Q: Need to replace an overheated power supply that died for my ...

I have a 6.5 yr old e9180t which the power supply died on me this weekend. The unit has an interesting history. The mother board was defective when I bought it and they had to finally replace it along with thousands of others. This unit coined the term inherently defective with google at the time. They rolled it our before really vetting it properly. When I looked inside the box when I first got it I noticed how crammed the interior was compared to my previous unit. This unit has always run HOT. After years of the heat build up I eventually just removed the side panel due to the heat. So when the power supply died this weekend I discovered another big design problem with this unit. For the first time I removed the top plastic panel . . . this panel completely hid and covered a vent for the power supply the whole time! The vent was completely covered with thick dust. I literally had to peel the dust off this area. I always used air to blow the dust way inside but since there was no vent visible I had no idea about this issue and never saw the need to remove the top plastic cover. So I plan to replace the power supply and have two questions. 1. First what is a good replacement? I see that EVGA makes these power supplys where both ends of the wires are plug in which seems like a perfect DIY approach. The current dead power supply was a Samsung 460watt HD642jj. I use two 27" hp monitors with this unit and work on graphics mostly during the day. I have i7 920 with a Radeon 4850 graphics card with 6 2GB DDR 3 = 12GB total memory along with a 640GB 7200rpm sata 3Gb/s hard drive. 2. Also will want to vent the top of the computer and need to actually put holes in the plastic cover to do so possibly or just forget the cover entirely? I think this was a very poor design feature since cleary Samsung designed the power supply to vent thru the top as well but HP never designed a vent for it with their cover??????? Since there isn't enough room to add another fan in this box from what I can see . . . is there any work arounds that folks have done to cool these hot crammed towers down besides removing the side panel? I do not want to buy a new computer yet since I have an i7 already and the memory is sufficient and not really too out of date. I might want a bigger hard drive eventually. For my needs it works fine. I tried migrating to Win 10 but it messes up so many things with my work and didn't see MS wanting to fix things much with it and back tracked to Win 7. I use and like Microsoft Office 2013 and that works well with Win 7. Windows 10 makes a mess of the viewer and problems with PowerPoint and so many issues. I think if I were to buy again I would have one built locally with more care with considerations to heat build up, no bloat ware, let me use Win 7, more usb slots in front for my wireless mouse and keyboard and other things I plug in from time to time, use all that wasted space for extra harddrive for another fan, more room so you can actually blast air to clean out around the processor, more vents on the side panels and above where the heat rises to. I spent a pretty penny and got many upgrades and I thought I was getting a well designed unit. I just don't think it was vetted and designed very well. I do see the return policy has improved since I bought. At the time I only had 17 days from the day I got it to test it out and return it back to them. Now they give 30 days which is a bit more reasonable.

After posting this I thought about the issue with the power supply and HP must have installed the power supply upside down and that is why this power supplied died and why this unit was always super hot. I just looked at the power supply and yep I think it was upside down. For years I have been plugging this in on the upper right hand side not the left hand side. The only person who has worked on this computer was the guy who was hired by HP to replace the motherboard after two months since the board was defective from the get go. I wonder if he had taken it out and put it back in wrong? I don't know since I thought HP and the guy knew what they were doing and I had no idea to keep a close eye on how the power supply should be. Unbelievable!

Hi all,

my power supply died two days ago. By chance, everything else seems in
order, except for the USB ports which act strangely.

I bought a new power supply and installed it. The computer boots normally
and the OS starts without a problem when there is no USB devices plugged to
the motherboard.

If I try to plug something to the USB ports while the computer is on, there
is no problem and all my USB devices work fine.

But if I boot with the USB devices plugged to the motherboard, the computer
doesn't even try to boot (nothing happens when I press the power button).

Someone have a hint?

If the USB ports are not working properly, should I change the motherboard (in case it blows up something else with time) or just disable USB ports and buy a PCI USB card?

Hi, this is my first post, so I hope I can explain what happened to my pc clearly. I have an older gateway 450mhz and recently I tried to power it up and nothing happened, like it didn't have power. So I reset my power strip thinking it just tripped the breaker, and it started to come on, I could hear it power up and then it just shut off again, no power, lights or any thing. so I plugged it directly into the wall. and the same thing happened, started to power up, and it was like it would reach a certain power level and trip some kind of internal breaker or something.
Hopefully there's someone out there that knows whats wrong and if its worth fixing..... Thanks alot for any replys

Presently have this power supply:

Antec BP500U ATX 12V 500W Power Supply


Computer overheats and shuts down. On checking, the fan in the power supply stopped working. Looking to replace the power supply with a different brand. The fan in this one was LOUD.

I'm running an Intel Core i7.

Does it matter what brand/type I replace the power supply with? (I see 550w, 600w, dual power. Should I consider any of these?)

Are there any recommended brands/models that keep it very cool and very quiet?

Old Power Supply: http://www.newegg.com/Product/Produ...ords&cm_mmc=KNC-GoogleAdwords-_-pla-_-NA-_-NA

It's a pretty by the book build. Last night though, I walked into my room and noticed the power off, and it wouldn't turn on. I opened it up, checked all the connectors, gave it another shot, and nothing.

My old computer had a 750 watt Cooler Master (http://www.newegg.com/Product/Product.aspx?Item=N82E16817171024) in it, so i took that out and tossed it into the new system while I wait for OCZ To send me a new PSU. Everything seemed great, I did my normal tasks for the rest of the night. When I launched Battlefield 3 though, the PSU actually makes a very odd buzzing noise. I don't remember this at all from my old computer. The red warning light doesn't go on or anything, it just buzzes. It also happens in Dungeon Defenders. The second I turn either game off, it stops.

Right now I'm back to basic tasks, but is this just due to the extra load from the new system? My old computer probably could have run fine off something much weaker than 750w (it had 8800 gt / Q6600), so I'm wondering if this it's just finally getting a workout or something. It has always run fine, I'm not sure why it would act up in the new comp. I'm sort of stuck until OCZ Gives me a replacement. Is it safe to run this thing?

Hi. This is the story. In the middle of my son using the computer, it just shut down. I came down to the room where it was a minute later, tried flipping the master switch on the surge protector off and on, then pressed to power button on the case. It started up. A few minutes later my son called me again because it had shut down again. The former trick didn't work. Here's what I've tried:

Flipping the I/O switch on the power supply both ways and trying to power up.
Unplugging the power supply from the surge protector and plugging it with another cord directly into the wall outlet. Then flipping that I/O switch again.

Nothing happened. Does this sound like it's the power supply?

A:Computer died!! Is this a power supply problem?

I`m afraid it does sound like the psu has gone bad.

However, the only way to tell for sure, is to try another psu, and hope that`s all it is.

I have a Lenovo Thinkcenter i7 M92 that worked a while ago and when I turned around to work on another computer, it apparently turned off and now the power will not come back on. The power button wont even light up, nor will the lights where the network cable plugs in. Have tried different outlets, different power cords. I am thinking it is a power supply issue but I cannot find a power supply to order. Any suggestions would be greatly appreciated.

Bit of a long story for this but bear with me.

I was playing a game this past sunday when my main pc lost it's power, after it died I heard what sounded like metal hitting metal within my case, I took my power supply out and took it apart to find what looked like a coil wrapped around a plastic tube, half burned, so I guess it melted itself off. It was my fault as the inside had tons of dust clogging the fans and vents. Luckily I had a backup for just such a problem, I borrowed the power supply within this secondary pc, it has a 1000watt psu(sli ready) whereas my old had a 600w(also sli ready), I figured it would be a more than suitable temporary psu until the replacement I ordered arrived.

However for whatever reason it won't work in my main pc, whenever I boot it up, everything seems fine but after so much time of being in use the pc just loses power. If I do nothing it will stay on, if I do anything other than idling it loses power. If I scan using MSE it always crashes around 7 minutes or so of scanning but spybot can scan completely, if I browse it tends to take a bit longer to crash (around 30 minutes more or less). I have ran a temperature detector in the background as I scanned and did other things and nothing ever went above 50C so I'm fairly certain that it isn't a heat problem.

To be honest I've been pretty lucky with most of my past pc's, I've had this one for about 8 1/2 months and other than a few random crashes this has ... Read more

My system has 3 HD's. The SATA is an add on, with a sata pci card, just for storage. The 2 IDE's are setup for dual boot with XP Pro on both(C:drive & D:drive). One is more for gaming, the other is for everthing else. Everything has been fine for several months until my power supply burnt up. I had set up a dvd to burn when I went to bed and the power supply died during the burn process. I replaced the power supply and now cannot get my C: XP to boot completely. I can however boot to my D: XP and access my C:drive and all of its files as well as my SATA storage drive.

On bootup, I select the XP installation that is listed first which is my D:drive, all goes well and evething works. If I select the second installation which is my C:drive all seems well... It shows that Windows XP is loading but when it normally goes to the screen that allows me to enter UserName and Password all I get is a black screen and it just stays like that. No error or reboot... nothing.

Would really hate to reformat(take about 2 days) as I had just got it setup the way I want it. Since ntloader does come up and allows selection would it be safe to assume bootini is ok? Is it probable that the death of my power supply could have cause corruption to kernel32.dll? What say you?

I am sure that you can located one in China for fairly cheep, especially since they are probably made there anyway, and then upon your return, have the original replaced under warranty.     Ask around, there must be a computer outlet somewhere that sells parts that can locate one for you in China.    It may be a knockoff, but it will get you by for your trip, just make sure the voltage/amperage match that printed on the original.

a few hours ago, my mom brought home a brand new Acer Travelmate 4603WLCi laptop. after connecting the AC adaptor to the laptop, I turned the thing on. it worked just fine, and the Acer ePower Management software showed 33% battery power and still charging.

I was playing Solitaire back then, only for like 20-30 minutes, when suddenly the laptop just died. plain died. without shutdown.

so I turned it back on, and it went back on. only for like a few seconds after the Windows XP splash screen showed up, it died again. this time, I can't turn the thing on again.

I checked the adaptor cable that connected to the laptop, it's plugged firmly. however, the 'battery charge' lamp did not lit. I disconnected the adaptor cable, tried to turn on the laptop, it didn't work. I tried removing the battery, re-installing it, then tried turning it on again, also didn't work.

so I re-plugged the laptop to the adaptor, and thought that it'd charge up. but after 3 long hours of (useless) waiting, it's still not showing any signs of life.

I assume that this is a power adaptor failure, because when you connect the adaptor to the laptop, the 'battery charge' light is supposed to lit and you should be able to power-on the laptop. but hey, if the adaptor fails, aren't I supposed to be able to power-on the laptop by just the battery?

well, that's all I can tell for now.
thanks in advance for any advice(s) given.

I live in Florida and we have had some bad storms lately with the hurricane having past us. Yesterday my computer booted up and shut down fine and worked perfectly fine all day. This morning it will not power on but, the green light on the back of the computer goes on solid (does not flash) when I plug it in. I have a Dell Inspiron 546. Do I need to replace the power supply? Would an external power supply from Best Buy or CompUSA work the same so I could get the computer working today? Any help would be appreciated, thanks.


I have already unplugged, waited and replugged. Still, green light is on but, no power.
Everything thing else in the powerstrip is on and working including my moniter and speakers.
After unplugging everything except the power cable, again, green light is on but, won't power on.
Checked a different wall outlet and same thing. Also unplugged and changed voltage switch back and forth, still green light with no power.

Any chances this is the motherboard or would it bee the power supply? Just trying to figure out what the problem is here.

Hi All!

OK, here's the situation, my brother in Florida . . . me in Ireland!

Do we understand? Ok, I can't see his system, he can't turn it on, long distance bills not worth the added hassle.

Now that I've got that out of the way . . .

His system died about a month ago, and my Mom is going through email withdrawals (surprised the Heck out of her, as she never would have thought she could come to like anything to do with a computer)! Anyway, money being what it is, nothing has been done about it. I suspect a blown Power supply, also that is the cheapest thing to replace. His current Power supply is 250w and i was wondering if I could get him a 300w or 350w that will fit?

Remember, I'm not looking for troubleshooting tips to try to see if blah, blah, blah. I've gone through all that with him, and he says he followed my advice (telephone support is dreadful, but at least I could curse him out loud for his lack of knowledge) so I am looking to see if he will need to replace just the Power supply (by buying him one) or if that is not the end of the problem, if he will need to buy components, like new mob, etc.

So, I am just going to start with power supply, ok?

current setup:

LC-250ATX power supply by L+C Technology
AMD-K6-2/500AFX processor
SIS 5595 PC100 mobo

I realized as i was over-clocking my CPU and checking my fans that my power supply fan died. Most power supplies now come with 80mm fans in the power supply case. But like all fans they die over time. Mine for Example was a Master Cooler 600W PSU with a 2 year limited warranty. But that Warranty Expired.

First off Remove the screws on the power supply case.

Please notice the warning signs on the PSU. There still is enough power and chemicals inside of it to electrocute you so be careful.

Second take out the old fan. As u can see its the same as a 80mm fan inside most computers. But it only has 2 pins for power one wire is red the other is black. chuck that fan in the garbage or if it works keep it as a spare.

Third Look inside to see if there is dust or corrosion. Mine was full of dust but i cleaned it. as u can see the fan sits right above all of the components.

Forth get a fan that u are not using or a new fan you just bought. You can fit 80mm fans inside the PSU up to 5-90CFM or more but yes it will be loud but efficient. For me i used a old fan that came with my case i didn't feel like destroying my 3 fan turbine that hugs my heat-sink. Also as u can see i Zip tied the wire you don't want slack in the power supply.

Last screw on the fan to the face plate of the PSU then screw the face plate back on to the PSU. And there you have it an power supply fixed or upgraded for further cooling.

Hello naturalphenomen,

Hello all,

My computer has been making a lot of noise lately, in fact it's been going on for probably the past 8 months or so. The first month I mostly ignored it hoping it would go away, which it did, then a few weeks later it came back and I decided it was time to investigate.

I have narrowed the problem down to being the power supply fan, mainly because it's very easy to hear and detect that it's coming from the back of my PC (and in that area). So I cracked the case open, unscrewed a buncha stuff, took the power supply apart somewhat so I could try to dust off the fan, but there was no dust to be seen. I dusted it anyway, removed some plastic pieces they had in there that seemed to serve no purpose, popped it back together, crossed my fingers that I had fixed it, but no luck.

The odd thing is that this noise will seem to come and go, usually it will be on jet engine sound level for ~2 weeks, then be relatively quiet for a month or so, every time I hope that it magically fixed itself, but now I've decided I need to do something about it.

The model is a SilverStone SST-ST65ZF, 650 Watt supply w/ PFC (whatever that means).

So on to my actual question. What I'm trying to figure out is, should I order the same replacement piece? Is this a solid piece of equipment and I just stumbled across a bad one originally? Is there a more ideal power supply with a quieter fan (in the same general price range, say <$200) that I should order instead?

It's safe to swap out/upgrade a PSU. However the PSU you select should be, at the very least to start, dimensionally the same. The Antec will not work. [See the attached thumbnails]
It's somewhat debatable as to whether or not you'll be able to locate a suitable replacement anywhere near 500 watts.

The other day, my Lenovo IdeaCentre H405 desktop "died". It looks like the problem is the power supply (a 280W PC6001). As long as I'm getting a new power supply, I thought I might as well get one with more power, since I believe the one I have has been reported as being somewhat underpowered. Also, I might want to be able to power a more capable graphics card that handles dual-display well. From "Googling" the PC6001, it looks like it's an ATX power supply. But, other than Max Power and ATX, I don't know what other specs to look for to make sure that a Power Supply is compatible. For example, on NewEgg.com, their selections also include: Modular, Main Connector (20pin, 20+4Pin, etc.), PCI-Express Connector, Haswell Support, +12V Railes, SATA Power Connector, CrossFire, SLI, PFC (Active, Passive, No), Fans (0, 1, 2, ...). What do I need to look for to find a more powerful (400W?) replacement. Thank you.

Brief history of problem:

All components transferred to new case with 300w power supply. 2 days later she turned on the computer and power supply blew up due to switch moved to wrong power setting (230 => 110).

I replaced the power supply unit (400w) for her and all was working fine. 2-3 days after this the computer will not boot. It will not even get to the post stage, no beeps, no nothing and nothing shows on the monitor, yet all led's, fans, etc are seen to work and you can hear the hdd spinup.

I have reseated everything ,cpu, vid, mem just to make sure and all are inserted correctly.

Could this be a residual problem from the power supply blowup damaging the cpu or mobo somehow? or could the new psu be the problem?

My computer simply stopped working one day and doesn't even power on. The only thing left for me to do is try to get a new power supply, as that is the only thing I can think could be wrong. Unfortunately, the power supply is no longer available at HP, so I have to go through reseller. But, even once I get the new one, I can't figure out how to remove the old one. Everything is so tight in that slimline case and I can't see how to properly get it out without dismantling the whole darn thing. Any chance someone has available a repair manual for this computer with detailed instructions? Thanks in advance!

My computer died this morning, shortly after powering it on. My monitor flashed a blue screen for a split second and restarted. The motherboard boot screen appeared but then it went black. Attempts to shutdown manually caused it to restart a few times before it stayed off. I opened it up and cleaned out some dust and noticed the processor heatsink was BLISTERING hot, even after it was powered down for several minutes.

My guess is my processor fan died, I'll start it up later to see if the fan goes or not. What does it sound like to you guys?

Since I do not know how to do this capacitor replacement (yet). I thought I would buy a new PS. However, I do not want to buy a Z800 PS since it seems to me to be a defective design. Can anyone chime in and tell me if the new z840 1125 watt PS will work with my older z800? I have called HP support and spoken with the correct support people on this and they were not able to confirm if the Z840 PS will work (fit) on the z800. The closest confirmantion I recieved was that if it fits then it should work. Instructions to fix the capacitors:http://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/Z800-power-on-issue... Same issue I am facing:https://www.youtube.com/watch?v=f563JGeoxaw On a side note, can anyone recommend a good service tech to make such capacitor repares in Southern California or insrtuctions on how to make this repair (with pictures). Thanks

I have a W540, which currently uses a 170W power supply (20V 8.5A) I also just recieved a docking station for a P50 which has a 230W power supply showing 20V 11.5A. The connectors look the same, but I'm hesitant to try the 230W power supply in the W540. Should this be ok to use the 230W power supply with the W540?

A:Power Supply Question - Can I use the 230W power supply with a W540?

230 watts is the maximum power supply, it only supplies the power needed by the computer. I sold my W540, so i can't test this for you. But i do the use the ThinkPad X1 Carbon with the 230 watts power adapter without any problem.

Yesterday, my primary HDD died, I/O error - not found, and only 1 month after my HP warranty expired.

So, I want to replace it with an SSD, but have never worked with them before. The biggest question on all this is, I run NovaStor backup on my PC and think I have a full backup on my NAS of the HDD that died.

Once I have an SSD installed and initiated, would I be able to restore the backup to the SSD, basically getting my PC back the way it was? Or do I need to do a fresh OS install and rebuild from scratch?


A:HDD Died, Want To Replace w/SSD. Have back up of HDD

you can restore from an image, but I wouldnt. your getting an ssd, speed is its biggest selling point; why saddle it with your old os and crap thats collected over time. start fresh and only install the essentials!!

My HIS AMD 6870 died. No video, no keyboard, no lights on USB units, and nothing. Substitute a older video card and keyboard lights lite, mouse connection lite, some USB units lite, no monitor lighting at all.

Pulled video card and replaced it with a ZOTAC GeForce GTX 550 Ti.

Obviously, could not remove the old video info and could not install the new. Computer now has the replacement card, keyboard lite, mouse lite, some USB lite, and no monitor lite. Currently set monitor to HDMI and graphics card to HDMI also.

How to I get this to light up the monitor so I can get the use of the computer again?

Need your help and instructions as to how to proceed.

Win7 SP1 64bit


Changed monitors and up it came in the generic vga, deleted prior software, and installed the current software for the other card.

A:Help to replace Graphics Card....Prior DIED!

If I read this correctly, you've tried three cards and you get no monitor lighting.
It's possible that a backlighting element within the monitor may have failed.
You can try the monitor out on another computer to be sure.

Hi there
Confused but not dangerous here. My computer was running Vista home basic SP2, and the hard drive seems to have died. I have a recent backup so that shouldn't be an issue, and I never did update to W7 prior to the crash. Want to do that now, not sure how to begin. Have bought OED W7 and a nice new 160 GB drive. How to introduce them to each other and promote a fruitful union?
ever hopeful

A:Vista Home basic HD died. Need to replace w/ W7 drive. help pls?

unfortunately oem software cannot be used on your system. It is only for a system that never had an operating system on it. The only hardware replacement you can make where you can use oem is the motherboard.

Hi all,

The laptop in question is a Toshiba Satellite A105-S4334. A few weeks ago, it got dropped right on its corner with the power plug still in it; the little metal plug of the AC adapter is now slightly crooked, and the power jack has a little chip off the plastic part of it.

Anyway, after this mishap, it worked fine for another 3, 4 weeks, and then suddenly this week, it's refusing to power up. Its battery has been shot for a while (can't hold a charge), and I've been using it with the battery out. Why the sudden refusal to boot?

I took the whole thing apart---minus the little chip, the power jack looks totally fine and cosmetically sound. Put the whole thing back together, taking care to check that plugs were snug---still no power.

Stuck in the crappy battery; booted just fine (and then shut itself down after like 2 minutes).

How likely is it that it's the power jack which is broken? And why did it take this long to crap out, if it IS broken?

A new one of those silly jacks costs over $20 on eBay, so I want to make sure that it's the jack before I just up and buy one. Of course, if it's the AC adapter that's broken, that would cost even more! Bah.


A:Replace the power jack or replace the adapter?

AND/OR inside the case the the jack is soldered directly to the motherboard. Is also possible that
1) It's already cracked
2) If not yet, it's gonna crack

So look to see what connection looks like between power jack and motherboard, If you feel u wanna/can re-solder yourself or the typically price to redo the whole power thing seems to run $125 parts/labor/warranty if you take it somewhere. So how much is it all worth to you?

Toshiba Satellite L305-5955, Ive taken apart and replaced power jack. Not directly soldered to motherboard. While still apart, and battery out/in, connected power supply and still absolutely no response. Power supply is NOT original, and slightly different specs, i.e original 19v..6.3A

current 19v..3.1A

A:Toshiba Satellite L305-5955 does not respond to power supply, new power jack

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

I picked up this Alienware 5700 off ebay to hopefully refurbish for my son but I'm new at this and still learning and so this thing has me baffled. The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.

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

Remove the laptops battery and try the AC power only. If the green light does the same, it still could only be a bad AC adapter, or at worst, a shorted laptop motherboard

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

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

Use a power supply calculator to get a accurate calculation of your power requirements.   Graphics card manufacturers have to figure a worst case scenario when giving power requirements.
Mod:  removed the Newegg calculator, which only gives a recommended psu size, rather than a power calculation.   The CoolerMaster gives both.

Hi, so I have had a powering issue with my previous power supply which was the Corsair CX600W so i purchased a newer power supply - the EVGA SuperNova G2 550W. I unhooked my old psu, hooked up my new one and the PC turned on and I turned it back off from the power button on the case. I also hava a boot drive problem so I unplugged the sata cables from my SSD and wanted to try to turn on the PC with only my HDD. I did this with the PSU switched off and the power cord unplugged. When I tried turning the PC on again the PSU made a clicking noise and nothing turns on. The motherboard Led's are lit up so it is definitely getting power but when I go to turn the computer on it just makes a quick clicking noise and nothing turns on. Any help is appreciated, thanks!

A:Power Supply makes clicking noise when I press power button

You may just need to drain the power off from the power supply and try again. Unplug the power to the power supply, press and hold the power button for 30 seconds, then plug it back in and try to turn on the computer again. If that doesn't put the old power supply back in and see if the PC works, or was the old one dead? If the PC works with the old one and not the new one then you may have gotten a faulty power supply.

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