My presario will not power up

pc will not power up the batter is good

Model number? Lots of Presarios out there since the late '90s. Try a hard reset. Pull the battery and detach the AC adapter. Hold down the power button 30 seconds then wait another 30 seconds then plug in the AC adapter and see if it comes on. Its a longshot but it is easy to do.

My laptop compaq presario will not connect to the Internet anymore after buying airport extreme. Why? It detects the network, accepts my password, but will not connect to Internet. I tried to repair connection, tried to reboot modem several times, I even updated my computer. Nothing. All it says is that it does not detect modem. Why?

Welcome to the support community group.
First, are you sure that your AirPort Extreme has been configured correctly and is properly connected to your modem?
Begin by telling us how you have things connected and if the Airport Extreme is replacing a previously owned router or is this an entirely new installation?
First be sure that your modem is working and properly connects you to the internet using an ethernet cable directly connected to your laptop. Once you're sure that's working, reset the AirPort to factory defaults by disconnecting it from power and pressing and holding in the small reset button on the back for 15 - 20 seconds while you reconnect it to power. Then turn everything off for 5 minutes. Connect the Airport to your modem with and ethernet cable to the Airport WAN port on the back (check the user guide to make sure you connect the cable to the correct port) then connect a second ethernet cable between the laptop and one of the LAN ports on the AirPort Extreme.
Then power up the modem first, wait 5 minutes and then power up the Airport, wait 5 minutes and finally power up your laptop.
Then run the airport configuration utility from your laptop. Since you're not using an Apple computer, be sure that all of your firewall, and virus blocking and checking software is disabled before you run the airport configuration utility. Once you run the utility, it should detect your AirPort and allow you to use the configuration wizard to set things up.
Check back if you're still having problems.

Thinkpad will not power up

Hi,
I have a Thinkpad A31 2652-C4U
The unit will not power up. The light that indicates the unit is receiving charge doesn't even come on, and hasn't ever since I came into possesion of the unit.
I know the power supply works, I tested it with a volt meter, and besides, it's also randomly compatible with an old Compaq Presario I have lying around, and it powers that unit up quite well. I've also checked the power input on the unit itself, and it's not loose. Doesn't matter if I leave the battery in the unit or take it out either
Since I received the unit for free, I'm willing to invest a small amount of money into it, just to see if I can fix it. But none of my typical diagnostics are applocable here, because the unit doesn't power up. So I was wondering if there were any suggestions as to what I might try next.
Oh. The unit has no hard drive either. The hard drive caddy is gone too. The unit does have a stick of ram, but I don't have any other computers lying around that are compatible, so I can't test it. Either way, those issues should effect the lack of power getting to the unit.
Anyway, any help you guys can offer me is greatly appreciated. I'd like to see what I can do with this thing.
Thanks.

OK...let's try this:
A30 board could be fitted into an A31 shell with some playing around, but these support only P3M CPUs while A31 are equipped with P4M CPUs. RAM is PC133 vs. DDR 266 on A31/p.
Everything else...keyboards, LCDs, batteries are interchangeable.
The board itself must be from an A31 and not A30/p or A31p if you're looking to get the machine running the way it's supposed to be...
Everything you need to know in the respect of part numbers, removal procedures etc. can be found in the HMM:

Good luck.

My Powerbook will not power up, but I can hear the fan running...

Please help!! My Powerbook will not power up, but I can hear the fan running when I press the power button to attempt to power it up. I just received a new power adapter because it wasn't working properly and it was doing this before and then it worked for a week and now it will not power up at all. It just starts the fan but nothing else turns on. When I plug the adapter, with the battery still connected, it will look as if it is charging but then the light on the plug turns from green to orange then off and doesn't power up at all. If I take the battery out and plug in the adapter, the light stays on but it does not power up except for the fan noise. Does anyone have any suggestions? I also followed the two articles listed online in regards to resetting the power setting and the command + alt + P + R as well. Nothing works. Thanks in advance.....

Same here. If I start up with the power adapter attached, it starts up fine. If I try to start up from battery only, the fan comes on, the sleep light comes on but nothing else happens. I tried letting it sit that way for about 15 minutes and nothing changed. I tried attaching the power cord while in this mode and nothing changed. I tried the PMU reset a couple of times but nothing helps.
This computer is just over 1 year old and I have not had any problems with the power cord (3rd party), the battery, or any problem like this before. It started after a proper shutdown last night and attempt to start without the power cord this afternoon.
Any answers to this yet? I think I'll call on this and report any success to this discussion.

Need Help HP DM3 (DM3-1130us) Laptop will not power on. No power at all except for light on a/c jack

Hello, I need some help.
I have a HP DM3-1130us Laptop that will not power on at all.
the only thing that happens when I plug it in is the power jack lights up.
When the power button is used absolutely nothing happens.
No power, no fans, no leds, no on/off cycles, no beebs, absolutely nothing
just the light by the power jack that says the cord is plugged in.
The laptop has Windows 7, 320gb hdd, 4gb ram.
I have tried new power adapter and still nothing.
I have taken the battery out and tried and nothing.
I've tried the option where you take the battery out and hold the power and nothing.
I have tried with different hard drive and no hard drive and nothing.
I have tried reseating the ram and tried new ram modules still nothing.
So I am kind of stumped on what to do, the laptop will just not turn on.
Its not under warranty anymore so cant send it off.
It has not been exposed to any elements(extreme heat or water).
and its never been dropped or anthing.
Im kind of wondering maybe the power button board its self is bad?
If feels fine, its not loose or anything but could it
have just stopped working? for those who are not familiar with this model.
the power button is on the side and is a kind of drag and release button.
Its also on the same board with the Wifi button and 2 Usb ports.
But Im wondering before I buy a new one if this is what it could be.
Or could the motherboard its self be bad?
But even if the motherboard is bad would it still power up
just not post?
Also does anyone know of any other way to try to power this laptop up
without using the slide button. I mean kind of like off a Dv6000 you can power the laptop on by using the Quicklaunch buttons on top but this laptop does not have those.
If anyone can provide any information I would appreciate it.
Thank you.

Hey Tyler,
Unfortunately it is difficult to troubleshoot this type of issue. The majority of the time when the computer wont power on with the same symptoms you described, the power supply board is faulty. Most of the time if the motherboard is bad it should at least turn on or so some signs of life. Like I said, this is most of the time. Sometimes it could do exactly what your experiencing. I would suspect the power supply board has failed since you are not receiving any sort of lights, sounds, etc.
You could check the motherboard for swollen capacitors or loose solder joints but sometimes you wont be able to find anything.
I hope this helps answers your questions,
Sean

My iPhone 5s will not power on and I need my serial number for support.

I am attempting to get help through Apple Support- Chat, but I need my serial number. It is not showing up in iTunes under the device preferences. Any other ways to retrieve the serial number through iCloud?
If anyone has any idea of what is going on with my phone, I would love some assistance. I live 45 minutes from the nearest Apple Store. Here's the situation:
About 2 weeks ago, my phone started shutting itself off and restarting randomly.
About a week and a half ago, I would randomly get a blue screen and then the phone would restart multiple times.
About a week ago I turned off Touch ID in an effort to resolve the issue, after reading some fixes from this community. That seemed to help. I do have the animation turned off, so I had read that there may be an issue between the Touch ID and animation reduction. If that had not helped, I was going to turn the animation back on.
Last night my phone seemed fine. I did hear it restart in the middle of the night once, but this morning it will not power on at all.
I tried connecting it to my computer through iTunes, but iTunes does not see it and I cannot access the device information from it.
My phone is less than a month old, and for the first two weeks it worked great. I am taking it into the AT&T Store today where it was purchased, but I don't really have high hopes for a resolution.
Any help is much appreciated!

Sorry AT&T store won't be much help.
I suggest you make an appointment with the Genius bar and then go to the Apple store.

Macbook Pro will not power on without battery installed

Hi there,
I have a Macbook Pro A1226 that fails to power on without a battery installed.
i.e. will not run off AC power on its own. I have tried 2 other power adapters, no change. All 3 adapters are outputting the correct voltage without fluctuations.
But, if I am in OSX with a battery plugged in, shutdown the laptop, remove the battery while AC is still plugged in, it will power back on without any issues. But as soon as I remove the battery, it will not power back on using just AC.
Is this an I/O board issue, or a mainboard?
I have power drained the unit and reset the parameter ram.
Thanks

Any update on this? This is the same thing that's going on with my laptop right now. I was at the Genius Bar and they said they can send it in for repair. Takes 7-9 days and costs a minimum of $310. At the time I was there, my computer wouldn't start up at all, because the battery had drained to less than 20%. It didn't even start with just the power cord (no battery in). The "genius" finally got it to work by doing a PRAM and SMC reset. Got home and was able to recharge my battery to 100%. Used my computer for 2 days before I dared to take it off the power supply. Lo and behold, as soon as I take it off the power cord, then re-connect it, it shows "Not Charging". I tried to do SMC again, but no luck. Keeps saying "not charging". Even tried with a brand new battery. Do I have to get the I/O board thingy replaced?

Ipod touch generation 5 will not power on

My ipod touch generation 5 will not power on though it was showing to b e fully charged. I have been pressing and holding the on button on the top which usually cause a the screen to light up. Is there some way to get it to work?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

HP Pavilion dv6000 will not power up.

I have had an HP Pavillion dv6000 for a few years, and suddenly, it will not power up at all. I can not determine that anything at all happens when I press the power button. What's weird is that when I connect the power, the AC LED (the one with the lightning bolt above it) lights, and stays lit for 30 seconds, and then turns off. During that time, and thereafter, the power light will not come on at all, and the computer will not power up. I have tried removing the battery and power cord and holding the power button for 45 seconds, multiple times, but nothing seems to work. I hope you can offer some advice on things to try.
Thanks,
Zach
This question was solved.
View Solution.

Well, I've had the problem for a while and was just looking around to see if anyone has had any success stories.
I will tell you how I get mine up and running, but first some background. I was gifted this computer DOA and asked to retrieve data which I was able to do but in monkeying around, I discovered a "fix".
You see, I live in an area where we occassionally lose power for a day or two or three so the weakened battery never outlasts the outage. That's when the unit becomes unstartable.
Now the fix:
It is a variation of all the other suggestions about undoing the power cord and disconnecting the battery but here's the twist: After removing the battery and power cord, wrap your laptop in one then another plastic shopping bag and place it in the freezer for about an hour or two. Now, when you take out your shivering laptop, plug in the power cord and fire her up. It has nearly always started for me after this trial by cold but once or twice it needed more chillin'. Once it is started, insert the battery. I've never had any issues with this sequence.
You will have a lot of condensate on the screen but gently wipe it up with an absorbent cloth and let the rest of air dry as you let it run.
As long as I leave the computer plugged in and not reliant on the battery, it has never died on me.
Hope this helps!

External hard drive will not power on

I have a PH3200U-1E3S and it will not power up, every other push of the power button the light flashes once. I dont know what to do, any suggestions? The unit is not very old and it has all off our pictures on it.
please help,
Thanks Tony

If it is out of warranty, you might try opening it up and looking for a fuse inside. If you find one and it is blown, you should easily be able to find a replacement.

2nd Gen Time Capsule - will not power up - just stopped working all of a sudden - I have tried other power outlets - I have tried pressing the reset button - no light

The power supply is shot. But that it lasted even this long is the wonder.. not that it died.
The TC runs too hot..
Look on ebay for "Time Capsule power supply"
You can get a replacement and fix it although the economics are not so good.. it is probably time for a new TC.
If you can DIY it is really only a few dollars worth of capacitors that go bad.
