Hi Im looking for schematic or boardview file for this model : Toshiba L770-14C 69n0y3m1gb01-01 BS_R/TK_R rev:2.1 P/N:08N1-0NA1Q00 If anyone can help that would be great.

Hi is there a da0blimb6f0 rev: f schematic available please?. Many thanks

kotnatan:Do you have schematic that matches this?

kotnatan: Many thanks again. I will check if it helps later.

kotnatan: Please upload as this may help. Many thanks

Hi would anybody have boardview and schematic for Asus f50z 60-nt9mb1300-a02 rev:2.1. I already have the F5Z schematic but its not the correct one. Many thanks.

I put the coil back in place and now I have the 3.3v and 5v I presume its due to the feedback loop I re soldered PL13 and then then bench supply returned to switching on current limit and going back into the loop. I then removed pq45 and pq44 and the 3.3v returned to pl13. but if I now put 3.3v into either of the +3v (pq45 pin1) or +3v_s5(pq44 pin 4) the the overcurrent kicks in. So basically Im looking for a fault common to both lines. Any help appreciated

Hi I have issue with 3.3v on Sony motherboad MBX247. I have replace the regulator pu9 (pm6686) and the KBC (slight liquid damage) and lifted the coil PL13 on the 3.3v line as theres also a short farther down on the +3vpcu line . But for the moment I am trying to get 3.3v from pu9 (PM6686) but not getting output. Thisis what I measured so far on the regulator. Pin1 ref 1.8v Pin2 Ton 0v pin3 vin 4.9v pin4 enldo 4.9v pin6 vin 19v pin7 ldo 4.9v pin27 en1 4.9v Any ideas why Im not getting 3.3v out?. When I connect Coil pl13 the bench supply just jumps to 5v then current limit kicks in and it goes to 0v and just keeps cycle. But with the coil lifted on one side the 19v vin stays but no 3.3v output.

Hi anybody know if Schematic is available for Fujitsu Ah532 FH6. Many thanks

I reflashed bios with the second file in the bios package and now current usage goes to almost 1A but the screen stays white with no external output either. Maybe the screen cable is faulty also. I still need the proper schematic aswell.

u13 is some kind of regulator but I cannot see the markings on it. If I had the schematic I can do more testing.

Hi unit was dead initially had 3.3v an 19v in so flashed new chip and replaced faulty bios chip (as it would not read in my programmer). Now get unit powered on but only 1/2 A current drawn and no video. I have 3.3v/5v/1.5/1.05. I have the Tahiti and the Arwen_a1 schematics but both are not correct for this model. U13 looks scorched. The motherboard markings are HPMH-40GAB4200-D430 AND ALSO ON MOBO PCB:41-AB4300-D00G. PWA:40GAB4300-D. Any help is appreciated.

Thats the model number of the motherboard its used in lots of Sony Models, the name of the schematic is also MXB-223 M971. I have the schematics but the boardview file is hard to find.

Hi does anybody have a boardview file for this model MXB-223 board?. Many thanks

That is because its not resolved as Im am waiting on replacement Ic. When an issues is resolved I will mark it so. I cannot seem to find the resolved post. Basically when the laptop is powered up it only draws about 1/4 of an Amp then shuts down immediately. As it shuts down so fast I can only measure the 3.3v which is present all other voltages either do not appear or appear only briefly.The unit then powers off and on in the same loop over and over by itself.
