Toshiba satellite A100 dead. orange steady battery light with mains connected and power button lights shift key and 2 function lights - that's it.

The orange light shows the battery is charging. It will turn green when the battery is fully charged. The white light shows there is power entering the computer.
The usual problem with a computer when there is no response to pressing the power button is that the motherboard has failed requiring the replacement of the motherboard.
If the computer is still under warranty there should be a free motherboard replacement, if not, and you are able to do the replacement, you can find motherboards for sale on various websites. Be aware that motherboard replacement for laptops can be expensive if done by computer repair shops.

Try removing the battery and using the power cord to turn on the system. Usually an orange light means a battery problem.

Try a reset...
1. Remove battery, and disconnect mains adapter.
2. Press and hold down power ON button for 30secs at least.
3. Put the battery back.
4. Plug in mains adapter then Power ON as normal.

From the left,
1, Mains power connected
2, On (glows green when system is on)
3, Battery orange when charging green when fully charged
4, Hard Drive green when accessing
5, Floppy or CD drive activity

Light above keyboard<
1, caps lock
2, arrow mode
3, num lock

The LEDs each indicate something is conected or normal. There is one for hard drive activity, power, battery, and wireless. Blue is good. Orange is bad. First take the charger to a shop to have it checked. If bad replace it. If good the the problem is either battery or the connector on laptop. Since the battery is new it sounds like the connector to me.

orange means stanby in other words energy saving mode

Good day sir, hi, running a laptop without the battery is dangerous, it could damage the laptop, If the laptop is malfunctioning, have it checked by a service repair man, or bring it to your dealer for advice on the service of the power supply.

if one key on the keyboard no longer functions, try an external keyboard. It the external keyboard works normally, replace the built in one

Hi,

you have one of 3 things wrong here.

1:) the battery is dead, and needs to be replaced ( suggest e-bay china seller for cheapest )
2:) the AC adaptor or dc socket on the motherboard is Faulty.
3:) motherboard fault, regarding charging circuit board.

Go for the most cost effective option First. New Battery. Then AC Adaptor. Finally would be motherboard replacement.

Remove the battery pack and power up the laptop from the mains only....then replace the power pack when the machine has booted
