Used wrong power supply for external hard drive...

Question: Used wrong power supply for external hard drive...

I did something really stupid.I accidently plugged an AC adapter into my external hard drive. It went on for a few seconds, I went to turn it back off and then pop! A bit of smoke and a smell came from the back.What did I do? Did I just ruin the hard drive completely? Or just the part that would turn the drive on. Are all my files on the hard drive gone?Please, anything you can do to help is much appreciated!

Hi one of the wires on my power supply for my Western digital external hard drive has broke. The power supply is a Ac input 100/240Vac 0.65 Max, Dc output 12vdc 2A, Model number DA-24B12. I am having problems finding a replacement, the only ones I can find are for laptops, and they are 4V upwards. I would be very grateful if someone could let me know where I could buy a replacement power adapter.Many thanksTaram

I have a 3.5" external hard drive that requires a (round) 5-pin power supply adapter. I lost the original, and bought a new one from an electronics manufacturer. The plug fits the slot, but I am not getting power to the drive and no signal is reaching the PC.

Without buying another power supply (the one I bought was hard to find - I had to go online and find a parts supplier, and I don't want to return it until I know what the problem is), how do I check to confirm whether the external drive is working, or that the external power supply and the drive are properly connected?
 

Answer:checking external hard drive power supply

IMO it would be much easier to just buy another enclosure and pull your drive out of the one you are using now. Install it in the new enclosure; good to go.

hello -

my power supply for my old external hard drive went kaput. i really need to be able to access my data on my drive, and i couldn't find just a power supply online; i had to i had to buy a whole new enclosure.

now heres my question: the power supply that came with the new enclosure is exactly the same as the old one, except for one thing:

the old power supply's output was 12v - 1.5A
5v - 1.5A
and the new one is: 12v - 2A
5v - 2A

will using this power supply on my old drive/enclosure hurt the drive? would taking the old drive out of its enclosure and putting it in the new enclosure ensure nothing gets hurt? i just really can't afford to lose the data on said drive, so any help would be greatly appreciated.

Answer:another external hard drive enclosure/power supply question

Putting the old drive into the new enclosure will be fine. The new enclosure might require more power than your old one simply because it's using a different design or different parts. E.g. Different controller, different manufacturer, different power needs for the controller.

Nothing to be worried about there. The same amount of power will still end up going to your drive.

First of all I am sorry of this has been answered somewhere, but I haven't been able to find it and I really need a solution.

My desktop does not detect and external hard drive that do not come with their own power supply. I have many externals that also plug into the wall and they are working fine; but whenever it is an external without a plug, i.e. the portable ones they are never found.

They do not show up in Computer Management, so it is not because I did not assign a letter to the drive.

I have tried various things, but I don't know what I should be testing for or looking for.
These externals all work on other laptops and other desktops perfectly fine so it is not the externals. When they are plugged into my desktop, they light up normally like they should, but the desktop never detects them. I have tried these externals with the different USB cable I have on hand, but nothing seems to work. It doesn't matter which USB port I plug the device in, it still gives me no response.

I am running a i7 860 on a ASUS P7P55D Pro.
If anyone has any information or a ideas please let me know.

Thanks.

Answer:External Hard Drives without their own Power Supply are not detected.

This is a rather common, but sporadic, problem. The issue, I believe, is that the USB ports on the problem PC are not putting out the specified power to run the drive. This is a problem typically seen in laptops.

IIRC, USB 2.0 specifications require the supply of 2.5 watts of power over a maximum of 5 meters at 5 volts (0.5 Amps). If you are ambitious you could test for the correct specs with a good multimeter.

The other possibility is that the problem external drive is requiring more power than is supplied by the USB specifications. This is not likely in your case because the drive works on other PCs.

One work-around, in either case, would be to used a powered USB port for that PC.

I lost the power cord to my external drive, and I'm too poor to buy even that. So I am doing this instead:
Above is the type of connector my external drive uses. As you can see it uses the same voltage (and amperage for that matter) as an internal drive. The main difference is only one ground wire, #4 is the ground wire. Internal drives have two ground wires.. I don't know why.

Anyway, a normal power strip in a computer is 2 blacks, 1 yellow, 1 red. The red is 5v, the yellow is 12v, the blacks are grounds.

I split the 5v red into two wires, and put them into sockets 1 and 2 on the image. I put the yellow into socket 3. And the ground into socket 4. Anyway, I seem to be getting a short circuit, as far as I can tell, none of the wires are touching each other.

I can close and open the DvD drive, so it's working a little bit, but I disconnect it quickly to prevent any damage to anything. I don't know where the short circuit is coming from, can anyone tell? It gets very hot super fast, I assume it's a short circuit anyway.

My best theories
1) Having two ground wires is very relevant
2) Splitting the one 5v wire into two prongs is apparently causing an issue (Though I highly doubt this).

Answer:Using Power Supply for External Drive.

Use all the grounds, 4,5 and 6.

I have looked around and around. I'm completely stumped.

I have a Lite-On external dvd combo burner. On the rear of the drive is the power connection, usb2.0 and l/r audio rca out jacks (red/white). Above where you connect the power cord is also a toggle on/off switch. During a move, this toggle snapped off. In the off position. I got to the card and the toggle switch is soldered to the card. No way to get in there (easily at least).

I haven't been able to find a replacement card and I'm reluctant to jam a paperclip (or whatever) in there wiggling it around and scratching up the card.

Any suggestions?
 

Answer:Power supply to external optical drive

Before this happened, I would unplug it from the back many times, & eventually get it to turn on. Before this happened the Lite-on drive would not play any cd I placed in the tray, no action.What do you think, a bad relay in the power supply, or a bad hard drive?

Answer:External IDE drive with power supply connected via USB 2.0 freezes PC .why?

If the External is faulty you could wind up with probs with the system itself. I would stop trying to force something into a system that may well have a current problem and see if I couldn't test it after I purchased a new usb wire for the thing at the very least.
Your External could very well be bad. Jazz

Thx Dace
 

Answer:Hard drive or power supply?

I'd put money on a software problem. Is there anything specific that causes the lockups? Like opening a browser or running a game? Without a specific trigger for an error it's harder to troubleshoot. Two things you can try: first is safe mode. This will load generic drivers so you might quickly identify if it's software or hardware. Use your error trigger if you've got one. Once you've done that, you can move on. Second is identifying the offending driver or component. For software, you must uninstall drivers one at a time. I'd start with simple stuff like mice and sound. Reboot after each uninstall, and again, use the trigger. For hardware you've got to physically remove things one at a time. Same deal, reboot after each, until you've defined the problem.

One more thing, have a look at the event viewer. right click my computer, select manage, and it should be there.

Hi,

I've just bought a new SATA Seagate 500gb internal hard drive as an upgrade, I currently have an 80gb SATA seagate as my main drive but this is full. I can see where to connect the new drive to my motherboard, however I can't understand how to connect the new drive to my current power supply.

Do I need to completely unscrew the power supply and all will become obvious?

I'm a little reluctant about doing that as it has a sticker on saying do not open, non servicable parts inside!

Any help would be most appreciated!

A mates hard drive was playing up and asked me for help. I ran Sea tools on the drive and was able to get it going so he could back up the data. He then bought a new hard drive. This would seem to be easy enough

The Pc will boot into Bios so I set the CD as boot pirioty, restart PC and it starts loading files and then just stops, nothing happening. Waited a 1hr to see if anything would happen, nothing. Replaced Ram with some of mine that I know is working, still no go, replaced the old hard drive to see if it would boot no go. Tried booting from Sea tools, same thing happens starts to load then stops.

The only thing I haven't done is remove and clean the cpu.

Im thinking it's a power supply problem?

System specs are Intel core 2 6400, 2.13Ghz, 2 gig Ram Windows 7

In Bios
VCore voltage 1.344V
3.3v voltage 3.244V
5V voltage 5.043V
12V voltage 11.985V

About a year ago, my one year old Compaq computer just died. I have no idea why and back then I didn't have the knowledge to try and figure it out. It literally went from being on in the morning before work and me checking my email, to coming home from work and I couldn't even turn the computer on.

To my knowledge, it was never turned on throughout the day and there wasn't a storm that day so I think a power surge can be ruled out. It was plugged into an outlet with a surge protector as well. Is there anyway to check and see if the Hard Drive is still good or anyway to "fix" it?

This was a $2K computer, yes ripped off by best buy, and now that I've started to fool around in the tech area, I can't accept it just dying. It had adequate virus and spyware protection as well. It was running on XP at the time, it was in the neighborhood of 180-200GB hard drive, I don't know what processor it has although I could look, and I'm not sure about the motherboard.

I'm thinking it's possible the power supply could have gone bad since I can't even attempt to turn the computer on. I don't believe it could be the hard drive but I don't want to rule it out although if it was the hard drive, it should at least turn on. Then comes a possibly fried motherboard. I think that could be the problem as well.

Please help.

I am trying to buy some large hard drives for older Dell systems (ie) Optiplex GX110, etc. I continue to be told by the sales folks at BestBuy and CompUSA that there may be a power supply issue with the legacy systems.

Answer:hard drive size and power supply

I doubt the difference between a new 7200 and old 5400 RPM hard drive is more then a few watts. The size, or capacity, of the drive has no impact as far as I know. If you are replacing an existing drive with a new drive then there will be no issue power wise. Even if you add a second drive I doubt you'll have a problem. I worked on many Optiplex systems and never had a problem adding a second drive or replacing the existing drive.

Now replacing a power supply in a Optiplex is hard er as most will not acommodate a standard ATX power supply.

One issue you may run into though is a BIOS limitation on the size of hard drive you can install. There are 8GB, 32GB, 127GB barriers. However DELL has BIOS for the GX110 that'll adds 48 bit LBA support which allows to use drives larger then 127GB if you wish.

I have a Toshiba 2.5 inch hard drive, MK1253GSX HDD2H04 F VL01 S.

Hey there, I've just received my third Caviar Black HD from WD after the previous two fried for reasons still unknown to me.

Before installing this third one into my machine, I wanted to hook it up to my laptop via a SATA-to-USB HUB so I could get the information on there before putting it in the desktop (I didn't have a Cat 5 cable). Of course I had to partition it first, so I was forced to hook it up to the desktop. However, I already had the hub's portable power source hooked up to it, so I just left it on top of the tower and ran a data cable to it from there.

And so, after I partitioned it, I hooked it up to my laptop, transferred the data, unplugged it, and then installed it in the tower using its native power source. Upon turning it on, it lagged significantly on startup. This had me particularly troubled because this was exactly what happened when the previous two drives gave up the ghost. Eventually, it got to Windows where I checked for the drive. It didn't show up.

I was about ready to hit the ceiling while trying to figure out why it was working one minute and then imitating the original drives the next. The only difference I could think of between using the hub/laptop and the desktop was the power supply. So on a hunch, I disconnected the native power source and hooked up the portable. To my surprise, it worked fine after that.

Naturally, one would take this to mean that the power source simply can't budget enough energy to keep the H... Read more

My dad said he came home the other day and smelled something "electrical" burning and traced it to the computer, so he unplugged it.

I plugged it in to test it, and got a loud horrible sounding beep (so loud i'm not sure if it came from speakers or the hardware??) and then nothing happens Won't boot up. I just hear a vibrating/sickly humming sound in the box that is in the back of the case, with a fan, and as far as I can tell the fan is still spinning, so the noise most likely isn't the fan. Would this 'box' be the power supply? I am guessing so since this is where the power plug goes in at. Also, if it is indeed the power supply, would this problem inflict damage on other components?

Now what? Would you experts trust this drive with a new power supply? Or should I crack it open and put the actual drive into a new enclosure? i feel like a hard drive I can't trust is useless to me. Am I too paranoid? Your opinions here will be greatly appreciated.
 

Answer:Hard drive power supply adapter burned up... now what?

Howdy,

Me personally would put it in another Enclosure as they are not expensive......also I might run a test on the HDD as well

Any help with this would be appreciated; I've asked a techie friend for some help but to only partial avail.About a year ago or so, my computer stopped being able to turn off completely.  I didn't notice it at first because I used to just leave the thing on all the time.  I wasn't terribly power conscientious, but one day, I noticed that turning the computer off (either from within Windows or by holding down the on/off button on the front of my tower) didn't cause the power supply fan to stop or the hard drive LED in the front to go out.   I also didn't do anything about it.Then, a few months ago, my computer started turning on and off randomly.  Holding down the on/off button would have no effect either way, and the computer would turn back on of it's own volition.  I took it to my techie friend and he said it was a power supply problem, probably a combination of the fact that my power supply stays on even when I turn the system off and the fact that my surge protector is out of date.  It's most likely been exposed to a few power surges unprotected.  So we replaced it with a spare that he had lying around.  However, even after replacing it, it still had the weird issue of not turning off even when the computer is shut down.  He checked the BIOS to see if there were any settings that were wrong, but he said it looked fine.  Of course, turning off the switch on the power supply still turn...

My PC went in for repairs after a catastrophic power surge - fried the power supply and the hard-drive. Both were replaced, but since getting it back, I get random freezes independent of what applications are running. I can rule out anything bad on the hard drive as there's barely anything on the new one, the new power supply should be more than adequate, and I have run Everest to check temps to ensure it's not heat-related - temps are fine, even quite low. I never experienced freezes before the repairs were done so I think I can rule out any issues with the motherboard. Any suggestions as to what I can try next appreciated!

Answer:Random freezes after power supply, hard drive replaced

Welcome to majorgeeks, ShazzerT.
Power surges can do a lot of damage, so rule nothing out. If you have just had it repaired by a reputable pc technition, then ask them to look at it, as it could be related to the power surge.
If only by repaired by a freind, and you want to test the rest, there are many testing and repair, software tools at majorgeeks downloads .

i turned my computer on the other day and soon smelled smoke. about 5 minutes later i heard a pop and my comp shut off. it wouldnt turn back on. i went to get it checked out and it was the power supply got fried.
apparently some tiny bugs had gotten into it. so i replaced it.

now when i turn it on it will freeze and restart itself within anywhere from 15 minutes - 2 hours.
i reinstalled windows to see if that would fix it but nope. then i replaced the hard drive (which i was planning on doing soon anyway) but this did not fix the problem. i also tried using a different video card to see if that was the cause but it still froze. also removed the ram modules to see if they were the cause, no luck.

now i am guessing that either the motherboard or processor is damaged, but is there a way to find out which one before replacing? the last thing i want to do is pay more to have someone diagnose the problem.

Hi!

I went to the lab to work on a digital photo project today and my external hard drive won't turn on! It is a Coltech and says "3.5" Hard Drive Enclosure" on it. It's one of the ones that has a USB and a power cord to plug into an outlet, and an on/off switch to turn on the power.

So I plugged it in, put the USB into the iMAC I'm using, turned on the switch... and it won't turn on... no power at all... normally it makes little noises when it turns on, but nothing.

I checked all the connections, both ends of the power cord and USB. I tried it in another iMac. I tried plugging a desk lamp into the wall to see if it was the electrical outlet... everything was fine...

HELP! ... my project is due on tuesday and all my photos and work are on my external hard drive!

Thanks!

Kaitlyn
 

Answer:HELP! My external hard drive has no power!!!

It might just be the power adapter or the enclosure that has died. You might be able to remove the hard drive from the enclosure and either install it internally in a computer or put it into a new enclosure. Most computer places sell enclosures if you need it in a hurry. Hopefully its not the hard drive inside the enclosure that has failed, in which case you hopefully have the all-important backups of your data.

My brother gave me his old WD 500GB external hdd a while ago.

Every so often it wouldn't be recognized, in which case I'd just unplug the power cable and plug it back in, but it would always turn on.

Then a week or two ago, the drive stopped powering on. I'd unplug and re-plug the power cable over and over again, and nothing. The drive's out of warranty, so should I take it out of its enclosure? If I do, would I just grab a SATA cable and plug it into my computer, try to have it function as an internal drive?

EDIT: It wouldn't have anything to do with the power cord, would it?

Answer:External Hard Drive won't power up

Sounds like the enclosure went bad on you.

Pull it out and use is as an internal drive.
should be a sata drive so just use a standard sata connector to your motherboard.

I have had a failure...I should have known that one day my external hard drive (Western Digital) would die, all the signs were there. The lights on the front gave out quite a while ago, for the last month or so the connection with the computer would be fine but then it would say that the file could not be found. Then last night, I think it has officially given out while I was in the process of transfering stuff to my new hard drive. Is there anyway for me to retrieve the information, music, pics etc? Is it simply a matter of replacing some kind of internal power supply? Because the external works just fine. Any help would be greatly appreciated.

Answer:External Hard Drive won't even power on

Some people have had luck putting the affected drive in a plastic bag in the freezer for 30 minutes, then mounting and using quickly upon removal. Get the data off quickly if it appears to be working!There was a poster looking to store all of his valuable data on an external drive because he did not want to use DVD's as it took too long.

What happens when you turn on a computer with the wrong voltage setting on the power supply. Can it damage more than just the power supply? I am also wondering if a motherboard has to be grounded in order to function properly. I have heard about people testing a motherboard outside of a case. Is this possible?
 

Answer:wrong voltage on power supply

Not sure about the wrong voltage part, but you can build a 'phone book' computer. Good for very odd troubleshooting. Set the motherboard on a phone book, hook everything up on a desk or suitable area and fire it up! A quick search tells me switching from 220v to 110v on the PSU with 220v power is potentially bad. It seems like I have seen somewhere that switching from 110 to 220 is ok if you have 110v power, but not sure about that.

Have a good one.

Got a Lenovo PC with Windows 7, when I tried to plug in my Hitachi external hard drive, it killed power to the PC immediately. I unplugged the HD, and power immediately came back on. This happens with any USB port, front or back. Tried switching cables, same result. The hard drive has an external power source, so it shouldn't be drawing too much power from the PC.

To make matters worse, after playing around with different ports, the mouse no longer works. When I plug it in, the light on the bottom flashes briefly, and that's it. I tried a different mouse. This time the light stays on but it still doesn't work. Did a system restore, no luck. Any thoughts, anybody? I'll be honest, I got nothin' on this one.

Hi facetaco and Welcome to TSF,

I'm going on a wild guess that the external harddrive is Bus-powered? (No extra power adapter)

If you plug a harddrive in that doesn't have an external power source, the power unit of your laptop might not have enough power to keep all hardware running. This is most likely the cause of the issue. One other possible reason is faulty USB ports;

Can you plug other USB medias into the PC without it shutting down, like USB sticks?

Wait, when you say you "removed it" where did you remove it from? From Safely Remove Hardware or from Device Manager?

The "KERPLONK" sound is a good sign - it means that Windows it at least recognizing that something is being plugged into the USB port. Have you tried running the Add New Hardware wizard in Control Panel?

Hi There,

My first post here and I promise I'll stick around and try help out others rather than simply disappear if and when someone's helped me out

My question concerns a Maxtor 3000LS 40GB external hard drive I bought recently. Naiively I assumed that it would get all its power from the USB cable and therefore I'd be able to use it in both the UK (where I am based now) and the US (where I will be based soon). However, when it arrived I realised that it needed an external power source. Serves me right for not reading the spec. properly I guess

Anyway, the power pack that it comes with splits in two i.e. the big chunky bit with the wire leading to the hard drive and the wire that leads to the mains. The hard drive came with two mains leads: A UK compatible lead and a mainland European lead. Now my query is, assuming that I could get hold of a US compatible mains lead, would plugging it into the chunky bit:

a) Not have enough power to do anything?
b) Frazzle the components?
c) Cause a rift in the space-time continuum?

I confess, I didn't pay much attention in physics class and so am a bit baffled by volts, amps, ohms, current and other flavours of electrickery so if anyone - preferably someone with knowledge of the hardware - could give any advice, then I'd be really grateful.
Many thanks,

Andy
 

Answer:Maxtor 3000LS External Hard Drive - Using International Power Sources

Look at the specs on the power supply. It may be a universal supply, many of them are nowadays. I just checked a camera and a USB 2.0 hard disk supply, both state 100V to 240V 50/60Hz, so they'll run either in Europe or the US.

Just got a Z710 with 16GB of RAM and an nVidia GeForce GT 745M video card.  It was manufactured 14/8/8. But Windows 8.1 complains on every boot the "The connected power adapter cannot supply enough power. Use of this power adapter may lower system performance". No one will do anything with this except let me return it. But Lenovo packaged the wrong power adapter so it is unlikely a new package will have the correct power. Why wasn't a power adapter included that would actually power this laptop? That is utterly ridiculous! Can anyone tell me which power adapter is the right one for this unit? Edited: Upon further digging it seems the supplied power adapter is 90W.  An nVidia 745M requires 25W - 30W so a 135W power adapter appears to be enough.  But does this Z710 have a UL-SDC power tip or a "Slim" tip?

Ok, I just bought this power supply. It doesn't fit into my case. So here's what I'm thinking: I put it in a place where it wouldn't be bothered, touched, anything like that, and just set it outside of the case on a platform. It's an Antec SmartPower 430W. What do you guys think?

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

Hi, I am new to these forums. Was hoping to get some advice on using another power supply for a new vid card that i got. The vid card recommends that I have a 350 watt power supply, but mine is only 200. I do have another power supply from an older computer just laying around, but that is also only 200. Is there a way to use that also? Even if it does sit on the outside of my cpu it doesnt matter. I dont have a really fast comp, old P3 400, so my budget is very tight. (thus reusing existing parts) Any help is appreciated. THX
 

Answer:external power supply for v-card

What Video Card are you talking about? It may be a bit much for that system, you might want to get something a little more matched to the system.

There is a way to do this but it is a little different than you are talking about. The best way would be to use the other PSU to power things like Drives and fans. Those devices can use the connectors already on the PSU. This may work if you can divert enough power to the second PSU so there is enough power left for the other devices and the Video card.

This could be very easy to do, or it could be very difficult. According to your level of electronics experience as well as the particular PSUs you have. Some PSUs will only power on if the mobo connector is attached(which can be circumvented)

You'll also need a way to turn both PSUs on at the same time which is not too difficult either.

First of all thank you for viewing this topic as the data on this hard drive is extremely sentimental.

Some of my greatest memories (such as my wedding), are on this hard drive, so I appreciate ANY help you can give me.

I have a 1.5 TB Seagate Expansion External Drive ST315005EXA101-RK, yesterday my foot decided to accidentally kick the power supply and a noticed a few minutes later windows was giving me the following error message:

"Windows was unable to save all the data for the file F:\$MFT. The data has been lost. This error may be caused by a failure of your computer hardware or network connection."

At first I didn't think much of it. I viewed the drive and all the contents were shown but no videos were playing. I thought it was a codec issue at first because I just recently nuked my computer. Most files don't open on the drive. The thumbnails for the pictures were still showing, some pictures I could still open, some text files were intact. Later on I made a small text file, wrote something in it, and saved it to the drive to see if I could still write, and it saved properly. I have never restarted my computer as I've read it may not allow me to see the drive anymore. I tried copying the files but windows gives me the "Cannot read from source file or disk." error. After a little while I opened up some pictures (possibly not the same ones) and only 20% of the picture I opened would be showing, the rest greyed out. After I we... Read more

I have a shuttle system with a small PS in it and want to run a RAID array off of it with 4 drives, which obviously won't fit in the system. But I can set them next to the system Ok and it will work. I'm concerned about power tho. Do you think I can get away with powering the hard drives with a stand alone bare PC power supply? What issues might I have?

I already figured out how to get the PS to come on by grounding the PS_On line. So I think this should work. Any comments?

Answer:Using a bare Power supply to power hard drives

Yes, tried it and all works. I thought that I might have to create a more local ground between the PC and PS to make sure the voltage levels matched but didn't need to. A shuttle system running with 5 hard drives and a DVD! Anyone beat that?

Hi. I just purchased a Lenovo Thinkcentre M91p (machine type 0266) which has an external 150w power supply. I purchased it to be used as a HTPC and i want to put a gpu and more ram in it. The problem is the power supply, all the ones i see people talk about have an internal 240w power supply. On the back of the pc is a DC in jack thats directly into the motherboard itself. I ran some calculations on power usage and the site i used said the recommended power supply size for the standard unit is 150w with a peak load of 123w. Adding the gpu alone pushes the peak load to 140w (nvidia gt730) with a recommended supply of 180w. My question basically is how can i upgrade an external power supply when all i can find is standard 150w external replacements or internal ones that wont be of any use

Hi all, I've decided to replace my old laptop, a ten year old  IBM Thinkpad X22 (yes really, those things don't die, they just keep going!) and replace it with a second hand Lenovo Thinkpad X220 I've just purchased from eBay. Being ten years apart I know the accessories I have for the X22 won't work on the X220 but before I order a second power supply I was wondering if that's also the same with the power supply? I don't know how much power supplies change from laptop to laptop and thought I'd just double check here before I order a second I can leave at work. I'm antipating issues installing software without a DVD drive so I'll probably purchase an external one - again just double checking for peace of mind but I guess I can boot from this and also watch DVD movies without any issues? Thanks in advance, and apologies for the basic nature of these questions ;-) Stu.

Answer:X220 Power Supply & External DVD RW Question

There are essentially two types of AC adapters. The old type that your X22 uses puts out 16VDC. The new type that your X220 uses puts out 20VDC. They're not interchangeable physically or electrically. There are several subtypes within the 20VDC adapter range depending on the power output, 65W, 90W, etc
 
The 65W adapter will power the X220. It's best for travel because it's smaller and lighter than the 90W. However on some systems including the X220 when using it the CPU may slow down in order to conserve power(*). Do you know the power rating of the adapter that comes with your X220? If you plan to use the X220 primarily when plugged in, then I'd suggest the 90W unit is better. 
 
As for DVD drive I don't see why you couldn't boot from or play DVDs. I can do both with an external USB DVD drive on my X61s.

Hi,


I have a Gateway GT 5082 ( Athlon 64 X2 , 2ghz flavor) I believe I have 2 problems if I want to purchase a decent video card. The stock power supply i believe is only 300W. Probably need around 400W to power a good video Card.

It comes with a PCI Express slot but even if I had the recommended power supply I really dont see an empty slot on the motherboard to put in the power connection from a new video card ( such as the nVidia 7950 GT ).


Do they sell external power supplies that I could run indepently of my computer and just power a video card? It would seem like a pain in the *** to replace the oem power supply so let me know what you think!

Yes I know there is an inherently 3rd problem the fact that I purchased a gateway haha... but just looking for some solutions here.

hi mehilton,
 
Welcome to Lenovo Community Forums!
 
You can check your system's Hardware Maintenance Manual and check (page 45)
   this is a Part list and upgrade option. You'll find the Power Supply compatible for your system and its part number.

You can call Lenovo Spareparts (877 4536686 and prompts 4....3....2)    about the part number if you're planning to purchase one.
 
Technically a Generic ATX PSU will work on your system but the problem is some connectors on a K410 PSU is specially made for it and a feature like the Power mode Ambient light will require a original K410 PSU
see this discussion.

 
Hope this helps
Cheers!
