Equium A300D-16C - Switches itself off after 3 seconds

I have a Toshiba Equium A300D-16C that will not start up. When you switch it on it begins to start but within 3 seconds switches itself off before it even gets to any type of screen. It then automatically tries to switch on again, then repeats the same cycle of auto off, auto on over and over.
When you put your ear to the bottom of the laptop you can hear the system starting up then you get two very quiet beeps before it switches itself off. Does anyone know what the cause could be or if there is a fix or should i just accept that my laptop of just under two years has died and given up the ghost?
Thanks in advance for any feedback.

> How much would i be looking at to replace cpu/motherboard (not beign a tech wizard in the slightest)
I don't know exactly what is wrong with it as it should be tested before making any conclusion. But the most possible reason is the motherboard - southbridge or power circuit controller. If it's motherboard issue, you will have to pay pretty good money :( as the most expensive part of your laptop. (about 35$-40% from total new laptop price). Don't know even if it's worthy to replace it due to high price. But before, you should contact the Asp (service center):

Ask them what really happened to it and make decision, then, replace or not.

Equium A300D-16C - Keeps turning off after 5 minutes

My laptop keeps turning itself off.
I've noticed lately it overheats faster than usual. When I use it I have to stack it on books but make sure the left side of the laptop is pushed to the side so the book isn't beneath it.
I have tried the following:
Taken the battery out and waited.
Waited for the lap top to cool down.
Use the power cord and remove the battery.
Right now I have changed the power settings and it hasn't turned off as yet, but is there anything extra I should do?
Also was wondering how to remove any dust that may be trapped inside as well as trying to figure out the over heating problem, I can never have the left side of the base covered even if its on a table as it will turn itself off.
Help is much appreciated.

Hey,
> but is there anything extra I should do?
Yes, you should clean your notebook and remove the dust to avoid overheating and make your notebook stable.
Here is a good article how to do this:
[How to clean the cooling system of a Toshiba notebook? |http://forums.computers.toshiba-europe.com/forums/ann.jspa?annID=40]
For example I clean my notebook every 3 months because I use it every day and compressed air spray is really good option for this. You dont need much time and its pretty cheap. ;)

Equium A300D-16C - Battery not detected after replacement

I have a Equium A300D-16C. The original battery was shot so I purchased a Genuine PA3727-1brs 12 cell battery. I have put it in the laptop it appears to charge it but in the corner it still says no battery detected even though its on charge. When I take out the charger it will say unknown remaining.
I have tried the usual tricks of going into device manager and uninstalling the apci compliant control and still it has not sorted it self out. I have also updated my bios to the most recent one. I just wanted to know what else could I do so I can see how much battery is left and if the laptop can recognise i.,

Hello
Is it an original Toshiba battery from an authorized service provider?
Usually the new battery should be detected after first start I would recommend charging the battery while notebook is turned off. Then start notebook with battery only and check if its recognized properly.

My itunes switches itself off after about 20 minutes why?

Can anyone help here the guys in the shop have no idea?
I just leave the i-tunes playing on random and after a while it just switches off - really annoying!

Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
Try a new SIM card.

HP2250tn Switching itself off

The printer switches itself off after the initialisation process or sometimes when trying to print.
Have run through the reset procedure given here - everything out and then insert one by one but it still switches off when beginning to print the test page.
Wondering if it is a hadware fault in the power supply.
Any clues please ?

In a single word, heat. That's my guess.
Check to see if all of your fans are running, and/or the temp of your CPU (if you have the ability to do that. Not all Macs have CPU sensors).

Have you considered your network.
Do you have a reasonable signal strength, what about interference.
Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.

Mac Pro switches itself off immediately after power button is pressed on

Hi there,
I would like to share with you an ongoing problem of my Mac Pro (about on and off 11 month I think). Since its HD changed at the beginning of this year I've been having the problem of "switching itself off immediately after the power button is pressed on." I took it to Milton Keynes Apple Shop and apparently they couldn't replicate the problem I received it after they reset it's PRAM. Meanwhile I read the related posts and discussions about the problem and my assumption was as suggested in the scenarios of similar cause – Power Supply unit. I had a technical chat with ex-Solutions staff from Brighton, he also said it might have been caused by it.
I really don't know what to do because, sometimes attempting 10 or over times of pressing the button I hear the chime and literally 10 or 20 seconds later it switches itself off. And it happened this Sunday morning again, 8 times I've encountered the failure. And the most confusing thing is sometimes I leave it about an hour or two and then it just works and runs fine as it has never have happened.
By the way I left my computer on for a very long time I suspect maybe more than a month it was on sleep most of time when i am not using it. But yesterday I made the mistake of logging off and shutting it down. Now I can't turn my computer on. Highly frustrating and amazingly bizarre technical challenge.
Mind you I am fairly capable of carrying DIY operations on it. Previously I baked my graphics card as suggested in the forum – it works fine at the moment I am waiting until it completely brakes. But this power problem really really puzzles me.
Any opinions, how to solve this cause is highly appreciated.
Many thanks!
Specs:
Mac Pro 8 core
Xeon 5400 2nd Generation Early 2008
10 GB RAM
1 TB HD

The SMC especially on the very first 2-3 months of Early 2008.
Use to suffer from a "restart on wake from sleep" issue.
Some one told me that is not what "inrush current issue" is but that is what I (and couple others) called it.
Best to always have a workstation on 1500VA UPS.
Not share the outlet or cirucit even with anything major.
Yes it could I guess, poor phrase, but put more stress on PSU over time as a result also.
Methods to reset SMC have varied and changed over time. Thanks to web not all the revisions and older versions are kept online though to compare to.
Stories of people going on vacation etc for two weeks to come back to a "dead" Mac Pro started showing up in 2007.
If it had an actual SMC button, use that to reset.
If not, leaving it totally disconnected, and all external cables and such over-night, not for the mere 5-10 minutes.
Unplug but then press and hold power button for 8-10 seconds. And only once. And not to be done repeatedly. That was SMC Reset #3.
I know the 2007 8-core 3GHz had a different PSU than the smaller models.
2008 high end was 8-core 3.2GHz 5400 (stock was 2.8GHz 4 or 8-core)
FBDIMMs draw between 10W up to 15W each, so possible to have 8 DIMMs drawing 120W when maxed out. And heat. I always recommend Mac Pro use fan control to boost the fans a small 400 rpm to expel heat better and keep FBDIMM temps down. Heat, and temperature fluxuations stress and weaken components.
Other than AHT and the tools that a Apple Certified center should have, not much other than to swap out parts, monitor - iStatPro or Hardware Monitor -
And because of all this, I would setup a test system so you have a freshly formatted and installed OS and take it from there, with a better chance.

Equium A300D-16C. not booting after shutdown.

Please, this is a problem i seem not to understand. I have been using my Equium A300d-16c laptop without no problem for over a year until yesterday's evening. i was installing a software(nokia PC suite) which prompted for a restart. the shutting down was normal and for it to restart was a problem. it displays nothing but a blank screen. It is evident it does not boot as when i press the power button it goes of immediately. Only the power indicator is on. Another thing i notice is that the DVD-ROM reads any disc put inside but there is no display of any sort.
My first reaction was that it may be overheating, so i cleaned the cooling vents and blew away dusts from all compartments. but still the problem persists. Please i seek to know what may be the problem before taking it to for repairs. Help Needed. Thanks.

Thanks. There is nothing displayed on the screen. it does not seem to boot into anything, as the powere goes off immediately when the power button is pressed. I have tried to change the ram modules, but still the same problem. i dont know what kind of hardware failure could cause this as it was working fine untill the shutdown. Thanks for the concern.

Recently, when I upgraded to iOS8.2, my iPhone 5c has been switching itself off randomly even when the iPhone says it still has plenty of battery left. Has anyone else had this after upgrading?

HI.
a Couple of weeks ago I upgraded to iOS 8.2 on my iPhone 5c. However, recently it has been switching itself off at around 20-40% for no apparent reason and then goes to the plug iPhone in screen.
please can someone help and let me know if they have had the same problem and how they resolved it
thanks in advance

This happens to me too. Went to the apple store and they check the battery life of my iphone. They took the iphone for 2 days and changed my battery for free. I hope this help you!

New battery isn't detected on Equium A300D-16C

Hi,
This is my first post on the site. I have an issue with a new battery on my Equium A300D-16C. (no battery detected)
The original one that I had for the computer died after two years of use so I had to order a new one as a replacement. I have received it and it itself works fine, giving me 90 minutes charge. But the problem is that it isnt detected by the computer when I click on the power icon on the bottom bar of screen, so I dont know how long I have left with it. Also, the orange light that indicates it is charging should go white upon it being full of charge, mine just starts flashing orange after a while (is this when it is fully charged?).
I took the mains out of my computer a few minutes ago and it cut out and I had to switch it back on again, despite the battery being in and it being full of charge (as it has been in all day and the mains have been in for decent length periods).
What can I do to solve this?
Worth mentioning I am not too good with computers so everything might be best explained really, really simply as I am not the cleverest when it comes to this area.
thanks

> Now when i take the mains power out, the computer cuts out and shuts off within minutes without it being able to be turned back on
Seems the battery is empty and therefore notebook shuts down when AC adaptor has been disconnected.
There are two possibilities:
Either the new battery is faulty or there is something wrong with motherboard power supply electronic.
I think both should be checked.

Equium A300D-16C - display not working

My girlfriend has an Equium A300D-16C which has been having a few problems lately.
For the past few months, whenever she turns the system on, the display doesn't fire up and it takes several attempts for it to come on.
The strange thing is whenever this happens the system does still boot normally as you can hear the Windows 7 start up sound.
I have been looking into this issue for quite some time now and I'm starting to run out of ideas.
Originally I thought it could've been a cabling issue but upon stripping the laptop down I found the cable was still firmly in place.
I have also tried removing the RAM, HDD and DVD drive but it still doesn't fire up. On the odd occasion it has started up when doing this but upon rebooting it hasn't started again.
I am thinking this could be either a power issue or the motherboard is on its way out. This problem is gradually getting worse (it took over 20 attempts turning it on and off this morning) so eventually it won't come on at all.
To clarify, the system will boot after many attempts but most of the time the display will not turn on (not even the backlight). It does work with an external display on the HDMI so the GPU is working.
I have tried holding the power button with no power source to discharge the system but it doesn't help.
I have also noticed that if you hear it boot and close the lid, upon reopening the lid the display will come on but with the wrong resolution (1024x768) which just puzzles me even more.
Any ideas on what could be wrong? I would rather repair this than just buy a new one as its still a decent system apart from this problem.

It is always problematic to discuss about problems that happen from time to time. Ok in your case most of the time it doesn't work but when it works there is connection between display and mainboard.
On this virtual way we can just speculate what the problem can be. Maybe connection to the mainboard, maybe display controller, display cable, display connector. Who knows?
If there is no even backlight I presume display doesnt get the video signal at all. It must be something on mainboard side.
What you can do? You can contact nearest service and ask for help but if they will say that mainboard must be exchanged it will be pretty expensive. You can try to find similar model on ebay with broken display or some other hardware failure (not mainboard) and exchange the mainboard.
It is really not easy to say what can be done.

Equium A300D-16C turns on but the screen shows nothing/stays black

Hi there, I have a Toshiba Equium A300D-16C laptop.
It was fine until now...
When I press the power button, my laptop turns on but the screen remains black / off.
HDD indicator doesn't flash or anything ... ( in case this helps )
I've also tried to remove the battery, hold the power button for 30s and plug the power cord back in... Same thing laptop turns on but screen is black.
I tried to connect my laptop to my PC's monitor using HDMI cable but no success... Laptop turned on but my pc's monitor was showing nothing.
I haven't changed anything inside my laptop or unscrewed it.
PS:
I quite often kept my laptop on the bed/pillow so it may have something to do with overheating or something.
How did I get to this point:
Yesterday my laptop was fine, there was nothing wrong with it... I switched it off at night but when I tried to switch it back on this morning that's where I faced this problem.
Any help would be appreciated.
Many thanks,
Rejanu.

Hello
> I tried to connect my laptop to my PC's monitor using HDMI cable but no success... Laptop turned on but my pc's monitor was showing nothing.
Its very good that you have this test with an external monitor because so you could make sure its not related to internal monitor and its working properly.
Well, you have tried a lot so my personal opinion is its a serious hardware malfunction It could be related to mainboard or CPU in my opinion
I think such hardware diagnostic can only be done from an authorized service provider. I think you should contact the guys. They can help you to get rid of this problem :)

ICloud drive keeps switching itself off on my iPad 2

I have a MBP and an iMac = both on Yosemite and both working with iCloud drive OK.
But I cannot get this to work on iPad 2 with IOS 8 - with either Pages or Keynote. It keeps telling me to set up iCloud - which I do as per instructions - but it sends me round in the same circles!
This is driving me crazy and has wasted hours! I have signed in and out of iCloud several times and enabled iCloud Drive. Then also down to Pages app and checked on for 'use iCloud' Somehow - this switches itself off again after a few seconds! How does this happen?
Why does it not stay on????????
While it is 'on' - Every time I try to use the Pages app I cannot see my iCloud drive documents - and when I try and save it then tells me to set up iCloud!
This is useless to me if it will not work as advertised!

I suggest that you do a update or reinstall of the phone software via the Update Service program. www.sonyericsson.com/updateservice
Hopefully will that solve your problem.
If you get the option to update I suggest that you select to update and also factory reset the phone.
If you only get the option to reinstall you already have the latest version, this will automatically result in a master reset too.

My iPad switches itself off when I'm on the Internet help

When I'm using my iPad on the net it switches itself off and I'm having to turn it back on again and out in my password I only want to use it properly

Hi Lisah,
It sounds like you may have some corrupted files in the operating system -- when built-in apps and features like Camera and Siri malfunction, corrupted files are often the culprit. There are a few things you can do to fix this -- first thing I'd recommend would be to back up your device to make sure you have all of your current data and settings saved. Back up and restore your iPhone, iPad, or iPod touch using iCloud or iTunes - Apple Support
After backing up your data, try resetting all settings in Settings > General > Reset. Try the camera and charger again to see if you still see the same strange behavior. If so, there's likely a corrupted file in the iOS installation. It's pretty easy to reinstall the operating system files to fix this -- you will need a computer with internet access. Follow the steps in Use iTunes to restore your iOS device to factory settings - Apple Support to completely reinstall the iOS files and get a fresh, clean installation.
After using iTunes to restore the phone, go through the setup assistant on the phone and choose the option to Set up as a new iPhone. Set it up as new and test the camera again -- if it works this time, that's a good sign! After making sure it works properly, you can restore from the backup that created before doing all of the resets and restores. This will bring your content and settings back to the phone.
Good luck!
