LA-L246P & kbc MEC1515-NM

[mcplslg123]

It'll definitely work if sio is from same donor motherboard..Tested on LA-L243P

Available from Della and authorized sellers. You have to ask if it is clean or D0

Hello, what is the procedure for uploading the service tag?

[Varon23]

We introduce hand after starting the laptop

Thanks Varon23,

After replacing the MEC1515, the laptop will go into "Manufacturing mode Active"
Problem is: Laptop does not save the Service Tag. After saving and restarting laptop the service tag remains empty, moreover the cooling fan is spinning at full capacity (bios problem?)
Bios attached,
TAG service:6QTYKG3
model: Dell 7506 2 IN 1

Please post your bios request in the bios requests sub forum

Does anyone have info how to obtain the firmware for MEC1515-NB (Let's suppose programming is possible) and which size is it?

Here`s some info from the MEC140x datasheet about a crisis recovery .

[SMDFlea]

MEC1515 KSO9 on PVT. What will happen if KSO9 is shorted to gnd at boot i don`t know.

[DanielDacko]

So if I understand correctly, if the chip goes into crisis recovery, it should pull the firmware from the main bios? Although I'm not sure if 14XX have the same principle as 15XX, the datasheet for 1515 seems impossible to find.

Forget what i posted .A blank chip wouldn`t boot without the boot ROM

And when u buy this chips in AliExpress they are always blank I think 😐😐, laptops with this chip are a big headache 😔

[Varon23]

You also need to pay attention to the CPU.

I fixed one Dell. But at the second with the same defect, it turned out that after replacing MEC is still dead. CPU-Bridge was also damaged.

I had a board with burnt 1.8V power chip, i replaced it with SY8388RHC(Kdxxx marking ), and now i have the voltage all across the board , but MCE1515 is getting hot ,laptop dead, soemtimes orange light for charging goes on , so there is no repair? 20V probably went directly to him?

[ferah831208]

U need mec1515 from same donor board I never found the way to purchase the chip original from Dell 😔

[huzo]

Man they made it complicated....I see that the MEC1515 is also hard to replace...
