something to try - a long shot but who knows...

Remove mains power connection - and the (main) battery.

Press and hold the on/off button for about a minute or so and then release it.

Re-install battery then switch on asper normal, and see if the problem persists (or not).

Reconnect power adapter/charger and try that way too.

Are you sure the mains charger/adapter is OK? They can and do fail... Usually the cable goes intermittent at the point where cable comes out of the charger/adapter block assembly; and also at the mini connector plug end (the one that goes into the laptop).

Equally common is simple failure of tha adapter/charger - due to age and/or

Are you sure your battery does charge up?

Do you have the possibility of borrowing (to test with) a known good charger/adapter?

Are you sure nothing happens other than the light coming on?
If you wait, does the light eventually go out? That would mean
Windows loads but either your screen or your video processor
died so you can't see anything.

Are you sure the orange light is the hard drive activity indicator,
not a power indicator? There are 2 power indicator lights on the
HP laptop I'm typing on. One is beside the power connector for
the charger, the other is on the opposite side of the laptop, beside
the HD indicator light. The first light has a different color, flashes,
or is off depending on whether the computer is plugged in and
charging, plugged in and fully charged, or unplugged. The other
power light is on when the computer is on. You should check the
manual for your laptop if you aren't sure.

If you are right that it is the HD indicator, and the screen and video
processor are okay, then the problem may be in the drive. Does
anything at all display on the screen? Can you get into the BIOS?
Does the instruction for how to start the BIOS setup program display
briefly? If nothing displays, then the problem is not in the hard drive.
Screen, video processor, motherboard, CPU, or power supply are
the possibilities.

Here is one possible solution you can try:

Remove the laptop from the power source and remove the battery from the unit as well.

Long press the power button and release.

Now, without reinstalling the battery to the laptop, simply connect the unit with a power source using the charger, and start the laptop.

If it starts, give it time to boot fully to reach the desktop page.

Once the boot is complete and the device is stable, shutdown like you normally would.

Switch off power and remove the charger.

Next, you can put the battery back in its place, and start the laptop.

Hopefully, it should work fine now.
