My Toshiba Satellite L845 shuts down

Hi.
I bought a few hours ago this laptop, and every 30 minutes it shuts down. I've checked if it could be overwarming, but it's not.
Now it shuts down when it wants, tomorrow I'll change it for a new one, but, is ther any problem than I can fix?
Thanks.

Hi Please post your model . It can be found on the bottom of your laptop. Your message is confusing. Are you saying that your PC shuts down while you are using it?? What do you do to start it back up ?? There are a lot of things we can suggest, but you will have to be more specific.
Ps I don't want to sound mean, but there's more to owning a computer that just knowing how to turn it on
Dokie!!
I Love my Satellite L775D-S7222 Laptop. Some days you're the windshield, Some days you're the bug. The Computer world is crazy. If you have answers to computer problems, pass them forward.

Satellite A100 shuts down after memory upgrade

Consider me as 1 of the thickie bunch.. Not even sure wot im talkin bout but here goes n e way...........
Have a Satellite A100 570 ( PSAA2E)..........
Have tried several different online sites lookin for memory upgrade. Didn't have the witt to use toshiba site...... Ended up going with Crucial.........
Ran diagnostic on laptop and was sent the module a needed.or so i thought....... wrong 1 or 1s as i bought 2 x 1G modules in order to " double up".....
Got my money back as they were not compatable with my system.. something to do with density problems....
Tried company called OFFTEK........ they seemed to know what they were talkin about....... I have from Offtek. at present a..........
200 Pin 1.8v DDR2 PC2-4200 SoDimm....... but Toshiba have recommended below......
1GB PC2-4300 DDR2 Memory (533MHz)
Part Number: PA3411U-2M1G
1024MB (1GB) Memory PC2-4300 DDR2 (533MHz)
Theres an obvious difference ...... 4200 and 4300. But im not sure if its a significant difference........... or what it means
Have updated bios to most recent version and basically updated everything toshiba had to offer for this model...........
Ran EVEREST and it recognises the 1G module but when i take out the original 512mb module the laptop starts for about 3 seconds then shuts down...
this repeats about 5 times then complete shutdown.....
I dont like opening the back cover too often but this is the 3rd module ....
Not sure whats meant to happen if the module is working...i.e start up message..not sure if windows recognises 1G module....
Would it be safer bet to send Offtek module and stick with toshiba option.....
Thanks in advance.....

Cheers R2........ suppose at this stage i could start rhyming off a load of star wars lines but uve probably hears them all before.......
N e way......... checked out the link u posted..........very useful......
The module described is identical to what i have.............As with previous reply ( above ) im not sure what to do.........might take up Offteks offer of replacing the module but slightly concerned it might have same outcome......Still not happy bout opening the cover so much........nut needs must i suppose

Re: Satellite A200 - Shuts down for no reason

I was wandering where to post this, and for a long time, lets get help. My laptop, Toshiba Satellite A200, 3.5 years old
*The problem:*
Previously, its used to shut down by itself in the middle of applications without any warning, the shutting down used to be /: Screen shuts down, no input from keyboard or touchpad, but the front lights that signify the laptop is "ON" did remain* so I used to restart it and thought its a OS prob. or a battery/charger problem (replaced both but no difference) and then this thing started being more common and now, the day has come, that it wont switch boot.
*The current scenario:*
When I switch it on with the Battery (without the charger), it powers up, screen switches on, it boots up, everythig normal and at that point if I plug in any compatible charger (I have tried a few), it will go off (the same way as mentioned in bold letters above). If I restart it or start it otherwise while charger plugged in, it wont start except the front lights, the fan, and the most important thing, a sound from the processor (like sparking sound), this sound only is heard while I plug in the charger.
So, please help me out here, I am not sure why it is not booting up

thanks for the advice , but i have already opened the laptop case , the sound specifically is coming from the Processor. it is a crackling sound.
i removed the RAM and inserted the power supply, and there was no crackling sound from the processor, but when i put the RAm back , the sound is there.
just before opening, i tried booting up form a pen drive, and the laptop did boot-up half way in, till the the screen displayed "windows is starting up" , then it went OFF again,
i mean if the CPU is damaged, how cn it boot half way, or if RAM is the problem, how does the windows logo show up, and definitely there is no prblem, with HDD,
and i have replaced both charger and battery .
so what could be the problem?
i can provide more information, or follow any sort of instructions. but please help

Satellite A200 shuts down randomly - I may have a solution

Hello,
I am having a Toshiba satellite A200-1sj, but the laptop have issues and it shuts down it self randomly.
I have changed thermal paste of the CPU and GPU and this is not related to heat because it some times could power off even after first start when the board is cold. I have started the board out of the case, just bare naked with the cooling pipes on it and it would shut again, without its hard, wifi adapter or modem so this is not related to them. I have also tested with another power charger from a friends A200-23k and it still shuts down so its not about it either.
BUT !!! The big but is what I have discovered and I think toshiba is to blame! This issue is related to the voltage regulator some how and it is not working properly for some add reason. I have also found some kind of solution last night after a bios save and exit the fan stuck at 100% and the machine have not shut down since then and it looks like when the fan is regulated and it rises and lowers the voltages then the problem appears.
The sad thing is that i left the cpu from bios at low profile so it will run at only 1GHz and I am afraid to change it within bios because i may loose the 100% fan operation and the machine will get unstable again! :(.
Current bios i have is 2.60 and I am thinking to try 5.30 if the machine starts to shut down again but i think this would be no go because the fan will regulate again ;(.
Is there someone from Toshiba who can create a bios with a constant voltage for the fan so it wont have up and down times which could be less painful for the regulator i guess and may bring stability at decent noise.
I am open to any suggestions,
Best Regards,

YES I have successfully restored my bios.
Here is the URL from which you can download the proper boot disc crisis tool: http://www.mediafire.com/?3ccb9m0kv0m
You first need to make your bootable floppy disk. I have made mine with CRISDISK.BAT from the archive. This is an easy to use bat file and in some cases slight editing may be needed if the usb floppy you are using is recognized as letter B: You just search for "A:" and change the values to B:
After you have your bootable disk you have to delete the file BIOS.WPH and copy the desired bios for your model on the floppy with the same name(bios.wph).
Then you need to create autoexec.bat file. - this could be easy, you just create an text file with notepad and rename it autoexec.bat after you have the needed lines in it.
In my case i used autoexec.bat with the following lines: phlash16.exe /x /s /BBL /MODE=2 bios.WPH
When I used the bat file with mode=3 which is most common way out on the forums it did not worked but with mode 2 things went faster and smooth. Mode 3 took around 20 minutes in reading the floppy disk with a short pauses looking like flashing block by block but on the end flashing result was = BSOD. So for those who are unable to restore the bios with the guides out there you better flash using mode=2 (preserve dmi) just like I did. Still if mode=2 also is not working you may experiment with the other two options remaining.
I will explain those modes for you in case you are wondering.
0 - update the bios and not the dmi
1 - update the dmi and not the bios
2 - update the dmi and the bios (preserve dmi)
3 - update the dmi and the bios (renew dmi)
The bios mode update information above is information I found on the web in another forum so I can not take credit for it.
P.S.
The only thing kept me going when I used older versions of phlash16.exe was that it actually read the disk and it was for more then 5 seconds which mean that the motherboard was searching for the proper image and this can be a successful way to revive your bios.

Satellite A500 shuts down for no reason

My mother's Satellite A500-1EC constantly shuts down by itself. Especially when she uses skype.
It's nothing related with the ac. The same thing happends when its not plugged in.
I updated the BIOS and the drivers, which only solved a previous problem (when it was turning on automatically).
It looks like many people have or had similar problems. I guess Toshiba has found an answer now, but I can't find it anywhere...
Thanks!

Hi
In most case the notebooks (no matter what notebook or what manufacturer it is) shuts down automatically due to higher temperature inside the notebook. This is a kind of overheating protection which helps to prevent the hardware parts from damage.
It would be interesting to know if cleaning the cooling grilles might help you.
I clean my ventilators from time to time using compressed air spray. This blows off all the dust inside the grilles and keep the temperature at lower level.

Satellite A665 shuts down randomly

Hello, I have a Satellite A665 laptop that I got in December of 2010. Over the course of summer and fall of 2011, it began intermittantly shutting down. Sometimes it would do it right on startup, other times in the middle of use...and then it would work fine for weeks on end and not shut down once. When November of 2011 rolled around it started shutting down at random more frequently, to the point where it would not stay on for longer than a minute before dying. I sent the laptop in for repairs, and the hard drive was replaced and the laptop sent back. A month later it began shutting down again, and this time completely died--it wouldn't even try to turn on. So I sent it back in and this time the motherboard was replaced, along with the hard drive again. All seemed to be good, but recently it started shutting down at random when I turned on the computer. I installed the latest Toshiba system pack update (which said it fixed system crashes upon startup) and the problem went away for a few days, but today my laptop has shut down twice for no apparent reason, both times while it was on screen saver/going off screen saver.
I know my laptop is not overheating, because I always use it on my desk, and additionally, it has the extended battery pack on it, so the bottom of the laptop is always slightly elevated above my desk, allowing plenty of ventilation. The fan never has to run on high. I also know this is not a virus, because I've done plenty of virus scans on my laptop and it always comes up virus free. Additionally, it has a BRAND NEW hard drive and motherboard.
I use my laptop intensively for college and I simply cannot afford to have it shutting down on me when I need it. Anyone know what is going on and if I can fix it? Naturally it's out of warranty now, and I can't exactly do without it at school to have it sent off and repaired.

First of all: Im glad that im not the only one suffering from this problem
Secondly: I opened up the bottom case and vaccuumed the laptop and then disabled hibernation/sleep mode.
this seemed to do the trick

Satellite A100 - Shut down by itself and will not boot anymore

Satellite A100 PSAA9A-10U038. Laptop shut down by itself whilst in use. No BIOS upgrades or changes. No lights of any kind showing, no POST.
I have tried the AC power adapter on another machine and works fine. Called Toshiba told me power adapter probably at fault, if I wish to have them look will cost $120.
I'm thinking maybe motherboard died? Any help would be appreciated.

hi Laptop Larry,
try to boot without the batterypack....
can you see the "toshiba screen" while booting?
you can also try to:
- remove hdd
- remove added memory (with no mem the unit should "beep")
- remove odd (cd-drive)
if you cant get the system to boot (able to enter bios, see toshiba logo on screen, no beep)
than it's possible that your mobo died...

My Satellite A30 shuts down on its own

Since last 3-4 days my laptop,toshiba satellite A30, just shut down automatically. I have noticed that possibly it is getting overheated for i can hear the fan moving at a high speed.
Can anyone help?

Hi Vijay,
It sounds as if you have a problem with dust blocking the CPU heat sink. This causes the symptoms that you describe.
You can try removing the dust through the fan intake grilles using a domestic vacuum cleaner, or if you prefer you can remove the plastic cover adjacent to the fan grilles and then remove the heatsink to clear out any debris.
You can find several threads in this forum relating to overheating.

Satellite U305 shuts down and reboots when trying to copy/paste

This is the oddest thing and hopefully someone here can help....
When I try to copy and paste, either through the use of the touchpad (right click, copy = right click, paste) or by using ctrlC/ctrlP, the laptop screen goes white, then shuts down and restarts. This only happens when I am using copy and paste.
Any thoughts? I have no idea why this is happening! Help!

Maybe this helps.

Satellite M100 shuts down automatically after about 10min

Hey there guys :)
My Toshiba Laptop has been powering off abrubptly and on it's own lately.
When I turn my Laptop on, everything appears fine, battery if fully charged, AC adapter plugged in etc. However, after about 10 minutes of use it will just turn off and make a little 'zoip' noise or similar. Turning the laptop back on right after works, but I find that it will only stay on for about 4 minutes before doing the same. Turning it back on again reduces the time it stays on, sometimes not even going past the boot sequence.
However, if I leave it alone for a couple of hours and come back to it, it will stay on for about 10 minutes again, before going thru the same process.
I have a waranty, but I'm hesitant in taking my laptop in because I don't want to lose my files.
So I am hoping someone here has a fix for my problem :)
Thank you,
Osman

Hi
Sorry to said it but in my opinion its a hardware problem. This strange notebook behavior seems to be a simply overheating!
The notebook supports an overheating protection to prevent the hardware from the damage.
If the temperature increases to the higher level the notebook shuts down automatically. This is a fact and nothing unusual in such case.
Mostly the fan cleaning helps but sometimes the notebook must be opened for professional cleaning. But note: I dont recommend opening or removing any cases! You would lose the warranty!!!
Maybe a simple vacuuming would make the job.
Anyway, you said you will not lose the data on your HDD. Well, I wonder why you dont create an data backup You can also remove the HDD and connect it via external USB controller to the second PC and could save the files on the other HDD.
After this procedure you should put the HDD again into the notebook and try to reinstall the OS.
If it does not help I would recommend taking the warranty.

Satellite A60 Shuts Down immediately after pressing power button

My A60 shuts down after 2-3 seconds when I press the power button for openning the laptop. After pressing the power button, all lights come on, but before anything appears on the screen, computer cuts off the power. Fun, DVD and harddisk sound working. At least, sounds are coming from the these hardwares. Also from the buttom of the laptop, I can see the fan is working.
This problems started nowhere. Yesderday, I closed my laptop properly and carry my laptop to my friends. When I tried to open my laptop, this problem occured and I could not open it yet.
I tried any combination of using power supply and battery for power. Non of them is working.
Is there any one had the same problem or have any diagonistics for this problem.
Thanks,
Emrah

@ Etjuh
Dont think its the same problem!
Your problem sounds more like overheating and the cooling modules cleaning could helps to prevent the notebook form overheating and from automatically shut downs.
The vacuum cleaner is a useful tool ;) but be careful if you dont know how to do it please contact an technician!
PS: Do not post twice next time ;)

Re: Satellite A105 shuts down after 60 seconds (NOT a thermal problem)

Satellite A105-s4344 shuts down after EXACTLY 60 seconds. The mobo has been removed from bezels and all un-needed devices removed (DVD, HDD, WiFI etc.). Swapped CPU and RAM with known good ones. Swapped AC adapter and battery with known good. Does the same on AC or DC only inputs.
I have not yet flashed the BIOS (with 60 seconds this would be foolish). But, I am looking into replacing or reflashing with an EEPROM burner. Currently has V 2.0
I am not sure what genration heat detecting this system uses, but it is a possible cause if it is one of the later generations (visit http://www.topbits.com/how-to-monitor-cpu-temperature.html if you do not know that I am refering to).
Prior to reballing the north and south bridge, and flashing I figured I would get some input from you folks. Just to cover all bases ;)
P.S. the first person to ask what OS I am using will get an instant ticket to the bottom of my respect list.

>P.S. the first person to ask what OS I am using will get an instant ticket to the bottom of my respect list.
:) :) :) Best thing I saw in this forum.
Back to your problem.
I am not technician but here just my opinion about all this. The fact is that after switching your notebook ON CPU in just few seconds reaches very high temperature. You can switch your notebook ON and just enter BIOS settings and the same should happen again.
I cannot say for sure if this is 100% thermal issue or not but what else can be responsible for switching off? CPU will be hot in few seconds only. Material change structure with temperature change and I can just imagine some contact will be interrupted.
On this forum we had many similar reports like when cold notebook starts and runs well but after short time switches off for no reason. Maybe I am wrong but for me it sounds like thermal or bad contacts issue. Lets see what other people have to say about it.

My Satellite 2410 shuts down after resuming from Stand by mode

My laptop shuts down when i resume it from stand by. I have Satellite 2410-303 windows xp Home Edition Sp-2.
any help?

Hi,
could it be possible that you have Software installed, that doesnt support the standby function?
Often Programs like Firewalls or AntiVirus Programs are the reason.

Satellite A200 shuts down automatically

My Satellite A200 is less than 10 months old but it has started to just shut down all of a sudden without warning.
When I try to turn it back on it often doesn't reach the Vista screen before powering off again.
Interestingly, when I remove the charger cable it seems to be able to boot up and survive at least for a longer duration.
Any ideas please?

Hi
I think the notebook shuts down automatically due to a higher internal temperature.
The point is that such notebooks supports a overheating protection and if the temperature increases to a critical level, the notebook shuts down automatically to prevent the hardware from damage.
In most cases the air cannot circulate properly due to clogged cooling grilles and therefore the temperature increases to a higher level.
In my opinion the cooling ventilators should be cleaned up.
The compressed air spray is a professional tool which could helps you to get rid of dust and debris.

Satellite L750D shuts down in 2 seconds, can't access BIOS

I have A Toshiba L750D, when I switch on, on turns off within 2 seconds or so. I have tried F2, bios comes up, but then computer shuts down.
I have tried the normal reset procedure, no difference.
I have tried removing memory and trying other memory, no difference
I have tried removing cd, hard drive, keyboard and battery, no difference
Unplugged screen, no difference, shuts down in seconds.
Fan begins to spin, thought this maybe faulty, changed the fan, no difference.
I am assuming this is a motherboard issue? any help appreciated

>I am assuming this is a motherboard issue?
Yes, it looks like the motherboard is affected.
This assumption might be correct since other possible troublemakers have been checked and this did not solve your problem.
Im not quite sure if motherboard replacement is an option in this case since such part is not cheap. I guess would need to check if its an option for you or maybe buying new notebook would be a better solution.
