Re: my vertyanov jig wont work, Lenovo NM-273
Hello KTM.
Check all connections and also check for power supply for kbc +3valw. Sometimes you just need to press the power buton once prior preograming to get it to work. I know it sounds nonsence but try it.
Option 2 is to remove PR337 and connect the PU904 jumper contacts to get that 3v....

Re: 5/3.3v output issue
Thanks for your replies.Well I managed to fix it,sort of
That enable voltages were indeed to low,but i was thinking that pwm would not work below threshold voltage.
Culprit was in active short on PURE_HW_SHUTDOWN# rail,which affects "enable" voltage generation over D4001 diode,so it was hard to figure it out. Since that line is connected to Q2602 and Q2605 (Thermal shutdown protection) which are not populated on this board (UMA),I have found that this line goes straight to KBC at pin 85 "CMP_VOUT0",which has...Last edited by Djosla; 04-12-2021, 10:35 AM.

inspirion 15, Vegas/Turis SKL/KBL 15341-1 5/3.3v output issue
Hello,
Looks like this one`s gonna beat me
Motherboard: Dell inspirion 15,
Vegas/Turis SKL/KBL 15341-1
91N85
Loptop came dead,there was some liquid damage,near cd rom,nothing major,but after fixing that,main power supply voltages are not rising properly.
Instead of 3.3v and 5v i am getting 2,5v and 3,6v.
I have checked and changed every component around and including pu4503 (tps51225),but problem persists.
I have checked feedback resistors,output capacitors,mosfets for leakage,LDO outputs no shorts,i have...

Re: Dell SE2416H -need help identifying a component
Exactly but those smd markings are very hard to read correctly...I took a risk and turned on monitor without diode...It worked ok but hdmi input was not detected...So i took measurments and i have concluded that missing diode was powering a U110 eeprom from U703 and 5v from hdmi connector (pins labeled B and E of D110,pin C goes straigt to 8 pin vcc of U110)...So i put BAT54C diode in place...I had to replace the U110 eeprom because it was also fried. 24c02 replaced with 24c04 and freshly programmed and voila...Works as it should......

Re: Lenovo G770 won't work on battery
Ok no smbus enabled charging...good thing..
check this and post results (page 47):
1. resistance between pins 21 and 22 of PU301
2. resistance between pl301 and ground.
---than in active mode(put charger):
3. voltage on all pins of pq303 and pq306 and pq310
also did you check with good known battery ?Last edited by Djosla; 05-31-2017, 02:26 PM.
