Even if you know where the ferrite bead component is, the value and its specs you might not know. The symptom you said in question seems that heat issue or board level failed.

If you mean the ferrite bead on the cable from the power brick (AC adapter), it can't have any such influence. Its only use is to stop high-frequency interference to/from the laptop through the power cable.

What is the charge status of the battery?
Can you try the power brick with another laptop (it could be bad)?
