Toshiba Satellite L40-15G blinking leds no power up.

This is the problem, the laptop wont power up, e remove everything, memory, battery, all of that, 30 seconds pressing power button, to descharge, and nothing.

Only blinks the power (green) led - and the battery (orange) led, blink, blink, non stop blinking, non top really.

When i connect the ac adapter only the green led and orange led shows, after few seconds, start blinking, non stop blink...

What can i do???

I have universial ac adapter to charger, and wont solve the problem...

Help, please, urgent.

Regards.

And do you hear start up sounds? like windows start up ? And do you see the LED screen gets bright or stays black. if Black and no sound then it might be as well as broken parts in your laptop. If you hear sound but nothing visual then screen problem.

You need to put the cmos battery back into the motherboard. However, it might not make any difference, if the cmos battery has be removed for more than 3 days the cmos chip is possibly dead and the bios will no longer show. It might be possible to replace the cmos chip.

A universal power adapter, although readily available is not the actual voltage/amp required by the laptop, refer under the laptop for the exact v/a required. Any deviation from the exact adapter required will cause issues with the battery, capacitors and other components.

If the cmos chip is not dead then it might be the laptop battery and a replacement might fix your issues however, you would need to acquire the correct adapter for the laptop so that the issue does not re-occur.

TenPc, you are right, i just have to say, many thanks for your repply.

Here the thing:

First - i don´t know why, they take the battery out of mainboard, realy don´t...

Second- i try connect the ac adapter universial, to see what appens, but i do think, the original is ok.

in the end, can you confirm is the CMOS battery stay out for few days, can kill the Bios, and then all motherboard can no longer gonna switch up again?

Please, confirm that.

Regards TenPC.


Guanhao, i say if the scrren or any kind o beeps, i can say to you, the screen or beeps, never appens, just the leds show up, the green one (power), and the orange blinks (battery).

Thats all it appens.

Regards.

The bios date/time to always be configured is that the bios is not being powered by neither the cmos battery nor the laptop battery. You need to replcae the cmos battery with a new one.

It does take quite a while before the CMOS does die, with a laptop cmos, it could be as long a 90 days without a cmos battery. When the cmos chip is held by the manufacturer prior to being set in a motherboard, the chip is put into a bedding that powers the chip and is not just thrown into a storage box ready fur use.

You are best to take the laptop to a service repaiir shop for expertise attention, there really is not a lot you can do unless you can replace the cmos battery yourself, without damaging the laptop in the process.
