The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
configurable for operating as either a Hybrid Power Boost (HPB)
charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
4-cell batteries. Both configurations allow the battery to work with
the adapter together to supply the system load when it exceeds
the adapter capability, referred to as system Turbo mode. HPB
charger configuration reverse-boosts battery energy to the system
bus to help the adapter provide the system power in Turbo mode.

I have an RC radio handset(Taranis QX7) which doesn't have internal battery charger which means I had to remove the battery every time I needed to charge it.

So the battery is backfeeding the charger and being drained.

The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.
Windows also shows ''Plugged in'' when charger is not connected.
This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
If I let battery run out and say it has 3% Windows will... -
Hi, I have a Dell Inspiron 7567 LA-D993P that I've just got running.
There was corrosion around PU1503 which shorted PC1518 & blew PL1504. (Reference pictures attached)
I've replaced PC1518 & PL1504 & the laptop is now running however I now have another issue.
Here are the tested scenarios:
1. With the laptop running on battery, I plug in the 150W charger & the charger shuts off (no LED, protection mode) but the laptop remains running on battery.
2. With the laptop off, plug in charger (LED says on) & the front charging...
