Sudden Power OFF - Tecra R840

I have a Tecra R840-S8410 that powers off immediately after I power it on. It also makes a noise similar to a camera flash when it powers off. Any ideas what may cause this? I've tried to google this problem but have not had much luck, any help would be greatly appreciated.

Sudden Power OFF - Satellite A110-195

Sudden Power OFF My Satellite A110-195 suddenly power off while using on A/C power, it happens many times a day after 1 to 1 and half hour use, the room temperature is 20 to 25 degree Celsius. Again I have to push the power button to switch on the laptop. Why its happing?

The classic cause of an uncommanded shutdown is overheating. The system shuts down to prevent damage. Had your power adapter failed, the system would continue to operate until the battery was exhausted and in that case you would get low power warnings before shutdown. If the system is under warranty, the best course of action would be to take it to a Premier (emphasis on Premier) Authorized Service Provider. If it is overheating, they will open it up, clean out the accumulated dust and dirt, remove and clean the processor heat sink and reapply thermal grease. If it's not under warranty, you can do much the same yourself - or at least as much as you are comfortable with. At the least you could blow out the air vents with a can of compressed air and see if the situation improves.

Suddenly power off screen came on

All of the sudden, the power off screen came up asking me to power off the phone. When I clicked cancel, it went back to the home screen and I pressed the home button, it kept taking the picture on the screen and went back to the sxreen asking me to power off the phone. Or just frequently comes up the power off screen. If I did power off the phone and turn the phone on, it will be fine for a few days and it happened again. This had started to happen a numbers of time since April.

Sudden Power Downs | Sudden Power Offs

We have just moved from one office to another office in the same small unit (rewired by professional A grade electricians).
We now have the following Mac Pro's suddenly switching off:
1/ Mac Pro QUAD 4 Core (3 months old, worked fine in old office) 10.5.2
2/ Mac Pro QUAD 8 Core (1 week old, worked fine in old office) 10.5.4
3/ Mac Pro DUAL 4 Core (1 year old, worked fine in old office) 10.5.3
Does anyone have ideas as to why this is?
Is it a system, OS X 10,.5.x issue?
Is it a hardware issue?
All (but the 8 core as it's too new to consider) have been fine till the move.
Or is it the electric's and the power draw on the system?
Mind you, shouldn't all the Macs go and not just these ones (together or separately)?
We have 12 other Mac's (Pro/G5/iMac/Mini, 10.4.11, + perriferals) on the power ring too.
I have read about MacBook Pro power issues but cannot find anything about Mac Pro's on the Discussions...
I think it's the wiring / electrics...am I correct?
Thanks,

I have a Mac Pro 8 Core and I've also had trouble with 3 seemingly random power downs. I noticed that an external HD on the same outlet was off (it does not turn back on when power is restored like my other HDs), which lead me to believe it was an electrical problem. The power never went completely off as far as I can tell, as the clocks still read correct time.
Until I can figure out and fix what is actually causing the shutdowns, I decided to buy a cheap battery backup which could help keep my computer up if I am just overloading the electrical system.
I bought the APC Back-UPS ES 350 Battery Backup/Surge Protector at circuit city for $30

Granted with as many computers as you are running, my quick fix is not as fitting a solution.

MSi GT70 - 0NE-276us Sudden Power Off/Will not Stay On

First and foremost, thank you for taking the time to read about my problem. No sob story, however this is my only computer and it was/is my work machine in the IT Administrative/Deskside Workplace. Any ideas are welcome.
I have an MSi GT70-0NE 276us Laptop. I bought it last year (Christmas). I was playing a game on Steam when suddenly the machine turned off. Using my troubleshooting experience, here is what I tried:
-Removing the battery and power supply from the machine and holding power button for 1 minute
-After testing with ONLY the battery inside the machine, pressing the power button makes a white flash and a shimmer of light sent to the keyboard, but doesnt actually turn on. It does this upon each keypress and does not skip a beat.
- I tried to connect the power supply directly into the laptop WITHOUT the battery connected, and it does the same thing. As for the battery indicator light, it does not stay on as it normally would when the power is connected to it.
NOTE: I have NEVER used my laptop WITHOUT the power cord connected; it is always attached since I know its a power hog.
- I have checked for any smells of burning/melting and there are none. The laptop was also not that hot when it cut off suddenly.
- Ive blown the mainboard/underside with compressed air and removed all of the dust
- Ive made sure the fan was clear and connected
- Ive reseated the RAM
- I have NOT tried another power brick; the one I received was refurbished.
- The LED on the power brick lights up but nothing is coming into the machine
- I have not had the laptop 10 months and its always connected to the wall/power outlet
So if it is the motherboard, I wouldnt be too surprised but Ive know MSi to make excellent motherboards, hence the reason I spent 2500.00 on it. A fellow IT friend said I may want to try a new power supply that has the exact specs your laptop needs. As if its possible the load on the end of the power brick that goes into my laptop may be done for.
I removed the Battery and noticed this:
The inside of the laptop after removing the battery say
MS 1762
DC Rating 19V=9.5A
My Battery says (MSi battery)
11.1 Vdc = 7800mAh, 87 Wh
..But the power brick reads
Input 100-240 V ~2A 50-60Hz
Output 19.5 Volts =7.7 A
He suggested trying a new power suppy but Im concerned its the motherboard (because us IT Guys know the motherboard will get you everytime)
So is it possible? Im not sure why they may have given me the wrong power brick, if it is wrong. He says the specs dont add up, and since each time I press the button and the white light flickers and part of the keyboard, he said it may be the power bricks' node that connects to my machine. Im used to motherboards that are done for the machine shows no sighns, no hints, no flickers. This is atleast flickering, just not coming on .
I know its alot to read and I appreciate all of the techs/other users time.

Thanks guys. Your input is not falling on deaf ears and it seems im getting reputable support via the forums with the MSi tech team.
It really is so weird. Today I tried the process of elimination from a video I saw on you tube. Now, keep in mind, each time the power button is pressed with either their power brick/battery alone in the machine, the power light and the 'battery' indicator light at the front of the machine flicker (each keypress; even if you do it rapidly).
I took the bottom tray off and checked the fan and blew it out with compressed air. Checked the thermal paste under the processor heatsink, checked the processor condition and all looks well there.
Tested by removing one connection at a time then testing for power (all along while testing, keep in mind I only have the 19.5v 7.7 amp power brick.)
- removed D:/ drive secondary then checked for continuity; no luck
- removed all 4 ram sticks and tested one at a time with the power supply connected; no continuity
- removed the keyboard ribbon cable and tested; still no luck
- removed (what I believe to be) the usb ribbon cable (hub with 3.0 ports) and tested for any indicator lights; still no luck
- unplugged the cmos for 5 mins and reconnected; still no luck
*NOTE: when I look underneath of the laptop when pressing the power button, the fan that has the gpu and the cpu heatsinks up against, it actually spins for a brief second; about as long as the power button flashes.
I stopped at some stores looking for a 180+ watt adapter and i couldnt find one that carried it. I wanted to test it before purchasing, so Ive avoided online purchase up to this point. However, I do realize I need one anyway at this point regardless.
My buddy has his own PC Repair shop. He doesnt have a power brick of that magnitude, but cant we get a voltmeter and check for continuity from not only the power supply, but also the jack soldered on the motherboard?
He is saying kinda what Dark is saying... Me, I think its a short somewhere... he thinks the computer asked for too much power from the power supply and probably burnt out the tip because at the time it cut off, I was playing a graphic intensive game, and in my USB 3.0 ports on a single hub, I had the following connected:
- A Logitech USB headset (wired)
- an XBOX 360 wired controller
- A Logitech G700 gaming mouse charging
Ive never had that many power hungry devices connected to one hub at one time before.

Suddenly power off my macbook pro. How do i turn it on?

Battery was charged and i was taking my backup for iphone 4s because i am about to connect my iphone 6 to itunes.
suddenly screen disappear and not turning it on?
i put in charging for 12 hrs but still not on

Hi ..
Troubleshooting: My computer won't turn on
In the future prior to connecting devices, make sure the Mac is connected to a wall outlet, not just battery power alone.

Sudden power off when docking T510 to Dock

I've had a T510 and a "Mini Dock Series 3" for a few years. It has worked fine. However, I recently upgraded to the "Mini Dock Plus Series 3 with USB 3.0" and have an approximately 50% chance of my T510 losing power when connecting or disconnecting. This is a hard cut as soon as contact is made or broken with the docking station. Occasionally it works (though I'm reluctant to keep tempting filesystem problems).
Has anybody else experienced a similar issue?
It looks like in the past, the T61 had a known issue that caused IBM/Lenovo to issue some rubber nubs to cover the metal pins on the docking station[1]. I could try the same here (simply with electrical tape, or some heatshrink), but I'd imagine those pins are there for a reason (to ground the laptop?).
1. http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-67382
Regarding the new dock, I checked the compatibility list[2] before purchasing, as the T510 doesn't have USB3.0. I really only wanted to drive two external displays. The T510 is on the compatibility list for this dock. (The USB 3.0 port functions as an additional USB 2.0 port).

Hello,
No, when I bought my laptop I checked out the serial number of the battery because it wouldn't take a charge. It's number indicates it was made after the defective batteries and isn't part of the exchange program. Running g4 battery update solved the problem.
The computer only blinked this morning so I haven't had a chance to go to or call a service center. I looked through the discussion forums under power/batteries and didn't see any posts about failing power managers, but did see something about deleting power manager files and such. I did run a few cache cleaning and permissions-repairing programs (yasu and cache out x) along with running techtool pro 4 and ttp4 didn't find any mechanical issues, though don't know if a power manager is a 'part' that it specifically tests for.
I do have to visit the local service center for a speaker replacement issue, so could have them test the power manager if you think that is a good possibility

Sudden power off when plugged in

Hello,
My computer just shut down spontaneously when it was plugged in and had 95% charge on battery, and the date reset to 1969 or 1996. It had been asleep overnight but was plugged in whole time. Also recently I had been watching a dvd and the sound changed to all static (distortion) and last night the speakers put out short burst of the static/distortion. Unrelated, any ideas about the problem? I've read all the posts about spontaneous shutdowns while on battery power, but my computer was plugged in and I don't often use it on battery power. I also ran techtool pro 4.12 and all tests passed.
thanks,
charles

X230 suddenly powers off

I have been using my X230 for last two years without any problems and it still works fine except for one thing: very recently I have experienced a sudden power off a couple of times. I don't remember whether it was plugged but my battery is perfect for sure. While operating normally, the power suddenly went off. So I had to reboot it. This happened around 5 times last couple of weeks.
I realized that I have never done a system update since I purchased this so I tried to do that but it doesn't work. (See my another post below for this issue.)
Any help would be greatly appreciated!
Solved!
Go to Solution.

I am experiencing a similar problem with my 2 year old ThinkPad x230 laptop.
In my situation, the computer goes completely dead instantly on a random basis. It is like the power supply just disappeared. No attempt at a normal shutdown process. Just instantly dead with black screen and no indicator lights..
In my situation the problem happens regardless of whether the computer is operating on battery only, battery + A/C supply or just A/C supply. (Just in case I recently ordered a new OEM 44+ battery which has not arrived.)
I have completely updated WIN 7 64 bit Pro, all drivers, and Lenovo Solution Center software.
I scanned for viruses and malware using Norton, Norton Power Eraser and Malwarebytes: all is shown as OK.
I replaced the 180GB SSD drive with a new Samsung Model 850 SSD 500GB. Same problem.
Ran every hardware diagnostic tool I could find on system checking SSD, memory and all other hardware. All reports as fine. CPU temperature is 45-52 degrees C max. SSD temperature is about 34 degrees C. No noticeable hot spots on case.
Updated BIOS. Same problem.
Disabled hibernation. Same problem.
(Perhaps related is a message from Lenovo Solution Center that a hidden (non-lettered) partition on the SSD is 95% full. I assume this partition, which is labelled "Data" like the D:/ partition, is some sort of system related log or backup separate from the backup stored on the D:/ partition. I cannot find any solution on the Lenovo website explaining the purpose of that hidden partition or how to expand it beyond the current 99.99MB size.)
Any suggestions?
Thanks.

I am having MacBook Pro 3 yrs old and today while I was watching some movie on it suddenly it got power off and when I am trying to start it, it's power button is not working even the round button on external left side is not showing battery lights. But when I connect it to chrger then Charger only gives green light and even the external round button only shown 4 green lights (if charger connected). I don't know what to do now

Sounds like you need a #1SMC Reset
1. SMC reset
>>Instructions to reset SMC
Disconnect other non-Apple and external hardware except (if applicable) a mouse and keyboard until your finished repairing your machine.
Problems solved: Fans blowing with no activity, machine is not booting, power button pressed and nothing happens, problems with indicators, Magsafe has wrong lights, battery is not charging, monitor and graphics issues etc. If the battery is not charged (from like letting it sleep too long), let the Mac charge up awhile afterwards.
Will not hurt the machine resetting if it's not broken.
Other related hardware problems (optional):
Check battery status: Hold option/alt key down while clicking on the battery icon in the menu bar, top right corner.
Magsafe: Use the correct/matching power supply charger with your Mac, not a less powered one from another Mac.

Mac Pro early 2008 power off suddenly alone and gives a long beep on startup

Hello everyone! Can you resolve the problem reported? I have 6 equipaments identical to those with the same problem, some worse than others, and only two barely functioning, others are stopped. They power normally and suddenly alone they power off , and after that I only can power on again , after hours waiting or only the next day , and when it's power on , on startup , they give me a long beep , before the chime , then I can work for a time (minutes or long time , it's not secure)
I talked with Apple Computer (from USA) and they do not assume that the problem exists and that many users have the same problem, worldwide.
If you're not satisfied with the result of Apple, we will have to press them to assume the defect and promote a recall on these equipments. We have many users with the same issue (MacPro off alone)

All places where I have my equipments (they are in 4 different places, but I have tested them in all four locations), are electrically grounded, the electrical networkstabilized, reviewed annually and I use UPS minimum of 1.5 KVA (I have two UPS of 3.75 KVA) . I tested with the original HDD , with all the applications that I use installed , only with the system installed and the same procedure on a new HDD and got the same result . So , it is not eletrical problem . I have iMacs , MacBooks , G5 and MacPro early 2009 working in the same places with no problems . I tested all the sites with three different electricians and all
approved my Electric networks . As I know, all Apple equipment have
surge protection, precisely to prevent thecomponents from being damaged
by electrical problems. Again , it is not eletrical problem .

Well the blinking light shows it's charging, however just to make sure.
Reset the SMC, then connect the machine to a power source that doesn't have a lot of other power items on the same lines (in the walls) in the same room and see how it is in the morning.
For instance use a powerline in another spare room that isn't being used as much.

Suddenly my ipod power off and it remained off

Hi,
My 4 day old ipod nano Suddenly fot power off and its remained same. Its not power off. I tried to connect with pc. It is not responding. I can't on it. I tried to restart it with the hold button on-off and holding the menu and center button 10 seconds. It is responding at all.
Plz Help.

your ipod is currently carrying very little battery, which is not sufficient to turn your iPod on, can you connect it with an iPod wall charger or an iPod speakers dock system i.e. iPod HiFi.
If you cant find, please try to do a Reset while your iPod connecting with your PC
