Overview of the iPad Pro 12.9 2nd Generation Released in 2017, the Apple iPad Pro 12.9 2nd Gen marked a major milestone for professional tablets. Powered by the A10X Fusion chip and introducing Apple's 120Hz ProMotion display technology, this model provided artists, designers, and power users with unprecedented fluid rendering and expansive screen real estate. It retains the physical home button with integrated Touch ID beneath its expansive front glass while delivering bright color depth and low Apple Pencil latency. Despite being several generations behind current Apple silicon, the 2nd Generation 12.9-inch iPad Pro remains a favorite daily driver for thousands of users who value its generous canvas size and strong performance. However, because of its large physical footprint and aging hardware components, maintaining this tablet often requires professional maintenance when physical accidents occur or internal batteries reach the end of their functional lifespans. Typical User Base and Daily Workloads Owners of the iPad Pro 12.9 2nd Gen are typically creative professionals, illustrators, students, digital note-takers, and business operators who rely on multi-app Split View and pencil-based workflows. Because this device is frequently moved between desks, studio stands, backpacks, and field sites, it undergoes continuous physical handling. The heavy daily cycle of high-brightness display usage, digital drawing, and continuous charging places steady demand on internal sub-assemblies. Over years of active operation, wear on mechanical ports, reduced battery chemistry efficiency, and accidental drops are very common across this user base. Common Failure Points and Structural Vulnerabilities Due to the immense surface area of the 12.9-inch glass front panel, structural leverage makes this specific iPad model particularly vulnerable to impact damage. A drop onto a corner or edge frequently spreads spiderweb fractures across the entire glass sheet. Because the 2nd Gen Pro utilizes a fully laminated display architecture—where the top glass digitizer is glued directly to the Retina LCD underneath—cracks in the outer layer generally require replacing the entire fused screen assembly to preserve visual quality and touch sensitivity. Internal battery degradation is another frequent issue. As the internal dual-cell battery completes hundreds of charge cycles, users notice short battery runtime, thermal buildup during routine drawing, unexpected device shutdowns at medium power percentages, or screen lifting caused by swollen battery cells. Additionally, the bottom Lightning charging port experiences significant physical stress from cable tension while using the device while plugged in. Other common hardware issues include sticky or failing volume and power flex cables, degraded quad-speaker output, faulty camera modules, and logic board power rail shorts resulting from fluid contact or low-quality charging bricks. Comprehensive Repair Options at LML Repair At LML Repair, we provide targeted repair services designed specifically for the construction of the iPad Pro 12.9 2nd Gen: Screen Replacement: We replace broken or unresponsive front panels using top-grade laminated assemblies. This restores full 120Hz ProMotion refresh rates, precise touch digitizing, and original Apple Pencil pressure sensitivity. Battery Replacement: Our technicians safely decouple the bonded front glass, remove worn or expanding lithium-ion cells, and install fresh, high-capacity replacement batteries to restore reliable all-day performance. Charging Port and Connector Repair: If your Lightning cable fits loosely or fails to transfer power, we clean or replace the internal charging flex harness to ensure stable current delivery and data syncing. Camera and Speaker Restoration: If your front FaceTime camera, 12MP rear camera, rear lens glass, or four-channel speaker array stops working or distorts sound, we replace individual components to return your media capability to factory standards. Button and Sensor Flex Repairs: We service failed internal tactile switches for the home button assembly, volume toggles, and power key, ensuring crisp physical feedback and correct signal routing. Logic Board and Water Damage Repair: For tablets suffering from liquid spills or power management failure, our bench experts perform ultrasonic cleaning, micro-soldering, and trace repair to resolve complex board-level faults. Data Recovery & Transfer: When a tablet suffers catastrophic physical or board damage, our diagnostic team focuses on retrieving critical artwork, documents, and personal photos safely. Model Identification and Component Hardware Nuances Accurately matching parts for the iPad Pro 12.9 2nd Gen is critical during servicing. This model comes in two main variants: Model A1670 for Wi-Fi only and Model A1671 for Wi-Fi + Cellular, both etched on the lower aluminum back cover. While screen assemblies are broadly compatible across both variants, cellular models feature dedicated internal antenna routing and baseband hardware that must be handled with care during disassembly. A crucial hardware factor on the 2nd Generation iPad Pro is the Touch ID home button module. The biometric security chip inside the original home button is cryptographically paired to the tablet's original logic board at the factory. If this ribbon cable is torn during a screen installation, biometric Touch ID functions are lost permanently. At LML Repair, our technicians take extra care to carefully transfer your original paired home button assembly onto the new display framework, ensuring Touch ID functionality remains completely operational whenever possible. DIY Repair Challenges vs Professional Servicing While LML Repair supports the self-repair community by offering detailed diagnostic advice and DIY guidance, repairing an iPad Pro 12.9 2nd Gen requires advanced tools and patience. The broad glass front is held down by strong perimeter adhesive. Removing the screen requires uniform heating and precise prying tools; excessive force easily cracks the glass further or damages delicate ambient light sensors and screen flex ribbons located near the top and bottom borders. Furthermore, the battery in this model is glued directly above delicate logic board traces. Prying against the battery without proper solvent and wide plastic spudgers risks puncturing the lithium pack or ripping off critical surface-mount components from the motherboard. By letting LML Repair handle your service, you avoid the risks of permanent logic board ruin, torn ribbon cables, or personal safety hazards associated with punctured battery cells. Selecting the Proper Repair Service To choose the correct service on our page, examine the specific symptoms your device exhibits. If the glass is shattered but the screen displays clear images and responds to touch, or if the touch panel misses inputs, a Screen Replacement will fix both issues because the glass and LCD are built as a single unified part. If your tablet powers down without warning or shows a bulging display, select Battery Replacement. If charging requires angling the cord in a specific position, choose Charging Port Repair. If your device was exposed to liquid or refuses to turn on entirely, selecting our Diagnostic and Water Damage Evaluation is the best first step.
