However, if AC power is connected then the battery is not needed, after all, the PSU can supply enough power to charge the battery AND run the laptop. @Bruce - no more so than any other PC. They use a switchmode PSU which are normally fairly resilient to crappy power.
@Arjan - Windows default power settings are generally to conserve more power at the expense of performance when running on battery. However, if AC power is connected then the battery is not needed, after all, the PSU can supply enough power to charge the battery AND run the laptop. @Bruce - no more so than any other PC.
To start, make sure to use the power adapter that came with the device. Without the battery, the power supply needs to work as the manufacturer intended. Any deviation in the amount of power puts the operation at risk, since there’s no battery backup in the laptop to pick up the slack.
Sure, a desktop computer relies on an external power supply to run, but so does your laptop. Your charger isn’t there to simply charge the battery when it runs low: When you plug your laptop into power, it’s actually running off the power adapter, rather than the charging battery.
This is not the best answer, while UPS will do there are now low voltage (USB) batteries that can supply power to a laptop. Depending on particular battery technology they may be much better suited to frequent deep discharge than the UPS batteries. @Diego, laptops can not take in power over their USB ports.. they supply power to them.
The same for your laptop, if you have removed the battery. The battery works like a UPS (uninterruptible power supply), so you can still use your laptop and turn it off safely. I'd keep it plugged in. Some laptops have a threshold where the AC doesn't charge the battery at all until it drops below a certain point.
