(High score reward) HP replaced an old motherboard for me within three bags.

It is impossible for the landlord to change the new motherboard. I work after sales. This has been the case for many years, and good products are also guaranteed. If I'm lucky, there won't be any problems! The warranty will not be returned to the factory, and will be distributed by the dealer himself! It is suggested that we continue to call 123 15 to make a complaint, or propose to replace the motherboard at our own expense (3,000 yuan of evidence, such as recording, audio and video, advance payment, etc. ) and then take the evidence to the industry and commerce and price bureau to complain. This method is the most effective, someone will contact you soon!
