[e330] wont boot without external power

My lenovo e330 started having problems with HDD.
Most of the time when trying boot without PSU connected got windows error saying "A disk read error press alt ctrl del to restart"
Also when working without PSU on low level of battery it tends to crash with BSOD sayin it can't store memery dump becouse of disk error.
Smart show CRC udma erorr count almost 4000.

Boot the "old white MB" from the external, and double-check the version of OSX on it. Make sure it's not earlier than the version that came with the MBP. Check the MBP's DVD, or plug it's serial number in here: http://www.appleserialnumberinfo.com/Desktop/index.php
If it's newer, while it should boot the MBP, it's possible it won't in some cases. See: [Mac OS X v10.6: Issues after restoring a Mac from a Time Machine backup made with a different Mac|http://support.apple.com/kb/TS3243]. While that's talking specifically about a Time Machine restore, the issue is the same.
You might be better off putting a copy of the latest Retail Install disc you have (as long as it isn't earlier than what the MBP came with) on your "repair drive," instead of an installation of OSX. Just restore it from the DVD via Disk Utility.

Wont boot if external hard drive is on

PC wont boot if external hard drive is turned on. If I turn them off boots fine. This has happened since day one.

Hi,
Turn "them off" implies more than one.
You might be experiencing one of three issues or all or them.
1. The external HD needs a firmware upgrade to be compatible with your PC
2. The BIOS boot order is incorrectly set which is typically not the situation with new PCs.
3. The external HD is drawing excessive current from the USB port.

MBP i7 17" wont boot from external CD/DVD

I have installed a second hardrive in my mbp using the optibay. Since then ive been trying to install windows on the second harddrive, but it wont boot from the windows cd. After some testing, it turns out it wont boot -any- cd from an external cd/dvd drive.
When i put in a bootable cd and boot with the option key, it does recognize the cd. When i select it, it starts spinning up, stops, and i get a grey screen with an flashing apple/failed sign.
I have already tried the following:
- Reset PRAM
- Use the superdrive i removed as USB cd/dvd drive
- Use a different USB cd/dvd drive
- Tried to boot off a bootable USB memory stick
- Installed rEFIt boot loader.
- Tried the (USB) superdrive on a previous model 15" MBP, and it boots without problems.
Im at a loss what else i can try. OS X installed perfectly when the superdrive was still connected to the internal SATA connector, but i dont feel like switching the whole thing back. Not to mention i wont be able to install windows on the secondary drive.
Maybe i could try an ExpressCard SATA controller? Or would that be a waste of time/money? Im also considering installing through target disk mode, but im afraid ill run into all kinds of trouble.
I hope you'll have some ideas!

I think can wrap this up.
The OS X Installer that came with my MBP did work on the external USB superdrive. So it appears the same thing applies for any USB connected device: only OSX installer will boot from it.
As for my initial booting needs: i have successfully installed Windows using bootcamp, though i used a workaround so i didn't have to boot from cd. For anyone who wanders around here and wants to know:
- Created a 10GB VMWare disk image for Windows
- Booted windows install disk inside VMWare
- Upon first reboot i shut down the virtual machine
- Connected the 10GB VMWare disk image to a Debian virtual machine
- Ripped mbr using: dd if=/dev/sdb bs=1 count=446 > mbr
- Copied it to my mac, and installed it to my drive using: fdisk -u -f mbr /dev/rdisk1
- Copied over the VMWare disk image to my Bootcamp Assistent created partition using: dd if=/dev/sdb1 | ssh root@mymac "dd of=/dev/disk1s3"
- Used WinClone to make an image of my Bootcamp partition, and immediately restored it. This fixes some windows issues for the new partition, and resizes it to fit your bootcam partition
- Reboot into windows and the install will continue!
Some tweaking of these commands are needed. If you don't know what you're doing: don't.
Any questions, feel free to contact me.

Envy DV7 laptop will not boot without the power cord being connected

My laptop won't boot on its own even when the battery indicator reads "fully charged (97%). If I have the power cord plugged into the computer (and the wall), it boots right away. Without the power cord, the "power indicator light" flashes once, the screen brightens to a lighter shade of gray, then it just shuts down.
I'm thinking I need to replace the battery but I thought it best to check with the experts first...................☺
Thanks!!
ETA..........I just saw the post about power cord failure. My power cord is one of those affected and I will be filling out the request for a replacement. Unfortunately my serial number is apparently located inside the battery compartment. I'm wondering if my cord has overheated and caused this boot problem with my computer.

Hello, @jksweeney
Welcome to the HP Forums.
I see that your having an issue with the power and your notebook. That you've applied to have the power cord replaced as it was part of the recall.
Please let me know when that has been taken care of if the issue remains. I will remain subscribe to this thread, so that I will be notified if you post again.
Thank you for posting on the HP Forums.

My lenovo e330 wont boot ubuntu or any other os on usb or external hd at startup

I tried to install linux/ubuntu off my external hard drive by rebooting on windows 8.1 e330. And it just turns blank after i select the drive to boot temporaily by pressing F12. I also tried to remove quick boot to diagnostics, checked legacy settings were made to run first and secure boot was disabled ithin bios. its a shame cause i cant clean install windows or any Linux OS. Any solutions would be greatly appreciated

You could use CCC to do a trimmed down clone and leave out most of the sub folders. Do a 2nd clone to have a full working copy.
Carbon Copy Cloner 3.4.2
Cloning as a Backup Strategy
My guess is one of your drives needs to be reinitialized. Only during format will the hidden partition blocks be tested, and of course a healthy set of partitions created, things that cannot be repaired normally - though Lion Recovery partition does have abilty to check the health of partition tables. And about the only reason I'd even buy Lion!
Check partition table health in Lion's Disk Utility

HELP ME!!!!!!!!!!!!!
Sorry i posted dis twice

Use one of the OTA .zip files and copy it to an external SD card. Then boot your a1 like your doing an update with the power button vol + button and it will find the update.zip file on the external SD card. I used the latest .zip file and then renamed it to update.zip 2643 US file I had to use my laptop to put the .zip file on my SD card because of course my A1 wasn't working after installing the ICS_OTA.

Wont Boot from External USB HD

Hi Guys,
So Im in the practice of having a 'repair drive'. Basically I format and install OSX on an external USB HD plus a few maintenance programs. I do this so I can run diagnostics/housekeeping/optimization without being booted into the drive.
Anyhow, I formatted and installed OSX using my old white MB. Everything worked fine, I even installed the combo update. I get to boot into it on my white MB but when I try to boot into it on my unibody 15" MBP it doesnt want to... so I dont know what gives!! TIA

Boot the "old white MB" from the external, and double-check the version of OSX on it. Make sure it's not earlier than the version that came with the MBP. Check the MBP's DVD, or plug it's serial number in here: http://www.appleserialnumberinfo.com/Desktop/index.php

Sun v40z wont boot from external DVD/RW drive

Hello folks, I am banging my head on the wall with a Sun v40z that will not boot from an external dvd drive. I want to install Win2k3 Server on it. Any ideas.

The v40z is an x86 platform,and thus has a BIOS controlling the boot order and boot devices. You'll have to attach a VGA display and keyboard, power on the system, then hit F2 or F10 to enter Setup (it should say what magic key it is at startup time, just after the SUN logo splash screen comes up).
Enter the BIOS, and go to the menu for boot devices, making sure you select CD-ROM as a boot device before your regular boot disks or network boot devices. Then Save and Exit, restart the system, and it should see and use the CD for the boot device.
A caveat is that some early revisions of the BIOS's, especially ones on early x86 platforms like the v40z, will not recognize an external device as a boot device. You may have to download the latest BIOS, install it (uses a floppy, IIRC!), set the correct BIOS options again (they get wiped out when the BIOS is reinstalled), and then try the external CD boot again.
If this fails, you would be forced to install and internal CD device. This is not difficult, but is obviously more hassle than an external device.
Good luck!

Macbook Pro - Applications wont start without External Display

Hi all,
Apologies if this question has already been answered, but I have spent a lot of time Googling to no avail...
I have an early 2011 15" MBP with the following spec:
Model Name:          MacBook Pro
Model Identifier:          MacBookPro8,2
Processor Name:          Intel Core i7
Processor Speed:          2 GHz
Number of Processors:          1
Total Number of Cores:          4
L2 Cache (per Core):          256 KB
L3 Cache:          6 MB
Memory:          8 GB
Boot ROM Version:          MBP81.0047.B24
SMC Version (system):          1.69f1
AMD Radeon HD 6490M / Intel HD Graphics 3000
Snow Leopard Mac OS X 10.6.8
I normally use the MBP with a 27" Cinema Display connected (mini display port/thunderbolt connector) and the clamshell shut. All is fine.
However, if I remove the external monitor and want to use the MBP with just its own display, some applications will not start. They bounce int he dock for a while and then hang, and need to be forcibly killed. Not all applications behave this way, but so far I have experienced this with Aperture 3.2, Omnigraffle, Parallels, Pixelmator.
Does anyonw have a clue whats going on and how to fix?
Thanks

Hi Grant & Bob
Thanks for your responses.
The adaptor has been removed from the Mac, and I have tried all the obvious solutions (like using detect displays), but to no avail.
I will try and investigate some other scenarious (like using a different external display) and see what happens.
Thanks

Z77A-GD65 Wont Boot Without Clearing CMOS. Gets Error 32.

Hi!
I just switched GPU from 2x 7950 to 980.
I cleared drivers etc etc and was powering down my pc for the replacement. took out the cards and put in the 980.
When i later was trying to boot, i got debug error 32, which is early cpu initialization. So i checked all the cables and tried again. Same thing.
Took everything out and reinserted it again. Same error. even tried the to take out each ram to see. Still nothing.
I later cleared cmos and the computer booted. but then when i restart i doesnt boot until power everything down and clear cmos again.
Do you guys have any idea?
My specs are
Z77A-GD65
2500k CPU (Now after clearing CMOS at stock speed)
Corsair Vengance 2x4GB RAM
850W Bronze psu

Tryreplacing battery. Also could try to run it with single Ram stick and outside of the case.
I Couldn't wait so i went to town and bought me a battery, didn't change anything.
I've tried running a single RAM in each slot, just to try. no change there. Still error 32.
I've also test it outside the case now and still no difference.
Otherwise i've noticed i can boot if i press the reset button exact when debug code 55 shows. It's really weird. doing this way all bios settings are still there and i can test my pc with OC. I've played Dying Light on it this way with no problem at all. except this annoying code 32 who reappers everytime i restart my computer and hinders it to boot...
EDIT: Also sometimes (very rare), it starts at first boot.

Computer wont boot after long power down z77a-g45

Hi experts !
I think i need some help. I own a z77-g45, bios 2.9 + Core I5 3570K +SSD 120 Go intel + ati 7950.
I received this MB one week ago. Since, i try to make it work, no trying OC.
I began with Win8. Installations seemed fine, but after some time letting computer power down, i alwas found myself facing OS unable to boot, even when using older restoration point.
So i decide to go with win7 64 bits.
Once again, all looked like running fine, till a long power down, after that, OS refused to boot, locked on screen with colored windows logo.
I can boot in safe mode. But still couldnt find a faulty service with msconfig a dichotomic way. Os went back during the process..
What i noticed, is that after a long power down, it seems to happen something in the Bios : when the computer starts, it shuts down after one second, and then restarts again. Like if some settings were changed automatically by the motherboard. But I didn't see what the changes are.
Does that inspire someone ?
Thanks
Nicolas

I saw a similar post, where the guy changed the on board lithium battery.
I did the same, and now everything looks fine.
I also did a dual boot install : w7 x64 and w8 x64. That allows me to have access to a boot menu with the ability to easily start w8 in safe mode if needed. I noticed it can help, cause sometimes, the integrated GPU (HD4000) has some side effects.

Sounds like you will need to take it in for repair. If resetting the PMU like Apple had you do didn't work, you may have a power supply and/or logic board problem.
Also, if you don't have AppleCare yet, I would suggest buying it before your one year warranty is up if you plan on keeping the computer for awhile.

Imac wont boot of external devices

Hi,
This is a very strange problem.
I want to reinstall my windows partition and install windows again for bootcamp but cannot do so because the computer does not think that the bootable device is there, it does not like windows disks but happily accepts mac os x disks to boot from.
I am using A external dvd rom to boot the windows disk from and it does not come up when you boot up the computer and you hit the alt key when it boots, i have also tried to install windows from a external hdd that does not come up either in the boot menu ( i know it is bootable because i booted it from a PC)
Another thing I have tried is installing rEFIt and that does not pick it up.
The OS once booted into leopard finds the drive fine.
I have reset the DRAM thing and no luck.
I am seriously at my wits end with this.
Can some one help with this, it would be very much appreciated.

Just an idea for you. There is an entire Apple Discussion forum dedicated to Boot Camp and Windows.
Whereas, not everyone here with an Intel iMac has installed, tried to install or has experience with BC & Windows, everyone there has or at least has an interest. You may attract help more quickly there.
The Forums are at the bottom of the main Apple Discussions page under Windows Compatible Technology. Here is a link;

Panic (cpu 0 caller 0xffffff800ec59301) - BOOT from External SSD Samsung

Since few days I'm experimenting the boot of my iMac 27 i7 from external 500GB Samsung SSD series 840.
First test with SSD installed on the 2,5" Seagate GoFlex Thunderbolt without external power suffered by some frezing probably due to low current from TB.
Then I put the SSD in a 3,5" eSata enclosure with its own power supply and connect it to TB trough Sonnet Express Card Pro adapter and Sonnet eSata card.
Happy with the speed of boot and of the read and write to the SSD but expereincing some problems.
Few times the iMac does not boot . it remains on the gray screen with the rotating weel.
Once instead of the Apple in the middle of the gray screen I had in Gray something like the noparking signe (circle with a diagonal diameter line) and no boot.
Last time this panic printout, and no boot.
then the iMac could be restart without any problem.
Checked and repaired the SSD: no problem.
I cannot understand what is going on. I connect these with the boot from the external SSD and the complicated chain TB-SonnetAdapter-Card-eSata..
Or there is something more ?
Am I running any risk ?
I still have all my OS system and data on my internal HDD (which I keep every day in sync with the external SSD): this toghetehr with backups and TM should limit my risk.

Thanks Topher Kessler.
It was the enclosure (a Maxxtro 3,5" which negotiated only at 1,5 Gigabit).
I used for some time a Wiebetech 2,5" with 2 FW800 and the eSata (which negotiated 3 Gigabit) and now since yesterday the SSD works in a Value series 2.5" PATA/SATA HDD to eSATA/USB2.0 (from Great Britain eBay).
With both the 2.5" enclosures the system is stable.
The strange about the Value series is that the specs are for SATA II and transfer rates to 3 Gigabits while my system reports 6 Gigabit.
