Hi, my ASUS T100TA won’t power on, When plugged in, LED slowly blinks orange/amber.
I hard discharged the battery, removed the tape on the POWER button and plugged it in and… LED still slowly blinks orange/amber.

When the LED is green the battery charge is between 95% and 100% and the AC power is on. The orange/amber LED indicates that the battery power is below 95%, and the AC power is on. Without the charger plugged in an orange/amber blinking shows the battery charge is below 10% and needs a charge.
However, if your laptop battery percentage is above 10% and the LED keeps blinking orange/amber it may mean the battery needs replacing.
Lithium-ion cells age the moment they leave the factory, plus the ~500 cycles they can do (to 80% capacity considered EOL). That means the batteries in the long termed stored laptop will be degraded, even without having been cycled or used.

Oh, also, I found out that I didn’t properly hard discharge the battery. When I left it for a night, the battery was completely dead and when I removed the tape that was holding the POWER button to the on position and I plugged in, this time the light was still orange/amber but was no longer slowly blinking. Now after this, the computer now worked. I will remplace the battery when BatteryBar shows a high percentage of battery degradation.
But still, thanks.
Update: BatteryBar is showing 84% battery health (I think) but it’s not the worst! My iPad 6th Gen, which I got it on Christmas 2018, has 1931 battery cycles which equals only 61% battery health!!!
For a 5 year old computer 84% is pretty good.battery health.
It’s because i rarely use it compared to my iPad. I always plug the charger when using it. I switched to a pretty old HP Spectre Pro x360 G2 laptop, it has a mostly brand new battery, since it was never used for some years.

NOTE: My laptop/tablet was actually a ASUS Transformer T102HA. But since it didn’t exist it the repair tutorials, I picked the device that was the closest to my computer. Instead of showing a green light, it shows a white one. My computer is 5 years old and 6.6% of my computer’s battery is degraded, which means it can only hold 29 138mWh instead of the rated 31 200mWh. But is 93.4% battery health low? When my battery needs remplacing, maybe I will do a tutorial about how to replace a battery of a T102HA.
