Problem solved. I replace the Nec Tokin by the 4 tantalum capacitors, and now the reboots don´t occur anymore.

Hello guys. I know that this is a very discuss question, the problem with Nec Tokin that this Toshiba A300 have. A few months ago, i had one of this, with the known Nec Tokin problem,but the symptoms was very easy to tell that was really the problem in question. I made the repair,and worked...

Why sometimes we have to go to the hard and long way, when the answer to the problem is so obvious and simple: It was the f***in CHARGER ! Last night, i thought:well,lets try again with my universal charger, that i already had tested with NO results. And bingo!, the laptop turns on,fully...

I already tray to use the laptop without battery,forgot to mention that.NOthing No leds of any kind. The charger seems ok, by the test with multimeter i made.

Hello I have a laptop from a friend that won´t turn on. Completly dead.A few months ago i switched the power jack, because of a broken inside pin. Now i dissassemble the board,check all soldering and all semms normal. Check condutivity with multimeter ,and was ok. Check power suplly,and was...

After doing Sistem restore, right now is updating Avast. Until now,everything is fine. Feedback later.

I think the problem is not hardware,such as batery or charger,because i put the laptop just in bios mode, and didnt shut down. And in Safe mode is in this moment working for about 45 min, with no problems. I think the problem is software. It instaled one windows update, one Adobe flash update...

Well, problem solved,or sort of. the problem,aparently was the jack of the power suply. I got a new one, and the laptop powered right away. But now i have another problem,that i dont know why is happening: it shuts down with no reason,right after windows stars. When i solved the problem,the...

Progress . Yesterday i remove the back cover of the notebook, which is big and gives me access to the DC fuse door, as the door itself , so getting to do some testing voltage and continuity . Continuity on laptop , it's ok . Also on the fuse . But this time I tested another thing that had not...

Well,by the time i replace the DC jack, i check the continuity, with power off,and voltages with power on. And it was ok. What is more strange, is when i made the first tests, the board was dead, no readings. But suddenly i had cooler fan spinning(that i plugged to have some visible signs of...

I think, with time and patience, i´ll dessassemble it again and check everything,resolder the dc jack,or maybe buy another one, they are cheap. In the mean while, i already check for 2nd hand board at Ebay and found ate 30/35€,in that range. The lap top,despite being old, is in great shape,and...

And if the problem is the charger circuit itself, is there any solution to this? A new mother board?

Yes, i loose power from the adapter and the laptop is only powered by the battery. But before i mad the repair i try a new power suply ,(generic, multi voltages) and the laptop loose power as well. And i try too to test the power suply with a multimeter right after plug out the power suply from...
