HP A6500F Desktop won't boot past blue hp invent screen

My HP A6500F Pavillion Desktop with Windows Vista won't boot up past the blue hp Invent screen. If I press F10 after turning it on it will state "Entering Setup..." but will stop there. When I press Esc, it will state "Entering boot menu...", but will stop there, no matter how long you wait or how long you hold the button. If you hold the Esc button, for example, upon turning it on, I will hear a clicking for some time - but no further action. I have tried removing and replacing the CMOS battery, unplugging everything from the computer and replugging. Computer is ~ 3 years old. About to the exent of my laymen's knowledge and confidence in trying fixes. Any other thoughts out there?

Have you tried removing the memory modules and placing one module in the slot closest to the CPU and then powering up to boo into Windows?
If no joy the first time then pull the module you tested and replace it with the other memory module.
If that produced no positive results then consider clearing the CMOS.
This must be done with the power cord unplugged for your personal safety.
Follow the instruction on this motherboard specification web document. look towards the bottom for instructions and images regarding CMOS clearing. When you do this remove the CMOS battery while you are clearing the CMOS and press the poer button and hold it for a couple of seconds.
Please post your results.
Kind regards,
erico

PowerBook G4 won't boot past blue screen

I've read a couple of posts with similar problems. The jist is, I did a security update/restart earlier and now my laptop won't boot past the blue screen after the white screen with the gray apple. I think I'm on Mac OS 10.4.11 but I had it on auto-update so that could be incorrect.
I've booted from the install disk and run a diagnostic from the First Aid bit in the Disk Utility. It says that there are no errors found and the S.M.A.R.T. status says "verified" as well. It won't let me boot into Safe Mode (although, I could be doing that wrong as I'm not exactly clear on how to do it - pressing S doesn't seem to do anything, but if I press Command + S it takes me to a text listy thing and I've run the "fsck -f" system check (which seems like the same as the disk utility check?) from there and also gotten the "volume is ok" message. There was also a suggestion to run some kind of diagnostic after booting with the D key from the install disk, but I was never able to get the disk to boot from the D key, only the C key.
I'm sure that this is kind of the "same song, different verse," kind of post, but I've not read about volumes registering as okay. I'm a little wary of a archive-and-reinstall as I've not ever done that before (so, if that's the suggestion you have, I would really appreciate loads of specifics on how that works so I don't mess up!)
I've read in several instances suspicion of a hard drive problem but I've not had any slow downs or any crashing. I did travel to the UK for about 10 days, but I didn't even change the time zone on my laptop while there, so I don't think that's it (but I suppose it could be.)
Lastly, I did recently replace my keyboard. A few keys had become non-responsive so I replaced it and have had the new keyboard for a bit over a month.
Suggestions? Ideas? Sorry if it's a repeat post -- just felt like the circumstance was a teensy bit different. And also, thanks very much for any info you can give.

Linsey:
If you can boot your computer into Firewire Target Disk Mode and you have access to a second Mac that supports firewire, you may be able to back up items that have not been backed up previously.
If you are able to back everything up successfully, and you have tested your backup to be sure it is sound, then we can proceed with re-installation of the OS. The best option is to completely reformat and erase the HDD and then install the OS from disk. (I will post complete step by step directions). This will enable you to start with a clean slate/HDD. Your other option would be to use the Archive and Install option. Think it over and let me know how you want to proceed.

MacBook won't boot past the apple logo screen!

So my MacBook started freezing up and I went to restart it and it wouldn't boot past the grey logo screen with the spinning gear. Its pretty old and therefor still has the Leopard operating system. I've been trying to run Disk Repair using a Snow Leopard install disc but it just gets about 30% done and then doesn't go any further. Eventually I stopped the disk repair and just tried installing OSX but when it asks me what drive I want to install on there are no options available to click. I've got alot of unsaved work on this old thing and would love to get it running soon! Any help would be extremely appreciated! Thanks

I've been trying to run Disk Repair using a Snow Leopard install disc
Install discs are "machine specific" .. you can only use the install disc that came with the Mac for repairing the hard disk.
You may not have enough free space on the startup disk.
Follow the directions for starting up in Safe Mode
A Safe Mode boot can take a little longer then a normal boot so be patient.
When you see the Desktop, right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure there's a minimum of 15% free disk space.
If there isn't enough free space, help here > Freeing space on your Mac OS X startup disk
You can use Disk Utility to verify the startup disk from Safe Mode but you can't repair the disk. You will need the install disc that came with your MacBook for that. While you have Disk Utillity open check S.M.A.R.T. status at the bottom of the window. Make sure it says: Verified
When you are finished, click the Apple menu icon top left in the screen. From the drop down menu click Restart.
If you don't have the original install discs you may be able to request a replacement. You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.

Mid 2010 MacBook Pro won't boot past blue screen

I've been having problems booting up my MacBook. I can't get past the blue screen. It went from booting slow at the grey apple logo screen to not booting up at all. Is it a problem with my hard drive? I also have boot camp running as well, but I can still see the boot camp drive for windows and my OS X drive, as well as my installation disk when I have it inserted when I hold the option key at start up.
I'm still able to run windows on it without any problems when I pick the windows drive. I tried different methods from different forums but I'm just not getting through. I tried holding 'c' to boot up from cd and I let it run over night but it never got past the grey apple screen with the gradient wheel (still spinning). I had already used time machine to back everything up before this happened since I was able to boot up properly (but slowly). Can anyone help? It's driving me nuts, and I can't remember what os/firmware version I'm running.

n your signature you said you are running 10.6.3. So let’s assume you are running Snow Leopard.
It sounds like your diagnosis of disk problems is correct. The OS X partition may be corrupt.
Try booting in Safe Mode.
http://support.apple.com/kb/HT1564
Try again to boot in normal mode.
If it will boot in Safe Mode but not in normal mode then you could have some 3rd-party software preventing the boot or you could have a corrupt disk or OS.
Boot as from the startup manager (Boot - option) and then select the installation disk.
Hopefully that will work better than starting with the Boot-C option.
Then try to repair the system disk.
Start the Disk Utility.
Perform the steps in http://support.apple.com/kb/PH5836.
If it repairs OK but still won’t boot reinstall OS X.

14" iBook won't boot past Blue Screen?

Hi,
I have in my possession my Sisters 14" iBook G4. It boots with the grey Apple logo but then freezes at the blue screen. I'm guessing it's either the hard drive or logic board, does anyone have a procedure to follow to diagnose the fault? I don't have the original discs but do have a 10.5 retail box.
Thanks in advance.

Spudnuty - I think you might want to hear this...
I just bought an ibook G4 1.2Ghz "Late 2004" model off of ebay, had the blue screen problem. I bought it because I thought it might have been the OS (freeze at login) and the previous owner didn't know, but it was an actual freeze... actually froze a few times while at the spinning wheel at startup, and would randomly display a dark blue screen sometimes at startup.
I am an ACMT, I decided to disassemble the machine as per the service manual and get it down to basically the logic board, even pulled off the top display entirely. Ran an external monitor via mini-VGA, external HD via Firewire... still froze at blue screen. So I decided something similar to your suggestion - I pulled off the heat sink, only to discover that the conventional way of cooling a cpu/gpu (heating compound directly under heat sink) had been abandoned on this model for some crappy adhesive pads. The pads had a bit of thickness to them, so I decided to cut of a small section of the top shield, fold it into a nice square and flatten it. I then put some heat sink compound on both the cpu and gpu, put the metal "shim" on the gpu and tightened down the heat sink. Guess what? Started up in a jiffy. I put a fresh install of Tiger on it, have been playing multiple Quicktime vids looped for a while now... machine is going strong.
All that to say, shimming works on these later ibook G4 models that get the blue screen, I've confirmed it. Just remove the adhesive pads, shim with something heat conductive (maybe even aluminum foil!), add heat compound and run it for a while.

MBP won't boot past grey spinning gear screen

I tried to turn on my computer the other day, it turns out it wont boot up past the grey spinning gear screen.
First thing I did was reboot from SL install disk, I ran disk utility and tried to verify and repair my HD, both came back with errors... uh oh
I then tried to back up the hard drive by creating a new disk image of my HD and placing it on my USB external, came up with and I/O error... oh sh*t
I tried reinstalling snow leopard and it could not be installed... F*CK!
I tried starting it up single single user mode to see what was happening, turns out it get to the line "dis0s2: I/O error blah blah blah" and then keeps iterating it indefinalty, leading me to believe my hard drive is dead or dying.
so now for the question:
Is it still possible to backup my hard drive in this state? I know, I know, should've been backing it up all along but I'm stupid and didn't. I don't really care about my user setting or anything like that but I use this computer for college and have tons of documents on it that I need.
Also my applecare has expired so i would like to stay away from those genious bartenders.
Any suggestions?

If you have access to another Mac with Firewire then you can connect the two via Firewire cable. You can then attempt to boot your computer into Target Disk Mode. If that's successful then boot the other computer normally. If your drive is accessible it will appear on the Desktop of the other computer. It may then be possible to copy your files if the drive is at all intact. If not you may be able to use recovery software to restore your files. If the drive is not accessible even to recovery software, then you would have to send it to a business that specializes in drive recovery. These are very expensive alternatives - $500 minimally.
You can also try third-party disk repair software. The best of the lot is Disk Warrior, but if the drive has a hardware failure preventing access, then I'm afraid there's little you can do to recover your files beyond sending the drive to a data recovery service.
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten with recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.

Won't boot past grey start up screen.

All of a sudden my Itunes quit and wouldn't reopen so I thought a restart would be the fix. It turned back on but then got stuck on the grey loading screen. I tried all the hold down button combos and nothing worked. I am out of warranty and am a poor college student. Any advice? Please help.

Welcome to the Apple discussions.
You'll need the original OS X discs that came with your system. Insert the first one, and boot holding the C key down, which will boot from the OS X disc. From the menu bar, choose disk utility and repair permissions and repair disk. Any messages on repair disk? If it concludes successfully, reboot. Working now?
If not, you should run the Apple hardware test. Insert the OS X disc that has 'AHT Version x.x' in small print on the label. Reboot holding the option key down, choose Apple hardware test, click the arrow pointing to the right, and follow directions. If prompted, choose the extended test. Does this give you any messages? Note, if you have either of the TechTool programs, they can do the same testing.
Post back the results and we can help further from there.

My HP Pavilion A1710N wont boot past the HP INVENT Screen

I have a HP A1710N desktop, Ive had it for little under 6 years now and recently replaced the motherboard, hard drive, power supply, and added 5 gigs of ram to it, and upgraded from the 32 bit operating system to the 64 bit windows vista home premium, my problem is this, I reformated my hard drive and after I reinstalled and updated my computer I rebooted, after that all it did was start up at the HP IOnvent screen and didnt do anything, I can hear and see the fans going and hear the hdd going, my dvd drive opens and so on, but it would not boot any farther, I took everything out and cleaned it up and reordered the ram chips, and still same thing.
I then took everything except the dvd drive, mother board, and power supply out and put into a differant computer and everything works perfect.
my question is this, could my power supply cause that or do I need to replace my mother board agian
my computer specs
Hp A1710N
Athlon 64 X2 (W) 4200+ 2.2 GHz
1tb hdd
1tb external hdd
ati msi hd 4550 graphics adaptor
6 gig ddr2 ram (2x2 gig + 2x1 gig)
250 watt power supply

this problem is realy easy to fix. first take the cmos battary out. next make sure there are only two ram stick in must be 2gb . plug them in on the right side also make sure the power cord in unpluged . then let it sit for 5 mins or so. plug it in with the cmos batarty still out. it will turn on but the monitor will not show anything thats a good thing tho. unplug again then put the cmos battary back in . make sure the hard drive is pluged in good. plug back in and it will start all by its self. and boot up. it will ask you to start normal or to check the start up. run the check and it will restart and work good. after that run window disk clean . windows up date. it shut down and put the ram in if you have more. allways make sure its unplug . the static from you and your hand may cause it to do the same thing over again. this is why the problem happen in the first place. some power supply's have a on/off switch you must still unplug the power cord. and wait 30 sec or more to let the power supply drain or dump the power out. THIS WILL WORK 100% of the time.

IBook G4 suddenly won't boot past the "booting OSX" screen.

My iBook G4 suddenly died and now won't boot past the "Starting OSX" screen. The blue bar goes all the way across but never moves to the next screen. I have my original disks, containing OS 10.4.5. I am trying to boot from the disk, but just keep getting the Installer program. When I try to choose a startup disk, it still won't start. Any help or ideas? This is urgent.
BTW, I am a photographer and was workig in PhotoShop7 -- a program I use all day, every day.

Start from the install disc again and choose Disk Utility from the menu. Highlight the drive on the left and click Repair Disk. If it reports errors and repairs made, repeat the process until no errors are reported.

Ideapad K1 won't boot past Lenovo screen

HELP! My IdeaPad won't boot past the lenovo splash screen. Here's what happened...
It has an AOSP version of Android on it which has been running fine for over a year - never had a problem with it. Yesterday, I tried to awake it from sleep but nothing happened. So I held the power button down until it switched off. I then restarted it and got to the password screen. After entering my password it became unresponsive - it just stalled with the desktop screen on. I gave it 10 minutes but it never became responsive again.
I reset it by holding the power button again until it switched off then I switched it back on. It has never got past the Lenovo splash screen. I've tried booting it loads of times, giving it a full charge, taking the SD card out, giving it a rest, leaving it booting for the whole night...nothing has worked, same result.
I also tried connecting it to the computer and using NV-Flash to put a new image on. It seems to work okay but when it re-boots it still won't get paast the Lenovo splash screen.
I'm desperate for anyone to give me some hints and tips as to where to go from here. Any help would be greatly appreciated!

Hi,
I am having a similar problem. My 3 month old ideapad u510 froze last night while surfing the internet. nothing worked as far as getting shutdown menu in windows 8 to even work (just froze), so pushed power button till it turned off. immediately afterward, tried to boot by pushing power button and it just stopped booting at lenovo screen.
i've tried to boot a few times since and sometimes i see progress thing (circle of lights...similar to status bar) going other times not. i am not sure what key it is but can get to bios screen sometimes too. was hoping there was safe mode boot in bios but doesn't appear anything thats useful so didn't change anything. it just doesn't boot to windows after exiting bios.
my hunch is that i need a bootdisk or sort. importantly, would like to avoid resetting or refreshing, etc.. until have opportunity to get data off harddrive if possible. some important stuff on there that need to get off first.
Help is very much appreciated.
Thanks,
J

G4 won't boot past grey apple screen

Hi. I have been having the same issues with my G4 15". I'm frustrated. The whole thing started with stalling during applications. So I decided to reinstall my OS X 10.5. After reinstall, I copied my saved files from my "My Book" drive back to my hard drive. Stalling issues returned. I reinstalled again. still had some stalling issues, so I performed disk utilities. I repaired permissions. SMART status is verified. System still ran extremely slow. So, I followed directions on apple support for resetting the PRAM and NVRAM. After I did this, the computer won't boot past the grey apple screen. I have reset the PRAM and the NVRAM again. Still nothing. I rebooted up from OS install disk. I performed disk utilities repairing permissions and repairing HD. I did this for both my drive and the computers drive. I choose restart and again the grey apple screen. I have been trying to get this thing going for a week now. I'm near tears. Cornelius or anyone, can you help me? It says no errors are found, SMART is verified. But I can't get the computer to boot unless it is from the CD. Is the computer confused on where to boot from? Or is it shot? HELP ME PLEASE, before I play frisbee with my dear beloved mac!!!! It seems like this ALL started happening after I installed the update 10.5.8. I had ZERO problem prior to any software updates!!!

There have been report of some external drives/enclosures that do not work as a boot device. Not sure if the MyBook is in that category or not, just make sure that there is nothing else plugged into the Powerbook then try again.
Does the WD need its own power to be plugged into an AC power source? Try the other firewire port
I have one more question for ya... You were able to load OSX on this EHD using the OSX install disk in the Powerbook? And the installer saw the EHD with no problems?
If non of the above works try booting while holding down the x-key, this should force it to look for an OSX volume, not sure if it works the same on an EHD but worth a shot.

Powerbook won't boot past apple screen, disk utility can't repair

Last night I applied the most recent software updates, I don't remember exactly what they were but there was a Java update, a security update, a quicktime update and an itunes update. after the required restart, my powerbook g4 won't boot past the apple icon screen.
I can't boot it into safe mode or single user mode.
I can start it up in target disk mode and transfer a handful of files/directories at a time before it hangs.
When I try to run the repair in Disk Utility against the target disk, it gets about halfway before the following:
Verify and Repair disk “Macintosh HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid sibling link
Volume check failed.
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
the disk doesn't make any grinding or anything, just a few clicks when it tries to boot but nothing bad sounding.
Is my computer hosed? Is it worth bringing it to the genius bar?

Hi, Pat. How much time did you give DW to complete its work? Locating the data it needs to rebuild your directory can take a while — that's the step at which DW far outperforms other utilities. It digs deeper and tries harder than anything else, and that can take a long time. The longest successful DW "fix" I've seen reported here in the seven and a half years I've been participating in Apple Discussions was *14 days* of continuous work to find the necessary data and reconstruct a hard drive directory from it. That was after all other disk utilities had been tried and had failed; it was the user's last hope to save data that hadn't been backed up anywhere. If you haven't allowed DW at least a few hours to accomplish its task, give it another chance. And don't try to use the computer for anything at all while DW is working.

Macbook won't boot past main apple screen

I was using my computer this morning (13" black Macbook that I've had since December) and it was working fine until I closed it to go get something to eat.
When I got back and opened the lid again, the screen was black, as if it was off, but I could make out the outline of the Apple logo in the centre. So I turned it off, gave it some time and turned it back on. Now it won't boot past the main Apple screen, where the little timer thing spins and spins and spins while apparently nothing else happens.
I left it alone for a couple of hours, thinking maybe it was overheated, but that didn't make a difference. I tried taking the battery out and restarting it, but that didn't work either. I called Apple, but my parents opted for Future Shop's warranty instead of Applecare, so they told me to search the website as "the issue is well-documented," since I have no tech support with them.
I've searched around to see where this is posted or if it's been answered a billion times before, but it's 35C in here, and my rage/frustration are ruining my ability to be rational, haha.
Anyone experienced this before / is there a resolution that doesn't involve me being without my computer (which is like sweet, sweet crack to me) for an undisclosed amount of time?
Thanks in advance,
Emy
Oh, and I'm not sure about the operating system version beyond that it's OSX and I regularly install whatever updates they tell me to.

Maybe Disk Utility can repair the disk this way:
-Search your installation DVD's.
-Insert the disc 1 and sthut down your Mac
-Start your Mac again while holding down the C key
-Now your Mac should boot from the CD, this can take some time.
-After a while you will see a installation screen where you can chose a language.
-Chose English and continue.
-Then click some time's next and agree with the "Software Agreement".
-Open Disk Utility. Top menu bar --> Utilities --> Open Disk Utility.
-Select your hard disk in the list of disks and volumes on the left side
-Go to the First Aid (tab somewhere on the right).
-Click the button to verify the permissions.
-Then Click the button to repair the permissions.
-Click the button to verify the disk.
-Then Click the button to repair the disk.
-Exit the Disk Utility

Cisco UCS C220 MS SFF won't boot past BIOS screen with 2x1.2TB SAS drives installed

We have been running a few of these servers with only a 500GB 6GB SATA 7.2K drive installed with all VM's (Hyper-V) sitting on an attached SAN.
For various reasons we needed some local storage on the server and installed 2 1.2TB SAS drives (10K 2.5"). They hot installed okay but the server had to be brought down to enter the MegaRaid software to configure the RAID.
Unfortunately with the drives installed, the server won't boot past the initial BIOS screen and certainly doesn't get to the RAID screens.
Does anybody have any idea why this would happen? Is there some BIOS update required to support these drives and/or MegaRaid software upgrade?
The servers are up and running at the moment so I can't find the version of the RAID software running.
Thanks
Larry

Hi Lauren,
If you don't have a PCI or a mezzanine based controller and you are using the embedded raid controller you need a chip for the embedded raid controller to support SAS drives. By default the embedded controller only supports SATA drives. See page 9 of the link below
Please let me know if you are not using the embedded controller
