Re: 4455 mofset alternative?
pu301
Vcc dead 0
Maybe causing 19v 0.0amps not drawing amps
Can that be the cause...Last edited by Stevie2001; 07-06-2018, 12:34 PM.

How to find short: just want to share
Connect gnd to ground.
Test probe on + if it beeps then solder a wire and connect
Dc power supply and inject 1v 050amps and increase.
Some shorts maybe with other parts on board but you can use this same method.
Use lighter petrol or freeze spray thermal camera works best
For power faults only
If the board is taking in voltage and no amps then use method above.
Sometimes if you are on 19v and 0.0 amps increase a little bit till you se 1amp and fan will kick in on dc power supply.
Share your methods...Last edited by Stevie2001; 07-04-2018, 01:44 PM.

Re: DAX1BDMB6F0 Power Issue
Do this if you do you will save shit load time.
Since it is power issue spend time taking notes down like this.
Your motherboard has power or charging ic find the main power if its hard then go through it one by one checking the number on ic and google it.
Your looking for power controller ic google it by looking at the numbers on top of ic and check the datasheet for each ic and the pins and here is what you do.
Looking for short.
Check datasheet which pin on ic is gnd and then ignore that pin and set...Last edited by Stevie2001; 07-03-2018, 08:29 AM.

Re: How to make good flux paste
I have tried that it works but its not creamy or like vasoline.
But i tested it and it works very good it bubbles around the component as heat gun is applied this just helps any parts boil faster.Last edited by Stevie2001; 06-29-2018, 03:25 PM.

Re: Lenovo Yoga 910 Charging Problem
If your seriouse about handling customer repaires without minimum online help effort i suggest you invest in getting flir thermal camera.
With these you can fix shorts and other problems instantly.
Your working hours will be cut and you can get it repaired fast. You will find and locate problematic components soon as you even plug the standard charger.
Bite the bullet get one....
