Laptop Repair In Hyderabad

hello welcome to Adi double one triple acer laptop repair  T YouTube channel this one is dil 3 5 37 mm MIDI its part number is Ali 9 9 8 2 P region 3.0 okay in this amid a problem is when we connect adapter we connect adapter and try to switch on it's not getting on ok now acer laptop service  we check first we take 19 volt line is okay or not this is the connector and now we open somatic connector number is pjp DC continuity from which MOSFET it's connected red line this one's be l1 l1 connected  sony laptop service okay first line is connected with this pl-1 fuse then PQ 7 0 1 ok now first we check voltages 19 volt connected we cheek on connector first 19 volt okey then fields from also 19 volts then PQ 7 0 1 output size 19 volt ok everywhere 19 what is OK in this section now we check on input side of section 19 what we required we  Dell laptop service can see this also the L 1 0 2 only 0.77 ok now we open somatic and take from where B+ is generating it's PQ 7 0 1 this is the symmetric of this MBD this one is PQ 7 0 1 ok you can see PQ 7 0 1 as we know pin 1 having 19 volt and pin 3 having 19 volt lenovo laptop service  okay this one is charge b-plus line we see 7 2 4 is the last and PL 7:02 now we take voltages at PL 7-0 to first okay then okay first we check voltage on PL 7:02 when we connect adapter and PL 7 0 2 this one is PL 7 0 to 19 volt is okay as you can see 19 volt is okay here and this 19 volt is goes to MOSFET of battery  hp laptop service I see then b-plus signally generating from here there is PL 7 0 1 + PR 7 1 6 now with check voltages at PL 7 0 1 and PR 7 1 6 and MOSFET side this side also okay is okay or not PR 7 1 6 this one is PR 7 1 6 you can see point 77 other side point 77 and while PL 7 0 1 but require also point 77 means B plus signal is missing okay lenovo laptop service  B plus signal is missing and this B plus is going to everywhere means every section in this MBD ok now first we take its battery I see okay as you see the voltage is pr70 tuned and in voltage okay charging v+ is okay PQ 7:01 first we check this MOSFET working okay mm voltage on pin number one three two and four no  dell laptop service  we cheat on put side pin number one this one is pin number 119 volt okay and it's pin number 319 okay and pin number two is gate this one is gate gate side it's nineteen point seven three and pin number four 19.7 two all are same gates hp laptop service  you to be high first we check battery I see rocky I see pins okay spin number 119 volt you see in okay pin number two also nineteen volt okay pin number three eighteen volt in number four 20 volt it's 20 volt pin numbers five three point six eight in number six two point six two you can see pin number one is ACN if so can acer laptop service  and involed ACP it's also nineteen volt okay pin number 3 cm SRC it's about 20 volt okay and pin number for a CDR V it's about 20 volt means  toshiba laptop repair 19 volt is also pin number 6 is 3.2 means AC detector is okay to point something and Laptop service  pin number 5 is AC okay it's also 3 volt means AC okay AC in signal E also okay okay now first we check this ever dot on this MOSFET first we check this MOSFET about this MOSFET we search on Google about this MOSFET interrelated  laptop repairs little bit slow know as dell laptop repair  we can see I have put this MOSFET number eight seven three one two and Google okay and it's souls it's an channel and laptop repairing  channel dual MOSFET okay dwell N channel MOSFET 30 volt and channel MOSFET okay as we know it's an channel MOSFET okay it's an channel MOSFET means it requires high voltage at gate to operate but it's having nineteen volt first we replace this MOSFET and check what happened okay as  laptop keyboard repair we know in this Emma d-19 mold is present there okay but not going to other sections means B+ is missing in this MBD okay now replace this now I'm going to replace EQ 7:01 now I have replaced this MOSFET this was laptop repair the old MOSFET okay now I'm going to check what it is again input side mind inverter again output side n 19 volt now we take a gate of this MOSFET gate is twenty five point eight one no gate voltage is okay okay now we laptop repair services  take B plus signal as we asus laptop repair  can see V Plus is coming from PL 7:01 which connected with PL 7:01 and P are seven one six now we check this voltage is coming or not now laptop repairs  we take PL 7:01 13.5 150 okay both side thirteen point fifty forty is okay voltage okay everywhere 13 point acting now we take at every section here is starting point five one okay thirteen point five one no switch on  best laptop repair the month which now we best laptop repair  take display connect adapter until John on this blue okay thank you thank you [Music]
