Re: need hp mini 110-3004tu schematic

does anyone have the schematic?

Re: need hp mini 110-3004tu schematic

A single laptop may have multiple boards from different ODM manufacturers. So many technicians including me don't save schematics by Laptop model number. Please share the board part number and hopefully someone may share the schematic with you.

Re: need hp mini 110-3004tu schematic

This is Flex/Arima 40GAB5400 ODM manufactured board for HP. I don't have this particular schematic. This lap also has a Quanta Annika model board which has schematic available. But the Quanta schematic is vastly different from the Flex board, so no use to you.

This is Flex ODM board. As far as i know, this schematic is not yet available.

what? that's bad.. and what do you mean with FLEX ODM board? please clarify..

ok.. tq for the explaination..

i just need to pin point where is my 5v rail start..
3.3 volt is present and i can switch on my laptop for a temporary of second
and that cause power flash..
and also i cant find my 1.8 volt for the RAM memory vcc.
is it possible my 5volt missing causes 1.8v missing too?

There is a certain sequence in which the power rails are enabled. Although the sequence might be different for platform to platform, usually the 3.3v and 5v came first and the RAM supply secondly. Look for 6.3 volt filter caps. It is less likely for the board to use 6.3 volt rated capacitors anywhere except the 3v - 5v standby section. Tghen you can identify the coils and the Ic which drives them.

Good idea are You should mention your MOBO's code/ID and search first.

How to search: First need login and put * symbol on your word on the beginning and at the End at box search.

there is a lot of 6.3 volt filter caps..any way i'll try one by one

can you give me some dc to dc chip or regulator ic part no. that produce 3 volt and 5 volt dc especially with hp laptop mobo? from there may be i can find it on my mobo

Check U6 with marking CJ=xx, Richtek RT8205A

thank you for your reply

i have found the chip - u6 with marking CJ= BK
but how to count the pin, from where to where?
it has pins on all side

Re: need hp mini 110-3004tu schematic

Here a little info, also you need read datasheet for knowing "How its work".
