Hello,
I have Toshiba Satellite A300 which fails to detect hard disk.
Laptop had water (juice) damage.
I cleaned motherboard and keyboard. Everything is working except it won't spin up hdd. Serial ATA power connector is giving 4.05V instead of 5V and disk is not spinning. Disk is working fine in another laptop or over the USB in same laptop. It detect CD/DVD drive, but won't boot of it, because can not spin it too. Same 4.05 volts there.
Do you have idea what could it be? I am measuring that 4.05V on several places over board and not know what is causing such drop. Nothing overheats, checked all capacitors with ESR meter, all OK, checked few mosfets, all OK. Even replaced some of them with new.
I tried booting via USB with linux live (knoppix, ubuntu) and everything else seems to be fine: sound, graphics, mouse, usb, touchpad, keyboard, bluetooth, lan, wlan, card reader.
Thank you very much.
Regards,
Zoran
