[gayan123]

Sir this laptop not coming voltage for MOSFET gate to power on. Please tell me which voltage need to on this ic.
We short mosfet and on my laptop but I need to know which voltage need to drive this ic

@ first : vcc
2. acdet
3. communicate with io with adp_i line

if motherboard have any problem , I/o prevent ic to drive input voltage . did you ohm check b+ voltage line ??

Sir how many voltage need to receive adp-I line. I_line voltage 0v pin no- 7

 

[gayan123]

mosfet volt also not coming / b+ not any short.

mosfet volt also not coming / b+ not any short.

acp and acn have 19v ??? but have not b+ ?

 

[gayan123]

acp and acn have 19v ??? but have not b+ ?

Yes second mosfet short and can power on laptop and work properly

 

[Hosein Asadolahi]

Yes second mosfet short and can power on laptop and work properly

did you replace ic with new one ??

 

[gayan123]

did you replace ic with new one ??

Yes first you ic not present ac ok also. After replace ic that Time present 3.3v ac ok. But second mosfet voltage .888mv

you say "But second mosfet voltage" , are you mins pq701 ??
this model have one input mosfet .
did you check with another adaptor ??
did you check psid signal ??

Yes bq701 . Check with another adapter but same situation. Sir please tell me how to check “psid” signals.

Yes bq701 . Check with another adapter but same situation. Sir please tell me how to check “psid” signals.

check all pins of this mosfet and share it . pq6
