Using Laptop with only Adaptor power

[PoinardKh]

Hello,

I use my laptop throughout the day, and it often requires frequent charging. Sometimes, I run demanding tasks that consume a lot of battery power. Additionally, charging the battery generates a noticeable amount of heat.

Since I always have access to a power socket while using my laptop, I wonder if there's a way to use the laptop directly with adapter power, bypassing the battery. Is this possible?

Thank you for your assistance!

Hi:

You should be able to do that, but you would have to take the notebook apart and disconnect/remove the battery.

The disadvantage to this is that every time you shut down the notebook, when you restart it, you will get a CMOS 502 checksum error that you will have to clear and then set the time and date and any BIOS settings you may have changed from the default values.

That is because the main battery also serves as the Real Time Clock (RTC) battery, also known as a CMOS battery to maintain the BIOS and system clock settings in older notebooks that normally have external batteries.

You may want to give this a lot of thought before proceeding because it is not easy to take the notebook apart.

Hello,

Thank you for your detailed response!

I should mention that my laptop is still under warranty, so I’m not comfortable disassembling it myself. Therefore, I was wondering if there’s any other way to achieve this.

Also, if I keep the laptop plugged in and use it while charging, will the system automatically manage this situation without any issues? Are there any additional settings or adjustments I need to make to prevent any potential problems, such as battery wear or overheating?

I appreciate your advice and guidance!

Thank you again.

Your very welcome.

Unfortunately, there isn't any other way to bypass having the battery connected.

Note that when the battery reaches 100% charge, the power adapter quits charging the battery.

Yes, the battery is subject to heating up due to the other components working (processor, graphics, memory), and leaving the battery in a constant 100% charge state may lead to battery swelling.

That means not to leave the notebook plugged in to A/C power 24/7/365.

The only other suggestion I can offer would be to read the info at the link below for how to get the most life out of your notebook's battery:
