please help Hp 15-bs153nt DKL50/CSL52 LA-F761P rev1.0 after 5min FREEZİNG cpu coil It overheats a lot. CPU VOLTAGE 1.8

[msilvap]

have you tried replacing this coil?

[şahan34]

ı have replaced coil and mosfet but same problem ıhave 2 laptops same problem

[msilvap]

I got it
If the coil is overheating, it means that there's an exceeded voltage across it. Do you have the schematics of this laptop on hand? You need to investigate the normal tension for this coil and why the tension is above the normal level.

I searched for a motherboard schematic or boardview but couldn't find one.

Without the schematics, the things will be harder...

CPU VOLTAGE 1.8 !!...Strange value !

I think it's a commun issue in this motherboard , i got same one with same behaviour ( didn't check motherbord yet).

I start to make some research so that what i found , maybe it help :

The Core i3-5005U is an ULV (ultra low voltage)
You can use LA-B843P (Broadwell CPU, i3-5005U is the same) to help you.

I think your cpu core ic is [FONT=Lato]ISL95813 Page 45/46...so
1 - measure all pins resistance
2 - measure cpu coil resistance
3 - measure PCH coil resistance

Intel 5th gen CPUs work with FIVR ( Fully Integrated Voltage Regulator) design, so 1.8Volt for VCCIN is expected, same as with 11th gen CPUs.

Also the resistance to GND should be really high here compared to a "normal" Core value.

That these FIVR power supplies getting pretty hot till some extent is still normal and can only be used as a small indicator at max, not as a clue. More informations need to be collected as advised in previous Post already.

As far as I understand, this is a chronic problem with the motherboard. I will change the processor, I will write the result today, thank you to everyone who is interested here
