No power indicator light on toshiba satellite l450=18h

SOURCE: Toshiba Satellite P200 RT2 won't startup but is

Hook up an external monitor and see if windows loads up, if so it might be a backlight or inverter. if you dont see anything then it might be a hardware failure

SOURCE: Toshiba Satellite L305-S5900. No power indicator light.

sorry there is no fuse that i know of on the satellites it sounds like a motherboard issue see if it can be warranty repaired by the manufacturer

Hmmm...I could help more if I knew which lights were on. Try removing your battery. Then putting it back in, make sure the computer is closed(doesn't matter either way) and charge it. Leave idle (alone) for a few hours. If it still doesn't turn on, call Toshiba, they can elaborate more. You may have to send it in. Probably will cost money.
Sorry I couldn't be more of help. Best of luck

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

Hello.

The most common reasons are the battery, power jack and power adapter/cord.

Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement.

If no change, the power adapter is probably faulty and needs replacement.

Ultimately, your motherboard could be faulty.

If your system is powering, but no display, connect an external monitor to see if the display itself is the problem. If an external monitor works, it is the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim on you rather than a slow degradation the inverter would be indicated.

In either case, a technician in your area should be able to help. Evaluate to see if the repair is cost-effective.

Hope this helps.
