Thank you for contacting AliExpress. This is Eric from AliExpress Case Management Team.
We apologize for the inconvenience that may have caused to you. Due to an unexpected surge in order volume, we are experiencing a backlog of cases. We are doing our best to process your case as soon as possible. Thank you very much for your patience and understanding.
Please kindly understand that our mediation is on the basis that you provided enough evidence for your claim. If you failed to provide sufficient valid evidence eventually, AliExpress Case Management Team could not consider your claim as requested.
Regarding your dispute about the order<63557799794442>, based on the existing evidence, AliExpress can provide you the two following options, and we kindly invite you to choose one of them:
Option 1)  70% refund without returning goods.  [We checked the information and supportive evidence you provided for this dispute, your claim about motherboard can not work problem has been accepted.  According to the verified problem of the order , we can provide this partial refund option. For other claims, we need more evidence to verify the problem. You CAN supplement evidence, we will remediate this dispute once there is more sufficient evidence provided. Please check the helpful link (

Option 2)  Return the goods for a full refund.  (Please kindly note that if there is no agreement that seller pay the returning shipping fee, according to the return policy that seller set for this order, buyer may need to pay for the returning freight; Thus a partial refund as compensation would be a better choice if you would like to keep the product that still has certain value.)
Please let us know your choice or other remarks within 3 calendar days. If you fail to choose or reach an agreement with seller before the deadline, we will close this dispute directly according to the option 1. If the seller provides valid counter evidence as response, we might update options you could choose.
Note: If you have already settled the dispute with seller, please kindly give a response in the complaint center so that we can be informed and follow this dispute based on the settlement.
Thank you in advance for your understanding and great cooperation.
Best regards,

Eric
