Re: no power

Can you just clarify how much you are certain the adapter is OK......did you you for argument sake try another adapter. The battery might be poked or that adapter not going. I know laptops may get sentimental (so to speak)but they dont just shut down for no reasons technically unless the battery is stuffed or there is NO power to the unit. Thats why the LEDS are not lighting up?

My toshiba satellite pro doesn't work , even with charger in , it doesn't turn on , its like all the power is gone :o ?

You may have a bad DC connection:

Symptoms of a broken power jack
1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning

If your laptop is out of warranty, then you can fix the problem by resoldering DC-IN jack on the system board. If it

I have a toshiba LT a205; the LED flashes 6x; what does that mean? the psu is rated at 19vdc, and puts out 18.5 vdc. The end of the power connector that goes to the mb only has 0.5 vdc on it, so I'm...

19volts is a nominal value. The AC Adapter will be fine from 18 volts up to 20volts because the power unit on the motherboard regulates the voltages very accurately.
You say you only have 0,5volts on the Mother Board power input. There's your fault. Between the Mother Board socket and the AC Adapter.
Replace the AC Adapter or Laptop Connection lead if you mean there is 0.5volts actually on the Mother Board but full oiutput from the Adapter.

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...

Toshiba a215-s5837 problem, ac light only flashes

You may have a bad battery. Many times laptops will not work if the battery is faulty. The first step would be to replace the battery with a new one.

Second Step: If the battery is working, then you may have a faulty AC power supply. It may be enough power being brought to power up the LCD light, but not the computer.

Third Step: Yoru mother board circuitry could be bad in the sense that some circuits are broken or the power conduit is not supplying the power to the rest of the circuits on the board.

If you are not a professional and able to troubleshoot in this manner after testing the batter and AC power supply, then I would suggest taking the laptop to a store for them to test the circuitry flow of the mother board.

Toshiba satellite m35-s456 my computer lights come on but it will not boot up?

The same thing happened to me today. I think it is the power supply connection to the mother board. I had to replace the motherboard 2 yrs ago with the same symptoms. I can reboot the computer 20 times and once the laptop will boot-up OK. But most of the time the power button will come one but the screen is blank. I'm not sure if I am going to get a new laptop or just replace the motherboard...again...
