HP Omen 17 (fm08086 Battery blown fuse)
Hi all, i have this laptop with message of blown fuse.
i already opened the battery and i am assuming that this "FS1" its the fuse. correct me if i am wrong please.
seaching info about this smart fuses i have read somewhere that to check them we do continuity test on the longer side pins. the multimiter beeps on the test.
i have 14.6v and the closest 18650 pins from the cable, but on the actual cabe conector 0V.
can someone help me to test the battery any further... -

Asus GTX 670 dcII burnt mosfet
hi one of mine gtx 670 smoked a little and after dissassembling the card i saw some mosfet burned. (see picture)
with a air station i can take out the bad one and replace it without the change of knock off the pad, or do i need to do something to avoid that?
i cant find identical component, so can i order any "b20 p03" mosfet?
i would appretiate any help you guys can give me.
thanks... -
Re: how to read schematics
yes, it has 2 cameras, cant do any testing with multimeter only? like testing if voltage coming to the camera or something?
i dont have oscilloscope yet...Leave a comment:

Re: how to read schematics
in page 14, we see PP_BATT_VCC and PP_VCC_MAIN on Q4 component.
this are voltage lines, but how do we know their value?
the pp_batt_vcc, i am assuming that is the voltage of the batery but the other one?
i tryed to look in internet for the datasheet of q4 (CSD68803W15) component, but without sucess...
in same page in angelina chip we see some voltage lilnes with pwr2500 or pwr2000, is that important? what does that mean?
thank you very much for your tipsLeave a comment:

Re: how to read schematics
i already asked some questions in my first post.
can i attach schematics in here? no risk of getting banned or something?
first, like i said i've seen macbook laptops schematics where you have power rails, they show you what rails create others, it helps you a lot to follow them and check them...
in other manufacturers schematics and iphones schematics that i've been trying to understand you dont have pages like the ones in macbook's. in this case how we know the voltages in the rails?Leave a comment:

Re: how to read schematics
the manufacturers dont want you to have the schematics in the first place, yet i see them around...
i can only think that this is kind easy to learn and manage, otherwise people would talk about it.
i will make paypal donation to who can help me, and if someone dont want to talk public in topic plz pm meLeave a comment:

how to read schematics
hello,i have seen macbook schematics where they have a page with power rails, this makes life much easyer when it comes to look for the present voltages to identify problems.
but i came across with some other manufacturer boards schematics that dont have this page. in this situations how we know the correct voltage to seek in "test points"
i have iphone 4s schematic as well and it has a page named "test points" it show location and description, but not the correct value that they have to show in order to the device works.
how we... -
