How do i ask my mum for a new laptop?

I currently have a lenovo thinkpad chromebook. I've had it for about 3-4 years. It has many dead pixels, it shuts off randomly a lot, the screen freezes, etc. I'm in high school, and it is useless for computer work. It was fine in middle school because everything we did was on the internet, which is not the case now. I can't download any applications (because any apps have to go through google play, which, as we all know, is anything but useful). I don't have any money to buy it myself. How do i askmy mum for a new one

About like that. Nicely.

Well you've put up a pretty good argument already. I'd emphasise how important a laptop is to your education. Adults are pretty keen on good education for their children

Can your family afford it? Could you have it as part of birthday or xmas present?

Can you get a second hand one?

Does your school have a recommended specification you can show your mum?

Do you have any money you can put towards it?

Would any other relative help with buying it?

It nnight be cheaper to ask her to take it sonnewheres to get it fixed
