Lenovo Ideapad Slim 3 Keeps Shutting Down Unexpectedly After Less Than a Year

I purchased a Lenovo Ideapad Slim 3 about 9-10 months back, primarily for my studies, since I don't engage in gaming or use demanding software. Unfortunately, over the last month or two, the laptop has been shutting down without warning. When I power it back on, it occasionally shuts off again in under a minute. Sometimes, error messages show up on the screen after a restart. This problem has created significant challenges in using the laptop for essential activities such as participating in online classes or completing assignments. Given that the device is still quite new and has only been utilised for studying, I anticipate a suitable resolution or repair. I would appreciate your guidance on the steps I need to take to resolve this issue promptly.
