Satellite L350-20G powers down during boot up

My Satellite L350-20G starts to boot up and after 10 seconds powers off.
Also it refuses to charge.
We have exchanged fully charged battery packs with an identical model and same problem.

I have the same problem with my Toshiba L series laptop
I check the output DC voltage of the battery, it reads 10.8 Volts, 4000mAh Model No. PA35346-1BA5
The DC output voltage of the AC/DC adapter, reads 19 volts at 3,95 amperes Model ADP-75SB BB
i think the adapter output voltage is not compatible with voltage requirement of battery of the laptop.
Please check your battery and ac/dc adapter ratings which affects the battery life, maybe there is an over voltage limit switch installed on the motherboard which keeps the unit turning off whenever the ac/dc adapter is connected due to higher voltage rating.
I think the allowable output voltage requirement of the AC/DC adapter should only be up to 12Volts DC to minimize the heat produced during charging period.

HP Pavilion a1730n shuts down during boot

Have been using the Desktop Pavilion a1730n for several months after upgrading to Windows 7 Pro 64 bit. Without any warning signs, now the CPU shuts down during boot up. When I shut the main power supply switch off and then turn it back on, then switch the CPU on with the front on/off button it gets 15-20 seconds into the bootup and then powers off spontaneously and completely.
If I try to start it immediately again without turning the main power supply switch off then on and only depress the front on/off switch, it starts to boot but only gets about 10 seconds (varies) in to the boot process before in shuts down.
What could this be? the power supply? the mother board?
ANY ideas would be appreciated.

Hi , Sounds like the power supply , when a load is put on the supply it does not seem to be able to cope with the correct output . You can buy a new supply ( same watt output or better )eg; if you have a 400watt supply get 400watt or higher supply as replacment . Checkurtech

N200 shuts down during boot

Dear Lenovo,
I have a problem with my N200 laptop. Notebook shuts down during boot. Sometimes it is immediately after "Lenovo screen", sometimes it is when Vista logo appears. I found out that this is always when notebook is "cold". It does't matter if I want to switch on my notebook or if I want to restore it from hibernation or sleep mode. Next thing is that it always crashes when fan starts work at full tilt (I checked the fan but it is clear). When notebook starts correctly then it works without problems. Usually I have to switch it on about three times then it is OK. This problem takes about 2 weeks. I have my laptop about 7 month. Do you have any ideas how to solve this problem?
And another thing - I forget to send registration card to Lenovo and now I am afraid that I will be without warranty. Can I send it still now?
Thank you for answer and sorry for my English.
Gabi

Yes, problem with the video card sounds plausible! Any not so successful updates recently? It is sometimes to make a good uninstall, which is required to make a good install.
4in1 drivers should - esp. with W98 and ME - be installed while in SafeMode and with all autostarting programs disabled, for example Antivirus and utilities.
Else, since you have a damaged regedit, I would reinstall Windows. You might have done something for example an upgrade or new install the registry, not healthy, has made a note of. Some utilities also overwrite and change system files without good results.

I can only start my iBookG4 after deleting preferences. I have to go into single user mode to do so. If I don't go into single user mode, the computer shuts down during boot up. What might be the problem?

I do not have a startup disk. I did try fsck (based on what I learned from your reply-thank you). This failed (fsck); here is the message:
** Checking catalog file.
Invalid key length
(4, 8198)
** Volume check failed.
/dev/rdisk03 (hfs) EXITED WITH SIGNAL 8.
I am sure this is an easy fix; I just have no clue how.

MacBook Air shuts down during boot

My Macbook Air (OS X Yosemite - Early 2014) automatically shuts down during boot, with the screen flashes during the loading bar at 40% and then shuts down. I've tried to reboot many times but it wouldn't get past the 40% on the loading bar.
I've also tried the following but none worked:
The Apple Hardware Test shows that "There may be an issue with a memory module." (PPM002, PPM003, PPM004) - though I've checked that the reference code and the definition doesn't match, as "There may be an issue with a memory module." should be PPM001, and PPM002-PPM015 should be "There may be an issue with the onboard memory.". I've sent this message to Apple and they'd only provided the option to visit their retail store.
Also, the Recovery Mode isn't much help either. As do not have a backup of my HD, I'm not able to restore from Time Machine Backup.
So, I've tried to reinstall OS X Yosemite, but it says "Unavailable to install OS X". A website online says that you can resolve this issue by correcting the date through terminal, but the basic menu bar won't appear, in which I'm not able to access Terminal during the Recovery Mode.
Therefore, I've also tried the Disk Utility, which it shows it can't be repaired, with the following messages: Invalid Node Structure (4, 57963), and 2 messages regarding the Invalid Extent Entry (4, 47013) and (4, 40808). The Single User Mode with the command fsck -fy yields the same message.
Is there any other options then to visit the Apple Retail Store?

Invalid node structure
I'm pretty sure you need more then Disk Utility to repair the drive.

Computer sometimes shuts down during boot, help please.

Hey guys,
My specs:
2500K @ 4.5 GHz 1.37V (12 Hours P95 stable + 10 IBT passes)
MSI Z77A-GD65
8GB DDR3-1600 Corsair Vengeance (2x4GB)
EVGA GTX680 Superclocked
Crucial M4 SSD 128GB
WD 1TB Caviar Blue
Seasonic X-650 PSU
The PC is roughly 1 year old and I built it.
Problem is, and this has been ongoing since I built it, sometimes, when I turn on the PC, it will start booting and then power itself off, after that it turns itself back on and Windows 7 loads, exactly what happens when you apple new OC settings for example.
There is never more than 1 shutdown when this happens and it never happens when the PC is on and working, just during boot.
I ruled out heating issues, everything is well ventilated in my Corsair 650D case, all fans are working and the CPU temps are good (Using Zalman CNPS10X cooler)
I think we can also rule out any PSU issues since I recently tested my PC with P95 again after updating my BIOS for more than 12 hours and it was rock solid. I've also never had a shutdown during gaming since I got the PC.
My Overclock is raw, I have disabled, EuP 2013, C1E, EIST, Overspeed Protection, Intel C-State.
Is there any BIOS setting which could be causing this? I noticed that there's a setting under EuP 2013 called "Restore after AC Power Loss" and you can choose Power Off/Power On/Last State. But I think it only related to occasions where the PC gets shut down due to a power outage?
I am inclined to think that this issue is more related to a MB BIOS setting than to the PSU since I never had any stability issues with the PC during OC testing or when gaming.
Which leaves me with the Power outlet. I am using an outlet splitter and currently there are 7 products connected to 1 socket:
1. PC
2. Yamaha RXV-471 Receiver
3. Morel Sub-8 Subwoofer
4. PS3 (Off 99% of the time)
5. Internet Modem/Router
6. TV Box
7. 42" LED TV Screen
The only thing I can think of is that maybe when booting up, not enough power is provided to the PSU and it turns off?
I have 1 other clear outlet next to the one being used and I'm fairly certain they both go to the same place in the panel because they are adjacent.
I can also try to replace the power cord, however, I replaced it once and I do recall it was happening prior to replacing the cord several months ago.
Any suggestions? Thanks

That's normal, the memory you have is 1333 with an overclock profile of 1600. (XMP) The double cold boot has been an issue for ages on the z77a-gd65 although I thought it was corrected by the latest bios's.
Oh so true. When it is really cold in the morning, not always, at first start of the machine, I will get a double boot behavior on a Z68 G3. No big deal, as xmad stated, this double boot behavior has been a trait of Intel for a long time. Usually disable of EuP 2013 cures it, but the OC and particular frequency combinations play a part in it, and mysteriously, cold mornings once in awhile.

Vp6321 projector shuts down during boot

I have a vp6321 projector that has been working fine up untill yesterday. When I turn it on, it seems to boot as normal, but during the boot sequence (typically while counting down the boot screen) the lamp is shut off and both status indicator lamps blinks one before the projector shuts down. From the manual I see that this is caused by an internal error and that I should contact HP Support. Is there any way to fix this?
PS! I've been looking everywhere for somewhere to contact you without luck (I can't even find the product on the support site) - should it really be this hard to get hold of support?

I am having the same problem with two of four of my vp6320 projectors.
I tried changing both the color wheel and lamp with no success.
Customer support DOES NOT EXIST for this product anymore.
I am not certain that it is an over heating issue, in fact, I am not at all convinced of one ailment over another. Sometimes the projector will turn on fine then shut down after a few minutes (followed by twin blinking lights, 3 seconds apart). Other times the lamp will not fire and a broken lamp indicator is on. Next I'll try again and it will flicker like mad and kill itself after about a minute. Then a new set of failures different from the last error will occur. I have no idea what to think.

Km2m shuts down during boot after running via chipset driver install

Ive recently purchased a new computer with a km2m Combo mobo and am having trouble getting it properly configured and running.
I attempted to run the "One Touch Setup" on the drivers and utilities CD that was supplied with the system. Reeceived a message to first install the VIA Chipset drivers. I ran the chipset driver install and simply clicked NEXT on all the screens accepting the default options. The install appears to complete successfully and restarts the pc.
during restart the pc abruptly powers off!
I can reboot the system in safe mode.
I've run msconfig and disbabled everything and the system still powers of during a normal boot.
If I restore the registy (scanreg /restore) the system again boots properly.
What causes this anomaly and how do I resolve it? Is there some sort of hardware incompatibility? I'm stumped!!!
AMD XP 2400+ 266FSB
OS = Windows Me
PSU = +3.3/28a +5/40a +12/18a -12/1.0a -5/1.0a +5SB/3.0a
what other info is needed?

A30: Powering down during installation

I have a satallite a30 laptop and i have started to reinstall it, and it just powers down, i have to resart everything all over again, i am not getting any where with it,
I have checked for dust and build up, discharged the battery, long charged it etc and still nothing, please help.
Regards
Magi

Hi Magi,
I presume that you are trying to install your system from the recovery CD when the unit powers down.
This normally indicates that the restore process is having difficulty writing to your hard drive and as a result the unit powers off.
If you have access to a bootable CD with error checking utilities (such as Norton DiskDoctor or Ultimate Boot CD) then you can try scanning the hard drive for errors.
regards,

Powerbook G4 Powers Down during start up

Hi There,
I have a 15" Alum. Powerbook G4, 1.5 GHz, with 1.5 GB of RAM. I shut down my computer last week and the next time I went to turn it on, it shut down during start up.
I can hear the computer working, the chime plays and then i hear the system power down. I did this 3 or so times before it booted all the way up. I shut it down a few days later and the same result. This time it took a couple more times to start it up. Today I shut it down and it took 15 times to get it to boot.
It's like trying to get an old car to turn over, but it just doesn't want to!
I have it started now, and I keep it in sleep mode. I'm backing everything up, but does anyone have a suggestion as to what I should do?
Thanks,
Lucas
Powerbook G4 15 Mac OS X (10.4.5)

I would recommend to boot in safe mode.
1) Wait for the startup sound
2) Hold down shift for a while
You know you are in safe mode when the login window appears and above the user names there's a red text: Safe Mode.
Then restart. Safe mode does some HD checking/repairing so it takes a lot longer to boot up - that's normal, be patient.
On my Powerbook, whenever it crashes (not often) it won't start up at all unless I start it up first in safe mode.
Other than that, resetting the PRAM also often helps (reboot and hold down option-command-R-P, all 4 keys, wait for the boot jingle to ring a second time).

Time Capsule Shuts Down or Powers Down During or After Backup

Just started backing up my wife's MBP (Leopard) to our Time Capsule via Time Machine. Previously the Time Capsule had only been used as an Airport, and had never shut down by itself. Now, inexplicably, the Time Capsule powers itself down. If I stop backing up to it, it stays on. If I run Time Capsule, it powers down. Powers up again fine - unplug, wait 10 seconds, and it cycles to a green light. Then a few hours later, Time Capsule is discovered powered down. Its not the cats, not the dog - it seems to be whenever Time Machine runs.
Checked the firmware on the Time Capsule and upgraded it to the most current. Made no difference.
What is going on?

So this just started happening to my Gen 1 500GB Time Capsule as well. I came across these articles:
http://www.macgasm.net/2010/07/12/time-capsule-recalled/
http://www.guardian.co.uk/technology/blog/2010/jul/13/apple-time-capsule-failure -analysis
The second one claims that the shutdown is due to an "overheating fault in some of the electronics around the power supply." I am going to check the serial number on mine to see if it falls in the range for a recall-replacement (since I am way out of warranty).
Even if yours isn't in the recall range, is it possible it's damaged from prior overheating?

Macbook Pro shuts down during boot

Hi there,
Few days ago I spilled some beer on my 2 weeks old Macbook Pro... I immediately cleaned it, removed the battery and charger and left it to dry for 1.5 day.
After the drying period I tried to power up the machine, it did work but unfortutanely shut itself during the boot (the spinning wheel) and power button didn't respond again until I removed and re-connect my battery. Tried everything such as Nvram/Pram and SMC reset, single user thing, verbose mode, changing ram dimms but got nothing. It did eventually boot with hardware test but again got nothing as the test indicated that there weren't any problems.
It always shuts itself after "Checking catalog file" in the verbose mode.
(The machine shuts itself even when I try to boot it with os x installation disc so the only thing that I can reach is the hardware test.)
(To tell the truth I don't know if I succeeded creating a bootable installation disc as I did it under windows.. I'm hoping that I failed and that it can actually boot from dvd drive)
Did I just screwed my logic-board, if so how can I run all the tests.. Any suggestions?

Immediately disconnect all peripherals, power cord & remove the battery. Turn the computer over with the lid partly open and the hinge facing upward to let the liquid drain. Do not flop it over and lay it flat - you want to separate it from the moisture. Place paper or cloth towels under the machine to sop up the mess.
After the computer disgorges whatever you spilled on it, don't turn it on for 72 hours or longer. You want to computer to dry out completely before turning it on again.
Some users here swear by hairdryers. Blow drying the innards may bake whatever was in the liquid onto delicate computer components. Better to let the computer air dry.
Use plain tepid water to clean out the computer. If you spilled iced beverage more than likely this ice fried the hot motherboard.
Sugary, acidic or milky drinks will almost always cause problems later on as the residue starts slowly corroding the computer innards.
Swab down any sticky parts with distilled water or denatured alcohol.
If none of the above works, you will need to take the computer to a repair shop. Apple Care does not cover liquid or food damage. Believe me, they can tell. So the old "my computer stopped working" line is not going to work.
In order to not void your warranty any further, take it and let the staff clean it. It's worth it for a 2 week old computer. In the future, avoid eating and drinking while using your computer. Will avoid future heartache and expense.

IMAC powers down before boot up is complete

After a forced power down my iMAC won't boot again.
The machine simply powers off after the spinning gear on the gray start up screen spins for a few seconds.
I've tried booting in safe mode, doing a PRAM reset and inserting the Installer DVD but I don't even get to any of these steps and the machine turns off.
help!

Do the SMC reset at least 2X, sometimes it doesn't always work the first time. If you still don't have luck please restart in Safe Mode , this will clear some caches. If that doesn't work you may have a hardware issue and should then try running Apple Hardware TestHardware Test in Extended Mode. If you can run AHT in Extended Mode if it does not find errors after the first pass then run it again 2-3 more times, sometimes AHT doesn't find errors after the first or second pass.
If you still don't have any luck then your can try to boot from the Leopard Disc by holding down the C key when you hear the startup tone. This is a slow boot because loading from the DVD is time consuming. Then enter Disk Utility (Applications - Utilities - Disk Utility) and Repair Disk Permissions and also run Repair Disk. If the disk return errors continue to run RD at least another 2-3 more times until no errors come up. However your computer is old and the HD may have failed.

17" early 2006 iMac powers down during startup

I am running 10.5.2 on an early 2006 1.86GHz Intel Core Duo 17" iMac (white), 160GB HD, 8x Superdrive, 2x1GB RAM.
1MB L2 Cache (from memory), bus speed 667 MHz (also from memory).
Latest BootROM (forget which one), checked for updates about a week ago.
Am, or rather was. It died this afternoon. I came back to it after lunch and the hard disk was making a distinctive pattern of clicks - a slow 1 - 2 - 3, which sounded like regular clicks and releases of a button, and then a short burst, followed by the 1 - 2 - 3 etc. The noises themselves weren't unusual, sounding just like ordinary disk access sounds, it was just the regular pattern that was distinctive, and the fact that none of my open apps were responding. I had been copying some files to the computer over the network and the copy had errored out with only a few files left to copy. Over the next 30-45 minutes I managed to force quit all the apps (about 7mins per program), but still couldn't shut down or restart, and ended up holding down the power button to switch the machine off.
I gave it half and hour's rest and powered it up, but it got stuck after the apple logo and the circle of spinning bars appeared (they were both still there). The hard disk made the distinctive pattern of sounds again.
The next time I started it, I tried zapping the PRAM, but the machine got to the same stage before powering itself down. Trying to boot into Safe mode or from my Leopard install DVD or in Target Disk Mode also failed. Every time, the Apple logo and the spinning circle of bars appeared, then the machine shut off, I presume before it can do any of those tasks.
I have tried taking each of the RAM modules out - same result.
I am not sure whether the problem is the hard disk, or the logic board or power supply, or something else entirely. I have heard on another forum that some iMacs went out with faulty capacitors on the logic boards and that you can check on Apple's website to see if your serial number falls into that range, but I can't find the page (search terms were intel imac logic board faulty capacitors power supply serial number, and variations thereof).
Recently I have installed several freeware and shareware apps from magazine DVDs, and had particular problems with Intego Fileguard. It creates 'safes' to encrypt folders you specify, though when I asked it to put my emails, pictures, movies and music in four separate safes they all became corrupted immediately. In the case of the pictures and music I lost most of the files (nearly all recoverable from backups/original CDs, thankfully!).
Also, just yesterday the machine had crashed after a restart, reaching the same point as it does now, but this time it didn't power off. When I powered it down and gave it a rest, it started up normally.
This is my first dead Mac, and I'm realising what a traumatic experience it can be. Help will be much appreciated!

Welcome to the Apple Discussions!
I would reset the System Management Controler.

OS X Yosemite shuts down during boot (which is very slow)

Here is the situation. After upgrading to Yosemite I noticed my boot time slowed down, same thing happened with Mavericks so I didn't think anything of it, figured my 2011 Macbook Pro was just showing its age. Anyway last night the battery died. I go to plug it in and reboot it and it is taking a very long time to boot up, the little status bar got about half way across then it just shut down. I have tried resetting the PRAM and I have also tried running the disk repair utility in recovery mode, disk repair says the disk is unrepairable. I don't know what happened to cause this and if this has happened to anyone else. Any suggestions would be appreciated. I would like to avoid the cost of a new hard drive and or the time spent starting anew by wiping out this one but if that is what it comes down to then so be it. Anyway thank you for reading this long winded question and for any suggestions/help that is given.

Sounds like the hard drive is failing. Not that expensive to replace yourself.
