Forum / HP EliteBook 850 G3

« Last post by Rodja63 on 25 February 2024, 23:23:20 »

Hi i have a broken motherbord with no Dc power supply. I have found a resistor at position Q60002. I have found Schematic diagram ower elitebook 840 g3. I am not Sure if it is exactly the same. Can some one give me info about the value of this resistor. I have check that ic give the supply to the mosfet 23v in the power supply of the bord. I dont now if it possibole to find Correct schematic and bordview file for this cicurit bord. It is 2 resistor in serie to the right of the component name Q60002. I whill send a picture . Thanks. The resistor is to the right side of the text Q60002 where i have the toothpick. I check for this number in the schematic diagram and Could not find this nr.

« Last post by danymogh on 31 January 2024, 10:40:22 »

Hi,

I can't find this part. I've attached the photo.

It's an SOT-23 package IC in Copy code key fobs.
It's an RF receiver IC with fixed frequency 315Mhz.

The marking reads "E8 2246.2"

Hi did some one have a bios file for this laptop in bin format.
The trouble is that the bios have Been hacked of a hacker
What my friend Thell me . The bios is locked and ask for a key to lock upp the bios.
I looking for a new bios file in bin format to program in to a new chip. 20U1.
I have try to take out the back upp battery for the bios and waithing at least One Ouer.
The same trouble.

SMD marking codes / Part No for SOT-26 - 6pin Marking Code 20M2 or 20Y7

« Last post by Rahul on 20 January 2024, 20:42:56 »

I purchased one analog "ON delay Interval" timer about 8-9 months back in which  one 6Pin SMD SOT23-6 component is there on which marking code is as"20M2" after 2-3 months I purchased again same product of different batch no  and the component at that location is having marking code "20Y7" I am unable to get the part No. Please any one HELP.

[/img][/img]Hi i hope some one can give me info about this transistor i belive its a Mosfet. i can see 403MJ. But i dont now what type of transistor it is. its connected directly to the power bord on the dc jack 19 volt. I have look ower internet and cant find this 403MJ for HP mother bord (6050A2892401-MB-A01) I whill send one more picture but this is for HP840.
but they have nearly the same but they use 403Tj for hp 840. And 850G3 they use 403MJ. And i need to now witch transistor for the 850G3 403Mj

SMD marking codes / SOT23-3 SMD CODE 3HU - TL432 or LM432

« Last post by Anthem on 05 December 2023, 16:03:14 »

Add to S-Manual SMD Code

I have a SOT23-3 IC which acts as an LM432 or TL432 Programmable Precision Shunt Regulator

It is marked 3HU with H with a line on top of it. It has the standard 2.5V volt reference and acts exactly like that chip.

Another shunt regulator that acts the same way is the HA17431VLTP from Renasas.

There are a lot of marking codes for this IC reference but this is another one.
