Howdy Ollady, thank you for reaching out with your question about the Samsung Galaxy Book4. Unlike desktop computers, laptops need to be frequently charged since they have an internal battery. If your Samsung PC will not start or turn on, it probably needs a quick charge. On the other hand, if the laptop is not charging or the charger doesn’t seem to be working, or you have a desktop with power issues, then you’ll need to check the power source and some other possible causes. Please take a moment to check out, "Samsung PC does not start, power on, or charge" to help resolve what you have described to be experiencing with your device. Feel free to contact Support afterward if you have any questions for us or if you would like any further assistance. Thank you for being a faithful Samsung customer. - Debra
