Great pic with mosfet function http: How to repair Laptop. I ask because sometimes I’ve read 19v at drain while only 5v is at the gate but yet on others, the drain voltage is equal to whats being applied to the gate.

Hi Lindasy and thanks for the kind words. I just may be overly cautious. Now hold the power button down and connect the AC adapter. Could this be the problem?

Posted by Hoosier Newman at 5: The FET should only read dtaasheet way in diode mode, since it basically a diode that is turned off or on. AO stands for Alpha and Omega Semiconductors part.

Thanks your bolg is very helpful. The same thing happens when two heated solder joints ‘bridge’ and connect to each other. Your thought processing is wonderful.

Datasheet «AO4407»

That was amazing http: DV has heatsink for video memor management unit MMU cause it has onboard memory. I guess in a mental image it is similar to the way magnets attract to each other al4407 too close. That’s about the datazheet of HP support.

Thanks for the response, I Will get an ao out of another board if I can find one and post my results. The arrows shows the direction for reference when using a meter to test. I cannot repair laptops for you via the internet, I can only answer questions related to posts. Could you contact me directly. This blog datxsheet created to compliment my blog on Laptop Reviews New and Used laptop reviews by helping you the laptop owner repair your own laptop.

With the number of balls under the chip, it is difficult to get it enough heat evenly before scorching the topside of the GPU essentially datssheet it. HP DV3 series has the same design as well. Nothing against Indians, but their support dataxheet to shit when they offshored it there. The GATE voltage may be different based up on the part specs. Unplug AC adapter and remove battery for minutes. Andy Wed Mar 09, The way you tell the thing is awesome.


I was frustrated with it myself until I done a little trial and error until it was fixed. If the power is too low, it will not charge. Anonymous February 19, at 3: Thanks Life for the kind words. The bit about the solder bridge across the two center pins on one side of the Dataeheet at http: One guy had a solder bridge, and fixed it by simply clearing that.

The diode test on pu fails It drives me crazy probing these things sometimes. As long as your hard drive is not throwing the error because of a hardware issue this should solve the problem. The lights should come on for about 5 sec. Mayo Hardware Tue Mar 22,
