Convincing parents to buy me a laptop

I used to actually have a laptop with a graphics card back in the day an gtx 920 but one day it's screen broke!, my father made me wait 6 months till eid, and told me "gimme your money, I'll get your screen fixed, I'll return it to you later" he took 8k from me and 2k from my sister who broke the screen, and put some money on the screen himself, (but he never returned the money) fast forward a few months he went to Dubai on a business trip, I had asked for some extra ram, he did get me that, but only 1 stick instead of 2, and got me the laptop I'm typing this on, he was like "LOOK I GOT YOU A NEW LAPTOP" and I just looked at it and started to think about it, I don't think this is a good laptop, and in fact it wasn't a dell latitude e7470 with no graphics card and 8gb's of the lowest quality ram and a 256 GB nvme ssd, I didn't say anything at the moment at just went with the flow fast forward a few days my uncle(mamou) comes over and was like this laptop can hardly run 4 chrome tabs what do expect from it, my father tried to reason with him, so my uncle stepped back from the argument. My father told me that this laptop is for work only do not use it for other purposes like it's some really high quality quantum computer, and once while I was watching a YouTube video on it just for entertainment he kicked me of the laptop and took it from me but it didn't really matter because I had a better laptop lying around, but he eventually returned the laptop to me, warning me again, but once my old laptop had a seizure (short circuit) and the motherboard got damaged,which was blamed on me. fast forward my dad sent my old laptop to my uncle(chachou) to get fixed but my uncle never really got it fixed and told my dad that it can't be fixed, but I knew he didn't even try and was using it's parts, I caught him in the act of giving my aunt my hard drive (ssd), because my aunt needed a laptop for her "teaching career" and the one she had was to old so my uncle gave her an upgrade new ssd, ram, and an internet card, and later on when I was at my uncles house I requested my father to tell him to give me my hard drive(aka the time I caught him in the act), since he was like I can't find the hard drive maybe later, but my cousin told me this "mama has your hard drive internet card and ram, she doesn't know but uncle told me" which he proved since when I got my hard drive it wasn't even formatted and since due to an past incident my admin privileges were revoked (my sister managed to corrupt windows while I was studying for my exams and they thought it was me but I cracked the password using an exploit later on) since the hard drive was not formatted I just booted into it and created a bootable usb for Linux mint and installed it on the external hard drive,

But now after all this time I need a new laptop for my studies I can not play games, I can not do any proper research, I can not talk to my friends because the laptops sound card has a problem but I'm afraid due to all this my father might not get me an new laptop (and now I also develop game but I need a better laptop/PC to advance) because he probably doesn't trust me and if I ask him anything he's like we spend a lot of money on your education be thankful. and now how do I convince him to buy me a new laptop?
