If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, until they won't charge up at all.
Check power adapter’s DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. I suggest you get a quote first.

I have a toshiba satillite pro l300. when i plug into mains only the orange light comes on and nothing else.


Try removing the battery and using the power cord to turn on the system. Usually an orange light means a battery problem.

Toshiba satellite l300 not charging, doesnt work on the power supply


Try removing the battery completely and running it with the power supply connected. If that doesn't work, try borrowing a compatible power supply, or buy a universal one, and try with and without the battery connected.
The problem may be the power supply, in which case the battery won't charge and the laptop won't get any power.

Toshiba satellite L300 freeze when adaptor plug in.


This is a middle pin issue, you will find the laptop doesn't charge either but will power the unit, if the power is connected, the laptop will hang and use reserve resources, if you unplug it, the machines performance will dramatically increase.

replace your power adaptor and all will be fine, i have had the same issue.

Toshiba Satellite L300 shuts down when ac power plugged in


How about this step, try to turn off the laptop itself. Remove the cables and battery just like what you did before, then press and hold the power button for 10 seconds. Then, reinsert the cables and battery on the laptop and then turn on the computer itself. If the laptop restarts, shuts down or freezes with the AC power cables, two things that you should seriously consider. It might be the power cable itself, AC cable port or the circuitry going to the motherboard. And since you have cleaned out the fan and heat sink, you have isolated that problem. Have you plug-in another power cable on your laptop? If yes, then check if it works. Otherwise, the main issue is that the AC port is loose or the circuitry of AC adapter going to the motherboard is not not working. You can re-open the unit and check the circuitry from the AC port going to the motherboard. You may check the circuitry from AC port to the power supply if it is ok. If symptom persist, please contact your local dealer...

My toshiba satellite L300 has no power


Please follow these steps VERY CAREFULLY:

1) Unplug the notebook from the ac adapter (charger power cord)

2) Take off the battery pack on the notebook

3) Once the ac adapter and battery is off the notebook, hold down the power button for 15 seconds

4) After 15 seconds, let go of the power button

5) Now plug in the AC ADAPTER (OR CHARGER POWER CORD) ONLY (DO NOT PUT BACK THE BATTERY PACK)

6) Now press the power button once.

7) If the unit boots, the unit suffered a slight surge

8) If the unit does not boot and remains dead, the unit suffered a severe surge and may be burned out and needs replacing

I hope this helps and let me know how it goes afterwards

Toshiba Satellite L300 Will not start


I have had a this few times... what happens is the Contacts on the Socket for the power supply comes away from the Motherboard. Subsequently, it will not charge, nor power on... & then the battery gets so flat that it stops it all from working... You will have to get it repaired, it is a bit of a mission. & sometimes the damage done to the Motherboard precludes repair. So get a firm "Quote" from a reputable service center/man.
