Hi guys n girls,
I wonder if someone can tell me if this part is suitable.
This is all I can find 3271V SLG3NB3271VTR QFN16
I have a 3271V 2N002MX1 on my board so can the above be used??
Many thanks.....

Hello many thanks for putting up with me
I will do that and report back my findings thank you.

Re: Toshiba Satalite P850 power goes off after 3secs
Hello again and hope all is well.
So far Q30 has on the drain pins 5.1v and 3.7v on the source pins with no change if PWRBTN is pressed.
Q29 has 3.4v on the drain pins and 0v on the source pins with no change when the PWRBTN is pressed.
Going to look at the SIO pins 106 115 101 100 6 14 116 114 now.....Leave a comment:

Re: Toshiba Satalite P850 power goes off after 3secs
I have purchased a new muiltimeter as mine was very old and the display was going and a hot air station to remove faulty componants.
Do I need them for this board or have I wasted my money?...Leave a comment:

Many thanks techtiger
I managed to find the UCL1 with the part No. 3271V 2N002MX1
I will look at the others..
SIO = Serial Input/Output
LDO = low-dropout regulator I'm learning...

Hello again,
Check the RTCVCC line Remove RTC Bat & RAM with no power to MB hold down the PWRBTW for 10 Sec put back everything & check, I did this and there was no change..
TPS51125 LDO, I don't know what that is and if I'm testing PL332 + PL352 correctly there is 3V/5V. The UCL1 IC I can't find that sorry but this well could beyond me..
The only TPS I'm familiar with are found in Cars

Looking at this for a family member.
It was working and after working away for some time and when returned home the LT then didn't start up - so I'm told. What it does is when the power button is pushed the light on the power button and LED on the front both light for say 3sec and goes off.
