Toshiba Satellite A200 Random Shutdown

[abdelali7891]

Hi,
I had same problem with my Sattelite L300. Motherboard has a defect in one Proadlizer film capacitor exactly on the back of CPU, the original ref. is nec-tokin 0E907 (900uF/2.5V) or similar code. I've replaced it by 4 tantalum capacitores of 470uF/2.5V each and 2 capacitores of 220uF/2.5V, all in paralell mode in same old place of nec-tokin component.
Vote for me...

Can you help me to do the same thing ? I cant find the nec-tokin 0E907 (900uF/2.5V) in my country.

You can order OE907 online from the following or similar sellers:
http/www.wiisingonline.com/NEC-Tokin-0E907-OE907-Proadlizer-PF-A-Capacitors-High-Speed-Decoupling-Device-PFAF250E907MCBTE-p-4625-272.html

Then follow a procedure similar to what is shown here:

Also decide if you want OE907 or tantalum caps, which are apparently more reliable . Most importantly read all the relevant posts and links given above before jumping into it.

Actualy I'm a beginner in electonics, all what i want is to fix my laptop, the cost of ordering OE907 online + shipping fee = 50 $ ( expensive in my country )

Can you just write me the exact reference of tantalum caps, that i have to use ? and also where will i put it in the mother board.

Thank you.

I have repaired two Satellite A200 laptops.
I replaced the Proadlizer capacitor with eight of GRM31CR60J107ME39L 100UF 6.3V ceramic capacitors.
I purchased them from X-On.

Hi
I know that is happend loong time ago but now my a200 is having the same problem like you had with yours, i'm thinking to use that thermal paste but i was wondering if you found out what was your problem with your laptop. i've reinstalled w7,xp,vista managed to update bios only with vista (original OS provided with the laptop). I've tried everything and now i've changed in bios from "dynamyc cpu" to "always low" and is kinda working but slow. Please help.thank you

hi there br_15. just thought i'd let you know that i got it fixed and it wasn't the motherboard but it was an internal fault. the guy in the shop wouldn't tell me exactly what it was though (like it was a government secret!).
he had used a prog called speedfan and upgraded the bios (not sure where from as i had already checked on the toshiba site and had the latest version).
just before i put it in the shop it had only been working on the battery and whenever i plugged in the power cable it would switch off instantly.
i'm guessing that the fan speed had something to do with it obviously, but i don't care anymore! it's working now and i just wanted to say thanks for your help.
Cheers, Dude! (or is it Dudette?)

Thanks to all. My A200 would start up but often switch off before getting into Windows. I replaced the NEC TOKIN OE128 with 4 Kemet 2.5v 470UF from RS Components Au stock Number 147651. Getting the old NEC TOKIN off was the tricky part. In the end I just used brute force to mangle it and pealed the remains. Tin the circuit board and caps before soldering. Working fine now after several hours.

I have an A200-1YO, 1.66ghz, upgraded to Windows 7 RC and 4Gb 667mhz PC 5300 RAM.
My problem started about a month ago when i was still running Vista Home Premium and 3Gb of Ram.
The machine just started switching itself off randomly. No warning, no error codes, no shutting down or logging off screen...just instant OFF.
At first i thought it was a virus so i scanned the hell out of the whole laptop with my Kaspersky Internet Security 2010 and found nothing. Sometimes it would be on for days then suddenly switch off. sometimes when i plug in my external hard drive or my IR remote receiver it will switch off and sometimes it won't. The most annoying one is when it switches off about 2-3 mins after switching it on and i have done absolutely nothing to it.
I have blanked the hd using DBan and installed Windows 7 and it worked fine for a week or so until it started happening again.
There seems to be no repeat action that causes it to switch off. I have read about the overheating ideas and although i have had the laptop for about 16 months the airflow out of the vent on the side seems to be the same as it always has been..I keep the laptop raised at the back to improve the air flow and it doesn't seem to be overheating.
I have run a program called RealTemp and everything seems to be running within acceptable parameters at between 74-79 centigrade and the max showing at 86 degrees.
The ram i have upgraded to and installed is the correct type for the machine as i used Kingston's ram check function as well as checking the Toshiba website, plus it has been a long time since i installed the first 2gb of ram upgrade and nothing happened then.
The laptop is out of warranty so it would cost me an arm and a leg to get it fixed or at least looked at by Toshiba.
Has anybody got any ideas or suggestions as to what the cause may be??
If more information is needed please state what details required.
Many thanks in advance.

As mentioned earlier, I had replaced OE128 with a new OE128 in my A200 which worked perfectly for 7 months and has just started the restart problem again. Actually I was not expecting it to last that long anyway and had already kept tantalum caps ready. However the tantalum caps that I have (RS Stock No. 548-3337) are of a significantly higher ESR than OE128 and hence may not work, in which case I will go for 147-639 or 147-651 . What I had done earlier is shown here:

[Notsosure]

As suspected, my spare caps with rather high ESR did not work so I have gone for RS Stock No. 737-2832 (Case V, 470uF, 2.5V, 6mΩ each) which is working fine in my A200. Please see my photobucket for additional photos http/gs138.photobucket.com/groups/q251/S1BXDWUERU/ and http/www.badcaps.net/forum/showthread.php?t=8991&page=14 for more details.

Yes A200 here as well which has been shutting down at random .... after many thoughts finally gave in and bought new battery £13.99 on Ebay ...seemed worth a try. So far seem to be stable and have powered down the battery to zero several times to get the battery fully loaded and hoping that might have some effect on battery uptime as well. Good Luck ....

not hopeful this is the end and have an Equium with a flickering screen problem as well ... been in twice to get fix.... never lasts for more than 3 months ... don't even want to think about that one.

Hi There All!

I don't mean to be rude . . Computer Engineer here! . .but this is ALL BUNK! . . the problem with the A200 is simple . . . Toshiba dropped the ball on the fan exhausting into your desk, or maybe even lap! . . "Have you burned your thighs on this puppy yet?" . . In canada there was a very "Quiet recall" by certain retailers that were getting sick of these overheating complaints . . .Toshiba in its lets go the "extra inch" model, graciously repaired/replaced the fans in the laptops of it most ferverent complainers, thus absolving themselves from admitting it was a ridiculous design . .and those suckered into buying this unit from glossy well-hyped advertising should have had the refund/or rplace option! . . So there you have it! . . .if you stuffed insulation in the cooling coils of your refrigerator or radiator in your car, how well would they operate? . . So sorry to see so many trusting people duped by yet another mulinational swindler! . . . ."Hello Lenovo!" . .really too bad, Toshiba for years, was THE name in notebooks!

Best of luck all . . . no ill will intended by any of my comments!

You are an idiot and you make Canadians look like morons! Explain how it's an over heating issue, if;
A) Works fine in safe mode, no over heart WHAT SO EVER> Even though Safe Mode loads minimal drivers, based on what you said, it should still over heat.
B) Doesn't crash once during fresh install of Win 7, only after all drivers are loaded did it crash again.

Give your head shake "Computer Engineer" Ha ha ha! I do tech support for a living and I get the "IT" guys or "Computer Engineers" all the time, and they are the worst ones. Think they know it all but don't have the slightest clue. YOU sir, are one of those.

I also have a similar problem with one of these A200 laptop failures.
Congratulations Toshiba, biggest piece of crap I have ever seen.


Mine is slightly different fault. I can charge the battery to full power, laptop will not turn on during this phase. After charge I remove the power supply and the laptop runs quite normal on battery for a couple of hours till the battery goes flat.
I then have to do a recharge again. If I plug the power unit in whilst the laptop is running it stops completely, instantly, switches off, only lights are the power light and orange battery charge light.
This switch off is instant. I cannot start the laptop using the power supply at all. A couple of lights flash and that's all. If I unplug the power supply I can start OK.
I cannot start it with the power supply with the battery removed. I doubt it is due in any way to software.
I think my problem is related to the power socket. I have pulled it to bits and noticed the power socket has four wires coming from it to the motherboard. The power supply has a two wire plug. What is it with the four wires in the laptop.
I think it is some sort of switch over system within the socket that somehow stops power from the battery and connects the power supply to the motherboard whilst letting the power supply high voltage go direct to the battery charging system. I wish I could get a circuit of the laptop and then I could figure it out.

My history,
40 years in electronics from broadcasting to microwave to optic fibre then changing over to computer building and repair including most laptops. I update apple laptops, never had to repair one so far in the last 15 years or so of computer repairs.
Need I say I use apple and have done for several years.
Once you move from the dark side you will never go back.

If you have a Proadlizer in your A200 then replacing it might work, as suggested below:

Hey guys

I also have a detective a200. My request is would someone please post fresh links to photos of the replacement job as the photobucket links appear to be dead (or is it just my phone browser not being able to open them?). I am specifically looking for the tantalium cap replacement pics. Thanks in advance for any post and to all the info from the previous posters. Also any inside info of where is best to buy the cap in Britain would be appreciated.

I had checked the link several weeks ago when it was showing pics but not the text but when I clicked today it showed everything. Try your comp if phone does not work. My RS Stock No. 737-2832 has been working great.

You can try this seller: http/uk.rs-online.com/web/

I have a friend who asked me to look at their a205 and I think this cap is the cause of the issues. I am in the US and looking for a supplier. I found this at mouser:

http/www.mouser.com/ProductDetail/Kemet/T520V477M2R5ATE009/?qs=%2fha2pyFaduivgpGE%252bjZ5ZFxKn1nmwoR7frkiN5VZIOmIlfuadYdO2Q%3d%3d

and this at digikey:

http/www.digikey.com/product-detail/en/T530D477M2R5ATE006/399-4127-2-ND/818988

I think i will go with digikey as I used to use them all the time years ago and the price is cheaper.

It seems to be the same specs and package size to me but my hardware days are pretty far behind me (I am a programmer now) so I just wanted to confirm. I have already taken the machine apart and can confirm the prodalizer is in there and its a oe128.

thanks for your time and all the research and posts so the rest of us didnt have to.

The height should not be more than 2mm. Try the following:

Thanks for the quick reply. I will get some ordered and heat up the soldering iron.

Hi guys!
please help me to solve my laptop problem..
I am using toshiba satellite M500. when I freshly start my laptop it shut down it self few times (3-4 times) then it is working fine for 20-30 min then again shutdown down it self (same problem every 30-40 min). When i use my laptop i always use the battery and power supply.
someone told me this may be because of the missing windows files, so i format my computer and reinstall windows 7 but still i am having this problem.
when it is workings in safe mode there is no such problems.
when my laptop shut down there were no error message or no blue screen. some times after sudden shutdown it turn on it self....oh again same proble. please help me guys to fix.

Seems like a Proadlizer problem but not very sure if your model has one. If it has a Proadlizer then replacing it might help. Google search does suggest that some M500 models do have Proadlizer (but you may have to open yours and check to make sure):
