Re: Dell E7470 with burned MEC5085



Thanks much appreciated, I will look on eBay for a pre-programme chip and take a look for a programmer if it's affordable....

Re: Dell E7470 with burned MEC5085

Yes, the MEC5085 has been replaced, I tried to read the schematic but it's complicated its like deciphering Egyptian hieroglyphs . What power rails power on when you plug in the ac adapter? I know you need 3.3v at the power button but what supplies the 3.3v? I wish I knew someone in my area to explain those schematics. The MEC5085 came from Aliexpress so maybe it's a dud, I bought 2 so I will try the other one just in case!

Schematic for Dell_Latitude_E7470_Compal_LA-C461P_Rev1.0...

Hi everyone, new to the forum and in electronics, I have a Dell E7470 that had a little bit of liquid damage, it shorted out the pin 1 and 2 on the USH connector which are +PWR_SRC_R and +3.3V_ALW2_R, I assume that the +PWR_SRC_R was sent to the +3.3V_ALW2_R and burn the MEC5085, the MEC5085 had 2 rip pads that I fixed. I have changed the USH connector, ribbon cable and the MEC5085-LZY-3, Does the 5085 need to be programmed? The power button does nothing, have no voltage on any of the power inductor except on the main 19v and 13.6v near the battery connector and have 3v not 3.3v at the power button??...
