Hi,
I have an Alienware laptop that is getting an error recognising the battery and will not charge it.
Where I should get 3.3v to the battery I'm getting closer to 0.5v - when on charge, I have found a mosfet emb04n03 that is taking 19v but only giving out 15v there are two others near that are taking 19v and output 19v same model mosfet. The suspect mosfet also shows different resistance readings across the gate and source.
I have ordered some emb04n03 from China but the expected date is sometime in June so I was hoping to fit an alternative but able to find a similar mosfet to values below
Vdss 30v
Rdson 4.0
Id 75a
Pd 50w
Can anybody give me an idea of what specs are a must and what might be ok if different.
Thanks for any advice.
