Unable to boot off of wall power

Ok, working on a an HP DV7t 1000 series. The computer will boot off of the battery, but it is not charging te battery when plugged in. Took battery out, tryed to boot. No good.
Took computer a part, disconnect the DC power jack, measured the voltage from Black to Red and Black to white, has true voltage. Reconnected power jack to mother board. Measer power at the battery port, measurements seem good. When I short the second and third post from the right, the LED light indicating that it is charging starts to blink. Connect the battery, LED doesnt blink.
The Question is, what is causing the battery not to charge and the computer not to boot off of wall power?

Hi @Scully397 ,
Welcome to the HP Support Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I saw your post regarding the problem with the notebook not booting when connected to the wall power. You have been pretty thorough checking the notebook jack but it looks like the problem would be the AC adapter itself. There are two potential part numbers you can use to order a replacement. If you have the 65-W AC Adapter then the part number is 463958-001 and if you have the 90-W Adapter then the part number is 463955-001.

2009 Macbook unable to boot in any fashion

I was recently given a broken Macbook from a friend who didn't want it anymore, and had no interest in fixing it. It's a 13.3" Macbook from 2009 with a 2.0GHz Core 2 Duo processor, 2GB of 1066MHz RAM, and an Nvidia GeForce 9400M. Since I can't get it to boot, and am not super familiar with Apple OS's (I'm more of a linux guy to be honest), I'm not entirely sure which version of OS X it's running, but from the production date my best guess would be Snow Leopard.
So now to the problem.The first time I turned it on it booted to the login screen with no problem. Unfortunately that was the only time it worked. Now when I press the power button, it goes to the gray screen with the Apple logo, and the progresses to a blank blue screen. After approximately 5 seconds the screen goes black, and flickers in a somewhat periodic manner until I manually turn off the computer. In an attempt to fix it I tried to boot it in safe mode, but experienced the same problem. Next I tried to boot it off of an Ubuntu Live USB, but was unable to access the boot menu, and was therefore unable to boot off the flash drive.
After doing a bit more research, I tried resetting the PRAM and NVRAM. I started the computer, pressing and continuing to hold the "option-command-p-r" key combination before the gray screen as per the instructions given at http://support.apple.com/kb/HT1379, but encountered the same progression of screens as I previously had, thus the only reasonable assumption is that it did not successfully reset. Next I tried resetting the SMC. I removed the battery, disconnected the the power adapter, and depressed the power button for 10 seconds, but this as well had no effect.
Next I tried to run fsck by booting into single-user mode. Though it booted to what appeared to be the functional single-user mode command line prompt, after the line ":/ root#" I was unable to type any commands, and once again had to manually shut down the computer. On another attempt to boot is single user mode the message
:/ root# AppleIntelCPUPowerManagement: initialization complete
Broadcom2045FamilyUSBBluetoothHCIController::start booting in single user ... will wait for later
[HCICcontroller][configurePM] power parent ready after 1 tries
and another try yielded a last line identical to the first line of the above message, with the lower two lines appearing above it.
I then, tested the RAM by trying all 6 permutations of the two 1GB sticks. With each configuration I tried to boot the computer normally, in safe mode, and in single-user mode, but in all 6 configurations the computer behaved exactly like (with the exception of it spending more time on the gray screen with Apple logo during the normal boot procedure when it was being run in the 4 positions that had only 1GB of RAM rather than the standard 2GB, but that was to be expected) it had been.
Five notes of interest.
1) The power adapter she gave me with it is an 85 watt model, whereas the stock power adapter appears to have been a 45 watt version, but this should neither have contributed to my current problem, nor caused any damage to the computer whatsoever
2) The computer is unable to be turned on without being unplugged and removing the battery first. That is to say, after an unsuccessful boot attempt I must remove then replace the battery in order to try again.
3) The battery is not defective, and is capable of holding a charge
4) The screen was replaced at some point in the last 2 - 3 months
5) I have read of a similar problem occurring with Macbooks that have had a new hard drive installed, but as far as I can tell the hard drive in it is the stock 160GB one that came stock with the computer
Thank you for taking the time to read this post, and for any advice or help you can provide.

Despite nobody having answered, I'll keep updating.
I noticed today that as well as having to remove the battery each time before trying to start the computer, it also will not start if the power adapter is plugged in.

DVD Drive not being able to boot off of. Not seen in Boot Menu options in Bios.

HI Guys,
I am having a serious problem here and Lenovo Support has been bouncing me around between Hardware and Software Support.. They are extremely uneducated and I miss Dell Support. They are not educated about their own product and it saddens me. Here is my problem and there should be a simple soulution. Please help.
1) I have a IdeaPad U 430 Touch laptop. It came pre installed with Windows 8 Home. Unfortunately Windows 8 Home did not work with any of my Business Applications..
2) I completey wiped my Hard Drive using Government Software to write 1 and 0's.. I installed Winows 7 Ultimate successfully by booting off of my External USB DVD Drive.
3) After sucessfully installing WIndows 7 Ultimate I upgraded my Bios to the latest version.
4) I am able to see my DVD Drive in WIndows 7 at the Operating System Level.
5) This is the problem I can see the External USB DVD DRIVE in Windows 7 Operating System Level. Its in Windows Explorer.. However I am unable to Boot off the DVD Drive. When I reboot the latop and press F12 the External USB DVD Drive is not listed there. This is the Same External USB DVD Drive I used to wipe the Hard Drive Clean and install Windows 7 successfully.. My Bios is set to Legacy..
6) Please Help.. Someone

hi Agent0
Thanks for Posting!
Upgrading the BIOS might set off something.
Check under Exit TAB and see if you have OS optimized or OS optimal Settings.
      Change it to other OS or Disable.
      Save and Exit
Boot into BIOS again.
      Check Boot Tab if you have now a Boot mode and Boot Priority.
       Set those to Legacy / Legacy first.
Look for Secureboot and disable it.
      Save and Exit and try the F12 and see if you can have the ODD drive as an option again.
Regards
Solid Cruver

[Solved] Unable to boot Arch off SUSE GrUB

Hi,
I have several OS installed on my machine. I used to boot everything including Arch but BSD, Solaris & PCBSD with GrUB2 off UbuntuStudio. Earlier today I installed SUSE GrUB on sda and now I am unable to boot Arch. I've used SUSE GrUB earlier and was able to boot Arch off it.
Here is my menu.lst

HT201401 i am unable to switch off iphone with the power on/off button.

i am unable to switch off iphone with the power on/off button. Though I can feel the sense of the button, but it doesnt work.

If there is Warranty or AppleCare make Genius reservation or set up service and take or send to Apple for resolution. If no coverage, Apple charges $199 for Replacement iPhone 4S. You can use Assistive Touch. Settings App > General > Accessibility > Assistive Touch > ON > tap new white screen button > Device > Lock Screen. This can be used to turn iPhone OFF, hold down on the Lock Screen icon until "slide to turn off" appears. To turn iPhone ON, connect to power, charger or USB port of computer.

Unable to boot normally - Always need to boot with Single User Mode

Hi Community,
Since last few days, I am unable to boot my Macbook Pro normally, running latest version of OS X Yosemite. When I boot, it goes to grey screen with Apple logo and progress bar, once the progress completes to 100% (after 5-10 minutes which is very longer than usual), it asks me to 'Select language' which seems like fresh installation of OS X. In that case, when I click next and it doesn't detect my SSD (blank list of select installation disk/drive).
After reading some threads, I found work-around and always need to boot into Single user mode (by pressing Command+S during power on) and then need to run following commands...
/sbin/fsck -fy
/sbin/mount -uw /
"device is write protected" numerous times
reboot
and then only it loads OS X and displays login screen. This happens all the times and I need to follow above steps always to get login screen.
How can I fix this?

Please help me out here. I tried booting it off a USB flash drive with ATV flash but that gave me some errors and prompted me to login with username [email protected] with password frontrow
But I am not sure how to get to login using a suitable input. I tried to telnet it using my PC over network but I dont think it has initialized anything (like wifi or network) at the prompt. Would it take USB keyboard input? All I can do is remove the power and restart it with the usb flash out and get into then get into the recovery loop. I am not sure replacing the hard-drive would help. Any help would be greatly appreciated.
Thanks

S400 unable to turn off wireless

Hi , I am unable to turn off or on wifi/bluetooth with the f7 key(alternatiely the wireless key). wifi and bluetooth are enabled always whch i feel is power consuming when not required. the key seems to be unusable.
netbook config is :
i3, 2gb ram, atheos ar9285 wireless lan adapter, atheos ar3011 bluetooth adapter
i have installed both the wireless drivers from lenovo support.
what should i do to correct this.

hi Pravinrajpaul,
Welcome to the Lenovo Forums.
If you're running Windows 8, pressing the Airplane Mode (F7) turns OFF both the Wireless and Bluetooth radio. If you want to turn off just the Blueooth though, you will need to do it manually by:
1. Opening Device Manager (press Win Key+X > choose Device Manager)
2. Expand Bluetooth Radios then right click > disable the blueooth adapter.
3. For the wireless, choose Network Adapters under Device Manager and right click > disable the wireless module or boot into the BIOS by pressing the One Key Recovery button and under the Configuration Tab, set Wireless LAN Support to Disabled.
Hope this helps.

do a reset, hold down the home/power button together until you see the apple logo and then release, then wait for the phone to boot back up. Then try powering off your phone.

[Solved] Unable to boot (startup job is running)

Hi there!
Today I went home and tried to boot my laptop there, but was unable to boot Arch.
Before I went home I did a system update using ' sudo pacman -Syu ' and shut the laptop off normally. Right now I get the following message whilst booting:
" A startup job is running for dev-disk...25EFDCE0.device"
It fails after 1 min. 30s and shows a time out error for dependency /mnt/6776F38425EFDCE0, and refuses to boot. I waited for 5 min. but the only thing working at that stage is the shut down button (which appears to enter a normal shutdown mode).
Grub 2 is functioning; Windows 8 boots up fine (same HDD); though all options to boot arch fail because of the 'startup job error message'.
Do any of you know how I can fix this, or how to boot/fix arch such that I can attempt to fix it? Based on a search trough this forum it might be an error in FSTAB, although all cases reported on this forum appear to boot normally after the 'a startup job is running 'error message'.
Many thanks.

Thank you for your response.
Changing the UUID's to /dev/sdaX did not do it's magic, unfortunately. The ' a start job' message is gone, the boot however gets stuck at
/dev/sda2 clean .... (beginning of boot)
Unfortunately I did not properly save the back-up of my fstab file, so the initial set up is lost. Was able to acces arch using alt+f2 and have restored it manually with
lsblk -f
It currently looks like this. I did have a line to automount my data partition (/dev/sda4, label: Data), but didn' t know how to restore that one as that line got deleted too. My gut says this automount was causing the initial error, but it should boot up normally with the current fstab file, right?

Xserve Crash - Now won't boot off either SAS Drive

Hi all,
My Xserve (2008) just crashed about an hour ago - turning on the screen connected to the Xserve showed the entire thing had ground to a halt, meaning I had to hold the power button down, thinking it just needed a reboot.
Upon re-booting, it just started flashing the "No OS" ?-inside-a-folder icon.
Booting off the system DVD doesn't seem to work, it loads as far as the first blue screen and gets stuck.
I've successfully managed to boot off a MacBook Pro via Target Disk Mode, and upon startup was presented with two dialogue boxes saying the disks I had inserted were unreadable by the system.
Can it really be true that BOTH my SAS drives have failed at the same time?
One was the boot drive, the other a cloned backup updated every other day.
Unfortunately I don't have a backup of the backup, though somewhat luckily this is just the OS. All the 'data' is stored in RAID5 arrays.
Any ideas what might be happening? Something inside the Xserve itself?
I'm currently installing Snow Leopard Server onto a LaCie FW800 drive through a Mac Mini, should be done in about 25 minutes. I'll then plug that into the Xserve and try to alt-boot off that, see if I can get to DiskWarrior.
Any help is appreciated,
-Robert

Nicolas, welcome, did you boot from OS 9.1 or 9.2 for the firmware update. And exactly what happens when you attempt to boot from the external.

Black Screen - Get Chime - Can Boot off HDD using another Mac - iMac 24in.

Hope someone can help me here, as I'm at my wits end.
I've got two issues, one with my MacBook Pro 17in, 4GB RAM, 160GB 7200rpm (2008) and another with my iMac 24in. 4GB RAM, 500GB 7200rpm (2009).
Firstly the MBP, left work on Thursday last week, got home, powered up the MBP and got a black screen!!! Tried resetting PRAM, SMC, booting in safe mode, removing and re-installing RAM, removing battery and mains power and leaving off overnight etc etc, yet nothing happens. Benn all over the forums and have not found any solution to get my beloved MBP working on it's own. I can boot off the HDD using another MBP 15in, re-install Snow Leopard and as far as I can tell the HDD is fine, as I have run disk utility and it tells me the HDD is OK.
I can't figure this out and it's doing my head in, as I use this laptop for business use and just can't afford to go out and buy another Mac. I should point out that this MBP never had any issues when running on Leopard, but ever since I upgraded to Snow Leopard, I have had nothing, but trouble. I did a clean install, in fact I have done it at least twice, even erasing the HDD securely, both at 7pass and 35pass, yet I have had permissions issues regularly and on the odd occasion, I have also had the problem of the HDD not being recognised.
The iMac is nearly the same, but the screen is working, although the iMac doesn't see the HDD no matter what way I do, again, reset PRAM, SMC, safe boot etc etc. In truth the iMac has been a lot more unreliable, but with the screen working, if I can get any solutions here, then I'll be working to work on that without the need or hassle of working via another.
I think that the MBP is only just still under warranty, but the iMac definitely is, but I need at least one working for business use, so really only want to let Apple have one at a time to look at/repair etc.
Ideally, as the HDD is working in the MBP, if I could get a solution to the black screen issue, then I could do without the iMac for whatever time it takes, so if there is anyone out there that can help, I'd be so grateful.
One last thing, when I bought the iMac 24in., I also bought an iMac 20in., but I never upgraded the 20in. to Snow Leopard and to this day, it has worked flawlessly, without a single issue ever.
Perhaps, I'm getting paranoid here, but there seems to me to be a link between the ongoing and regularly occurring problems with both Macs ant the upgrade to Snow Leopard. Why also, or is it just pure unadulterated coincidence that both the MBP and the iMac 24in have failed at pretty much the same time??!!!!
I'm going mental here, so I hope someone out there has a better fix, then me overdosing on Prozac!!
PS
I'm not a mac expert, not good with a soldering iron either, but I'm capable of following good instructions.

Using Snow Leopard forum is probably your best bet.
I don't care if someone has 20+ yrs, I still like having a good troubleshooting book/manual handy.
Mac: can't get by without bootable backups, even if you use TimeMachine, clone your system. Save you all this fuss and work.
Then invest in high quality disk repair and maintenance program.
Disk Warrior / TechTool Pro 5 / Drive Genius 3 - top 3 probably
There are always going to be normal items you just ignore with Repair Permissions. Useful to do once in a while but not magic. Same with SMC and the rest. Running disk repair is one of those things that it seems should be done before there is trouble, not after, and a weakness in HFS file system and disk directory.
Apple Support is a good place to start looking and then hardware category.
http://www.apple.com/support
http://www.apple.com/support/imac /macbookpro etc
Make sure all your software is current, don't install anything you are unsure of or can do without.
Run Apple Hardware Test off your OEM DVD specific to the Mac.
Now, have you Googled for this?
have you looked at reports about 500GB drives used in some Macs that had issues and were offered firmware update for the drive?
Considered just using another drive connected to iMac?
You can overheat a hard drive with needlessly running 7 and 35-write pass, besides which the best way to map out bad blocks is not Disk Utility.

Hi there,
we've successfully restored a MacOS 10.6.8 server image to an Intel Xserve. However, there seems to be a boot cache issue. Sometimes I am unable to boot and MacOS Server won't restart. The Xserve restarts twice on the gray Apple screen. Than it's hanging on the gray Apple screen. no disk activity for minutes. I've waited 30 minutes. I had to power down the server. After that the server boots normally. no errors in verbose mode during startup.
I am using 3 volumes (all 3 using the same system clone). All Bay drives using the original Apple Disks. They are brand new. <29 hours.
Resetting the NVRAM a couple of times didn't solve the issue. The booting error is reproducible. This system runs fine and it's really clean. I just installed the latest MacOS 10.6.8 combo Update
I don't know what else I can I do? I really appreciate any help on this.

Sorry for the delay in responding.
Thank you, Peter. The Xserve running fine so far. We've had any boot issue.

HP Pavilion dv6 Notebook PC unable to boot recovery disk

HP Pavilion dv6 Notebook PC unable to boot recovery disk. First when I power on my notebook it goes straight to the launch recovery or launch Windows normally screen. When I choose start windows normally, it goes to the window screen and freeze. When I try to launch the start-up with windows 7 start-up disk, the computer will not load the files. When I tried to complete a hard drive test, it failed with a failure ID 9UXNXA-55E65V-XD003G-60XR03.
I'm looking for a solution, can someone help?

Hi:
It sounds like you need to purchase a new hard drive for your notebook, and reinstall the operating system with your recovery disks.
When a HDD fails a diagnostic test, it normally means it is done for.

[SOLVED] Unable to boot after kernel 3.9.2

After update to 3.9.2, I was unable to boot. After bios screen I see a black screen with only a white cursor and it hangs forever.
I was able to boot from a usb live image, mount my fs, arch-chroot and downgrade to 3.8.11, then it all worked.
I am using gummiboot with EFI, from SSD drive.

Can a Mac Pro boot off a MacBook Pro in Target Disk Mode?

Summary: "Are you able to boot a Mac Pro off of a Mac Book Pro in Target Disk Mode?" OR "Will a Mac Pro boot off an OS X install that was made on a MBP?"
Details:
I'm finishing a music project that was created on a PPC G5 Quad computer and going to a studio in Santa Monica to complete the final mixdown. My 3rd party software plug-in configuration is unique, and the studio doesn't have all of the software instruments that I do on their 8 core mac pro. My G5 software installation is mirrored to my MacBook Pro, but the MBP doesn't have enough CPU power to play the project back.
Is it feasible to have the studio's 8 core Mac Pro boot from my MacBook Pros hard drive? Essentially, we'd be using my OS and software on their powerful CPU / hardware. I figure, since they are both Intel builds of OSX, this should be do-able.
I don't have access to the Mac Pro until I show up to start working.
Thanks for any input / suggestions!

The MacBook Pro boots fine in 10.5.8, and loads the Logic project without any faults. The only issue is that a CPU shortage occurs when you attempt to play the sequence.
Like you suggested, I performed separate UB installations of all the needed software on the MBP solely so I could move Logic projects from one computer to the next without a hitch. (Actually, DropBox does this for me). Migration assistant was not employed in this process due to the PPC / Intel issues you noted.
I didn't need to mention the G5 as it appears to have caused some confusion based on Kappy's reply, but I did want to explain my work flow thoroughly.
It sounds like booting the MacPro from my MBP is feasible. I'll mark this topic 'solved' and head over to the studio tonight. I'll post here any anomalies from the session (if any).
THANKS~!
