Products & Quality

What does “renewed” or “refurbished” mean at S.J. Computers?
Renewed products are pre-owned or open-box devices that we have professionally inspected, cleaned, tested, and restored to full working condition. They deliver like-new performance at a significantly lower price than buying new.

Are your computers tested before they are sold?
Yes. Every unit goes through a multi-point inspection and a full functionality test before it is listed, and again before it ships. We only sell hardware we would be confident using ourselves.

Are your products new or used?
We offer both. New items are clearly labeled, and our renewed laptops, desktops, and all-in-one PCs are tested and graded so you know exactly what you are getting.

Warranty & Support

Do your products come with a warranty?
Yes. Eligible products are backed by a 90-day technical warranty covering hardware defects, so you can buy with confidence.

Do you offer technical support?
Absolutely. Every customer receives free lifetime technical support from our 24/7 active support team, so help is always just a call or email away, long after your purchase.

What if my item arrives faulty or stops working?
Contact our support team right away at cs@sjcomputersmn.com or 952 452 8884. If your item is covered, we will arrange a replacement or refund.

Ordering, Payment & Shipping

How do I place an order?
Choose the configuration you want on the product page and click Order Now, then call or email us with the model and options you selected. Our team will confirm availability, pricing, and delivery, and process the order for you.

How do I pay for my order?
Once your order is confirmed, our team will walk you through payment. We accept Apple Pay, credit cards, debit cards, PayPal, and more. All payments are processed securely through trusted third-party providers, and we never store your full card details.

Can I track my order?
Yes. We email you a tracking number the moment your order ships so you can follow it all the way to your door.

How long will my order take to arrive?
Orders are typically processed within 24 working hours and delivered within 3 to 4 business days. You will receive tracking details as soon as your order ships.

Returns

What is your return policy?
If you are not satisfied, you can request a return within 30 days of delivery, provided the item is in its original condition and packaging. See our Refund & Returns Policy for full details.
