Common Causes After a Factory Reset:
A tablet keeps powering off after a factory reset, even with fresh software,
usually points to a hardware problem, like a failing battery, damaged power button, or motherboard issue, or potentially a persistent malware/firmware corruption that survives a standard reset, indicating deep software damage or a bad component preventing proper function. Check the battery health and power button first, ensure it’s not overheating, and if issues persist after a full charge and reset, a technician is needed.
- Battery Degradation: An old or failing battery can’t provide stable power, causing shutdowns, especially under load, even if it shows a decent charge.
- Power Button Issues: A stuck, jammed, or faulty power button can send continuous signals, making the tablet think it’s being pressed or reset, causing loops or shutdowns.
- Overheating: While less common right after a reset, underlying heat issues or a poor cooling system can trigger shutdowns as a safety measure.
- Corrupted Firmware/Deep Software Glitch: Sometimes, core system files are so damaged they can’t recover even with a factory reset, leading to immediate crashes.
- Hardware Fault: A bad motherboard, loose internal connection, or damaged charging port can cause power instability.
Troubleshooting Steps:
- Charge Fully: Plug it in and charge for a few hours to rule out a simple low-battery issue.
- Inspect Hardware:
- Remove the case and check the power button for stickiness or normal click feel.
- Look for any signs of battery swelling (if removable) or damage.
- Perform a Soft Reset (Force Restart): Hold the power button (and Volume Down, if needed) for 30+ seconds to force a hardware-level restart.
- Boot in Safe Mode (if possible): See if the issue persists without any third-party apps running. If it stays on, a specific app was the culprit (though less likely after a factory reset).
- Check for Overheating: Ensure vents are clear and the device isn’t getting hot during startup.
If it shuts down immediately after the reset, even while showing the setup screen, it’s almost certainly a hardware problem like the battery or power button, requiring professional repair or replacement.
