Have exactly the same problem with my Dell vostro 1000. tried everything..once it worked well after registry cleanup(Regcure)and virus cleanup(McAfee) but now scanning for malware sometimes causes it to shut down then other things aswell like everything you mentioned..:-🙂-(...
 

Hii
@cors
thr is just a option of uninstalling the processors in contrl panl device mangr
does it harm if i uninstall one processr??

plzz help
 



Dobanto

plzzz let me know that u uninstalled one of the processrs by what steps ??/

I encounter the same problm
 



Hii Kie

I joined this forum lately
but u r rite nd if u havnt initiated the step
i m with u
 

 


Did you find a fix?
 
Jim most of are having the problem of the laptop shutting down and starting back up with out any warning, this has generally been when running on power supply.

When mine runs on battery is rarely has the problem, but still exists.

I Have replaced power supply with no change, problem still exists which led me to the IC or Capacitor problem.

Try this link it may help your problem does not sound the same.

A client gave me an A200 to fix.
It had 320gb as main drive and 200gb as secondary drive.
I tried to retrieve data from the 320gb drive, but it was seriously messed up.
I bought a replacement 320gb drive and tried reinstalling vista.
Machine kept rebooting at almost random points during install.

Long story short:
XP Live cd worked fine ONLY with no HDDs installed.
Only way to get vista to survive the install process was to only have the 200gb drive installed.

I read the service manual and some other stuff. Looks like there may be a hdd capacity limit of either 200gb or 250gb each drive.

Can anyone else confirm if this has made a difference for them?

 




Hi, I am working for the Salvation Army in West Africa and have had the same problem with my toshiba. IT support is telling me similar things as everyone else. Where did you get yours fixed and can you post the contact information so I can call them.

Thanks

 
You probably don't monitor this thread anymore Corsa, but your method is allowing me to reinstall windows as I type!

I tried replacing the hard drive, inverter, cpu fan, and video card to no avail. I was trying to avoid the mobo since it costs so much. Nowadays the mobo is cheaper than the 100 smackers I paid for the video card a year ago.

I'm still wondering if its a mobo or cpu issue in case I want to resolve this later. Normally I wouldn't care, but this laptop has a french keyboard that my portuguese wife enjoys using here in the states. Thanks again! I think I may get some brownie points with the wife!


 
To my knowledge the only permanent solution is changing the NEC/TOKIN 0E128 Proadlizer Capacitor. All other solutions are temporary as they are just like providing life support systems while the capacitor is dying. Irrespective of what you do the capacitor ultimately dies. If one has time and patience then it is not very difficult to change that. Removing the old one is the most difficult part. Still the job can be done in 1-2 hours. I used a plier to crush it, which essentially removes the black plastic part. Then I used a a small and sharp flat head screw driver to chisel it delicately. One can use a small hammer or the plier itself to gently hit the sharp screw driver to chisel out the remaiining capaitor. Intermittently I used a small USB vacuum cleaner to suck out remaining tiny pieces. It is now very cleanly removed and I am waiting for my replacement capacitor to arrive. One can either use the exact same part as replacement or use several of smaller capacitance low-esr tantalum capacitors. The former apparently has limited life and hence people are going for the latter. I have ordered both but will probably use the former. I may upload some pictures later but for the timebeing the following links might help others make up their mind:

Wow, that's great info! Let me know how you make out with the capacitor change. I was able to install windows, but it goes back to a black screen after install is completed. I may try this myself if you have success. Pics of your project would awesome!
 
I've just ordered the capacitor too. My problem will be to find someone who will do the job correctly now. I don't think that heating the crap out of it is the correct way?
 
Some people have used heat gun to soften/melt the solder of OE128 to facilitate its removal. However, I just used physical means to avoid any possible damage due to heat. Other usual precautions such as disconnecting AC power, removing the battery, wearing antistatic wristband, etc will have to be followed in such disassembly procedures, of course.

In the first link of my previous post STEPS 17-21 show the OE128 Capacitor in A205 (apparently). In A200 the capacitor will be visible only after the fan has been removed. My replacement capacitor is yet to arrive but I have included some photos in the link below to show what I have done so far. I may have to just melt the existing solder on the terminals (and perhaps add a bit more solder) and stick the new capacitor there. I will update again once it is done.

Thank you very much for this post... Very informative and helpful... still waiting for the update Sir... 99% hoping that this post/solution is the one i need for reviving my A205.... Thank you!!!
 
Yes, its done! Solved!! Perfect!!!

I have soldered the new OE128 cap and my A200 is working perfectly again after nearly two years of gradual and painful death. I just added the solder on the new OE128 cap at eight locations corresponding to the tips of the four pads/terminals. Then after placing the cap on the pads I simply inserted the hot soldering iron tip to touch and melt off the solder already added there. Although I first added the solder onto the new cap the same results could be achieved by adding the solder onto the tips of the pads, placing the new cap over them and then melting off the added solder by touching with the tip of a hot soldering iron. The photos given in the following link might help those who want to try the same:

Of course, one could also do soldering in a more conventional fashion by feeding the solder wire onto the hot iron tip placed at appropriate locations.

Now do not have any more doubts. This is a 100% sure and perfect solution (until the cap dies again, of course) not only for A200 but many other models of Toshiba that use OE128 or OE907 cap and exhibit random restarts, freezing when AC is connected, etc, etc.
 
Those who want to replace their NEC/TOKIN capacitor with apparently more durable tantalum capacitors may see this:

When soldered, tantalum caps look like this: http://www.google.com.au/imgres?q=a305+toshiba+tantalum&hl=en&safe=active&sa=X&rlz=1W1ADRA_enAU347&biw=1280&bih=799&tbm=isch&prmd=imvns&tbnid=SHHrTeWmdgExmM:&imgrefurl=http://www.forumnow.com.br/vip/mensagens.asp%3Fforum%3D32226%26topico%3D3029069&docid=xQgzmrRdRowFQM&imgurl=http://img823.imageshack.us/img823/5528/trabalhopronto.jpg&w=640&h=480&ei=uHcTT7bVCMPJmQWf8tn-CQ&zoom=1
However, the specs of tantalum cap must be chosen carefully, especially its ESR ( http://wiki.xtronics.com/index.php/Capacitors_and_ESR ). The rated ESR of OE128 is 2 mOhm and hence the ESR of each of the four 330uF tantalum caps soldered in parallel should not ideally exceed 8 mOhm (In practice, somewhat higher ESR might still be OK). The following cap seems to match most of the specs:

I opened my A200 today only to find out that my motherboard looks a bit different than yours. The most disturbing was the fact that there's no need to remove the fan in order to access the capacitor. What is more, there's not 1 but 10 small capacitors.
I'm pretty angry right know as I've been waiting two weeks now for OE128 coming from Hong Kong.
I'll post the pic of motherboard later today.
Can somebody advise me what to do here?
I'm really desperate and seriously considering new laptop tomorrow afternoon.
