Dv7-1273cl won't power-on

Warranty still good until 2011-03-31, bought at Costco. I press the power button and the lights come on for about 1-2 seconds and then it dies. Tried taking the battery out and putting back in, no luck. Won't power-on at all w/o the battery in (no lights, no nothing.)

to those who have NOT solved this issue yet, we know you are out of warranty, so try this. i'm not sure how long this will last, but this should help. the computer's power circuit has a defect that HP didn't mention. the dv7 2nd Gen. has a problem where the primary power circuit stops responding to the correct voltage. here's a quick fix.
WARNING!
this mod puts your computer over-voltage by a few volts and i am NOT responsible for your loss if you do this mod incorrectly!
NOTE: you cannot charge your battery with the computer on with this mod with the stock charger. the charger that comes with the computer is 3.4 amps (65 watts, and you need 4.2 amps or 90 watts)
IF YOU FOLLOW THIS TO THE "T", YOU WILL GET THE COMPUTER TO POWER ON, BUT ITS A MOD AND ITS UNTESTED IN THE LONG TERM...

* you point the finger at me for messing up your device, I will laugh at you.
short the center pin to the outside white wire using solder to bridge the connection between the +14.4V connection coming from the charger. i personally used 26AWG wire and carefully wrapped it around the 2 pins and then soldered them. thin solder braid also works very well. i must reiterate that you cannot use ANY other pins than the second to the left. review this video on youtube for reference. this is what helped me to get it running.

try to use the wire with the solder as its a better connection and is more solid. do not use rosin core solder, only tin-lead solder. you may use fluxall tin-lead solder to make it easy, but its a tad messy at first when heated. flux kind of spits at you a little bit. haha.

Pavilion dv7 3079wm won't power up with/without battery or ac cord

Tried to power up with a.c. cord or battery. Leads flash once attempts to start, then goes out.

I hope you folks won't mind my piggy-backing on this thread. I have a very similar problem with a dv7 (belongs to my grandmother).
When I plug in the AC adapter, the small LED next to the socket usually does not light up, but will flash briefly when the power cable is removed. The AC adapter is fine, because I've used it to charge and run my dv5 with no problems. If I unplug and then plug the AC adapter into the socket repeatedly, eventually at some random point the LED will stay on.
However...
The battery light is slowly flashing. It flashes anytime the AC adapter is plugged in (whether or not the LED next to the jack lights up).
The computer won't power up. It tries to for a second or two, then shuts down... as if the battery was critically low.
Now the thing that puzzles me -- The computer won't start up on AC power without the battery installed. I can do this on my dv5 with no problem. It does not require the battery to be installed. I figured if the battery is completely dead in the dv7, that it may be confusing the system and not allow it to start at all. But, trying to start up the dv7 without a battery does absolutely nothing at all.
I'm hoping that the dv7 is designed to always work with a battery and that all I need to do is just install a new one. Does that seem sensible? I just don't want to buy one (they cost a whopping $140 from HP!) only to find that the computer is suffering from a more serious problem.

Dv7 3085dx won't power on after adding 2nd hard drive

I'm attempting to add a 2nd drive to my laptop (dv7 3085dx). The drive is a Seagate Momentus 750GB drive (ST9750420AS). I purchased the drive caddy and connector from Newmodeus. The laptop will not power on after the drive is installed in the 2nd bay. Everything is fine if the drive is disconneted.
Any ideas?

Are you absolutely sure you got the right caddy and cable from newmodeus? They sell several different ones for the dv7 series and they look similar but are not compatible with each other. I understand the reluctance to try hot-plugging it.

Dv7-1157cl won't power

I have a dv7-1157cl that when you plug it in the light next to the ac port lights up. However the charging battery light does not light up and when you try to turn it on it does not power. I have tried turning it on with just the battery in and unplugged and with the battery out and it being plugged in with no luck. Any suggestion? Or does it sound like the motherboard needs to be replaced.

HP DV7-3085dx won't power up, seems the battery and charging is ok.. possible mother board problem?

Hi I recently received an HP DV7-3085dx from a friend of mine since he hadn't been using it for a while.
So, when I tried to turn it on for the first time, the power button wouldn't work, or the lap top itself wouldn't power on.
When I plug in the charger, AC adapter light turns on, and when I connect the battery, both the battery light and the AC light turns on fine.
However, there's no fan, or any light flashing when I press the power button as if it's dead.
I've searched and tried:
1. hard reset - pressing on the power button for a minute without any attachement and so on
2. reseating ram and CMOS battery
3. cleaning heatsink and re-applying thermal compound.
4. tried turning on the laptop without hard drive.
However, none of those would solve the problem.
Could it be the faulty motherboard, fan or heatsink?
Or, does battery light on means the motherboard is safe, at least?
By the way, it seems like the battery charges just fine as after a while on an AC, the battery light turns off(signaling that it's fully charged)

Hello coolhair50, welcome to the HP Forums.
I see that you've acquired your Notebook from a friend, that you're trying to get it to turn on and start up. That only the batter and charger appear to be working as the Notebook will not turn on. I will try to assist you with this.
You're on the correct path, the issue does appear to be hardware related from what you've attempted so far. The battery and charger appear to be fine.
What I would suggest starting with is this document: Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot. It will guide you through testing the memory and hard drive. If all of that tests ok, then you're most likely looking at a motherboard issue.
You have a few options at that point. The first would be callling support to see what they could offer. HP Technical Support, North America 1-800-474-6836. For all other regions click here.
The second would depend on your own personal knowledge of Notebooks, but you could use the Maintenance and Service guide to look up possible compatible parts and how to replace them.
Please let me know how everything goes for you.
Thank you for posting on the HP Forums.
I worked on behalf of HP.

what to do

Have you tried starting it without battery?
Have you reseated memory.
Try removing 1 stick of memory and see if it will start. If no joy,switch the memory sticks and try the other one.

Installed the update tonight and now my phone (Lumia 928) won't power up. I've tried a soft reset, but the screen goes from the Nokia logo to a red Verizon screen to a black screen. What's wrong and how do I fix it? Help!

Installed the update tonight and now my phone (Lumia 928) won't power up. I've tried a soft reset, but the screen goes from the Nokia logo to a red Verizon screen to a black screen. Tried it 10 times with the same result. What's wrong and how do I fix it? Help!

Oh no Mr.Ected!
I can see if we can get your phone back on! I understand how important it is to have a phone. Have you tried this to see if we can get it back on? http://vz.to/1DZhteH . If it is still goes to a red Verizon screen and then to black we might need to do a master reset. While the phone is off try this:http://vz.to/1DZhXkU Be mindful this is the last resort because it will erase everything on the phone. If you have done back up assistant in the past you will be able to get you contacts back. Please let me know if you need any more help.

Please Help! My iPhone 4 won't power on!

iPhone 4, out of warranty coverage, won't power on.
    1.    It has about 60% battery before it dead, but suddenly it became black screen and not responsive (like powered off).
    2.    Whatever I did, like "holding the power button and home button together for 10-25 sec and then pressing the power button again" etc. it just won't power on, no Apple logo!
    3.    But I can seen the "emergancy call" screen when I plugged it with my laptop and it just told me "No Service" at the upper left corner (status bar of iPhone 4).
    4.    iTunes can see it, but only when it was in Recovery mode or DFU mode.
    5.    I also tried to restore it to factory settings in iTunes, but it always gives me an error with various error codes, like 2001, 2006, etc. I also tried restore it under Windows or Mac, but was out of luck too!
    6.    Finally I bought a iPhone 4 battery replacement and replaced the old one with the new one, but nothing changed as if it wasn't replaced its original battery.
    7.    It keeps rebooting at every 10 min or so when It was plugged into my laptop without any operations (pressing any buttons).
    8.    It can be "powered on" only when it was plugged into a computer. It will IMMEDIATELY be in "dead mode" as long as I disconnect it from the computer (like taking out a battery from an iPhone that is powered on)!
    9.    Everything worked fine before it dead, I don't know what happened to it! I am so frustrated!
Please help! Thank you so much!

USB Problem, possibly bad Cable.
I misread your original post "It keeps rebooting at every 10 min or so when It was plugged into my laptop".
I thought you had a boot loop problem, but you say "rebooting when plugged into laptop" this is not the typical boot loop problem, because you had the iPhone connected to laptop.
Connected by what, obvioulsy a USB Cable, Error 2006, is most often due to faulty USB Cable.
Clean that Dock Port Very Well especially with Isopropyll Alcohol, get a good USB Cable, try a different USB port on computer, or try a different computer.

My kid just got an iPod 5th gen (today from Santa) and it won't power up or charge. The only response is when I connect the USB and press the power button or front button the Battery appears with red line and lightning symbol. No other response at all.

Sorry about the long title.....its my first post.
My kid just got a brand new iPod 5th generation (today from Santa) and it won't power up or charge. The only response is when I connect the USB and press the power button or front button the Battery appears with red line on left and lightning symbol below. There is no other response at all no matter what I do, including holding both buttons down for extended period. My other kid got one and it works perfectly.....I have interchanged usb cables ports etc. but still no response....I would really appreciate any help.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Make an appointment at the Genius Bar of an Apple store since you have a hardware problem with the iPod. This is because as you said the same cable works with another iPod.

Zen Vision:M 30GB won't power down; any ide

I've had a 30GB Zen Vision M for a couple of months now! Awesome player, went through the usual round of recognition problems, but it's been working fine of late. My problem is, it won't power down now. When I try to power down, the unit says it's powering down, the dispaly goes black except for the battery icon. And it stops there. The blue backlight on the menu buttons stays on, the battery icon stays on, and eventually it turns off after 5 minutes because of being idle. Not a terrible problem I know, but a real niusance. I am running the most current firmware (have been for a while). I've tried resetting and clean-up. No change. I'm afraid of trying to reinstall the firmware, in case I have the same problem that many others are having, and go from a good player with a power issue, to a player that does nothing. I can't see it being the power switch itself, since it powers up fine, and tries to power down. Any ideas or advice would be greatly appreciated. birder

Can I recover data if my phone won't power up?

So my iphone 6 accidentally went through the wash on Monday night. I immeadately tried to dry it out in a pyrex dish of rice with a heating pad covering the dish. It was in rice for 36 hours and still won't power back up. I knew it was a long shot, but it previously worked for a iphone 3s and 4g. Any suggestions on possibly recovering this hardware or how to recover the data (no icloud storage) w/o the abilty to power the device on?

Not really - that data is gone unless the phone somehow wakes up
The conventional wisdom for the rice is 5-7 days though

IBook G3 800mhz powers & starts up, after a shutdown it won't power up

One day my iBook G3 800mhz was working fine. I shut it down and later went to turn it on and it wouldn't do anything... no startup chime, no fans, no lights, nothing. I tried resetting PRAM, PMU, and many other things which didn't work at all.
I had a local computer store check it out and they told me the Motherboard was fried. I pretty much wrote the iBook off as DEAD. I took the battery out and it sat that way for about a month.
Today, I put the battery back in and hit the power button, and IT POWERED UP & BOOTED! I couldn't believe it. I shut it down and hit the power button again... nothing, it was "dead" again. I took the battery out and let it sit that way for about 2 hours, put the battery back in, pushed the power button and it BOOTED JUST FINE. So, I shut it down, pushed the power button and it was "dead." I took the battery out again, let it sit for an hour. This time instead of installing the battery I just connected the power adapter, pressed the power button and it BOOTED. To determine if it was the battery, I left the power adapter plugged in, shut down the iBook and pressed the power button... NOTHING, "dead" again. So, it's not the battery, it's not the power cord.
When I do get it booted, I am able to do a succesful Restart by selecting it in the Finder. Also, whenever it does power up, I am able to reset the PRAM and it will start up. Whenever I do a Shutdown (either from the Finder or by pressing the power button) it won't power up unless I disconnect the battery and power adapter and let it sit for about an hour.
I've been through all the forums and many websites and have yet to find a fix for this problem.
Anyone have any ideas?

Hey Shim..,
Certified Apple Technician and he agreed that it is probably the transistor (what he called it) that is failing, since it's not holding Date & Time
OK but a transistor is a long way from a microprocessor. Uhh where did he get his...oh never mind.
I have read in some forums about the leaking super cap,
I'd be interested in those leads
but I haven't been able to find any photos or anything that shows where on the board this is located.
Just put one up here, it's from a 12" G4 1.2 GHz:
http://www.photolava.com/view/d5pr.html
They're pretty distinctive, so hard to miss.
Here's the blowed up one from the 500MHz 12" G3
http://www.photolava.com/view/d5pu.html
Now that's blowed up
Is this cap replaceable? Anyone know of any step-by-step guide that would show how to go about this, or know of any company that might do this sort of thing? If it's not too terribly expensive, I'd be willing to give it a try.
Well let's determine if it's bad first. Usually when these things fail it's pretty obvious.
I'd try blowing out all the chips we talked about first since I believe a tiny bit of smutz will cause a CMOS micro to crash.
It reminds me of when these early PMUs will crash and drag the battery down with it in a matter of days vs years.
One of the resets in those was to remove all power and let it sit just like you're doing here. This was called resetting the logic board and was SOP for a no startup situation.

I dropped my iphone 4s and now it won't power up, I dropped my iphone 4s and now it won't power up

I just dropped my phone onto asphalt from the car, about a 2.5 foot drop. The phone was wearing a case and no damage was done to the phone. the phone was off when I picked it up and will not power up. Any suggestions for how to fix this myself?

Apparently some damage to the iPhone did occur. Using a case doesn't guarantee zero damage when dropped depending on the case.
If the iPhone won't power on the normal way and the same with a reset, make an appointment at an Apple store if there is one nearby.

I have a macbook and when I power it on and then select myself as a user...It won't power up. It stays in the white screen with the apple logo. I am online currently under 'guest user'. Is there anything I can do from the keyboard to fix this??? Help!!!

Could you specify the model of MacBook and the OS X it's running, please? Some of the advice or references vary along with the system, so this could be helpful to formulate a reply. I've never used a Guest User selection, but do have more than one User.
If the computer does not have an optical drive, you may be able to boot it into a recovery disk mode or something; in an attempt to see what is wrong and maybe fix it.
Good luck & happy computing!

Computer Won't Power Up

After a BIOS update that went wrong, I received my mobo a few days ago from MSI. I re-assembled my computer 4 days ago, but started having random crashes. Today I decided to test the memory. When running memtest86 the pc just powered off unexpectedly. I switched it back on again, but after a few minutes it shut off again. This time for good.
I disconnected the power cable and plugged it back in. 4 red lights on the D-bracket flashed, the PSU, CPU, Northbridge and case fans moved slightly and then all went dead. I didn't hear any beeps or other sounds. This response lasted less than a second. Same thing happens if I turn off and on the PSU's power switch. The case power switch generates no response at all.
Here is what I've tried already:
- Cleared the CMOS - No changes
- Striped everything, leaving only the CPU, and then re-assembled one component at a time and powered on and off the PSU after re-assembling each component - No changes
- Unplugged the case's power switch cable and direct contacted the 2 pins with a screw driver (to check if the problem was with the case's power switch) - No changes
Any thoughts?

Exactly Bass, I hope that it wasn't a Windows flash...
That's exactly what it was. However, I got the pc running for 4 days after MSI solved the BIOS problem. After the power up problem I took the pc to the my local tech service and they said it won't power up because the board is dead. Everything else works OK when instaled on another board.
Blazer, I took the battery out and inserted it again but that didn't fix anything. I have no multimeter, so I couldn't test the battery. How long do these batteries last? My pc is 1 1/2 years old (running 24h a day, 7 days a week).
