For a budget laptop under RM1500 and RM1000, you will have very limited choice in terms of hardware. The most important tip is to avoid buying a second hand, used or refurbished laptop. The laptop could be good for a few months, but ultimately it is very prone to failure. Just stick with a new laptop with an Intel Celeron processor, 128 to 256GB SSD, 4GB to 8GB RAM, and comes with a webcam. That should be sufficient to handle most school work and document work.
