Toshiba a205 I let the battery go dead now all it will do is flash the blue light with the cord symbol what's that mean?

Check AC power cord, use a different one, also plug into different outlet. If that doesn't work power switch is bad. Or something else is wrong.

Maybe the battery is dead. Remove the power cord and see if you can work on the laptop on battery power for any length of time. if it goes off quickly.

A good power cord will not charge a dead battery. Batteries only have a useful life, then they have to be replaced.

If it does the same thing w/ the battery removed and just on AC, it's a power regulator problem on the motherboard. If it works with the battery out, the battery is dead and you need a new one.

Try deteach your battery and plug in power cord .. if notebook don't start it is something wrong with recharger.

Hello.

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

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.

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

If you are knowledgeable, remove the heatsink and apply new thermal paste.

But, it certainly could be the mobo.

Hope this helps.

Most laptop battery can be normal used in 400-500 charge and discharge cycles, in another word, a laptop battery should be normal in 2 year.

I think you may need a new power supply, check this to make sure it is working OK, If this isn't working then the battery will not charge, and give symptoms you describe.

Remove battery and power

Remove memory in lower socket, the one on the system board and try reboot with just power cord. May have bad socket

clear the bios by removing the small battery on the mainboard for 10 hours.the power on

the laptop overheated and the motherboard is damaged and need replaced
