My alien M18 facing fan issue only use for few month still covered by warranty and they sent their technician come and replace the fan and finally caused motherboard faulty, and I ask him why you replace fan can caused motherboard faulty and now pc totally not able to use, he said he also don’t know , what an expert technician, and after that I been informed by Dell CS team that I need to wait for them to order the parts, what? They sent a technician come to my house and make my computer down then go back and ask me to wait and repeat saying sorry serval times , that’s all, what a bad service from Dell. No spearpart ,no emergency action and response, very bad purchase
