UMA enable AX1J Hp

[gcomputers]

Hi this is a machine that i reballed Gpu after 1year and now its come again with black screen .
i need some help to disable gpu and to enable UMA but i dont know what resistor to replace ?
need to remove R463 and to replace on R242 , and to remove coil of gpu exact? any suggestion please ?

Re: UMA enable AX1J Hp

i make i little reflow and this is only ATI HD 6370 . so this model can be UMA or not because i dont see intel graphic on device manager

Re: UMA enable AX1J Hp

Cpu is i3 .
Any suggestion i tried to remove coil and to replace some resistor but no screen.

Re: UMA enable AX1J Hp

do you know what is

Board ID5: For idenify UMA and DIS
Board ID4: For idenify FF and DF

there are two tables page 10 and page 11

can you make pictures of that area

Re: UMA enable AX1J Hp

These are the pictures for some resistor like R242,R243,R464,R463 .
Also i make some experiments :
removed PU11 but again coil of gpu have 1.1v.

i did not try this, only found on web
good luck

Re: UMA enable AX1J Hp

if someone is interested in it, i took some pictures of 2 motherboards, one with a discrete VGA amd, one with an intel gpu enabled


you can see the pictures them in the attached archive

not working.. the o.s. only recognize the amd radeon, and not the intel hd..

[kropotkin]

Re: UMA enable AX1J Hp

Have this board on hands, will try. Can anyone help with boardview for this MB with BGA CPU, not with socket one?

[caspian]

Re: UMA enable AX1J Hp

you should mention the mainboard model and revision.
It is supposed to be requested in the schematics subforum.

Re: UMA enable AX1J Hp

Checked recently, everything is working

This chinese triptich contains information which can not be found on on schematics and boardview, because both available only for socked CPU type. The rest is the same for both boards. So, simplified instruction to get image on integrated LCD, excepting CPU-side signals which are on "triptich" already:

0) Remove ATI
1) add R290, R305, R315 (for nominals refer to schematics)
2) add Y2 (25MHz), add C731, C732, R492 (these four can be easily found around any South Bridge on old dead AMD boards), remove R510.
3) move R462 to R463; R292 to R301; R299 to R318
4) move group of doubled resistors RP2,4,6,8, to RP3,5,7,9; RP10,12,14,15 to RP11,13,16,17; RP0 to RP1
5) move three single 0R resistors R79,80,125 to R309, 310, 311
6) Points between 2-nd and 3-rd pictures (where written JUMP) must be connected with thick copper wire.

CRT and HDMI function needs further rearrangements according to schematics and boardview program.
Good luck and peace to all!
