Probook 4510s will not boot

I have a Probook 4510s that I got from work. I ordered the original CD's and loaded the OS and drivers. I was getting it set up for my church and had all the software installed. I wanted to remove the Credential Manager so that there wasn't 2 icons on the opening screen and removed it through Control Panel/Program and Features/Uninstall. When I rebooted after the install, the laptop does not recognize the CD Drive or hard drive and does not boot up. In the BIOS set up, I matched the options with another computer of the same model that is working. it now acts like it is reading the CD, but still doesn't boot. The only difference between the 2 is that there are 2 entries missing for HP Quick Look and Prebooth Authentication on HP Quick Look. And there are no devices in the boot order.
I tried moving an already imaged hard drive from another Probook of the same model and it doesn't read that hard drive either. Is there a way to recover or have a damaged my motherboard?

I assume you mean it won't boot from the Recovery cd? Since this is a business class laptop I would suggest posting in the Probook specific forum where they should know more about Credential Manager on business machines and if there is a solution to resolve this.

F8 will not allow booting into safe mode in Windows 8 or 8.1 by default.
You will need to use the recovery media or a Windows 8 rescue flashdrive to access Safe Mode.

Rt speaker of hp probook 4510s is not working

the right speaker of my hp probook 4510s is not working and seems to be replaced

Hi:
That is very odd...
I have the Elitebook 6930p and it has the same ADI audio chip and it works 98% fine with W8.
The only thing that doesn't work is I have checked the box to play the W8 startup sound and it will not on a cold boot, but does on a warm boot (restart).
Other than that, the audio works perfectly.
I used the W7 Pro audio driver from the support and driver page which is the same version as yours in an effort to fix the no W8 startup sound on cold boot, but it didn't help.
You will find that the W7 driver from our support and driver page is actually a newer version than the one W8 installs.
My only other suggestion to you would be to install the latest chipset driver and see if that makes a difference.
First download is what you want.

2009 Mac Pro will not boot up under Windows

I have an Early 2009 Mac Pro system (Mac Pro 4,1) and I've had this system for 3 years already and have been working under OS X with this system ever since I purchased it.
However, when I tried to boot off my Windows disk, something very interesting happens. The Mac Pro WILL NOT boot up off the Windows disk or a known working Windows partition if two monitors are connected. Upon holding down the option key and selecting the Windows partition, I will get a black screen on one monitor (the one connected via Mini Displayport) and the other screen receives no signal and will enter standby and the system is halted. It does not respond to keystrokes, there is no hard drive activity, no measured power increase on the UPS, no apparent network activity, nothing. The only way to exit this scenario (from what I can tell) is to power off the machine, disconnect the display on DVI, power on the machine again, select the Windows partition wait for the system to reach the login window and reconnect the DVI monitor (at which time Windows recognizes it immediately and the system works fine again).
My question to the community is, does anybody know why this is happening and is there a known fix for this? Quite frankly, having to disconnect a monitor just to restart is very tedious and frustrating.
I have two Samsung P2350 monitors attached to an ATI Radeon HD 4870 (512MB, from Apple). One is monitor is connected via directly DVI and the other is using a Mini Displayport to DVI adapter. Both monitors work fine under OS X with no issue. At first, I thought that this may be a driver issue on the Windows side and after installing all the latest updates and drivers the issue is still apparent. From what I can tell, this doesn't seem like a software issue but rather a firmware or EFI issue as this happens before Windows even loads.
If anyone knows of a fix or what to do in this situation, or if you are also having this issue, I would love to hear your input!
Thank you!
For the record, I am running all the latest software builds on the OS X side (10.7.4, not that it would really matter at this point). I have also disconnected all unnecessary equipment in a trial and error scenario but the results are still the same.
The system passes all ASD testing.
The full specification of the computer and all connected equipment are as follows:
2009 Mac Pro (4,1) 8-Core
2x Intel Xeon Nehalem 2.66GHz Quad-Core CPUs
16GB DDR3 ECC 1066MHz RAM (Apple Branded)
Two OWC 120GB SSDs (One for OS X, the other for Windows 7 x64) - These are in place of my optical drives.
4x 2TB WD Black Hard drives for storage.
Two Samsung P2350 Monitors connected via DVI. (One using a Mini Displayport to DVI adapter).

In Windows I am using the latest (12.4) Catalyst Software Suite, 64 bit of course, downloaded directly from AMD's site after installing the drivers from Boot Camp.
As for installing Windows I used an original (not burned) installation media (Disk is in a pristine condition). And yes, Windows is fine, the problem just seems to be getting the system to boot up Windows with that second monitor. However if the "problem monitor" is disconnected the system boots fine 100% of the time and connecting it later after booting the system will still operate properly.
For the sake of arguement I swapped monitor cables and connected the "second" monitor to the mini displayport adapter to verify that it wasn't a cabling issue and I'm still yielding the same issues.
As for GPU testing, I've played games (Crysis, Grand Theft Auto IV, Battlefield 3, etc.) and I've had no issues with the card or stability.
You would think that Apple would try to find a fix for this, especially considering the caliber of this machine.

Macbook Pro will not boot up normally ***Not Normal Problems***

Ok. I have an older 17" Macbook pro 2.33 (10.6 fully updated) that will not boot up in normal mode. When I boot it shows "blocks" of different colors and will not get past the blue screen sometimes. When it does get passed the the blue or grey screen it is a split screen of white back ground with large black blocks seperating the sides. I have tried swapping out harddrives with a known working one with an OSX image on it-no good. I have tried swapping out ram-same thing. I reset the SMC and PRAM-only colors changed in the blocks. I have ran disk utilites disk and permisions with no problems. I can't boot into a restore disk using the c key during boot, It locks up at the same screen. Nothing works except safe mode. I can boot into safe mode and everything works just fine with normal screen and all. Now I tried runing the Lion installer thinking it is and driver issue but I can't get Lion to boot to the hard drive and Snow leopard just reboots back to the same screen. So how can I get Lion to install or Snow Leopard?
What can I do? I noticed this last weekend when I tried to reboot my MB Pro and it started this. Well Apple pushed and update last friday - I needed to restart it again and this happends. I thought it was a logic board at fist until it booted fine in safe mode.

Sorry. What I mean is I selected the SL boot up in the start up panel and it would not boot into the cd. The CD rom sounds like it just keeps reading with it slowly loading from grey screen to blue screen to the Block screen. Almost like it is booting into normal mode from the hard drive.
What I can't understand is why it runs fine is Safe mode?
Also why do I get a " this disk cannot be used to start up your computer" message on my hard drive when trying to install Lion in safe mode? Well why not it's the only hard drive in the computer?
The first screen shot is the Tech tool showing everything passed the hardware test is safe mode.

IMac Late 2006 Will Not Boot Up

I have a late 2006 iMac. The problem I have is that it will not boot up. I press the power button and the light comes on but the display is blank. Do you all think the problem is the logic board?
Thanks in advance,
Andrew

Could be. Is it that the display is blank but the system is running???? If so, what if you connect an External Monitor.
My iBook has been having Logic Board issues similar to what you say though, but it's because of a chip on the lower side of the board that become desoldered. I ended up putting a small piece of rubber onto it to apply pressure onto the chip once I reapplied the case/undercover. It works & I backed up everything, but it sometime acts up again with similar symptoms as your iMac.

I am in mavericks disk utility recovery mode as my mac book will not boot up & stays only on the grey apple screen. When I verify the disk I get open error5 :input /output error on Syst stuck on 1 minute pouring out over 50 error messages & still counting

I am in Mavericks disk utility recovery mode as my mac book pro will not boot up & stays on the Apple grey screen . When I verify disk permissions I get
Open error 5:"input/ output error" on syst with over 50 of this messages & still counting . Disk Utility says 1 minute
But this has been going on for over 10 mins .
I can not verify disk or repair disk .
I have tried to reinstall mavericks operating system but it says my hard drive is locked which is very strange .
Does anyone know what is going on here ?
My system looks like it has been totally corrupted . Thanks Andrew

Could be. The "lock" isn't actually looking for a password.
WARNING: This will completely erase the ENTIRE hard drive.
What you would need to do is boot to recovery > disk utility > select the MAIN drive on the left side > partition > change partition layout from CURRENT to 1 PARTITION > ensure on the right side it says Format : Mac OSX Extended (Journaled) then push APPLY.
Then if it will allow us, close the windows until you see the 4 options popup again and select "Reinstall Mac OS X" select the Mac HD and you should be good to go!

My Mid 2010 MacBook Pro will not boot

My Mid 2010 MacBook Pro will not boot regularly, in safe mode, in recovery mode or from original OS DVD. Is this the logic board?
I've tried resetting the SMC and pram numerous times and even tried switching out hdd's to try and do a clean install on a new hdd.
If I attempt to boot regularly or from recovery drive the grey apple logo appears for a period before the screen goes black and the power LED operates as though in 'sleep' mode. I'm unable to wake it from this state and the same applies to booting in safe mode.
When attempting to boot from the OS DVD that was originally packed with the computer it just freezes on the language select option, this occurs with the other hdd's I have attempted to use.
Any other suggestions to get it working? I fear the logic board has gone and that the repair won't be worth the money.
Thank you in advance.

Hi JRC8.8,
It sounds like you have been on the right track in trying to troubleshoot this issue. You may want to see if your MacBook Pro will boot directly to the Apple Hardware Test, as outlined in the following article:

OSX 10.6.8 server will Not Boot

Hi my 10.6.8 server will not boot. System is a 2009 Mac pro. I have run disk utility from the original server software install disk, ran repair disk, and repair disk permissions. Get some acl found errors have read that they most often are erroneous, Still got the same errors after permission repairs. While booting in verbose mode get the following messages before it stops:

Unexpected error triggering kextd volume watching.
/: Couldn't get description from Disk Arbitration..
I did read on another post here to try to reinstall the os, however when I try to install over the operating system it says I am trying to install an older os and it will not let me install in the same volume.... Although I am confident I have all the data on backups as well have timemachine backups, I would rather not have to erase and install this machine.
Any insight to this problem would be greatly appreciated.

I found that I had a bad harddrive, or at least that is what I think happened.. I did have a time machine backup as well, although in hindsight, I should have made some manual backups of my open directory and the databases hosted on the server. In any case I ended up purchasing "server grade" harddrives and reinstalling the OS on to the new blank hard drives, I was then able to recover from my time machine backup, however, I did have the issue of the restore going over 100%, I tried this several times and the same result with no end after hours and hours. After reading through various forums I found that clicking the mouse button for about 10 minutes straight once it hit 100% finally worked, I was lucky that the Time machine backup had good data on it since I have read several posts saying that Time machine doesn;t backup directoies or any "open files" very well, however I had no problems after recovering from the backup. I do however now backup or archive my directory everyday, and I rely on Filemaker to backup its own databases, however I still use time machine as well...

Build Date 11/26/2007
Problem:
After being shut off for more than 2 hours my computer will not boot up on the 1st try. It goes to a message that says"Reboot and select proper boot device or insert boot media in selected boot device and press a key". I shut it down using the power button, wait for the hard drives to stop spinning, and then hit the power again and it starts up just fine. It will restart just fine also as many time as I want to restart it, after it has been running in windows. Once it is running, it runs terrific, no problems at all.
If you go right into the bios after sitting for a while you see this in the boot sequence, notice there is no hard drives(Nvidia Stripe)in the boot sequence.
After shutting it down and starting right back up this is what you see in the boot sequence. This pic is from a different time, thats why the boot sequence is different.
Here is a short youtube video (2:10 sec) made to help show the problem. (I called it a Cold boot Storage problem for another thread) just ignore that.
Things I have done to try to solve the problem:
1. Update the bios
2.I have moved the boot sequence around, Foppy1st, or CD 1st, ect. and even disabled the [USB:HP Photosm] in the boot sequence, Hard Drives are 1st now.
3.Replaced the Mobo Battery thinking that it was not remembering the boot sequence
4.Checked that the Hard Drives are connected to the correct plugs (6-7) on the motherboard, and that the raid connector JP1 was shorted out for Raid 0 and the blue indicator light was flashing.
* Just a note in this area. I did set up the Raid 0 with a tech from MSI because I was having an issue with the initial set up, and I did use the Nvidia raid drivers that came with the motherboard. Pchas01 in another thread thought that this could be part of the issue because it is not necessary to load the drivers when you set up the Motherboard in the Raid mode.
F10 and look in the Raid Array
5. Pulled the jumper off of JP1 and it just went to the "Reboot and select proper boot device or insert boot media in selected boot device and press a key" screen much faster, but would never boot up after 5 tries. Put the jumper back in and started up on the 2nd try like the normal problem.
6.Went into the On-Chip ATA devices in the bios and Changed the Raid Mode to an IDE, I cannot F10 and get into the Raid Array now, but I guess that is normal.
Now this is what my boot sequence currently looks like.
That is the point that I am right now. It runs great, games are awesome on it. Its just does not want to start up on the 1st attempt.
Thanks for any help on this
Chris aka Fritzpeed novice builder

Thanks for the reply,
I started with the easy fixes first, changed the sata cables, and tried different power supply connectors. Both tests had same results, still boots up on 2nd try. I did not know how soon the problem would re-occur after it has been shut down, my shortest time so far is 25 minutes.
Quote
Why only one RAID channel is enabled? Array can't be detected in that way...
Well right now, it is not even set up that way, in my #6 problem solving, it was suggested that I turn the Raid Mode off and try [IDE] to see if that made a difference,"because I don't need Raid enabled for the hardware raid". It did not, it only booted to the "Reboot and select proper boot device or insert boot media in selected boot device and press a key" window about 60 seconds faster. It is currently set up in this way.
This is how it looks in my On-Chip ATA Devices
How do I check this?
Quote
Does the problem persist when you use Silicon RAID instead Nvidia RAID?
I am still working on getting the seagate diagnostics to work, I am getting an error message before I can even test them.
I do have another question. Why is my HP Printer showing up in the Hard drive test, and also why is it showing up in my boot sequence, is this normal?
And speaking of boot sequences I got in there again just now and saw 2 [USB:HP Photosm]
Thanks again, still working on testing hard drives.

Intel iMac will not boot past gray screen

Intel iMac will not boot past gray screen
my system:
new (month old) 24" intel imac, 2.8 ghz, 4 gb ram.
running: leopard (upgraded from tiger, which was pre-installed at purchase), installed 10.5.1 update right before this huge problem occurred.
install discs on-hand: two-disc tiget set, single leopard upgrade disc.
what led to this:
i wanted to install windows using bootcamp on a 50 gb partition.
at this point i was running leopard 10.5
i followed all bootcamp instructions, printing out the guide, as well. once i got into the windows setup, i was prompted to choose a partition to install windows. unlike the bootcamp guide, which showed three partitions, one clearly labeled "bootcamp", i saw only one partition. not wanting to risk writing over my mac partition, i quit the setup and rebooted the mac os. after some googling around, i looked for firmware updates (didn't need any), and then software updates. i decided to try updating to 10.5.1.
i then ran through boot camp again, deleting my previous windows partition, creating a new one, and moving forward as before. once again, i was only shown one partition to choose from in the windows setup. i exited the setup again to reboot through the mac os, but this time, i was only given a blank gray screen.
here's what i have tried so far:
booting from a CD, holding down the C or D keys: no response (in fact, i have to restart the computer holding down the mouse button to be able to eject the CD)
booting with option key held down: gray screen
booting with option key held down with external bootable firewire drive attached: the firewire drive appears as a boot icon, and i can click on it within a five second window, but then the screen freezes after that time period, and nothing changes
booting into target mode while attached to another mac: gray screen (no firewire icon, and drive never shows up on other mac)
resetting NVRAM: i'm able to hear the boot chimes, but no difference in performance. gray screen every time
Safe boot: nothing but a gray screen
Verbose mode: gray screen
Single user mode: gray screen
Single user mode with firewire drive attached: occasionally (not every time), i am able to get the white on black terminal to show up. from here, i'm able to run fsck, but it appears to only be checking the firewire drive. i have tried several times to boot from here, and once it took me to a blue screen with movable arrow cursor, but it never went beyond this.
is there anything else left to try before taking it to apple?
any help would be greatly appreciated.
thanks,

I'd call Apple support at this point. You'll need
to put this issue on the record.
Call U.S. iPod and Mac technical support: 1-800-APL-CARE (1-800-275-2273)
The wait may be long for an agent to come on the line
so expect that and have some other stuff to do in the meantime.
If you have the applecare protection plan, I'd ask about "onsite"
service.
I like your work ! Good luck !

Mac Pro will not boot - HD and Machine are fine.

Greetings, and thank you in advance for your wisdom.
I have a 12-core Mac Pro, and she has been running like a dream. Once a month I run Onyx. Yesterday I did the same and upon reboot I got the grey apple screen and the spinning progress wheel that never stops spinning.
1. I repaired the HD via Disk Utility. All is fine.
2. The contents of the start-up drive are accessible - so the drive itself is not physically damaged.
3. I installed a new HD and made a copy of this Start-up disk via the Disk Utility. It will not boot from this drive as well.
4. I installed Snow Leopard (still using this) on the new drive to make sure the computer was happy. It fires up fine.
5. Everything is disconnected from the Mac Pro
So, I have obvious, and idiotically damaged the start-up disk using Onyx (assumption).
My life would be much better knowing I could do something that would enable me to boot from my current start-up and that's where I seek your wisdom.
Another question would be: If the above is not possible, if I install a fresh OS on the new drive, and then begin to replace all of the folders from the old drive (applications, library, etc.) will I be able to access my files as I did before. My issue is that I use this for music production, and there are literally close to 100 plugins that all have been registered. Going back through that process again would be days of labor, as some of these were purchases years ago. Tracking down serials would be a task. I think you understand.
So any advice that might prevent me from having to do as I said above will be wonderful.
Thank you all so much.
Lance

Under some circumstances, you may need to reinstall Mac OS X. You can reinstall Mac OS X while keeping your files and user settings intact.
from:
Mac OS X 10.6: Reinstalling Mac OS X
If your Hardware is functioning correctly, and your disk has no un-repaired Directory problems [Hint: run Disk Utility ( Repair Disk ) first] then re-installing Mac OS X modifies ONLY the files that are part of Mac OS X. Your Added Applications, User files (which contain preferences and serial numbers) are not supposed to be touched.

Help! My iPod touch 2G will not boot up!

My iPod touch 2G will not boot.
Heres the specs of the problem:
It turns on with an Apple logo with a spinning wheel under it.
I have tried editing the hosts file with the Apple server codes.
I have tried restoring 16 times. (I log what I do on it)
The iPod has never been jailbroken.
It is an MC model.
It is 8GB.
Its formated for Windows. (Windows 7)
iTunes 10.4
I have tried "The Tiny Umbrella TSS Server with SHSH blobs for iOS 4.1"
I tried "RecBoot" no luck.
My Mom will kill me if I can't fix this. I am going on a 9 hour vacation ride with 7 year old brothers that get really cranky. I leave August 6th, 2011. So I need to have it fixed before then. So i really, really, really need help!

Try uninstalling iTunes and installing the 10.4 iTunes that came out a few days ago. Click start, run and paste "%Userprofile%\Application Data\Apple Computer\iTunes\iPhone Software Updates" without quotes. Find iPod2,1_4.2.1_8C148_Restore.ipsw and delete it. Try restoring again and Tiny Umbrella is only for iPhones. Do not use it on iPod Touch or various errors appear. iPod Touches can downgrade at any time (idk about iOS 5). If it doesn't work, reply. :)

Airport extreme will not boot with USB hard disk plugged in.

Hi there,
I'm using the Airport Extreme Base Station, and I find that if I have a USB hard disk plugged into it, it will not boot up, it only hang-ups with an amber light, and stays there indefinitely. It's not a terrible issue because it can be overcome by unplugging the disk then rebooting, but it's irritating, especially when I'm not home and there is a power temporary outage and my wife can no longer access the internet or I can no longer access my disks over the internet.
Is there a solution to this problem?
Thanks,
Marc

I'm going to have to replace the unit, as I'm unable to turn off DHCP services, which is wreaking havoc on my server based environment.
Considering THIS issue *AND* the major DHCP show stopper, frankly, I'm debating etiher the fire pit or tossing the damned thing into the intersection and watching it be reduced to the trash that it is.
Either way, there'll be 7 feet of pack ice in **** before I buy another Apple networking product.
I'll decide later, with a jaundiced eye, regarding our XServe unit. Might reformat it to Linux...
