Aspire 5732z battery charges but will not turn on

I recently changed the USB ports on my laptop. Once I reassembled the laptop, it would show signs of charging the battery (via the LED light) but when I tried to turn it on, the LED charging light turned off and nothing happened. I would have to unplug the battery and put it back in again for the charging LED light to come back on.

One thing I didn’t do when reassembling was to replace the thermal past on the CPU. Would this cause the laptop to not turn on? Otherwise, nothing seems damaged on the motherboard or any cables I unplugged and replugged. Any ideas?

Thank you,

It sounds like you’re experiencing issues with your Acer Aspire 5732z after changing the USB ports. While the thermal paste on the CPU generally affects the cooling performance rather than the ability to power on, there are a few things you can check and try to troubleshoot the problem:

  1. Recheck Connections:
    • Ensure that all the connections, especially those related to the power button, motherboard, and battery, are securely and correctly reconnected. A loose connection might be causing the issue.
  2. Battery and Power Adapter:
    • Make sure the battery is properly seated and connected. Try turning on the laptop with the battery removed and only using the power adapter. If it turns on, the issue might be related to the battery.
  3. Reset Power:
    • Disconnect the power adapter and remove the battery.
    • Hold down the power button for about 15-20 seconds to discharge any residual power.
    • Reconnect the battery and power adapter, then try turning on the laptop.
  4. Inspect for Damage:
    • Carefully inspect the motherboard, cables, and components around the area where you worked. Look for any signs of damage, loose connections, or misplaced components.
  5. BIOS/CMOS Reset:
    • If the laptop has a removable CMOS battery, you can try removing it for a few minutes and then putting it back. This will reset the BIOS settings. Ensure the laptop is powered off and unplugged before attempting this.
  6. Check Power Button:
    • Make sure the power button itself is functioning correctly. If it’s damaged or not making proper contact, it might prevent the laptop from turning on.
  7. Thermal Paste (Optional):
    • While the thermal paste generally doesn’t affect the ability to power on, it’s good practice to apply fresh thermal paste when you disassemble and reassemble a laptop. Over time, thermal paste can degrade, impacting heat dissipation.
  8. Professional Inspection:
    • If the issue persists and you’re unable to identify the problem, it might be beneficial to take the laptop to a professional technician for a detailed inspection. They can identify any underlying issues that might be causing the problem.

Remember to handle all components with care, and if you’re not comfortable with laptop disassembly, seeking professional assistance is advisable.
