I use a Seagate USB 3.0 external hard drive to do automated system backups on a weekly basis, using both Windows and Acronis. I have always left this drive on all the time, even though I only use it weekly.

I have read where some users power their external hard drives off between backups.

Any recommendations on the best thing to do.......leave it on or turn it off?

Thanks in advance.........

Answer:Is It Best to Keep External Backup Hard Drive Powered Off

If you can disconnect this drive when backups are not happening, you increase your odds of not having any viri or malware hitting the ext HD. Other than that, disconnecting and powering off ext HD saves some wearNtear on said device.

I'm about to order a little Seagate external hard drive for a friend to use as a backup drive. It's powered from the USB port, and is a USB 2 unit.However, my friend's computer has only USB 1 ports. I know that data exchange won't be a problem (although a bit slow) but will a USB 1 port be OK to power the drive?

Answer:USB-powered external hard drive question

Yes power output for USB1 or 2 is 5v and a max of 500mA per hub

Hello everyone this may sound like a very dumb question but I am interested in buying a USB3.0 Harddrive, which I want to be writing game footage on the fly to it. However is there any difference between read/write speeds of an Externally powered vs. Non Externally powered Hard drives?
Also could someone out there recommend a good 2TB USB3.0 External Hard drive with good Read/Write speeds for recording game play to.
Thank you!

Answer:Externally powered vs. Non Externally powered Hard drive

In general external 3.5 inch drives need power 2.5 inch drives don't.
Read write speeds are limited by the connection type esata, USB 3. USB 2. external power or lack of make no difference.

For reasons mentioned in other posts (dead computer) I am having to try to run more than one external hard drive on a fairly old laptop.
This laptop has two USB 2.0 ports. But it clearly struggles to cope with the power demand of external hard drives. Some of my external drives have a single USB connection, others have two, one of which takes power from the second USB socket (I assume this indicates that different HDDs have differing power requirements and that some need more power than a single USB socket can provide). This means that often I can only run one external device at a time.
So I am thinking of getting a separate powered USB hub. But a quick online check reveals that not all powered hubs are the same, and some of them can't cope with running more one external HDD. Can anyone advise on which powered hubs are capable of coping at the same time with, say, two external drives, or a hard disk drive and an external CD-writer?

Answer:Powered USB hub for external hard drives?

Thanks Lazarus .... but YMMV. Some of the reviews of this Akasa hub suggest that it may not be able to handle more than one hard drive. The reviews on Amazon tell a similar story about many other brands too, although the MaxValue 13-port hub seems to perform better than most.
Some websites suggest that the design of hubs varies: in theory each port needs to be able to provide 500mA, but in many of then only one or two ports provide full power and it is assumed that other ports will be used by flash drives etc which need little power.
I found a US website at http://www.brighthub.com/computing/windows-platform/articles/1756.aspx which reviews some models. But the problem is that detailed spec on power-supply is rarely provided in the descriptions of the hubs currently on the market. So any expert advice on the power-configuration of hubs would be welcome.

All other things being equal, is there any practical or appreciable difference between an external hard drive that is powered by a power cord/AC Adapter, vs. one that is powered entirely by USB/serial bus cable? For example, is there an advantage of getting one hard drive vs. the other, such as durability, power consumption, or heat generation, or are these differences too small for your average consumer to need to care about?

Because I'm looking at two seagate external drives. They have 2TB models for each. Can't really seem to see a difference aside from size and how they are powered.

Seagate #1 (Desktop Version -- uses power cord/AC adapter)

Seagate #2 (Portable Version -- does not use power cord, powered entirely by USB cable)

Note also -- I don't see an RPM listed for these hard drives. I guess would be the same? I'm not sure though. Any help on this would be appreciated.

Thanks

Okay I have a vista machine I built my self a few years ago. Recently the power supply died and I replaced it with a bigger better one. 600 watts instead of 400. Machine works great, however, now it seems that external harddrives that are not powered from an external power supply (2.5 inch western digitals I have) are not recognized at all when I plug them in. Doesn't show up in device manager, disk management or anything. Nothing happens when I plug them in. The lights blink on the drives but nobody is home. They work fine on every other machine I have. Now, I know the usb ports put out at least some power because my iphone mounts fine and charges, even my 5th gen ipod which is a hard drive, charges and mounts, all flash drives work.... Could it be the external western digitals are not getting "enough" power, do the usb ports get power from another line that i might have forgotten to plug in? I thought those ports were all powered from the main power line that plugs into the Mobo all the other functions of the computer seem to be just fine. I've tried all 6 usb ports on the back and get the same result.

Any suggestions on what to try? Am at a loss. the drives are passport western digitals, I have a 60 gig and 120 gig...
 

Answer:external hard drives not recognized/powered in vista

1.) What's the make and model of your power supply? It's possible that it's underpowered for your setup.
If the power supply is generic, how many 12V rails does it have, and how many amps are on each 12V rail?

2.) Have you tried the drives on a different computer? If that problem is solved after trying on another computer, it's definitely your PC hardware causing the issue.

Very strange issue here is happening here. When the laptop T410s is always off before it's docked, so once it's docked I press the power button and no image shows up on the external monitor.  I then open the lid of the T410s, press the power button on the laptop, quickly close the lid and it comes up.  I've tried different docking stations, power supplies and the issue still persisted.  I then tried another Lenovo T410 and it boots fine. Here's the kicker... When the T410s is not powered down while docked and only logged off, then undocked, and then powered down. When it's reseated into the dock and powered up it works fine. It then made me believe there was a Docking profile issue. I've removed the docking profiles and recreated them, since it that didn't work; I even set XP to allow us to manually choose whether it's docked or undocked.  This did not work. Is anyone else experiencing this or have the expertise on this subject? 

Answer:If laptop is powered off on dock, will not display image when powered back on.

I have a T410s with 2 external monitors that I always used. 1x24inch LCD connected using VGA to VGA and 1x26inch LCD connected using displayport to HDMI. It used to be fine until some intel grapics driver update a while back. So I come to believe is the driver fault and/or the internal graphic card lack of capacity. My solution is to setup the monitors the way I like is to change the BIOS to boot up from displayport, and when successful going into the desktop then disable the laptop LCD. Then connect the 2nd LCD, extend the desktop and setup the resolution. From that point on I must always boot up with VGA disconnect then after into desktop, plug in the VGA cable and it will show up fine. If I forget and left the displayport + VGA connected when I bootup, it will fail and I have to do the initial setup again. So something with the displayport/graphic card/graphic memory is making the T410s 'forget' or discard the displayport. or the 1900x1200 resolutions of 2x monitors overwhelm the graphics card memory and it had to made a choice or give up. Most of the time it just goes blank or flash on/off In your case, if you only have 1x external monitor you can just change the BIOS to bootup screen in VGA/Displayport/Dock and when in the dsektop, set to duplicate mode for both screens. Then download this utility called ultramon and use it to setup the extended display setting to your liking, save the profile on the desktop/startup folder. When your T410s bootup, int... Read more

My laptop HDD recently would not load windows. So i installed the OS on a different drive. Now, when i connect the old drive VIA USB 2.0toSATA it will not show up in My Computer. Disk Management will not show the drive either. The HDD is getting power, i can hear the disk spinning.

Answer:Hard Drive is powered, but does not show up.

Plug in and turn on the external USB hard drive
Right mouse click on My Computer
Left click on Manage
Left click on Device Manager
Expand the USB list
Find the USB device for your USB Hard Drive (the one that has no description)
Right mouse click - Uninstall
Turn off the external USB hard drive
Turn on the external USB hard drive and let it find and install the driver

Open 'Administration Tools', select 'Computer Management', click on 'Disk Management' and see if it can be seen here. If it does show here, chances are it doesn't have a drive letter assigned. If this is the case, right click on the drive, select "Change drive Letter...', and assign a drive letter to it.

If it was not seen there, go to 'Action' on the menu bar, click on 'Rescan Disks' and it should come up. If necessary assign a drive letter to as described above.

I have a Sabrent 2.5" hard drive enclosure SBT-EKU25 that I am trying to use with USB on a Windows 7 laptop. The drive works but stops doing anything for several minutes at a time. There are no error messages, it just stops... no flashing or steady light. A minute or two later it picks up where it left off as though nothing has happened. It will then run fine again for several seconds and then it goes back to "sleep". I am trying to use the drive to backup files and it spends more time sleeping than doing anything else.

The drive enclosure does not come with any drivers and is supposed to be plug and play. I have checked the USB drivers and Windows says they are up to date. I have installed a 60Gb hard drive from an old laptop in it.

If i plug the the drive into the USB port on my Windows XP desktop it works fine.

After building a new system with silence in mind, I noticed that the hard drive was by far the noisiest component. I purchased a quiet hard drive to act as my primary drive and am using the much larger and louder drive for simple file storage.

Under "Power Options" in the XP Control Panel, I set "Turn off hard disks" to 3 minites. So after 3 minutes of idle, this drive should power off and stay powered off until I'm ready to use it again. However, the drive randomly powers on and then 3 minutes later, powers off again. I have turned off indexing for the drive in the hopes that this would solve the problem, but it didn't help.

Does anyone know of a software solution that would allow me to turn off power to this drive until I tell it to turn back on? If I don't find something soon, I'll have to buy an external enclosure for it and only plug it in when I need it.
 

Answer:Software to keep secondary hard drive powered down.

Your antivirus probably scans it or windows update caches files to it or something. You could always disable it (take away drive letter) in Windows Disk Management until you need it. No data is lost, it just temporarily makes it inacessible to Windows. Then when you need it just give it a drive letter again.

Hello,

I have a Compaq desktop with an
AMD Athlon 1.1GHZ
128MB of RAM
a 16mb TNT video card
and 60GB HDD

I tried to reformat the hard drive because I initially had a virus on it - so the only means was to format it. The first time I reinstalled it successfully with a copy of a WinXP Pro cd, that came with a dell laptop of mine. BIG MISTAKE-- the computer tripped out and was asking for authentication. No problme arised yet, windows xp installed, and authentication was the only thing that was being irritating.

I commensed to reformat the hard drive with nothing in it except the OS installed, with a different copy of WinXP that did not come with my dell laptop. In the middle of reformatting, however, about 51% complete, I powered down the computer because I thought it would not hurt the formatting process, so I could take it back to the owner's house and finish up the reformatting process there, and at the same time be able to hang out at their pool. the old idea of "kill two birds with one stone" or something. >_< I feel pretty stupid. I hope you guys don't chew me out now, but yeah.

So I tried to turn the computer on again later on to finish reformatting. I pressed the power button and everything seemed to go right, until nothing appeared on the monitor. the monitor stays black, with an orange 'standby' light as if the computer was on standby.

Hi there

Intuitively one might think using Powered (from the mains) external USB HDD's would require more power from the computer as well compared with those small self powered units.

I've no way to measure this but I'm sure the small units might consume MORE power as the computer has to supply all the power for Disk rotation and the USB I/O controller.

I only ask this because I need to put two large powered USB units (both with 2 X 3 TB Raid 0 HDD's in each unit) on to a USB 3 Hub.
The two HDD units seem to perform perfectly well whether connected to the chargeable port on an HP laptop or the "non chargeable" ones.

The RAID 0 is powered by the HDD itself (internal Hardware RAID) --used RAID 0 for speed -- don't need to mirror etc - I've enough backup if the whole thing goes bonkers. !!

The files on these HDD's are serving music and video so not intensive used -- don't seem to have any problem streaming media from the laptop.

Any engineers out there - curious over what is the actual load (power wise) on the computer if a POWERED USB HDD is used compared to a Self powered one. Note the Hub I'm using is not also powered.

Answer:Powered USB HDD - vs Self powered USB -- load on computer ?

We can suppose that a portable HD enclosure that has it's own power supply doesn't draw as much current from the 5 volt supply provided by the USB bus.

On a purely practical basis it simply doesn't matter. There are hard limits to how much current a USB port will deliver. USB 2 ports are limited to 500 mA, which is why they can be so bad for charging smart phones & tablets. A USB 3 port supports up to 900 mA.

The load presented to the host is not relevant. The external device either works or doesn't.

My neighbor said he had the same problem when disconnecting his USB camera after downloading photos. The solution to his problem was to remove a recently applied microsoft fix. Unfortunately he no longer has a record of which fix.

Not sure if this is a microsoft software problem or if the disk is going bad. Don't want to buy another drive only to find out it is a software problem.

Answer:External (5.1 Powered) Speakers No Sounds

First thing, remove the Dell Service Tag number from your post. Dell considers this personal data. The Model number is not the Service Tag number, the Model number would be something like Inspiron 610, XPS8100, etc. (I used to work the Dell forums).

Is the "Speakers" (Realtek) set as default playback device?

As you have both High Definition Audio Devices (2) that suggests a possible problem. Windows only installs that generic, basic function, driver when the correct hardware driver is not installed. Disable the High Definition devices in the Device Manager. See if that makes any difference.

Anyone know of an external sound card, usb or hdmi, that supports surround sound and has a built in amplifier. I have passive speakers. I've been looking all over google but can't seem to find one that I can afford. I'm looking for something cheap, very cheap, like less than 100. I looked into the Creative Sound Blaster X-Fi but it doesn't have a built in amp, so I'd get barely any volume. Any help is appreciated

Answer:External Powered 5.1 Sound Card

with all due respect, how loud do you need the volume? A X-FI with a (for example), Logitech Z506 500w speaker setup will rattle your windows at 50% volume, and annoy the hell out of others around you

I've been using Creative cards since the mid 90's and the closest thing they ever had was the I/O console which simplified connection to external devices, but these days most soundcards, and even motherboards have optical out connectors.

What about picking up a receiver off ebay or second hand? Is that an option? Pioneer have some cheap receivers. Or some more obsure brands are often cheaper.

But, if you want loud sound, and you want that sound to be quality - not just disortion, trying to do that for under $100 might be a tad optimistic.

I'd be interested to know if you find anything other than an external receiver, that does a good job.

Good luck with the hunt.

So I have multiple external monitors. When I'm not usually all of them, I turn the ones off I don't need. I just press the power button on the front of the external monitor.

The problem is when I move my mouse, it will still go in the direction of the monitor that's off, causing me to lose my mouse, because I can't see it.

Is there anyway to prevent the computer from seeing the external monitor when I have it powered off? The external monitors are Dell U2414h monitors and the laptop is Lenovo x230 Tablet with Windows 7. The graphics card is intel hd graphics 4000. Thanks.

Hello,
I am looking at purchasing the Maxtor M01E100 External Hard Drive and am wondering if it has to be powered by the included AC power adapter? Can it be powered solely by USB? Or will I always have to be around an outlet when I want to use it?

Also, if you guys have any suggestions on other good external hard drives, feel free to post them. Thanks!
 

Answer:Can the Maxtor M01E100 external be powered by USB only?

USB ports can only supply a Max of 500 mA.
As it's a 3.5" drive, its certainly going to be around 1 to 1.5 amps required.

Even using a dual USB jumper to power it from two ports is likely to fail.

2.5" notebook HDD's have lower consumption, they can sometimes be OK on dual port supply but it's often touch and go on them as well. I have a 30 GB 2.5" external that works on some (but not all) PCs using a dual head lead, its marginal.

The Maxtor may not even be configured to use the USB power if its designed for a mains adaptor.

Using XP, I have an old 80G HD (IDE) in a powered case. The HD was taken from an older PC, for backing up data.
Today the inevitable happened I switched on the ext. disk and everything froze. If the autorun started at all, result, the same frozen computer.
Tried all sorts of ways without success, then took the HD out of its case and dangled it from an IDE cable in the computer.
On booting up chkdsk ran seeming to find all sorts of trouble over indices and too little free space to do something else.
And then XP ran normally, I was able to copy everything from the old HD which has 36G free. All its contents appear to be OK.
The unit has been taken out of service, but I would like to know what others think might be the cause of all this bother?
~~~~~~~~~~~~~ In particular:
(A)The HD itself going down?
(B) A failure of the case's internal hardware?
(C) Corruption of one index or more due to exiting this drive without first making it safe to do so ?
(I think (C) is the cause.)
Sudden disconnection with a pen drive from USB has not spoiled anything for me yet, and the HD when rigged on the IDE circuit in the computer is safely under control. But on occasions I have switched the power off at the case as a means of "clearing the deck."

Answer:Opinions please - trouble with external powered case or its HD?

on occasions I have switched the power off at the case as a means of "clearing the deck."
That has possibly been the cause of the problem, but it's not certain. It could be that the drive is telling you something - that it's time for it to be retired.

I have a 1TB external storage drive that uses its own power supply and connects to my laptop via USB 2.0 cable. For months I've had absolutely no problem out of the device, until the computer randomly decided to forget the device was plugged in. Now I'm lucky to get the device to be recognized by the computer at all, and when it is recognized, if I try to move anything to/from the device, the connection is immediately severed from the computer.

I use this device for my backup as well as holding on to things I would rather not get rid of. All my drivers are up to date, I've done all the Power Management checking and unchecking that I've read from other threads found via Google search, and still it won't work correctly for me. Any advice?

Answer:Self-Powered External Storage not recognized/randomly disconnecting

Providing you have done all the power options to attack the problem from the OS end of things, then you must consider that the drive itself is the problem. This seems likely since the drive has worked fine in the past.

The first suspect would be the USB cable, the connector on either end, or the port on either end.

The second suspect would be the hard drives power supply. These do go bad. If it is not supplying proper power then the drive will fail to be recognized correctly.

Try the drive on another computer. If it exhibits the same behavior there then you can narrow it down to one of the two issues above.

I have a few external (WD) drives.
Starting Windows 7 x64 whilst they are being switched on, mostly result in a hanging bootsequence.
E.g. I got a black screen and nothing is happening. there is no response on alt-ctrl-del, nothing.

The only solution sofar is to shut down the pc (power off), switch off the drives and start again.
After Windows is up and running again, switch on the drives.

Maybe this is a 'normal' situation and there is no real solution for it.
Have to live with it then.

It is a bit annoying though when I shut down Windows and forget to also switch off the drives.

I know this is very likely a dumb question.  I've ordered a combo IDE/SATA HD Enclosure.  Since that enclosure has IDE and SATA ports for connection of the hard drive being used, does Windows see the device as either IDE or SATA, or does it simply see it as one of a number of USB2 devices?  No burning reason for the question - just technical curiosity, which I suppose could wait until I receive and connect up the enclosure.

Hello, last night, I was having problems with my computer overheating while playing video games, and then I remembered, when it over heats, to make sure all dust is cleaned from your computer. So, therefore, this morning when I woke up, I took some q-tips, and proceeded to clean my computers fan, and RAM chip bus. Then, when I tried turing it back on, it wouldn't boot up. My OS would not boot up, and nothing would show on my screen. I checked for anything I must have unpluged, and re checked everything, but it's still not powering up. Does anyone have any suggestions? I think it has something to do with my RAM chip bus. SOmething musta burnt out. Any ideas would be perfect.
 

Answer:Seems like something isn't being powered up..

Qtips, and the motions of cleaning with the use of them, can introduce static electricity.
Go back to basics... the most fundamental setup you can create... power supply, video graphics port or card, one memory module, and a floppy disk with MSDOS or Windows 98 Boot/Startup, or if you have no hard drive, a boot to a CD-ROM such as Windows 98 or Windows ME. Boot to SAFE MODE if possible.
Does it boot? If not, you know you may have a problem. So change the optical drive, and try again./
If it does boot, change memory modules and try again. Still working?
Keep on adding one component at a time... then change to the hard drive, removing the discs from the floppy or opitcal drive.
Keep toying with the system to get something to boot, still keeping it as simple as you possibly can.
Progressively change and test. You can learn a lot in the process.

Question: CPU not powered?

Everything else is good. PSU fan spinning, power button working, GPU fan on (built in on EVGA GeForce GTX 750 ti SuperClocked), and it's plugged in by the PSU. The CPU fan isn't turning on either, yet it's plugged in. Sounds like anything fixable?

Thanks for any replies,
Joe
 

Answer:CPU not powered?

Need more information. Need make and model information on the Motherboard, CPU, PSU. Is the CPU fan a stock fan or aftermarket fan? Have you tried to remove and then re-seat the CPU? If you remove it, check for bent or broken pins.

When I was working, for an Authority, all PCs were powered up 24/7. When I asked the reason for this, the reply was 'less wear and tear on the equipment'. That sounds feasible to me, but should we treat our own PCs in this manner? Is it more/less expensive (energy-wise) to keep them powered up? I'm concerned that the fans stop working and the thing burst into flames!....or would that not happen?AngeTheHippyx

Answer:Is your PC powered up 24/7 ?

I leave mine on standby overnight. I believe this reduces 'wear and tear'. Some people will point out the risk of fire, but if you look round your home and count up the number of electrical items left plugged in, one more will not be of much consequence.

Question: under powered?

I'm not so sure about this one, might be worth it. I think my power supply may be insufficient for the amount of ram I'd like to use.

System:
AMD athlon 750
VIA Northbridge 100 fsb
ASUS k7m mobo
2x 128mb pc133 (should be 3x -- here's the problem)
300 watts
nvidia geforce ultra 64
sb16 pci
Maxtor 60gb HDD
WD 2gb HDD
XP Home
Canoscan USB scanner
Canon Printer on parallel

Alright, so, all three chips I have check out. I have used each independently, and run them through memtest86. The two I currently run are 8x16mb chips. Every time I try to run the third, a 16x8mb chip the original equip, it's all about the blue screen. I have had issues with other chips and compatibility. Kingston's 8x16 chip didn't like my machine's language, and had to step outside. My bios does not support registered memory, as I found out the hard way. A 4x32 ValueRam chip felt threatened. Do I give in and drop another sixty on a new chip, or can this chip be integrated into a community that needs a chip just like it to round out the neighborhood? Would a 450w ps help? A 400w? What gives? Does anyone know what I'm on about?
 

Answer:under powered?

Seriously doubt its a power supply issue. RAM uses very little power in comparison to other things.

Sound like its a RAM type issue, they just will not play together.

Question: Powered USB Hub

700mhz 256mb ram, Win XP Home, AOL8 BroadbandI have two USB ports and use them for the broadband modem and the printer. Can anyone tell me what advantage if any I might get from installing a powered USB hub, and plugging the printer and broadband modem into that.I read somewhere it might improve broadband speed?

Answer:Powered USB Hub

Printers and modems often do not work very well connected via a USB hub. They work even less well if both are connected via the same hub. You are better with the setup you have already and if you need more USB ports, buy a USB PCI card which will give you 4 or 5 NEW USB ports.Do you have a problem with your broadband speed? You can check and compare it if you click here and look top left aand click on "Speed Test".Brian

im making myself a sort of NAS box, but without the NAS for now lol

I will be mounting 4 3.5" HDD's in a hot swap box im making, and converting them to usb. For backing up purposes, without RAID.

Instead of having 4 usb cables coming out, i though about building a powered usb hub inside, and having just the one cable come out.

Just wondering if theres any part of my plan that ive not thought about!

Answer:How many HDD run off powered HUB?

Um...even if this works, how would your computer be able to address 4 different disks over a single USB cable? Short of writing your own transport protocol and special drivers to implement it, I don't see this happening....

Question: Powered USB 2.0

I am just enquiring about laptop/notebook computers. I have an application that states that a USB1.1 (2.0 recommended) full powered port is necessary. Some makes of notebooks actually list amongst their specifications, for example, 3 x USB 2.0 4-pin connector, 1 X powered USB 2.0 4 pin connector. So presumably there is a difference. Can someone possibly explain what that is and whether some models come with this, for my application (Meade CCD astronomical imager), necessary powered USB 2.0 port.

Answer:Powered USB 2.0

however, I am not 100% sure about this

I've been using a USB-powered hd to transfer files between my computer and media player. All of a sudden my computer won't see it anymore. The media player still sees it and my friend's computer running XP sees it, but mine won't. I've done "Search for new hardware" but got nothing.
 

Answer:Win 7 Won't See USB-Powered HD

It could be that on the computer that doesn't see it, Windows has simply failed to assign a drive letter to it.
This is not uncommon with external hard drives, even when the drive was previously assigned a drive-letter.

If that is the case, it's a simple fix.

Plug the drive in.
Now go to Control Panel >> Administrative Tools >> Computer Management.
Click on Disk Management in the left pane.

In the right-pane, all the connected drives are represented by a horizontal ribbon.
Look for a ribbon that's the same size as your external drive but has no name.
Right-click it and choose "Change drive letters & paths".
Click "Change".
Pick a drive-letter from the drop-down box, then click 'OK'.

Question: Powered USB hub

Apologies for what must be a very simple question. I'd be grateful if someone could tell me the advantages of using a powered, rather than a unpowered, USB2 hub. Is it just a matter of supplying necessary power to a particular device? If so, what devices would need one? Would using one if it isn't actually required be OK?Many thanks.

Answer:Powered USB hub

Deininately preferable.An unpwered hob relys on the PC power supply, which with some devices -a scanner say can be considerable and affect the computers performace. It does not matter too much for card readers or mice etc.,More over even here if devices not being used are left plugged in they will all be havine there 'pull'and can actually stop the msachine or at least not read.The rule here is if you are not using it pull it out and if you can power it separately.

Recently a friend's forum has been hacked, he's been able to recover most of it, and there's just 1 problem left. The "hacker" left a message on an "annoucement" that can be seen from the top of every forum section - can anyone please tell me how that can be editted or better yet, removed?

Thanks for the help in advanced - I've been through the control panel for a bit now & haven't figured it out.

This depends on exactly what the "hacker" (most of them are mere script kiddies) has done. Could you post a link?

Just got new Amazon Basics A150's. Very nice for the price. Instructions did not say if it is ok to leave speakers on all of the time or if they should be turned off. I recall reading somewhere that they should be turned off. Doesn't seem like it would make much difference but thought I should ask. Thanks.

Answer:AC Powered Speakers

I leave mine turned on all the time. I pull the AC plug out when I go on vacation or away for a few days.

My aunt came over and usede my computer today, and she improperly shut it down like three times in a row. Now, no sound will play and this is one of the error messages I get. "Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly"Also, the bar with the minimize and close button have the classic "98" look (the computer is new though), and I cant get it back. A few months ago, I shut my computer down improperly and got the same problems. But I had just gotten the computer so I just re-installed XP and it was fine. But now I have a lot of documents and and programs that I dont want to lose. Can anyone help me with this? Thanks!

Question: Powered USB Hubs ?

Hello,

Thinking about a new HP Envy 750xt desktop PC.

Only seems to come with 4 USB Ports, unless there are some on the back also.
Don't think so, though, but can't find a pix of rear.

Anyway, I have quite a few USB gadgets plugged into my present PC, which has 6.

If I get one or more powered USB Hubs to allow me to use what I now have on this new PC, am I likely to run into any problems ?
Caveats ?

Is only 4 more or less a standard these days, or is HP really penny pinching ?
How's the rest of their quality these days ? Opinions ?

Thanks,
Bob

Answer:Powered USB Hubs ?

I don't know the typical number of USB ports for a new computer now, but I've used a powered hub for years with my desktop systems and have had absolutely no problems with the devices I connect to them. These include portable hard drives for backup, connections for managing content on usb flash drives and mp3 players, and charging for the latter. I believe many of the caveats for hubs were directed at the non-powered ones.

I've had my PC for at least 6 months now, and it has worked fine.

The other day, when I went to turn my PC on in the morning and it would power up for a few seconds (fans & hdd's whirring), before shutting down. It would automatically attempt a restart within a few seconds, but the same thing happens. I opened the case and had a look, nothing seemed out of place. I have tried it a few times since, and it can sometimes come on for a few seconds, and sometimes it will boot to windows and stay on for a few hours before shutting down again.

In a nutshell:

It powers up for intervals ranging from a few seconds to a few hours.
I haven't changed anything in the system.
I have tried a different socket & cable.

I have ordered an Arctic Power 500W to replace my stock 300W, but I'm not wholly convinced it will solve the problem. Anyone got any other ideas, I'll take any simple-stupid suggestions, in case I missed something obvious.

A common answer I have googled is CPU overheating - I highly doubt it is the CPU overheating in this case, due to it first occuring within a few seconds, and the PC staying on for a few hours at times.

I have noticed the USB which I use for my mouse freezing during the longer stints that it is working, which makes me worry that it is the mobo, but the problem occurs whether plugged directly into the mobo, or using the case USB at the front, so this may be a symptom of a larger problem.

Thanks for any help... Read more

Hi. I am having problems with USB devices freezing or not being powered at all through my USB ports. I have been looking for an a/c powered hub (USB 2.0 is fine) to power game controllers and the like (such as the Razer Tartarus/ Saitek X52) - they freeze up when I use them together via the PC's USB ports.

But I can't seem to find one that's recommended. Nothing will ever get 100% 5* reviews of course, but comments (on amazon.co.uk) such as 'this device burnt out my motherboard', 'lasted six months then stopped working' and the like are not to be taken lightly! So any recommendations welcome.

Thanks

Answer:USB hub, a/c powered. Recommendations please?

Only obliquely addressing your issue, but I've been through the same issues in the past and found out that it was really driver issues not a lack of 5V power. With a high-end rig like yours, I suspect you are solving the wrong problem - just my 2?. Have you tried a typical cheapo powered USB block that runs off your PC?

What is this? When running AC powered the fan keeps running all the time. When I unplug the power connector it stops after a while and turns on occasionally. I already changed some bios settings for testing purposes (no succes). OS is Windows Vista SP1 fresh install. I checked the power and chipset drivers in the Lenovo update utility.

Answer:R61 fan ac powered on all the time!!

Hi! I have the same Problem. But the fan doesn't run all the time, though it runs ever 30 seconds and it's annoying. The CPU-Temps are between 33 and 35C. The fan starts between 35C and 36C so there is no need for cooling.Are there any solutions?I know tpfancontrol and similar programs, but i'm looking for alternatives. Maybe a Bios-Update (@Lenovo)?! System is a R61 with T8100, IGP...newest BIOS (2.21). ThanksHeadMessage Edited by Head on 10-28-2008 08:15 PMMessage Edited by Head on 10-28-2008 08:16 PM
