Hp Pavilion elite will not boot

My pavilion wont boot after an electrical storm. I think there's something wrong with the power button. There is a green light on the back that isn't flashing, but staying solid green. Nothing's happening when I press the power button, no fan, no response from the monitor.

It could be the power supply, shorted device of any kind attached (bad printer, flash drive, keyboard, mouse, network connection), memory problem, video card fan not spinning and the video card could have overheated, bad capacitors (rounded or leaking a brown or dark substance). The first thing you should do is make sure it is not under warrantee. If it is, contact HP. If it isn't, remove the cover and inspect the board for bad capacitors, fans not turning, disconnect all non essential items like the hard drive, DVD, floppy if you have one, all external devices (yes the monitor) and turn on the computer. Does it appear to stay on? If yes, shut it down by holding in the power button for 5 or more seconds or flipping the power switch on the power supply or pulling the plug. Connect the monitor and then one item at a time leaving the hard drive with your important data as the last item. If it didn't stay on. Try to use only one piece of memory and try each memory slot, try the next piece etc. If that doesn't work, the best guess is the power supply (if you have an ohm meter - test the power supply first).

My HP Pavilion zv6000 will not boot/recovery

My HP Pavilion zv6000 will not boot/recovery need help

Disconnect the AC Adapter and Battery from the unit. Hold the Power button down for about 15 seconds. Then without the battery being connected, plug in only the AC Adapter on the unit and check if this powers on the unit. You can also try to reseat the RAM on the unit. You can find the removal procedures on the Service and Maintance guide on www.hp.com for your model notebook. In case the notebook does not work after these steps, it could possibly be a hardware issue on the unit.

HP Pavilion a1467c will not boot

Every time I try to start my Pavilion a1467c desktop the start button lights up, but the HDD light comes on yellow for about 30 seconds and then goes out. The display comes on with a blue screen with vertical white lines. The OS is Windows XP. I suspect the power supply, but the fan on the power supplie runs. I am looking for advise from someone with more experience.

OK. Let me answer my own question. Other than the blue screen with vertical white lines, the PC was acting like I have seen other PCs act on prior occasions. Upon starting up the computer, all goes well except it will not boot up and the HDD activity light goes out. Most of the time was related to a bad memory card. I opened up the case on the desktop, removed the three memory cards, cleaned the contacts on the memory cards, and reseated them in the slots. I then closed the case, plugged the power cord back in, pushed the start button, and the PC booted up like normal. I have rebooted it several times while updating drivers. It has been running for the past two days without a glitch. Simple fix.

Hp pavilion laptop will not boot up.

I get this error The file header checksum does not match the computed checksum. I'm not able to do anything with it after this screen, it will not boot to safe. What can I do?
I've removed the battery, which is dead anyway; laptop is plugged in. Have tried different power source and that doesn't help.
There is no blinking cursor, etc. I have tried F2 & ran that memory & hard disk diagnosis & nothing seems to be amiss. On the error log I really didn't see any errors.
I don't have recovery disc either but laptop won't boot to cd rom drive so even if I had recovery disc am not sure that would work.
Help please I'm at a loss now of what to do. Thanks.

Does F11 at power on work to boot into Recovery?

One day, the computer booted up so slow it never eventually came up. Then upon reboot, it never got past the beginning screen (black with blue circle rotating). We have no ability to get onto the computer anymore.

When I start my Pavilion dv6, the fan starts, the on key light on, light on f12 key and on caps lock key.
Screen remains blank.
Have tried taking out battery, and unplugging. Wait and power again. Same thing keeps happening.
HELP please.

Hi Thesaloniki,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP Pavilion dv6 Notebook and getting a blank or black screen on startup. Try performing a hard reset. When performing a hard reset please note remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices. If that does not help try to turn on the computer you start to press F2 repeatedly till the menu opens. You can do a diagnostic test.
I would be happy to assist if needed as there are many models of Pavilion dv6's could you respond with the mode.. How Do I Find My Model Number or Product Number?
Please respond with which Operating System you are running:
Which Windows Operating System am I running?
Please let me know.
Thanks.

HP Pavilion a6763w will not boot up..

I have an HP Pavilion a6763w that suddenly wont boot up.
I was using it just fine last night, went to use it this morning the screen was black and the CPU fan was running full blast, I could not get it to turn off, the only way to shut it down is to pull the PSU plug.
when you press the power button the fans come on very loud and full blast but never slow down, there are no beeps, you can hear the HDD spinning and the HDD indicator light stays lit solid, however there is no display on the monitor.
I have tried different monitors, i have tried removing and replacing the RAM, I have tried a new PSU, i even found a post about unplugging the multimedia reader but to no avail.
I wonder if anyone can tell me what they think the issue is so that i can replace that specific part of this computer as it was not cheap!
i am linking a video i posted to Youtube so that you can see the symptoms as i described them
video

Let's try a little diagnostic work: Unplug the power connectors from drives and everything else you can, and see if you can get as far as the POST. If that works, then there must be something going on with one of the peripherals. If not, then the signs point to the motherboard itself.
You could always try resetting the BIOS, but that's a slim hope.

HP Pavilion dv9207us will not boot up

This laptop is less than 2 years old. One day, it locked up. Upon hard reboot, nothing showed on LCD. Connected an external monitor, showed bios coming up, etc. However, the graphics were all messed up. On the external monitor there are large green blocks, which obstruct the viewing area. LCD panel of laptop does not show anything, however, it is powered, and I can see backlight.
With the help of external monitor, I booted up in safemode. However, nothing doing as expected. When tried to boot up in normal mode, I was informed to use recovery disc. I tried to use a clean copy of the DVD that I had made, but did not work. Error: Restore7.exe application error. Called HP who shipped me a recovery DVD - same results.
I ran diagnostics on RAM and HD. They were both 100% pass. I took HD out and plugged into an adapter - could back up data files, ran Norton Enterprise Antivirus, etc. Everything was fine. I was able to back up data and did not find viruses or trojans. Finally, I put the HD from HP laptop into another laptop, and I was able to bring up the Vista Home Premium and operate it as I was able to operate it before.
Finally, I've researched on the net about this issue. I've narrowed it down to NVIDIA 7600 card that is populated on the motherboard. I've noticed that this was an issue on AMD processors of the similar dv9000 series. My motherboard is Inteal Centrino Core Duo G73M Chipset with 256 MB Graphic Video RAM memory.
I've called HP and they inist that the problem has been isolated to AMD based motherboards. I do not believe that! I have the same symptoms in the same timeframe that others had experienced.
What are my recourses?

Look at Reflowing which has become somewhat of an art. There are hundreds of videos on You Tube showing different procedures...if you know someone good at this sort of thing.

HP Pavilion s3500t will not boot

HP Pavilion s3500 failed to start. The monitor is working but show no signal. Switched RAM and the fan just runs at high speed. What else can I do to try to get the sistem to start?

So did it prove to be a failed power supply or was it a motherboard issue? It would be helpful if you would post, if you see this.
Also, why the change in RAM - is that supposed to be a solution to a motherboard issue?
Today my s3500t failed to provide any response at all to power, and the suggestion from support was also to unplug the power supply from the motherboard and try again, to see if it was not a power supply failure but a motherboard issue.
However the connection of the 24 cables to the motherboard from the power supply was far too tight to try and remove without risk to the motherboard, so we just went with a power supply replacement, which apparently it is 98% of the time.
The manual had no instructions to the support guy as to whether there was a way of removing the connector innvolving a release catch of some kind, so we assumed there wasn't. Possibly a pair of pliers would have done the trick, at some risk to the motherboard.

Maybe... it depends on exactly why the drive has failed and how far gone it is.
You may be able to find an adapter that plugs into the sata hard drive and into a USB port on your laptop. Maybe TigerDirect.com or Ebay? Once you have the new hard drive installed and the operating system back in place, you can plug it in and try to access the drive through Windows Explorer.
If this doesn't work, and depending on how badly you need the files, you can download something like Hiren's Boot CD which has a number of tools in it that may allow you to access the data, but that may require a significant amount time and effort to understand and use the tools properly.

HP Pavilion Elite m9258 will not boot up. Won't recognise USB ports -mouse keys etc

HP Pavilion Elite M9258
70 percent of the time will not boot up.
Computet light is on. DVD drive will open and shut. Fans sound slightly quieter when this happens.
The monitor comes on but the light goes to orange. When I press any of the monitor buttons, it flashes a message for a few seconds telling me it is in sleep mode and invites me to move the mouse or press a key to continue
The problem is that the USB ports are not recognised by the computer at this point. The infra red mouse light flashes briefly when the computer is switched on then goes and remains off. The keyboard is also unresponsive.
The sole fix that I can find is to repeatedly turn the computer off and on again. After 70 -100 attempts ( over 4 to 6 hours) it suddenly boots up normally. The problem began a year ago and is increasing in duration and severity.

I am having the same problem as Avro500! My computer is the hp pavillon desktop model a6863w. The computer freezes then the keyboard and mouse will not respond and the only thing I can do is shut it down and even then I have to hold the pwer button about 10 sec before it shuts off! I have unplugged all external devices like you told avro500 to do and I did finally get it started but the computer still freezes and it is doing it more often as time goes by! I even paid HP support the $100 dollars (or around that amount) to fix it but it keep happening even after they worked on it but it was after the 7 days or what ever their policy is! They downloaded some security suites and ran their scans! They left Advanced system care, ccleaner and superantispyware on my computer and I was just wondering if they could be conflicting with my paid norton internet security? I have become very flustrated because first off I paid a lot of money for this computer and it's not even 2 years old yet and I also have paid HP a lot of money to fix it and all the guy from India could say to me was "I have been working on this computer and it hasn't froze up so the problem must be fixed!" Well it's not!! and I don't know enough to fix it myself so thats why I paid you a hundred dollars to do it for me! haha thanks for any help!
