Hi,

I have an Acer E5-573G-54AZ and when I start any game the laptop starts toggle power / battery mode every few seconds and then the battery is draining. I clean my laptop regularly from dust and after cleaning it does not happen for a week or two and then it starts happening again even though there is no dust in the cooling system.

I tried to find the answer on the internet but the only thing I found was that there was a possibility that the game was looking for more power than the charger could give, so I bought a stronger 95W charger, but the problem didn't resolve.

I have to mention that the laptop is 5 years old and that started happening back in a year. Battery capacity is 74%. I don't think it's a problem to connectors because everything works normally until the game is on.

Has anyone had a similar problem?


Thanks!

    BEFORE starting any heavy gaming loads, the battery must be near 100% charged and charger plugged in to extend playing times. However, even a 95watt charger can't keep up with the load of both charging a low battery and supplying power to the CPU/GPU at the same time. While the battery capacity might be 74%, an older battery usually loses its ability to deliver this charge capacity (ampere-hours) fast enough (eg. amperes needed) under high load and results in power throttling.

    Hi JackE,

    so you think it is battery even capacity is not that bad? Actually the charger is always plugged into the laptop and the battery is always 100% before I turn on the game.

    Yes, the "charge" capacity seems fair. Charge capacity is measured by "amp-hr" or "milliamp-hr" capacity. But an important parameter under heavy gaming loads is how quickly this amp-hr capacity can emptied or discharged. This is measured by "amps". The battery health meter only  checks amp-hr capacity. Not amps. If this is the original battery more than 5 years old, then it may no longer be able to empty its charge capacity quickly enough to run the CPU/GPU at full speed.  New replacement batteries are about $35 USD  Jack E/NJ
