Dell laptop yellow light flashing

Hi jonneymendoza,

I request you to check the Ac adapter status in the BIOS. To go to BIOS restart the system and at Dell logo keep taping the F2 key every two seconds. In the BIOS screen check the status for the Ac Adapter type.
Also I request you to flash BIOS by clicking on the link given below:

//dell.to/Q7ubyv

Please connect the Ac adapter and make sure the Battery has minimum of 15% charge as this needs uninterrupted power supply. Please check if the battery charges 100% after flashing BIOS.
I alsosuggest you to run a test on the battery. Please click on the link to run diagnostics on the battery:

//dell.to/QhZhXV

Under Choose a Diagnostic Type select Component, from the listed components under Make a Selection select Battery and then click on Run Diagnostics. Follow on screen instruction to run the test and reply to this post with the status to assist you further.
