If it's not the battery, you could check the power supply, BIOS, or operating system settings that might be the root of the problem. However, you'll have better luck if you read and research the errors the computer gives you. Saying that the computer "shows error" is like saying that you have an illness that "shows symptom." Always read and Google all error messages, and share that information with anyone you want to help you! Finally, this website is not a technical support venue. It is a forum for discussion of tech business news and happenings. You should probably talk to your laptop's manufacturer, or a technically inclined friend, or maybe ChatGPT.
