Introduction

At Seki Gadgets, we pride ourselves on tackling the most challenging electronic device repairs head-on. Recently, we had the opportunity to demonstrate our expertise and determination when a customer sent in an iPad 6 that refused to power on or charge. The owner had previously sought help from various local repair shops, including the Canberra Apple Store, but none were able to revive the device. Frustrated and desperate, the customer turned to us as their last hope.

As the iPad was crucial for the owner’s work and personal life, we understood the urgency of the situation. Our team was determined to get to the bottom of the issue and bring the device back to life.

Comprehensive iPad Diagnostics

Our first step was to conduct a series of comprehensive diagnostic tests. We connected our USB ampmeter and observed a static charging current of 0.8576A, indicating that the device was at least receiving power. However, when we connected the iPad to a PC or Tristar tester, it was not detected, suggesting a deeper board-level issue.

Next, we measured the battery voltage at the terminal, which read 0.486V. We attempted to charge the battery, but it would not accept any voltage. As a precautionary measure, we installed a new battery, but the iPad still showed no signs of life.

At this point, we knew we had to dig deeper into the device’s hardware to pinpoint the underlying problem. We then removed the logic-board from the housing and performed a preliminary microscopic examination of the board to look for any obvious signs of damage which revealed nothing.

Using our state-of-the-art equipment, including a thermal imaging camera, we then injected voltage into the board and found a bad capacitor, C81D1, located adjacent to the U8100 Power Management IC (PMIC). We promptly removed the faulty component and remeasured the VCC_MAIN power line to confirm the short circuit was removed.

With the faulty C81D1 capacitor removed and the iPad logic board repaired, it was time to power on the device. We held our breath as we pressed the power button, hoping our efforts had been successful and to our delight, the iPad 6 booted up and began charging normally. The once-lifeless device had been revived, thanks to the skill and dedication of our team.

FAQ’s

What is the difference between iPad motherboard and iPad logic board?

Apple specifically uses the term “logic board” when referring to the main printed circuit board (PCB) in their devices, including iPads. While “motherboard” is a more generic term used in the context of PCs and other electronic devices, Apple chose to use “logic board” as part of their distinct branding. When discussing the main PCB in an iPad, it is more accurate to use the term “iPad logic board” rather than “iPad motherboard,” as it aligns with Apple’s official terminology.

What would cause an iPad to not turn on or charge?

There are a variety of reasons for an iPad not to turn on, some of which include:

  • Non-genuine or otherwise faulty/damaged charging accessories;
  • Battery issues: If your battery is very old or damaged, it may not charge properly;
  • Software glitches: In rare cases, iOS software issues can prevent your iPad from turning on;
  • Hardware issues: Damage to the USB lightning charging port, internal components, short circuit anywhere on the logic board, water damage caused by corrosion, damaged charging chip or USB protection chip, extreme voltage/temperature fluctuations, flexion damage, drop damaged CPU or power management chip, cold BGA solder joints under chips, technician pry damage near battery connector, and spontaneous board failure.

Can Apple repair my iPad logic board?

Contrary to popular belief, Apple do not repair iPad logic boards. If you present an iPad with a suspected logic board issue at the Apple Store, they will charge an assessment fee to assess the device. In many cases, Apple will charge a premium to completely replace the device for you.

Can my iPad logic board be repaired?

Yes, in many cases, your iPad logic board can be repaired. Some of the common problems we can fix include:

  • No Power: If your iPad won’t turn on or fails to boot, it could be due to a faulty logic board;
  • Stuck on Apple Logo: When your iPad gets stuck on the Apple logo during startup, it may indicate a problem with the logic board;
  • No Touch: If your iPad’s touch screen becomes unresponsive or doesn’t register your inputs accurately, the logic board might be the culprit;
  • No WiFi: A malfunctioning logic board can cause your iPad to lose its WiFi connection or fail to detect available networks;
  • Not Charging: If your iPad won’t charge or experiencesissues with charging, the logic board could be responsible;
  • No Audio: When your iPad experiences issues with sound output or the audio quality is compromised, a faulty logic board might be to blame;
  • No Image: If your iPad’s display shows no image, has distorted graphics, or experiences other visual problems, the logic board may need attention;
  • No Service: When your cellular-enabled iPad displays a “No Service” message or fails to connect to mobile networks, the logic board could be the underlying cause;
  • Random Restarts: If your iPad randomly restarts or experiences frequent crashes, it may point to a problem with the logic board;
  • iTunes Errors: When you encounter iTunes errors while connecting your iPad to a computer, a faulty logic board might be preventing proper communication.

In most cases, a skilled board technician can successfully repair your iPad’s logic board, saving you the cost of purchasing a new device. However, the extent of the damage and the specific issue will determine the feasibility and cost of the repair.
