From "Service Promise" to "Responsibility Quagmire": The CMOS Battery Tragedy in R7 7735 Laptop OEM Orders

Introduction: A Promise Worth Its Weight? Or a House of Cards?

In the world of OEM customization and bulk purchasing, supplier promises—especially those regarding product quality and service guarantees—often form the foundation of partnerships. Phrases like "excellent service" and "returns accepted for design defects" can easily lower buyers' guards and create high expectations. However, when product defects hidden behind a "professional" facade come flooding in, when once-confident promises crumble under real-world pressure, buyers may face not just financial losses but a complete collapse of commercial trust. Today, through a deeply personal experience, I'll reveal the "CMOS battery tragedy" surrounding an AMD R7 7735 laptop OEM order and how it dragged me into a four-month "responsibility quagmire."

The Initial "Blueprint": The Supplier's "Sweet Promises"

The story begins with my search for an OEM manufacturer for a batch of laptops. After screening several options, I settled on a supplier offering laptops with AMD R7 7735 processors. During initial negotiations, their sales representatives demonstrated remarkable enthusiasm and professionalism. They visited me to discuss their company's service advantages and emphasized: "We take full responsibility for any design defects in our products and will accept returns!" This assurance gave me great confidence.

The Arrival of "Phantom Failures": Mass "Strike" After Battery Drain

The partnership was established, and the first batch was successfully produced and delivered. However, the real test was just beginning. Initially, only a few customers reported a strange issue: after completely draining the battery, the laptops wouldn't power on when reconnected to AC. They had to remove the back cover and reseat both the RAM and CMOS battery (if present) to boot.

At first, I didn't pay much attention, assuming it was isolated compatibility issues or user error. But as I shipped more R7 7735 laptops, the nightmare began. After selling over 100 units, the "no power after battery drain" problem spread like wildfire. Customer complaints flooded in, and I felt my world collapsing.

The Long, Hopeless Investigation: Futile Efforts From "Screws" to "BIOS"

I immediately organized a troubleshooting team. The supplier's technical team first suggested: "Maybe an internal screw is too long and shorting the hard drive." So we removed the suspected screw and instructed customers to do the same. The problem persisted!

With overwhelming identical failure reports, the supplier's team then claimed: "It might be a BIOS/EC firmware issue requiring updates." We followed their instructions to remotely guide all customers (including unaffected ones) through BIOS/EC flashes. More hassle, but did it work? No! The problem remained stubbornly present.

Supplier's "Evasion Tactics" and My "Bottomless Pit"

Facing such widespread, clearly design- or production-related defects, I invoked their promise and requested returns/refunds. I sent multiple confirmed faulty units to their tech department for inspection.

What followed was a series of baffling "repair" performances:

• First inspection: "Fixed!" I tested returned units - same issue.
• Second inspection: "Really fixed this time!" Still broken.
• Third inspection: "Definitely resolved!" Problem unchanged.

Meanwhile, the sales rep kept saying: "I'm applying for approval, please wait." Endless delays and avoidance.

Truth Revealed: Missing CMOS Battery and Supplier's "Final Betrayal"

After nearly four months of back-and-forth, testing, repairs, and waiting, the supplier's tech department finally delivered an absurd "final diagnosis": these laptops' motherboards lacked CMOS battery slots—they'd forgotten to include them! All system settings (including boot info) relied on the main battery's weak current. Complete drainage caused data loss, preventing normal booting until forced reset via RAM/battery reseating.

The "solution"? Solder CMOS batteries onto all motherboards.

By then, I'd already refunded customers for these "defective" laptops at great financial loss, not to mention time, effort, and reputational damage.

When I confronted them with this "design defect" evidence to honor their promise, they dropped all pretense of professionalism. The sales rep stopped responding, executives avoided me. Their final "solution"? "We'll replace the casings for free. Repackage and resell them."

I was devastated!
