Toshiba Satellite A300-1BV Turns on and off immediately

[Michele1968sa]

The computer turns on and after one minute it shuts down, this problem occurs both with the battery inserted and with the power directly, I replaced the two 330 micro Farad tantalum capacitors under the CPU, after having reassembled all the presence problem again ... Before proceeding with the replacement of the consendants or cleaning both the fan and the CPU and Graphics Card by putting some thermal paste.
Could anyone tell me how to fix it .. Thanks

check voltage on all BIG gray coils & can you flash BIOS ?

The PC turns on and immediately turns off. Toshiba Satellite A300 - 1BV mod. PSAJ4E-0

The PC turns on and immediately turns off. The problem arises only with the battery and only with power and only with battery + power turns off almost immediately. Following the indications on the internet concerning this problem, it was recommended to replace the 2 SMD 330uF 2.5 V tantalum capacitor located under the CPU. Once the problem has been replaced, please submit again ... How can I do it ...

A nec tokin issue. yes replacing the caps under with 330uf should fix your problem.
4 SMD 330uF not 2 , there are some vids on youtube on how to do it. nothing to complicated
So replace those and post an update

As you can see from the photo I am attaching there are two SMD 330 uF 25V capacitors, while the videos I saw on youtube show the nec tokin being unsoldered and replaced with 4 SMD 330uF 25V.
