Hello guys,
I am having an issue here, and I would really appreciate your help !
Earlier today, I cleaned my old laptop's fan (Toshiba Satellite P300) and change the thermal paste as it was getting hot and noisy.
To do so I had to dissemble the whole laptop (impossible to access the fan otherwise : crappy design...). Anyway, it was not my first time disambling this laptop and I cleaned it.
After the cleaning, I tried starting up the computer and here is what I noticed on start-up:
- when using battery only (no power supply), it starts fine
- when using power supply only : the power supply led turns off and the pc shuts down immediatly
- when using power supply and battery : the power supply led turns off immediatly as if there were no power supply unit
But, when the computer is off, the led indicating that there is a power supply unit is on !
So, I have to let the battery charge while the computer is off and then use pc on batery only (then it works fine until the battery is empty).
Here are a few questions to help me understand what is happening :
- could this issue be related to the cleaning operation I just made ?
- I hear 2 short bips on startup, what does it mean ?
- it looks like everything is working fine when the battery is full (fans, ram, ...). Still, can the problem come from the motherboard or is it only power supply unit issue ?
Thank you very much for your help !
