ASUS 主機板 USB Device Over Current Status Detected故障修復
ASUS主機板開機時顯示以下錯誤
USB Device Over Current Status Detected !!
System Will Shut Down After 15 Seconds.
此為USB過載保護偵測，在USB供電發生異常的情況下會啟動該保護
此時無法進入BIOS設定畫面，且會在15秒後自動關機
依序執行以下動作，排除故障原因，直到能正常開機為止:
1.將所有外接USB設備拔除，排除外接設備造成的問題
2.將前置或後置USB面板訊號線從主機板拔除，排除面板故障的問題
3.檢查USB供電Jump是否安裝正常，Pin腳是否有氧化，Jump是否有插緊，排除Jump未安裝或接觸不良的問題
4.更換USB供電方式(若原本使用+5V則改為+5VSB，原本使用+5VSB則改為+5V)，排除供電來源斷路的問題
5.清除BIOS設定資料(將主機板斷電後，拔掉CR2032鋰電池放電)，排除BIOS設定錯誤造成的該問題
6.將主機板從電腦機殼內拆出，使用裸版進行測試，排除機殼變形或有異物造成短路的問題
7.開機後立刻使用電表測量所有USB電壓是否正常(+5V ±5%)，若不正常則會觸發保護，請嘗試更換電源供應器
以下為電子零件故障排除方式:
1.檢查USB針腳是否變形造成短路
2.檢查USB保險絲是否燒毀
3.檢查USB供電相關電阻、電容、電感是否正常，使用電表檢查是否有短路或斷路，零件表面是否有突起或氧化現象

The ASUS motherboard displays the following error upon startup:
USB Device Over Current Status Detected !!
System Will Shut Down After 15 Seconds.
This is a USB overload protection detection. In the event of abnormal USB power supply, this protection will be activated.
At this time, it is not possible to enter the BIOS setup screen, and the system will shut down automatically after 15 seconds.
Perform the following actions sequentially to troubleshoot the issue until the system can boot up normally:
1.Disconnect all external USB devices to eliminate problems caused by external devices.
2.Disconnect the front or rear USB panel signal wires from the motherboard to eliminate panel malfunctions.
3.Check if the USB power supply jumpers are installed correctly, if there is any oxidation on the pins, and if the jumpers are tightly inserted to eliminate problems with jumper installation or poor contact.
4.Change the USB power supply mode (if originally using +5V, change to +5VSB, or if originally using +5VSB, change to +5V) to eliminate power source interruption issues.
5.Clear BIOS settings data (after disconnecting the motherboard from power, remove the CR2032 lithium battery to discharge) to eliminate problems caused by incorrect BIOS settings.
6.Remove the motherboard from the computer case and test it on a bare setup to eliminate issues related to case deformation or foreign objects causing short circuits.
7.After powering on, immediately use a multimeter to measure whether all USB voltages are normal (+5V ±5%). If abnormal, it will trigger protection. Please try to replace the power supply.
The following are methods for troubleshooting electronic component failures:
1.Check if USB pins are deformed causing short circuits.
2.Check if USB fuses are burnt out.
3.Check if the USB power-related resistors, capacitors, and inductors are functioning properly. Use a multimeter to check for short circuits or open circuits, and inspect the components' surfaces for any protrusions or signs of oxidation.
