Laptop switches off randomly and won't start up

6 down vote favorite2
My problem is that my laptop suddenly and randomly switches off on its own. There is no blue screen, no error messages, the pc just goes off as though somebody pressed the power button. It might happen anytime from within 5-10 mins of starting up, to maybe an hour or two later. Sometimes it works perfectly fine and never turns off. And once it shuts itself off, i can't power it back on. If i press the power button to start the laptop, it turns off again in about 2 seconds before even the POST can start. If i remove and replace the battery and try again later or shake up the CD drive and fan a bit and retry, it might boot up again and run for some random period of time before the same story repeats.
plz help
thanks in advance..

thanx man! but sometimes it works fine like now... but if i shut it down it will repeat the story for several minutes

Iphone 4 turns off randomly and won't turn back on unless it's plugged in

Iphone 4 turns off randomly and won't turn back on unless it's plugged in.
Has anyone had this problem?
If I leave the phone (thus not doing anything to it) for an extended period of time say 2 hrs. It will have turned off and you can't turn it back on unless you plug it in, but it's got heaps of "Battery" left.
Ever so often it will turn off randomly as well, and can't turn it on again.

If your iPhone is powering off, this is not normal.
Try restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup. If no change after doing so, your iPhone has a hardware problem. The iPhone includes a one year warranty.

My Iphone 3gs Os 4.3.5 switch off randomly and it wont switch on untill you plug it!!

Since the update for IOS 4 (it could be not related as well) and my iPhone 3gs is switching off randomly
- it may switch off while using any application (Mail, Camera, photos, facebook...etc)
- when you switch on it stays on apple logo until it crush down again,
- sometimes if you try to switch it on again, it give battery low even though the battery could be full
- the only way to switch it on again is to plug it into any power source (PC or wall)
- I'm using the latest version (4.3.5) since i have hope in every released update
if you need any details please ask for it

Honestly I replaced the phone battery with a battery from the local market (I don't even know if its original or not) but it cost me around 50$, and it worked perfectly since then.
so its either the battery is not compatible with IOS 4 or its simply dead!
best of luck with yours...

MacBook Pro Mid 2014 shut off randomly and won't turn back on.

Hello,
My MacBook Pro(Mid 2014) won't turn back on. I was just typing up my essay and it just turned straight off and won't turn back on. It has happen several times before and all I had to do was press the buttons(SMC method) and the PVRAM thing and it would turn back on. But now it doesn't turn on at all. How do I fix this issue? I had went today to the Apple Store and had a appointment at 3:15-3:25 and I was late by 2 minutes, so they couldn't help me and offered me to come back at 5PM, but will busy so I asked for 5 Monday. Does anyone know what the problem might be? Back when it was operating it would shut off whenever I was using it at the random times. This is my first MacBook so I don't know if it's suppose to get Hot and loud sometimes when operating and then cool off afterwards if that helps out. It shutoff last week wednesday and doesn't turn on at all, but will charge to fully green though. Anyone got any suggestions? I do have a MacBook screwdriver to open it, so if anyone knows anything about the inside and how to resolve the issue it would be great. I don't know how to remove the battery so if you do know please tell me or some keyboard trick would be helpful! All my data is on this so I would like to solve before Apple erases my data.

IPhone 4 turns off randomly, and doesn't start up unless its on the charger. Hard resetting it when its turned off doesn't turn it on either.

My iPhone 4 is running iOS 4.3.4 and it suddenly turns off randomly, usually when the batery is around 85% or so. When I try to turn it on the normal way or hard resetting it, it doesn't turn on. It only turns on when its connected to a charger, and the time and date resets to 7.30am, January 1st 1970. I have no idea why is this happening and how do I resolve this issue? I really don't want to go get it replaced as its too much of a hassle and Im leaving to another country in 2 days time..

It also starts charging at 70% or so when it turns on..

My Iphone 5 has switched off automatically and will not start up again what has happened?!

My Iphone 5 switched itself off lastnight and has still not came back on. I have had the phone on charge so that is not the problem. Is there any suggestions on what the problem is?

Try holding down both home and sleep buttons for at least 10-15 seconds and see if it powers on. If not, it sounds like you may need to get the phone serviced/replaced at Apple Store.

My iPhone 5s turns off randomly and won't turn back on

Yesterday my iphone just shut off randomly even after being charged at 100%. I gave it a hard reset three times and it finally turned back on. But today it blanked out again and every time I try to turn it on the apple icon pops up but then disappears. The screen goes black and nothing happens. I've tried the hard reset and that doesn't work, I've even tried holding down all four buttons and it still doesn't work.

My computer turns off randomly and won't always tun right back on. What should I do?

My computer recently started turning off randomly, some when I move it or just when I am sitting there using it. I have also had trouble getting it to turn back on after it turns off. I plugged it in the last time to get it back on, but I can't always have my charger with me when using it. What do I need to do?

Try resetting the Intel-based Macs: Resetting the System Management Controller (SMC)
If that doesn't help, try Troubleshooting MagSafe adapters

Macbook pro 13" 2012 shut off randomly and won't turn on

The only applications that were open were safari (I was watching hulu) and iTunes. The laptop randomly shut off without any warning. It was in the charger and was around 60-70% power. After it shut down the light that was on the charger turned to a faint orange blinking light and now is a faint green blinking light. This is the first time this has happened. I can't get the power to come back on. Need help asap!

Try resetting the SMC
Desktop Macs
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

Intel imac switches off unexpectantly and won't turn back on

It only just started happening after 7 months. I've tried removing and replacing the RAM. Sometimes it works, sometimes it doesn't. I unplug and re-plug everthing. Sometimes that works, sometimes it doesn't. It turns off after approx. 2 hours and sometimes sooner if I hit the 'dashboard' button on the mouse.

A couple of things you can do to test that mouse, mopea . . .
1. Go into System Preferences>Keyboard/Mouse.
Select the little button at the top (I'm assuming this is what you're called the "Dashboard Button". Then from the pulldown menu, select "Off."
Does the black screen still happen???
2. Do you have an older Apple (Non-Mighty) mouse you can use to test?
It might also be a problem with your power supply.
Or your (as I understand it) failed attempt at upgrading messed up some files. But let us know about the mouse suggestions above, OK?
EDIT: Have you tried to apply the 10.4.9 COMBO Update?
You can find it here:
ComboUpdate
(If you do, make sure all your peripherals are unplugged from the Mac first.
In your case, I would repair permissions before & afterward.)

G70-246US Laptop has black screen and won't start

Hi Everyone,
I have an HP G70-246US laptop. I received an errot that the computer could not find any Boot Disks. I turned it off and rebooted the computer and it would not come back on. I see nothing but a black screen. The power button light comes on but the hard drive light does not.
There is no sound of system startup, none of the f1, options work. The power button and the wireless button are lit and the dvd player allows me to put a cd in and eject it but nothing works.
I took the hd out and put it back in to make sure it was connected securely and still nothing. I am trying to get an idea of what needs to be pinpointed before I purchase a new hard drive.
Unfortunately, I am over my one year warranty time period. I really need to figure out a resolution soon as I design websites and without my computer, I can't finish my work.
Any help is greatly, greatly appreciated.
Thanks in Advance.

With the hdd out can you access the BIOS by tapping the F10 key after powering on? If so that would pretty well point to the hdd causing the problems. Your machine came with a 160Gb SATA hdd. If you will be using your Recovery Disks to reinstall you need at least that large to use them,can be larger but no smaller.

Iphone 4 shut off randomly and won't come back on

I was out yesterday and I put my Iphone 4 in my pocket, the battery was on %70 and I took it back out to make a phone call and it must have shut it self off, I tried turning it back on and it wouldn't work. I've tried pressing the home and lock button but that doesn't work either, I've plugged it in to my computer and it;s no responce? The phone is cracked, and I've had it over a year.

Plug it into a wall outlet for at least 30 minutes, then try resetting it, again: Press the Sleep/Wake button & Home button at the same time, keep pressing until you see the Apple logo, then release.
If that doesn't work, make an appointment at any Apple store.

MY IPAD SWITCHED OFF RANDOMLY AND NOW WONT RESTORE! HELLLLLLLP

MY IPAD WONT RESTORE AND I HAVE TRIED EVERYHING POSSIBLE AND I CANT EVEN CONTACT APPLE ABOUT IT OR GO TO AN APPLE STORE! HELPPPPPP PLEASE

What things have you actually tried? Saying Everything Possible doesn't help us at all. is the battery charged? What happens when you tried to restore the iPad? Did you get any error messages? If so what were they? Did you try a reset?
First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart.

HT4528 My iPhone 4 shuts off randomly and won't turn on until I plug it in

even tried to hold down the home button + the power button

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these steps in order until the issue is resolved.

N200 switches off randomly, during boot time and when moved.

Hello everyone,
My 3000 N200 TYPE: 0769-AG2 laptop started to switch off randomly especially when booting, when I moved the machine (i.e.. from one desk to another) or when I pressed gently the bottom left side over the PCI slot.
The situation has gotten worse. I cannot use it anymore due to the frequency of the symptoms.
Actions I have taken:
Operated with AC adapter with and without battery or battery alone.
Cleaned the fan and heat sink.
Replaced the processor's thermal paste.
Monitored the temperature using software.
Formatted the hard disk and reinstalled the preloaded Vista Windows.
Reinstalled the BIOS driver.
Removed one of the RAM memories and swapped places.
Removed the hard disk.
Removed the optical disk drive.
Operated in Safe Mode with and without network support.
Switched off the wifi button.
Excluded through BIOS the PCI LAN and IDE ODD from boot order. Also disabled internal Modem.
And finally, I contacted the UK support where they just suspected a motherboard problem.
None of the actions taken seem to solve the problem permanently. In some cases it worked for quite a while probably due to pure chance.
Remarks:
My machine is out of warranty, yet it is in an excellent cosmetic condition. I only have it for home use. I have never dropped it, smacked it, spilt liquid on it or operated under any abnormal conditions such as on a blanket or a highly humid environment.
*Two of my friends that have the same model face the same exact problem.
*Hundreds of people on the web complain about the same problem with the particular product.
Could it be a motherboard problem? If yes, why did that happen to me and to two persons I know personally?
A motherboard replacement is very expensive relatively to the total value of the product. What could a feasible solution be?
Thank you for your time reading through my issue.

intrasonik,
It sounds like you have taken great care of your system and approached the problem systematically.
I'm going to assume this is not a thermal issue since you have cleaned the fan (and verified it is running) along with replacing the thermal grease. The randomness seems to suggest it is probably not thermal as well.
That the shutdowns may seem to be triggered by movement or pressure in a certain area of the system could suggest an issue with the contacts at the battery or AC, or a short in the system board.
Without doing a repair and some analysis, it would be hard to say with complete confidence.
I agree that the replacement systemboard through service could be perhaps somewhat expensive compared to the cost of new systems with 4 year newer technology. You might consult the hardware maintenance manual on our support site
for part number and proceedure on replacing the system board. You could search online for the best price by the FRU number and I would imagine, could find a reasonably priced board and swap it out.
The service training videos on this system are available here and may also be helpful to you.
Best regards,
Mark
