Spontane power fallout

Have a Satellite SA20-S103 for about 2 years now. Works great but since a couple of days it shuts down instantly like no power is left in the computer. Computer is mostly connected to the main power and not on battery.
Any thoughts what this might be and how to fix this problem.

Hi Lanucia,
maybe the CPU is overheating, so the notebook powers off to prevent it from damage. You shoud check the cooling system whether there is any dust behind the grid. And have a look at the temperature of the mashine when it shuts down.
Bye

  • KT4AV - Spontaneous Power Down

    Hi There,
    I recently bought a new KT4AV with a XP2400 for my parents, popped it into the case and tried to install WinXP. XP installed no problem, but then I found the pc would just switch off of its own accord. I checked all the usual things, cpu seated correctly, fan fitted correctly, RAM ok, etc... Then came over here and read the first topic regarding Q-Tec psu's... Yep, it has a Q-Tec.
    The psu in the machine is the 400w dual fan model, which from reading all of the posts on this forum, sounds as if it is this which might be causing my problems... I just wanted to know whether others thought this was the root of my problem, before I go out and buy a new one.
    If the forum thinks that it is the psu, how do you guys rate the following models:
    Thermaltake Silent 420W ATX PSU Dual Fan - Manufacturer Code: W0008RE
    FSP (Sparkle Power) 350W ATX Passive PFC - Manufacturer Code: FSP350-60PN
    They are both fairly similar in price, and both appear to offer the recommended amp ratings and combined wattage... but other opinions are welcome.
    FYI, the set-up is as follows:
    XP2400,
    256 PC2700 DDR RAM,
    GeForce4 MX440,
    Diamond Supra Express 56k modem,
    Seagate 5400 rpm drive (I forget which one...)
    floppy,
    Lite-on 16x CD-RW,
    and er, thats it... of course I am using the on-board sound and ethernet, although I am planning on disabling the ethernet port once I deliver the pc to my folks as they don't have broadband....
    I originally thought that the 400w psu would have been more than enough...
    Your thoughts and recommendations most welcome!
    Regards,
    Flak

    Hi, Wonkanoby, Bas, et al,
    Ok, I have a couple of figures (mainly of different psu's, please recommend one) for ya....
    Antec Truepower 330
    +5v +12v +3.3v
    30A  17A   28A
    5+3.3=12 combined= 10W
    Antec SL450
    +5v +12v +3.3v
    40A  20A   28A
    5+3.3=240W, 5+3.3+12=380W
    Hiper 350 (Never heard of 'em, but the following from http://www.hiper-pc.com/static/products.html and are apparantly max loadings...)
    +5v +12v +3.3v
    35A  15A  28A
    5+3.3=175W, 5+3.3+12=330W
    And finally Hiper 420
    +5v +12v +3.3v
    28A  16A  48A 5+3.3=210, 5+3.3+12=400W
    Those last two are fairly cheap (around the same price as the crappy Q-Tec I bought originally. I do think that the last 3.3v is a typo, tho.... 48A?!!
    I would appreciate your recommendations on these psu's (I won't sue if they are pants!) as you obviosuly have quite a bit more experience with MSI boards than I ;o)
    How do these comapre to the Enermax 365?
    I have an Enermax 365 in my rig, I am about to try it in the poorly pc, but are any of those psu's signifcantly better than the Enermax? If they are, I might use this opportunity to upgrade mine.... and give my folks my old Enermax, bearing in mind that my folks don't do much other than check e-mail, play Solitaire and my old man occasionally has a blast on NFS5.....
    TIA, guys.... very good forum this!
    fM
    to add another couple of psu's... thought that whilst I was at it, I might as well ask for the world...;o)

  • Spontaneous power downs

    I just bought this tablet a couple weeks ago and it was working great. Then all of a sudden Thursday night about 20 minutes after I had just used it, it wouldn't power on though the battery was at 100%. I plugged it in and it showed the icon for battery charging with lightning bolt then it showed a battery icon with a "?" in it. But I pressed the power button and it came on. So I unplugged it and played with it for a little then shut it back down. When I tried to power it back on later, it wouldn't come on until I again plugged it in. It has gotten progressively worse as now it seems that if I even move the tablet it will just black out. Even in the middle of powering up the screen will black out.  All in less than two days???? Is there a way to fix this?

    Thanks for taking time to check the version and offer these specifics. Are you using the original charger that came with the device? Please test the charging function while in Safe Mode to see if performance improves as this will stop corrupted apps temporarily: http://www.verizonwireless.com/support/knowledge-base-122285/

  • Phone turns off, power cycles & drains battery

    My Curve 8530 has been turning off spontaneously power cycling then the Blackberry download screen comes on.  It will then fully load and when it powers back on the battery will be completely drained.  It will do this in the middle of phone calls, texting and browsing.
    Any ideas how to fix this?

    I had the same problem using MetroPCS blackberry curve 8530, I messed around with the network settings on my phone for hours until i figured out that it managed to stay on when i unchecked the mobil network, which disables the radio signal on the phone. Then I started shutting off every other wireless conections like gps, data, roaming, ect... Then i turned back on the mobil network and it seems to be a fix but you loose out on the usefullnes of the phone..

  • System powers off when on battery (battery at 40%)

    Without warning, when running on battery, my MBP will spontaneously power off. No sleep, no warnings, nothing. I can then power it back on, and it will run on battery long enough to come up, and let me start a few applications, then it seems to drop into immediate sleep mode without warning. This didn't happen in the past, but I'm uncertain when the behavior started. Has anyone else had this issue?
    Also, in system.log, I see this odd message:
    kernel[0]: Previous Sleep Cause: 2
    Not sure if it is related or not.

    Welcome to the Forums!
    Have you properly calibrated your battery recently?
    That enables the OS to determine time to charge and time to discharge, and thus provide you with a low power warning.
    However, it may also be a problem with the battery itself. There are known issues with some MBP batteries (due to manufacturing defects by Sony), which resulted in Apple extending the battery warranty for Core Duo machines to two years. You have a C2D, but there have been plenty of reports of battery problems with them as well.
    You can check your battery health in System Profiler (Apple menu > About this Mac > More Info), click on Power. If your Full Charge Capacity is less than 4400 mAh (which is 80% of the FCC of a new 15" MBP battery), and your cycle count is less than 300, your battery is failing prematurely. If that's the case, contact AppleCare or visit an Apple Store for a (free) replacement.
    Hope this helps...

  • Several Excite AT300 Issues

    Hello all, I recently purchased an Excite AT300 (16GB) model and have experienced some issues so far.
    1. The issue that I experienced today was the tablet kept powering down by itself. The battery was at about 26% and when I would power on the device, it would boot up, and power down almost immediately. At first I thought it would be some kind of power setting where if the battery falls below a certain % it will power down, so I checked the settings and there was nothing similar to that enabled. I proceeded to connect the tablet into the power supply and I no longer had this issue, because it was charging. This will become a great inconvenience if the device will power down at a certain battery %. 
    2. The other problem I have been having is with the SD Card. I recently purchased an SD Card from Amazon (SanDisk) and tried it out on the tablet. The device recognizes the card, but I am unable to copy stuff to the card. At first I figured that maybe the card wasn't formatted, so I put it into my pc and formatted it (Fat 32). I tried again and still the same problem with the tablet. My pc reads/writes from the SD Card just fine, so now I'm thinking that maybe the card isn't compatible with the tablet. Is there a list of compatible SD Cards with the Excite AT300 (16GB)? I downloaded two programs from the droid market to try and help me troubleshoot, and so far here are my results:
    SD Tools: App will not read/write to the card. It doesn't give me any read/write speeds and tells me that there was an error reading the card. Maybe the app isn't compatible with tablets.
    Astro: When i click on the sd card, it tells me that no directory exists, and asks me if i would like to create one. When i click on yes, it tells me there was an error writing to the card. When i try to copy files to the card (using the tablet) it tells me that i do not have permissions (denied).
    Has anybody else had these issues? 

    I've been using an AT305-T32 for about a week now. I have not seen an issue like your spontaneous power-down. I did, however, get up one morning to find it showing the boot animation--indeed, my wife said it had been showing it for a long time. When I force-reset it and got it back booted the battery usage graph made it look like it had been stuck there for several hours. Go figure. I have not seen it before or since.
    As to your second problem, I saw exactly this problem when trying an SD card in my wife's (then) new Galaxy Tab 7.0 Plus. After some research, I found that there was some design change in Android between Gingerbread (v. 2.3) and Honeycomb (v. 3.0) that changed how Android mounts removable memory like this. Don't recall all the details, but this is an Android thing. With some googling you can probably find the story I can't recall.
    What I found then and just re-confirmed on the Excite is that the native File Manager (Samsung in that case or Toshiba in the case of the Excite) is somehow smart enough or secure enough or something to work with the SD memory. (Not sure why the file manager apps can't or won't work the same way.) I just used the Toshiba File Manager to copy a file both to and from the SD card.

  • My Centro's touchscreen powers on by it'self at random draining the battery. Anyone know what can cause this. Verizon replaced my first Centro and the replacement does it also.

    null
    Post relates to: Centro (Verizon)

    I just found a solution and I've been working on this problem off and on for a long time. I never use my centro for email or Internet, yet it would spontaneously power down and restart, it might hang up, and it always drained power within a few hours.
    On another site, someone asked the question -- was this my first Palm or did I have one previously? Once that question was asked, I was reminded that I'd had previous Palm units, each containing different applications. So, I went to apps (home button then select applications from top left screen then select Delete). From there I was able to scroll down and verify what applications I'd had on my two prior Zires. I deleted functions that didn't come with the Palm Centro (a couple of third-party apps I no longer used, Expense DB, File Info and others). I also followed the solutions posted by others to turn select IR to Cradle, unchecked automatically select SMS messages (phone button - Options - Preferences - Connection - Edit - then select Cradle/Cable). My Centro had Network locked, so I couldn't do anything about that. I also went to VoiceDial from Main Menu - Settings - Choice Lists and unchecked each and every category). Then I performed a soft reset, re-synced and my battery (after 22 hours shows power at 96%. I'm thrilled. I just hope the good news continues. Good luck with your unit. 

  • M115 S3094 Popping/Static sound

    It seems that the sound is bad within the sound card, because I tried using a headset and it is still staticly, so it's not the laptop's speaker fault. 
    I tried updating sound driver, didn't help.
    I've read that flashing a new BIOS work, but I got a "0251: System CMOS checksum is bad" after the update so I had to restore to old BIOS.
    What else can I do? It is getting really annoying.
    Thanks

    Is this the driver you used?

  • MacBook shuts down spontaneously when on battery power

    My 2.0GHz MacBook has started shutting down spontaneously after half an hour or so of waking from sleep. After it shuts down, when I try to reboot it it shuts down straight away after the boot sound.
    Plugging the power cable in seems to allow me to boot, but it has also shut down randomly a couple of times whilst plugged in.
    Is this enough of a problem to get an entire machine replacement? I also have the stain issue (early signs of unremovable stains after only two weeks with the laptop), the moo issue, casing around the screen that is loose and at least ten keys that sit on the keyboard at an angle with one that was broken from the day I opened it (the "." key no less).
    Will I be able to get a replacement unit if I go to an Apple Store genius bar? I'm thinking either London, or Bluewater. I only ask because I have a conference that I need to report from in the next couple of weeks and can't afford to:
    a) wait for repairs if I send it off to Apple
    b) trust Apple to fix all the issues I have with the machine.
    I want a complete replacement, that's the only way I have a guarantee this problem won't come back in the middle of an interview recording.
    Thanks in advance for your help,
    Conrad

    What do you mean with "shutdown"? If it powers off all of a sudden, without kernel panics or going through the OS shutdown procedure, then it must be somehow related to the hardware.
    I had a similar behaviour (random power offs and inability to restart my MB for a while) after installing two new RAM modules. I noticed that putting back the original modules solved it so I inserted the new modules paying more care and eventually everything started working properly.
    Good luck...

  • Spontaneous Shut-off problem (power supply?)

    Hi-- I have a first generation G5 iMac.
    Last year, there was about a week in which it would spontaneously shut off. I read there were possibly some power supply issues with the early units, so I took it in to an Apple Store hoping they would diagnose such a problem and fix it; they ran it for a couple hours, said there were no problems, and sent me home. Over the last month, it has started happening again, and has happened at least seven times. I do regular backups and I've been lucky, but I know one of these days it's going to happen while I'm doing something important. I wouldn't mind taking it back to the Apple Store, but it's not an easy trek, and it happens so unpredictably that I think the odds of getting it to do it at an appointed time is slim, in which case I'm afraid they're just going to send me home again.
    Just wanted to know if anyone else has dealt with such a problem, what the fix was, and how I might convince the tech guys to delve a little deeper even when they don't actually witness the event.
    Thanks,
    dave

    Miriam--
    Dave, if, in fact,as Charlie suggests, the cause of
    your shutdowns is a variable power supply, it should
    easily be cured by the addition of a Universal Power
    Supply
    While an excellent idea (I wouldn't have a computer without connecting it to a UPS any more), a UPS won't necessarily solve the problem of the unexpected shutdowns. My iMac was on a UPS and it still would shut down.
    There are two kinds of UPSs. The most common is a battery backup. Most of the time, the computer is actually getting power from the mains. If the UPS detects a failure of the mains, it'll switch to providing the computer with battery power. But there will be a very small fraction of a second where there will be not power at all supplied to the computer. If the computer's power supply is healthy, it should be able to bridge that tiny interruption until it starts getting power from the UPS. But if it's not healthy enough, the computer will shut down.
    The second kind of UPS is what you are describing, where the UPS provides power to the computer at all times. These aren't as common, though, and are more expensive. I'm not sure if APC even sells this kind. At least, I couldn't find any at their web site that I could be sure were this kind.
    When I had the shutdown problems with my iMac, I initially thought it might be a problem with the UPS, since the iMac would shut off if the power was interrupted long enough for the UPS to notice. I could easily test it by just pulling the plug going to the UPS. Earlier, I had been able to do that without problems in order to test a script I was writing to shut down the computer in case the of a power failure (for some reason, the software built into OS X to do this wasn't working right).
    But when I was having the shutdowns, the iMac would shut off right away as soon as I pulled the plug on the UPS. Luckily, I was able to test my UPS at work on another computer and try a UPS from work on my computer and rule out the UPS. Now that my power supply unit has been replaced, the iMac will once again survive the switch from the mains to the UPS's battery.

  • Spontaneous HD power failure

    Having some odd behaviour on my MP 5.1 12 core. Been having some finder, dock and UI server hangs, an FW Drobo (external raid device) also hung spontaneously.
    However just recently I had one of the 5 internal HDs vanish completely from the system. I got a notification that the drive had been unmounted improperly, checked DU and system info to find no sign of the physical drive. It was as if the power had been cut. Rebooted, still gone. So I assumed it was a spontaneous drive failure.
    Upshot is I tried a reboot into recovery mode and into DU, and there was the drive! Did a repair (no issues) and rebooted and it was as if nothing had happened. SMART reporter says all driver are good no issues. I'll clone the drive and replace it just in case but I'm concerned it may be a motherboard issue.
    Is this the beginning of the end of my 12 Core, or could it just be a system issue?
    I'm currently running Mavericks and have been testing Yosemite on another machine. Wondering whether to try a fresh system on a new drive, but that's a big job.

    force a shutdown and the directory and unsaved changes are lost. \
    Zeroing a drive from end to end would be first step, along with just plain replace it and restore from a KNOWN GOOD backup set from before when all this started.
    I had a bad DIMM for 3 days, it took me over a month until finally I did a clean install and avoided questionable backups, even after using Disk Warrior and everything else at hand.
    Took over a month with a funky USB cable - Apple's, and Apple engineer wanted to blame my non apple mouse and keyboard. A couple years later, same system, and could not zap pram with the apple kb. USB can do funny things. And in this set of issue, drive bay #3 was not working.
    Well all of that is in the past, each was hard to figure out.
    Disk Utility does not scan or know the health of all the drive sectors. SoftRAID does check sectors in background and in reporting errors.

  • IPad won't power off and tends to spontaneously reboot

    When I try to power off my iPad (pressing the sleep button then sliding the "slide to power off" slider), it displays the wait progress indicator, goes black just briefly, then the silver Apple boot up logo appears as the device reboots which results in the device remaining on.
    Worse yet, the device tends to frequently spontaneously reboot, often when the home screen is displayed and not performing any user operation.
    I really don't want to restore the iPad as this results in metadata loss for thousands of audio files (Apple really needs to address this inadequacy and provide a Time Machine back up option for us users who choose to manually manage files on iOS). Is a device restore my only recourse?

    It sounds like something is crashing your iPad resulting in this spontaneous reboot. Without knowing what you're running or if you've done anything unusual to your iPad, it's hard to say. There is a remote possibility that it's hardware related, but I would go the software route first. The only way to find the culprit, without completely restoring (which I would actually recommend here) is to one by one delete program apps and see if the problem ceases.
    If you completely restore and the problem disappears, then it was software related. If you backed up your iPad before restoring, you should be able to restore it from the backup thus retaining any data you had stored previously. Of course, this would also reinstall the offending app that was causing this behavior in the first place, but at least you'd know it is software and not hardware related which obviates a visit to your local Apple Store.

  • Kernel Power - Event ID 41 - Task Category 63 (spontaneous improper shutdowns and reboots)

    I have been having consistent power offs/reboots lately, and im at my wits end about how to fix them.
    It always seems to happen when im playing a high end game (Guild Wars 2, Mirrors Edge, etc.). 
    I havent experienced it while just browsing or doing basic work, or while playing lower intensity games that hog less resources.
    The computer screen goes black, it reboots and i get the "windows has had an improper shutdown" kind of message.
    Usually after playing the game for an hour at the least, though its happened 2-3 hours into the game as well.
    I checked temps, and they are all normal,
    Ive also attempted updating drivers, and downgrading from any beta drivers i was using, and none of that seemed to affect it.
    I checked event viewer,
    And right before this shutdown i get the critical error "Kernel-Power" "Event ID 41" Task Category 63"

    If anyone has any suggestions as to what could be going wrong, or things to check it would be greatly appreciated.
    Ive looked around at others solutions and tried whats helped others and it hasnt done much so far.
    it seems like this is a very broad problem, with no unspecific fix in most cases.

    Hi,
    This scenario usually indicates a problem with the hardware. Or, the driver can cause this problem. To help isolate the problem, check the following items: 
    1. Overclocking: Disable overclocking to see whether the issue occurs when the system is run at the correct speed.
    2. Check the memory: Verify the memory by using a memory checker. Verify that each memory chip is
    the same speed and that it is configured correctly in the system.
    3. Power supply: Make sure that the power supply has enough wattage to appropriately handle the
    installed devices. If you added memory, installed a newer processor, installed additional drives, or added external devices, such devices can require more energy than the current power supply can provide consistently.
    4. Overheating: Check whether the system is overheating by examining the internal temperature of
    the hardware.
    5. Defaults: Use system defaults, and run the system. 
    If you see that the computer generates a Stop error that contains a BugcheckCode value that is not reported in an event ID 41, change the restart behavior for the computer. To do this, follow these steps:
    1. Right-click My Computer, and then click Properties.
    2. Click Advanced system settings.
    3. Click the Advanced tab.
    4. In the Startup and Recovery section, click Settings.
    5. Click to clear the Automatically restart check box.

  • Mac Pro 2,1 Spontaneous Restart with No Boot - Power Supply PSU Problem?

    One day I was working away on my Mac Pro 2,1 Quad Core 3.0 (2007) with 8 gb ram running Lion and it just shut itself off like someone pulled the power cord (but no one did of course). Then it attempted to restart, but wouldn't boot. Basically I haven't been able to use it since as I can't get the computer to stay on for any length of time.
    I'm thinking its either the power supply or the, oh no, logic board.
    Symptoms have been like this so far:
    Initially I would get a chime and a boot start but then I would find the computer would shut itself off somewhere in the process and try to restart. Usually the next time I would get no chime and a horrible repeated clicking of my optical drive with a rythmic fan whirring up and down on the original ATI x1900 xt graphics card. I would have to manually power off with the power button to make it stop. Sometimes it would try to restart again anyway. The only way I could get a chime again was to unplug and wait (longer the better). But even if i got a chime and a start of a boot, invariably the computer would turn off again.
    I couldn't boot from another source, I couldn't run apple hardware test, I couldn't run diagnostic,... it just wouldn't stay on to do it.
    I hauled my mac pro (out of warranty) to the apple store genius bar and the problem presented itself, continuously. The gent was able to get fsck to work long enough to determine my hard drive was ok and said it was one of three things - the power supply, the graphics card, or the logic board. He said because the comp powered on and then shut off, and because there was intermittent chiming, he didn't think it was the power supply. He thought it was the graphics card and said I could leave my Mac for 10 days and they could take a looksy, or I could just install a new graphics card on my own.
    I chose the latter, bought a ATI Radeon 5770 from the apple online store for $275 and installed it.
    Problem persists.Exactly the same as before. Got initial chime, then next time no chime, optical drives clicking and graphics card fan whirring up and down rhythmically.
    I had a touch of time to disconnect everything and I get a chime consistently now when I have my boot drive, graphics card, 4 gb ram, and monitor attached. (As well as wireless mouse, keyboard, trackpad). I even got to logon once only to have a prompt shut off and restart attempt. also I verified it was at least one optical drive clicking (when I removed them both) during these boot attempts.
    The improvement in chiming seemed to be when I unseated one ram riser ( I have to with 2 x 2g ram modules each).
    I also checked the diagnostic leds on the logic board and all was as it should be... says I got trickle power and rail power etc.
    Is there anything else I can do to determine what's wrong? What do you guys think is wrong? Could it be bad RAM? Power Supply? Logic Board?
    All your help is massively appreciated in advance!

    Well I ran as many tests as I could with no definitive results to the point I would have to start buying replacement parts and testing that way. I opted to take it back to the apple store and they said it's (dun dun dun dunnnnn) the logic board.

  • Spontaneous and instant shutdowns, regardless of power source

    My MBP has begun to shut down with no warning, and instantaneously. It's nothing to do with battery power because it does this when a) fully charged, and b) plugged in to the power adaptor. I've reset power management, but it has made no difference.
    The only thing that I've been able to deduce is that it seems to do it soon after waking from sleep: when, for example, I have shut the lid to move the computer from one room to another at home. Sometimes it's dead on arrival (ie, when I reopen the lid). More often it wakes up and works normally for two or three minutes, then the screen goes black and it has instantly shut down, as if the power supply had been pulled. Once it has passed this sleeping/moving disturbance it seems generally to work perfectly all day.
    Once or twice I've noticed abnormal fan activity just before shut down; but just as often it shuts down with no fan activity.
    After the shut down I press the power button and it boots up immediately, as is nothing had happened.
    Could this be a motherboard fault? I spilt coffee on the keyboard about nine months ago, and had the keyboard and top case replaced under an insurance claim. Could there perhaps be some invisible damage to a motherboard element?
    Any suggestions gratefully received. Thanks

    Ok - well this is interesting. My MBP shutdown again - i was closing a window in Firefox - pressing Command-W. It occurs exactly as i pressed the left-side command key.
    So when i powered up again, i firmly pressed the left Command key again, and bam, it shuts down again. I repeated this 4 times to prove to myself that it was definitely pushing hard on the Command key that shut my computer down.
    Did some more searching and people seemed to have success with changing the Energy Saver settings back to "Normal". I've done this, and now i can safely push the command key without shut down.
    Its only been about 2 hours, so i can't at all say its fixed, but worthy of an experiment if you're having this issue. It seems hardware related, but could just be as simple as changing the Energy Saver settings... i hope.
