?

One other item I notice. That is a very low end mb. Asus is a fine mfg however that board is not one of their high end boards. It would be ok for a very basic build ie running office stuff, playing solitaire, etc. It is not up to the stress of running games or overclocking. I mention overclocking because you have a "K" processor with the unlocked multi. Paying extra for the K processor is somewhat a waste since the mb you installed does not allow overclocking via the multi [H chipsets do not support overclocking] You could OC with the base clock however that is not recommended.

Plugged my dig camera cable into usb port last eve and got the above msg. I then took the operation to my Dell pc which it always worked on, (the cable), and it did not work there either. My question is, has this power surge thing blasted my panasonic cable so that it no longer works? If the cable is damaged and I replace it, and I buy one of those powered usb hubs, will I be able to download my pictures to my pc? Would appreciate any thoughts. Thanks.
