3 loud beeps, dead power supply?

Hello,
My boyfriend has a HP Pavillion Dv2000, when he tries to turn it on, the lights come on, it beeps loudly 3 times then nothing happens. I'm thinking either the Power supply is broken or his hard drive has had it.
I've done alot of hardware support for PC's but never laptops so I'd really appreciate is someone could help me work out what is wrong with it.
Thanks <3

Please identify your notebook/pc with more than the series number. Look at the base/rear/side of the notebook/pc at the barcoded sticker. Post items numbered 1 and 2 on the following image.
Post the installed operating system version ( and whether it is 32 or 64-bit)
Try a hard reset:
Remove the battery and unplug the DC power adapter.
press and hold the power button for more than fifteen seconds.
plug in the DC power adapter (leave the battery out for now)
press the power button
Best regards,
erico

S5-1554 Dead - power supply?

Computer found dead. Tried start button, no response. Followed hp troubleshooting guide: power supply has solid green light, and when paper clip placed across p1-17 and ground, power supply fan came on. However, when reconnected and push start button absolutely nothing happens. Once, all fans started to spin up for about one second, but stopped. Troubleshooting guide says if power supply fan comes on when the p1-17 to ground connected, the power supply should be good, and should then consider motherboard, memory, other causes. However, I'm skeptical. My gut still says it is the power supply. I have an older computer that died but has a good power supply that wouldn't fit, would it work to connect to see if it would power up just as a test? Other thoughts before starting to swap out parts as diagnostic?

Grumpy44, welcome to the forum. I agree with you that it could be the PSU. I have heard of PSU's working using the paper clip, but still not being good enough to power the computer. If you try to use your old PSU make certain that the ATX Power connector is correct.

Dead power supply fan

The power supply fan on my 2002 Quicksilver Dual 1gig G4 just quit and I am obviously concerned about the ramifications. I've read a few posts in different places about fan replacements but not sure I am up to that. Does anyone have any advice / cautions about power supply replacement?
Unfortunately this is my only computer and I can't really afford the downtime if I take it somewhere. I have reasonable confidence in my ability to do the work (I've added hard drives, replaced the cd drive, ram etc.). Any tips and especially a lead on a good (inexpensive) hardware source would be appreciated.
Thanks,
John

You'll need to remove the power supply from the computer and open it up to access the fan. Installing the new fan may involve splicing its leads to the existing ones attached to the circuit board. Beyond the fan's physical size, you need to match its voltage rating and output (measured in CFM), so that you buy a suitable replacement. The fan's noise level (dBA) should also be considered, so compare the specs on that. According to the info on this page, the fan's specs are:
Protechnic 80x80x25mm MAGIC (made by Sechang Micro)
12 Volt, 0.24 Amp
38.27 CFM, 3000 RPM (max), 29 dBA

Suspect dead power supply -- next steps, recommendations?

Hi all!
Our 17" iMac won't power on and I suspect it's the power supply (I tried different outlets and power cords). What should my next steps be? For example, while browsing I saw mention of LED indicators inside the unit. Is that the next logical step?
I don't necessarily want to continue using the iMac since I have a much newer MacBook Pro that I can use instead. However, I would like to get all my iTunes files off the iMac (I have a backup that's two months old, but I've purchased a lot of music/apps/videos since then). So if it's easier/cheaper, I'd be open to suggestions other than fixing the iMac. For example, can I pull the hard drive from the iMac and get some sort of external enclosure so that I can plug it into my MacBook Pro to copy the files off? If so, what sort of enclosure would I need for the iMac's hard drive (links?)
Thanks so much in advance!

Good old Apple forums. My iMac wouldn't start up and the first post on the list this past Thursday was this thread!
The machine had powered itself down twice and the last time I couldn't start it up. I did do a backup the night before.
I did the LED test all the way thru. Nice to learn that one. After #12 indicated my logic board needed to be replaced, I made a Genius appointment for two days later. There, Andrew at the Walnut Creek, CA store opened up the machine, saw that the condensers were fine and sent the machine upstairs for a new power supply. He said that sometimes the LED test will indicate the logic board, but most of the time it's the power supply. $85 each for the part and labor = $170. Much cheaper than the alternative.
Now that was one of my better Apple Store experiences.

Dead Power Supply and LaCie Portable HD?

Here's my problem:
I coordinate a lab that has 8 400-MHz G4's. Four of the computers have just died over the past few months; no power at all when trying to start them.
I've already tried changing batteries and pressing the PRAM button, but that hasn't help. So it seems that there may be a problem with the power supply dying.
But here's the catch: It seems that the computers lose power when I connect a LaCie 80 GB portable Firewire hard drive to them. I was running one of the G4's today when said portable hard drive attached. I turned the computer off, then tried to start it up again. No power!
I know this has to be more than a coincidence, since it has happened once before. And now I'm thinking that is probably why the other computers died too.
Has anyone else had this problem occur? Or is this just my imagination?

Is the LaCie drive able to work with any computer for a sufficient period of time?
It sounds like there may be an electrical problem with the external drive that is causing some damage when plugging it into a computer's firewire port.

Dead power supply for a srw2048 switch--options?

We have an SRW2048 gigabit switch and it no longer is powering up. I tried multiple cords and outlets just to make sure. Last year 1 of the ports died, who knows if that was a sign the switch was dying.
Anyways what are my options? Is this just e-waste now?

Sorry it's toast.

Power supply fan dead - help? (400mhz AGP G4)

Hello!
Unfortunately, my PowerMac G4, a 400mhz, AGP Sawtooth model, has a dead fan.
Over the last few weeks, I've noticed that my G4 has been running quite hot. I figured it was due to the hot dorm room that it's being used in. Then, I noticed that when it booted up, it would occasionally make a vibrating, or rattling noise - I figured the fan was wobbling. Since air was comming out of the fan opening at the top, I didn't worry about it.
Today, I used the "Temperature Monitor" widget to check the temperature of my SMART Hard drive (the G4 itself is not sensed). It was 133 degrees!!! This is the bay on the back-right, just under the CPU fan. I looked at the fan again - not much airflow. I pulled out a flashlight and pointed it in, and the Fan that's inside the power supply unit is dead.
So, how can I fix it? It's far far too hot, so it's not usable until I can cool it off. The first idea I had was to take a particularly powerful desk fan, and make a paper "tube" that connects both to the G4 and back of the fan - so it'll pull the hot air out. Needless to say, this is not a good log-term plan as it's easy to fall apart and will have leaks, but it works for now. I realize you can buy power supplies, but for ~$100, it's far too much for the old G4.
Second idea: The fan is inside the "non-user servicable" power supply, but it's also next to the back of the G4 - right inside what appears to be a panel that holds the power supply in. At the very least, I'd like to make sure that the cable is attached and not loose, but I have to open the back. Is that possible or safe? If so, can I replace the fan?
My third idea was to attach an extra fan to the inside of the G4, on the outside of the power supply - pushing in. Unfortunately, the IDE cable from the DVD drive is in the way, and there's not much room for a fan. Plus, there's no fan power supply. Is it possible to convert an ATA power plug (there are 7!) to a fan-power supply? I'd require a small circuit and a lot of resistors, obviously! If so, what would I need to do to convert it?
Thanks a bunch,
-Dan
15" 1.67 Powerbook G4 (Jan 2005), 400 mhz AGP Sawtooth G4 Mac OS X (10.4.8) 4G Clickwheel and 5G Vid iPods, 2G iPod shuffle

Thanks!
Interesting, this "Piggy back power adapter" will allow me to plug the fan into one of the ATA/IDE cables? Or do you mean the extra port on the power supply? (it has one plug for the outlet>G4, then another to support something like a monitor or similar) The G4 has a DVD burner, but no ZIP drive, so this is quite do-able if it uses the ATA power.
When you say "lower rear", do you mean at the bottom? Below the power supply, to the right of the PCI slots? If so, this is the inflow for the CPU fan! I can understand mounting it outside the current outflow-vent for the dead power supply fan, although I'm not sure the best way to proceed with attaching the fan.
Another question: what tools and supplies will I need? I may need to remove the plastic cover on the back of the G4 - the one that is outside the power supply - as there's a gap between the gray plastic and metal chassis that lets air from outside the machine come in. The screws for this cover use a funky, hexagonal screwdriver. If I need to take this cover off, what kind of screwdriver will I need? Also, should the fan not include screws/etc, what's the best method to attach it? Glue?
Secondly, to cut a hole in the G4, will I need some variety of drill? I don't have one, so i'll have to borrow one... Since there's nothing in the ZIP slot, I can run a cable out through here (assuming it's long enough), and make a new bezel to keep the airflow inside intact.
Ah! One other (somewhat related) question: my USB 2 card includes a power adapter, for use when several un-powered devices (flash drives) are attached. It works just fine with a flash drive and a small media reader, but it's slow to sense the drives - I think it's low on power. Unfortunately, this power plug uses the same variety of plug as the floppy disk drives found on many win-boxes - of which the G4 possesses none. Is there an adapter/cable for this purpose?
Thanks, this is a HUGE help, I appreciate it.

IMac 700SE - power supply dead? can i get a new one?

well the power went out last week, and when it came back up my iMac did not
right now, i plug it in, hit the power button, the power light flashes, i hear a click (about a half second later), then it just goes off and the power button stops responding it to anything, i unplug it, plug it back in, hit the power button and the same thing happens, to me this sounds like a dead power supply as i have had this happen on a few PCs and when the power button stops functioning that to me sounds like its the power supply overloading, and in this case meaning its dead
now i don't really want to spend the money on a new computer as this is only used by my mom every few couple of days for email/IM/web, so does anyone know where i could get a replacement power supply? (i think) its a sliver shaped board that attaches to the main board and makes me think that i will never find a replacement unless i buy another 700SE iMac off ebay

nope, didn't help, nothing changed with the new battery
though i did notice that it booted when i didn't power up the drive (no power cable to it), but that has nothing to do with the battery, i also tried pressing every button attached to the board and nothing helped, so to me it looks like the power supply can't spin up the hard drive (the drive is good too, its in my other comp right now)
does anyone know how compatible the 400Mhz iMac is with the 700Mhz parts wise? i'm suppose to be getting a 400Mhz iMac soon, and would like to know if i could swap out the logic board on the 400 with the one from the 700 as that 400 one has a better screen and working power supply, but i would like the nice speed boost

Exploding Power Supply

Last week the power supply of my 9 month old Mac Pro exploded with a huge bang. I was really scary. No visual damage, but the whole system is fried.
Let me give you a summary of the history:
first repair - Audio failure --> Logic board replaced
second repair - Mac was dead --> power supply replace
third repair - Mac was dead --> no problems found
fourth repair - Power supply exploded --> Logic board, power supply, etc is going to be replaced.
I called Apple and they want to repair my Mac Pro again. My question to Apple was: "How many times do you have to replace parts until I get a new Mac Pro?".
I'm really sad with the quality of my Mac Pro. It's a great system, but it's not reliable. Luckily I've purchased a MacBook some months ago, but I need my Mac Pro to do my job.

Looks like I'm joining the exploding PSU club. I powered down my Pro after work last night (I usually leave it on all the time) and when I came into the office this morning and pressed the power button I got a flash of bright white light from within the case in the PSU area and a loud snapping noise. The thing that I'm not sure about now is how the repair's going to go. Since I work at a University, I have to take the machine back to Tech Services and I'm just praying that I don't get personnally stuck with the repair bill.
Oh, and I've popped out my 3 data drives -- I'm not sending those to tech services with the machine!

Can't seem to find a power supply on the apple site

Hi there,
Could someone direct to where I can buy a power supply for a 23" Aluminum Cinema Display? Mine unfortunately has passed away and I can't find that part on the apple site. Have a meeting at the Genius bar today but a friendly salesperson told me they don't have them in stock. He also didn't know the warranty so I figured maybe the "Genius" would know. The polite and wonderful apple telephone service woman couldn't really help either.
Regardless, I'd like to know what they cost just in case I have to end up buying one. My dead one is 15 months old.
Thanks!

Thanks for your help. I find it very odd that you can't just order one. Regardless, the apple store is ordering one and should have it in a week or two. Fortunately I use two monitors so getting by should be simple. Also strange that they want the broken one back even though it's out of warranty and I'm paying (only $65) for a new one.
Considering what I now know about how difficult it is to get a power supply I'll probably never go to a 30" display because if the adapter broke on that, I could be out of business for days.
Search words to help others in my situation: Power Supply, Power Adapter, Dead Power Supply.
Best,

IPod HiFi A1121 power supply unit

Hi there,
I have an iPod HiFi A1121 and am aware it is discontinued. My power supply unit is the problem with mine, but due to the fact it seems quite complex and there are 3 different output wattages on it, it doesn't seem to be something I can just find a similar one of. Does anyone have a broken HiFi that they are prepared to part with, or does anyone know of anywhere I might be able to find a power supply unit from that would enable me to use my HiFi? It works on battery power and my friend has an adapter, that allows mains usage, but it means it will only play music to the same level as with batteries. Pleeeeeaassee could someone help me with any information? Thanks very much

Thanks!

Power supply cable melting before my eyes

I finally joined the famed club of the dead power supply owners.
I've had several issues lately with my macbook (while never had any although owner of the very first release of it), mainly with freezing windows, slow reaction time etc.
running Activity Viewer for the past couple days, I could spot mdmimport (Spotlight index daemon) acting quite berserk.
taking up to 97% of my CPU (today it even said it took 128%???).
anyway, I thought it was a fragmented hard drive, giving a hard time to index content, but the weird thing is that I regularly use diskwarrior to adjust the content disposition.
a very weird behavior was that the laptop seemed to start hogging the CPU only on-idle (doesn't that sound a bit odd?).
while the screen was black (after the screensaver timed out) the CPU fan was going berserk, and the power supply was sure close to melting point.
I was saying I kept the Spotlight daemon under control, and noticed that it kept taking all the CPU time.
the curious bit: what the **** are you indexing if maybe only 5 files have changed since yesterday and maybe couple dozens email?
today we got to the boiling point:
I work at some friends' office, go back home, use my laptop on battery.
the battery reaches 3% and I plug the power supply in.
no magsafe light going on, smell, the cable melting before my eyes.
luckily I had some friends with a spare power supply, but had to get to the root of it.
I decided to turn off indexing. ran
%sudo mdutil -i off /
the indexing of the main drive stops.
I've been using my tiger for a few hours already with no visible sign of fatigue, delays, cpu stress.
the cpu fan runs regularly but quite (consider it's a hot weather and my home is at 27ºC).
oh, if you're any curious, do you want to know when all this started?
mh... let me thing...
with one of the most recent Security Updates.
I don't remember which one, but it's not been longer than 10 days. probably a week.
anyone seeing any light in this?

I am convinced that the melting of the magsafe adapter in 99% of the cases is caused by improperly removing your power cord to many times. Don't pull!

Wind 6667BB-004US, blinking power supply light, no power?

So, I bought a Windbox Barebones Nettop this week. I came home from work today, and tried to turn the machine on; no luck. Nothing happens. If I hold in the power button for awhile... still nothing. Unplug the power cord, plug it back in, no change. Unplug everything besides the power cord, unplug the power cord, plug only the power cord back in, still no change.
Box is effectively dead.
The light on the external power supply flashes about twice a second. If I unplug the power supply from the machine, the light on the power supply is a steady green.
Dead power supply? Any ideas? Help, anyone?

Quote from: Stu on 09-December-09, 03:06:05
Take it back to the shop and ask them to exchange it.
Was hoping it was something I was doing wrong, or some reset button I didn't know about, or anything; mailing it back tomorrow, should have a replacement in a week or two.
(Thanks! Just wanted to make a last check that I didn't overlook something obvious.)

HELP! W500 dead. Ran system update, restarted itself, makes 3 loud beeps and thats it!

I just changed my hard drive, stuck in a windows 7 cd, installed it successfully. Installed chrome, dropbox and system update. Ran Lenovo system update, and at some point the computer restarted itself, made three loud beeps (long followed by two short) and thats it.
The bluetooth light is on, as is the power on, battery, and charger lights. Screen is dead.
What happened? What are those three beeps? What do i do?
Solved!
Go to Solution.

Turns out my new hard drive is loose. Have to do something to make sure it doesn't move around.
That was a scary moment.

Can't get a picture, only loud beep when I power on my desk top. Ois 10.6

When I power on my desk top, i hear the start up sound but only get a black screen and loud beep. ois 10.6

Please carefully read Mac computers: About startup tones
