hello everyone,

Got this Quanta U93 board for 15" with AMD A4-5000 and discrete graphics, converted to a 14" laptop by

Modify Battery connector: remove CN8 & install CN9
Modify ODD SATA connector: install CN20 & move c5700/c5701/c5702/c5704 to c5705/c5706/c5707/c5708

Board_ID 15" DIS to 14" DIS: move r2109 to r2108 (what is it for ?)

the board started, everything is ok but discrete graphics has (code 43!), tried to convert to UMA by moving r2107 to r2103 & remove PL9

the board started, but when the OS loads it begin to stutter (freeze/unfreeze continuously), discrete graphics isn't listed in the device manager

installing PL9 (convert only by r2108), same thing
removing D2003 (VGA_REQ) didn't help

where to dig ? bios ?

P.S touchscreen doesn't work although the driver is ok and listed in the device manager, both TS_ON_R & +VCC_TS are 3.33v

found it,

uninstall all graphics drivers then install uma driver from hp website... solved
