Two amber blinks | DELL Technologies
June 19, 2023 - When I try to turn it on, it gives two amber blinks (pauses, blinks twice again, but I'm assuming this is considered just two amber blinks). an empty cup had landed on the pc before it crashed, so I'm wondering if this means the motherboard or something in specific was knocked loose?

Power off computer, remove battery, connect AC adapter,and then power on system again. Please observe any blinking lights. If the blinking lights are still there, power off the system again, remove AC adapter. Press and hold down the power button for 20 seconds to drain any excess static power. Replace battery, connect adapter, and then power on system. Hopefully, there aren't any flashing lights.

It’s possible that the battery has reached the end of its lifespan. Battery Report Check: Create a battery report to check the status of your current battery. Open a Command Prompt window (search for 'cmd' in the Start menu). Type the following command and press Enter: powercfg /batteryreport This will generate a battery report. Locate the report file (usually saved in your user folder) and open it. Compare the Design Capacity value with the Full Charge Capacity value. For a healthy battery, these values should be nearly the same. Battery Replacement: If the tests indicate that your battery is not reaching its full capacity, consider replacing it. Temporary fix/Workaround: Hard Reset Turn off the laptop. Disconnect the AC adapter and remove the battery or simply remove the base cover and disconnect the battery cable. Disconnect all devices such as USB drives, printers, webcams, and media cards (SD/xD). Press and hold the power button for 15 to 20 seconds to drain the residual power. Connect the AC adapter and battery. Turn on the computer. Please contact support by clicking the ‘Get Help Now’ button located at the bottom right corner of the page. The button is marked with a help icon for easy recognition as per the picture below:

Seems to be the motherboard that is the problem just needed confirmation. The light blinks 2,2 I know the power supply works and so do the cables. The form factor is DT and it looks like the motherboard is ATX. Do I have to look for a specific brand or would any brand work fine? All components are stock except the graphics card and I don't plan on changing them unless I have to.
