Tohsiba Satellite C850 Motherboard Repair no power or no charge (MOSFET Change) Toshiba Satellite Laptop Repair - Troubleshooting Steps For No Power Condition
"In today's episode we have this device from Toshiba C _[and Swansea]_ because this device was not working and does not give any charging signal when the charger is connected. After checking the voltage at the inlet of the charger we found nineteen volts and after removing the card and following a path. _[Inventory path turns out to be this average]._ And it turns out that this MOSFET _[and the type that this specification include on its own training of sixteen individuals]._ On the opposite side, a separation of .93 volts in each of the _[sus]. [And canceled the source and compiler]._ This MOSFET needs a certain value that enters in order to allow the current to pass from the _[tuber]_ to the _[mite]._ Due to the absence of this voltage this MOSFET does not pass the necessary voltage. When I removed this and connected the base with the source, the device worked normally, but with the charger only, meaning that it does not make the switch between the battery and the charger. So after looking closely at the card I found that the second spec on the small second connector responsible for the Asus process is a bit swollen, which is what caused the _[bone]._ _[She changed the specifications and it is also of a comprehensive type. His body is in a chip computer card]._ _[Sea Swansea]_ was working on the computer doing the swipe between battery and charging coach now. So the device as you can see is working normally. We note that this malfunction is very common in this type of laptop. It means if you have a problem with this device or any other type similar to this device, be sure that the problem is ninety percent of those _[seeking percent of this small average]._ " Well, if anybody might fill the blanks here...
Hi, I had the same problem and have solved it by this method. But now, when I turn on the laptop, it works a few minutes, gets overheating and shuts down. The convention system is normal. I think, that the trouble hidden in supply circuts of south-bridge(AMD) beacuse, when I connect the USB(keyboard), it shuts down suddenly. Have you got same problem? pls, heeeeelp.....I dont know what should to do...
salam alaykom. i replaced the mosfet as you said.i got lpower light ok.now new problem black screen can you help me. i give you more information .my computer was working fine, i was fixing the cable adpter by mistake i shorted my computer ( + touched _) spark (cour de circuit---short) so after no power no light .
salam alaykom.my brother.i fixed it the problem was static.so i discharged it(i took off charger and power cable) and then (pressed the power button for about 30 seconde to discharge any electric in capacitor but and then pluged it in and voila its working now.
