Your inverter is failing. You can test this by trying it with an external monitor, if you get a picture, then this is the problem. If it still does not work, the issue is with the graphics chip on the motherboard

My 1501 Dell Inspiron turns on but I have a blank black screen. The only light that shows is the power light on the upper right side of the laptop.


Power getting to the laptop. Try first to see if this will give a screen image on an external monitor, listen for the sound of the cpu fan, hard drive and DVD rom drives clicking, see if the DVD rom drive will open if pressed.

Then remove battery and AC adaptor, press the power button for 30 secs, refit mains only and try this on mains supply (no battery)

If this fails to boot, check the light on the ac adaptor is a steady green, flashing green indicates power is not fully reaching the laptop (motherboard problems)

If it is steady and the LED power light on the laptop is steady, suspect the DC jack socket. If this feels loose or sloppy, it will need replacing, depending on the type fitted, it may be soldered onto the board, or a wired connector, which sometimes goes bad.

After that, I'd suggest that a capacitor has gone on the actual motherboard and you will need to strip the laptop to check it.

It works good on battery but when AC adaptor is plug in the laptop cuts out and restart by itself.


Problem description: The laptop shuts off when AC power adapter is plugged in. The laptop works fine on battery power but as soon as you connect it to AC adapter, the laptop turns off.
Possible cause: 1. Power adapter failure.
2. Motherboard failure.
Possible troubleshooting steps and repair solution: First of all, test the power adapter. Make sure the adapter outputs correct voltage. It's possible that the output voltage is not correct and the laptop shuts down to prevent the damage. Test your laptop with another known good power adapter.

If the problem still exists, even after replacing the adapter, most likely it's the motherboard failure. Replace the motherboard.

Laptop won't switch on although blue power light on is showing power is getting to the machine


Check the power adaptor led is not flashing. Flashing Adaptor LED indicates fault with laptop charging circuit / powerboard

If it will not boot on battery, and you know the adaptor to be good, the issue lies with the motherboard.
Sometimes, removing the battery, and unplugging, pressing the power button and holding it for 30 secs, replacing the adaptor only will allow it to boot up, but this will only work if the motherboard is not damaged r the CPU fan has not failed.

Toshiba laptop will not turn on, screen is completely black


Don't pay attention to your uncle. I had the same problem. Blue ring, power lights on. Sometimes the laptop would come up after a few minutes and then would freeze. It is a power problem. The AC jack may be broken and, most likely, you need to get the MAX1632A power controller (a 40-48 pin black IC next to the AC jack) resoldered too (get someone qualified to do it, with the right soldering station for surface mount work).

Toshiba Satellite 1405 - Power problem


Hi Don

Although symptom is showing that AC Adaptor is not working as its not providing power to the unit. I will suggest you to perform some basic troubleshooting steps. Check if outlet is working if not check with known working outlet. If you have a multimeter you can the output of the AC adaptor.

Also you can perform full power cycle and component discharge. Take the battery out and disconnect the AC adaptor press the power button and hold about 7 seconds. After that put the AC adaptor in and test again.

If issue persist take to nearest Service center check with known working AC adaptor. After that I believe you will figure out the best solution.

Good Luck
