Pavilion G7 laptop stuck in POST loop

Clients Pavilion G7, originally came with Win 7, but client upgraded to 8.1 about 2 months ago.
Power on, black screen with message: 'Press the escape key for startup menu' at bottom left. Cursor blinks in upper left corner 3 times, screen goes black and repeats.
I can get to the startup menu. All diagnostic tests have been run and passed. Boot device options show Internal HDD, then internal CD/ROM for boot order. I have entered BIOS and reset all defaults with no change. Only remaining option is F11 for System Recovery and that just sends it back into the loop. Changed boot order to internal CD/ROM first and inserted known good Win 8.1 install disc with no change in behavior.
What next? Please help.

Immediately after powering on tap the Esc key. From the menu tap F9 Boot options, then select the CD/DVD drive. Even with it set as first boot device in BIOS for some reason it requires these steps to boot from CD/DVD.

HP Pavilion G6 Laptop Stuck on 0%

Hello, I have recently encountered a major problem in charging my HP Pavilion G6 laptop. I had not been using my laptop for a week as I had been using it frequently beforehand. I charged it and when I booted it up it said it had 0% while it was still connected to the charger. I left to to charge for longer and even though it said it was charging, the laptop remained on 0% of power. It still works (Very slowly now), but if I remove the charger the laptop immediatly shuts down due to it displaying that I have 0% of charge. I assume the problem lies with the battery, but before I buy a new battery I'd just like to know if this problem can be explained and can it be solved with a more practical method? Thank you.

Hi there, glad you posted your question here before buying another battery. From what I've found, there are still a few steps you can try first
Please take a look through this whole guide, hopefully it'll help kickstart that battery and the connections back to life:

How do I get rid of the Microsoft Setup Assistant loop? I migrated my software/documents from another laptop so don't have the disk to reinstall. Please help! Can't open any Microsoft Office software, like Word, and stuck in a loop?

I migrated my software/documents from another laptop so don't have the disk to reinstall. Please help! Can't open any Microsoft Office software, like Word (for 2008), and stuck in a loop?
Whenever I select Word Microsoft Setup Assistant appears, asks for feedback, then after selecting okay (both on saying yes or no to feedback) goes on to a registration page. When I click on this it says I've already registered so I just click okay, and then move on to a update page. After this, if I click on Word, the process repeats itself.
As I said, I don't have the disk to reinstall, and can't find the Office Settings to delete as many pages have suggested I should try. Safe Boot restarting also hasn't worked... Really stuck and need Word very soon for work.
If you can help, that would be great, and feel free to ask any questions about the situation as I'm not an expert here.
Cheers,
Jack

First, export your contact from iCloud.com and save them on your computer in a safe spot some where (like you desktop). Use this to help you do this: http://support.apple.com/kb/PH3606
Next, on both of your devices, go to Settings > iCloud and turn on contacts and select Merge. Then turn off contacts and select 'Delete form my [device]' when prompted.
Now go back to iCloud.com and select a contact (yes they will all be messed up again) and select Command+A on a Mac or Control+A on a PC to select all of the contacts. Tap the delete key on your keyboard (or right click /control click a contact and select delete).
You iPhone, iPad and iCloud.com should not be empty for contacts.
Go back to Settings > iCloud on both devices and turn on contacts again (you should not see merge this time).
Next, go back to iCloud.com and import your contacts (those exported .vcards). You can either drag and drop them into the empty contacts list in your web browser, or you can use the gear icon to import.
You cleaned up contacts should import correctly into iCloud.com and sync to both of your devices.
Good luck.

My laptop cd burner is stuck in a loop; can't eject cd

Sometimes when I burn a cd, the burner in my apple laptop gets stuck partway through the cd. I'm guessing it might be a flaw in the cd that is causing this. Not sure. The problem is I can't get the cd out or stop the import. The burner seems to be stuck in a loop. You can hear the sound of the burner trying over and over again to burn the trak. What do I do? Turn off the laptop and give up on burning that cd?

Found out the other day:
If you hold down the mouse button while the computer is starting up it will eject all removable media - including CDs whether or not they have been recognised.
So if you restart it's a sure fire way of getting the CD out so no need to panic about it getting stuck.
I can't help with making the thing work though - once you start burning a disk and it makes a mistake that disc is usually ruined, in my experience.

How to recover ALOM Main Flash (ReFlash EPROM) ? -- ALOM stuck in a loop

Hello,
I had an issue while flashing the ALOM Main Flash of a Sun Fire v210.
Now the ALOM boot is stuck in a loop trying to load the main ALOM image.
As a result the ALOM Main Flash is broken but I can still access the
ALOM Boot Menu. I can also boot Solaris with the Jumper on FP2 or FP3
but it does not recognize the SC anymore.
Is there a way to recover it from Solaris and/or using the
"f - Wait for flash download from host" from ALOM boot menu ?
ERROR ON ALOM Boot

Anybody knows if the source code of scadm tool is available somewhere ? (opensolaris etc. ?)
I don't have any additional advice to offer other than asking that you to try the flash-update all over again,
one more time, as if it were the beginning again.Yes but how because the SC is not discovered anymore by Solaris :
"rmclomv: WARNING: DP_GET_SDP_VERSION failed, ret=4"
"The SC hardware could not be initialized."
Can you try to flash the mainalomfw ? Your log contained only the flash of the alombootfw !
/usr/platform/`uname -i`/sbin/scadm download alommainfw
I guess jumper JP2 allows to recover from a failed flash by selecting the un-touched half the PROM.It does not work as the SC is not responding anymore to Solaris

It's a pitty that obtaining OBP/ALOM updates requires a service contract. I got a V210 recently.
Unfortunately both OBP and ALOM are the intial release 4.8.2 / 1.0.I agree but it's probably also because you need support in case it fails ;-)
Thanks for your answers!

IMac froze, rebooted but finder stuck in crash loop...

I have an iMac 2007 running Mavericks. Recently it has started occasionally freezing where my mouse still moves around the screen but everything on the desktop is completely frozen. After holding the on/off switch to reboot it usually comes back on and opens the folders/programs that were already in use and all is well.
However, today was different....it froze while I was using Safari....so I held the on/off switch as usual to reboot and the usual pop-ups appeared, asking me to re-open programs etc. However, since then I can't get finder to open...I have a constant flashing message saying "Last time you opened finder, it unexpectedly quit while re-opening windows. do you want to try to re-open windows again. - It gives 2 options 'don't reopen and re-open'....but the box is continually flashing very second as though it is stuck in a loop....doesn't matter what I try to press, it does the same thing over and over. It means I can access anything on my dock but cannot see my desktop files or any other files on the hard drive. I haven't done a time machine backup for a long time so wary of my next move. Ironically, I just bought a new drive for time machine and this happened before I got the chance to do the backup!!! Typical.
Other useful info may be that I think I only have around 3gb of free memory space on my hard drive right now.
I am on version 10.9.4 of Mavericks and there is a software update available.....should I try to do the software update to see if it irons this problem out or is there anyway I can backup my hard drive first or any other way of accessing my hard drive/desktop files before I do anything?
I have seen this problem related to Google Drive before but I don't use that...unless it is installed somewhere on my system without me knowing and still causing the problem?
Any help greatly appreciated....
Thanks

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the name of the crashed application or process. For example, if iTunes crashed, you would enter "iTunes" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste topost the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

Pavilion dv4405nr laptop hard drive and recovery

Hi,
My daughter's Pavilion dv4405nr laptop's HDD (Samsung MP0804H Spinpoint M Series 80GB) is dead. It doesn't boot, and BOIS HDD test gives error 7. I took the HDD out, and connected it to several PCs (home, work) using two HDD universal adapters (like a BYTECC, and a NewTech) I left it spinning for about 6 hours. The PC sees the mass storage device, but it never shows up in MyComputer with a letter assigned. By right-clicking the working HDD and checking its properties, it lists all HDDs and I can see the damaged one listed w/o a letter assigned. I click to load volume information but all displays zeroes. I downloaded a Seagate-Samung utility to test the drive, and got the same error I had gotten with the laptop's BIOS utility.
Can this HDD be recovered? Is there a utility that can recover it?
If the answer is no: I connected the HDD back into the laptop, and set the boot sequence to DVD drive. I inserted the "All-In-One Recovery DVDs" for this laptop, but they didn't boot. Aren't the recovery DVDs bootable?
Your help and suggestions will be greatly appreciated.
Sincerely,
Richard

It looks like this unit came with Windows XP. It really depends on when in XP's production cycle the unit was released on how recovery works.
I am afraid the HDD is beyond salavaging at this point and the hard drive will need to be replaced. The recovery more than likely will fail on the bad HDD.
Early units came with recovery disks, one of which was labeled Operating System, and some used the F10 recovery and required making the recovery disks using a program (these units did not come with disks).
Is there a disk labeled as Operating System or Disk 1 of X?
If it is Disk 1 of X, then you would start with it, but start with Operating System if there is one labeled that.

Pavilion dv6885se Laptop Has a Blank Screen

Hello,
Having a problem woth my laptop. First the PC specs.
HP Pavilion dv6885se laptop
Intel Core 2 Duo T8100 @2.10Ghz
Vista Home Premium 32-bit
250GB HD
NVIDIA GeForce 8400M GS Video
Starting yesterday (1/8), the laptop would not boot up. It shows a blue screen (not Blue Screen of Death) that gives the option to repair or restore the system. I chose to repair because the restore was going to wipe the hard drive clean and reinstall the base system (factory specs).
I did this numerous times until finally at startup, I pressed the ESC key. Then there was only a black screen. Powering off and back on left the system in the same state: It was on, but no video. I connected the laptop to an external monitor, but still no video. Then after power off/power on a few more times, the screen came up all white. I watched the screen a few minutes and noticed that it was slowly “drawing” multiple colored lines vertically on the screen.
I went to hp.com to search for help. I did see one bit of help. The thread stated something about “crashing the BIOS”. To reset it, power off the laptop. press and hold the ESC key before powering back on. This restored the video somewhat. I was able to see the screen on the external monitor. I was back to the blue screen with options. I did the repair option numerous times and rebooted numerous times until finally the system was up and running.
While the laptop was still connected to the external monitor, tried changing some of the display settings. During all of this time while the laptop was plugged into the monitor, the laptop lid was closed. I just happened to open the lid, and the laptop screen came on. The laptop screen would never come on after power on, but would come on after changing display options and opening the lid.
Today, that no longer works the laptop is on, but the only video is using the external monitor.
Any ideas on what this could be? Also, if it is the laptop screen, would it be better to get it fixed or replace the laptop? Thank you.
Warmest regards,
Fred Tolan

Hello fredtolan.
This sounds like you may be experiencing a GPU issue or a larger motherboard issue. The fact that you're having display issues on both the integrated and external monitors would point to this.
Had you experienced any other problems prior to this? BSODs or freezes?
I would like you to perform a hard reset first. This reinitializes the hardware and can solve a wide range of issues. Try the following.
Shut down the notebook.
Remove battery and AC power.
Press and hold power button for 15-20 seconds three times.
Replace battery and AC power.
Attempt to boot notebook and post the result.
I would also like you to test the RAM and hard drive using the built in diagnostics. You may not be able to do this as I'm not sure if the pre-Windows loading screens will display on the external monitor. Follow the steps in this document and make sure to post the results if you're able to run the tests.
I hope you have a great weekend!

Hp pavilion dv6 laptop has a black screen problem.

Hello,
I dont know how to fix my hp pavilion dv6 laptop.
The laptop is working,have the necessary sounds after i
turn it on,but the problem is that the screen stays always black
..I connect the lap top to tv screen or external monitor and it shows that everything is working properly.
The laptop may have hit a hard surface. The laptop worked well until about 1 week ago when I turned it on and the screen was hazy at first. I turned it off and turned it back on and the screen was completely black but still had the start-up sound. Someone suggested I see if it works on an external monitor and that worked.
Does anyone kow how I can fix the black screen of my hp pavilion dv6 laptop?
I do lots of study with it and have my exams coming up soon. I need my laptop to be mobile with me and not stationed in one place. Thanks in advance for the help!

Hello Chi123,
I see that you are having problems with the display on your HP computer. I would like to help with this issue but I need some information.
Can you provide the model and product number of the computer? Here is a link that shows how to find that information.

Faulty Hinge on HP pavilion M6 Laptop

My wife and I both got a Pavilion m6 laptop and both have the same issue with each one. The left hinge on her lap top the was $550 broke within a year, no damages were made to the laptop, it was well taken care of and it just slowly broke over time until it was all the sudden completely detached. It also caused damages to the screen. We weren't aware it even had a problem until the whole thing was all the sudden unattached. Then on my computer that was about $700+ after normal use and it being also well taken care of the same thing happens. The left hinge all the sudden is completely broken. This should not happen. A computer that is $500 and $700 should not have breaking hinges. We are very disatisfied with these computers for that reason and now we have to take much precaution just opening and closing them to make sure the problem doesn't get any worse. Is there anything that can be done about this problem that should not have happened?

Hello Kooistra,

My pavilion g6 laptop

my pavilion g6 laptop crashed and i turned it off by holding the on/off switch. now when i turn it on it says i have to run a primary hard disk test and when i run it, it doesn't do it? so what wud i do?

Hi,
See if you can run a HDD test from the bios menu as follows.
Shutdown the notebook. Tap away at f10 as you start the notebook to enter the bios menu. Under the Advanced or Diagnostic tab you should find the facility to run a test on the Hard Drive. Post back with the details of any error messages.

My HP Pavilion dv6 laptop wont turn on

My HP Pavilion dv6 laptop does not turn on. Problem with my laptop started couple weeks ago. At that time, when computer goes to sleep mode after inactive for some time, power light and led lights stays on but screen is black. I can not do anything else but to press power button for few second and force turn off. If I turn on computer right away then computer will have black screen and nothing happens. If I remove battery and wait for few minutes and connect the power cord directly to computer and turn on then it will turn on normally and work until it goes back to sleep again. But now, its not even turning on at all. So far I tried hard reset, plugged in to different monitor and RAM test but no luck. Again when I turn on, caps lock and num lock lights blink and fan turns on and power lights, volume lights and wifi lights stays on but nothing on screen. Thank you in advance for any help.

Thank you for visiting the HP Forums! A great place where you can find solutions for your issues, with help from the community!
I came across your post about the Notebook, and wanted to assist you! I have looked into your issue about your HP Pavilion dv6 Notebook and having issues with performance. Here is a link to computer will not start. I would start at the top and work my way down. Mine was fixed with reseating the HDD. Others have had it fixed with just reseating the Memory. Here is a video that shows you how to remove and reseat the HDD and memory. Please note remove any and all USB devices. Disconnect all non-essential devices, as these could cause some issues. You could reset the BIOS with this document selecting the reloading the BIOS default settings. Which has helped others as it restores the default settings. Plug the power adapter directly into a functioning wall outlet. Do not plug it into a power strip, surge protector, or secondary power source as this could cause and issue. Please let me know how this goes. Thanks.

I have a pavilion g Laptop 18 months old. Recently whilst using it, it just suddenly turned itself off. I've connected the mains cable, but nothing is happening. When I press the "on" switch still nothing happens. Any help out there, please?

I have read your post on how your notebook suddenly powered itself off, and that you are not able to power on the computer again. I would be happy to assist you in this matter!
To regain the power on your notebook again, I recommend following this document on Computer does not start (Windows 8) as well as Using and Testing the AC Power Adapter. This should help determine if the issue is with the AC adapter or with how the computer receives power.
If the issue continues after exhausting all of the steps in the documents above, please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.
