Impossible to Power On a Reworked Razer Blade 14 2022 RZ09-0427

On June 2023 I bought a Blade 14 RZ09-0427 in Taiwan. When I travelled abroad by end of 2023 the machine died very badly. Returning to Taiwan in April 2024, I sent the machine for warranty service on May 2024. They returned the lapto to me saying that motherboard was changed. It wasn't great, but it was usable. The main problem was I had to turn it on 3 or 4 times before it really wakes up. Two weeks ago the machine became worse. I had to turn it on and off 10+ times until it finally boots up. I followed all the procedures found on https://mysupport.razer.com/app/answers/detail/a_id/1798, but after following the latest advice to "recover the machine", it finally went completely dead. Not even 100 on-off cycles can make it turn on. I called technical assistance. They said this is a common problem for this model of Blade 14, unfortunatelly their service and the machine are all out of warranty and that I have to pay USD 1,000+ to change the motherboard once again. Anyone really thinks changing the motherboard once again will solve the problem? Any suggestions, or should I give up this Razer laptop hardware?
