Shawn Hustle Russell Wed Feb 16, Mayo Hardware Wed Feb 16, The lights should come on for about 5 sec. Now hold the power button down and connect the AC adapter.

The GATE voltage may be different based up on the part specs. Imagine the flow direction Drain to Source. Other people seem to be saying replace Dtasheet with a new AO That was amazing http: Unknown July 14, at 2: If this doesn’t work for you remember that the battery may also be dead. Feel free to chime in. FETS also come in different current ratings, so a DV charger will not charge a DV because a 65w power supply will not charge a 90w unit.

Imagine the flow direction Source to Drain. Each mobil processor has a max temperature rating. Mayo Hardware Sat Apr 23, About Me Jesse In a world of uncertainty and aggravation I will try to help bring a smile to your face one random thing at a time: Great pic with mosfet function http: This is usually the case with U.


Word I have heard is that if the CR replacement isn’t the problem, dxtasheet the 8-pin chip labeled PQ49 on the power-button side of the motherboard, just to the right of the laptop battery blades, and directly next to a large resistor. Once this is installed you will want to go to www. Safe your new setting and restart the computer.

Dagasheet cannot repair laptops for you via the internet, I can only answer questions related to posts. Here are couple things that I found fixed the very common but almost unsolved problem with these laptops. I was frustrated with it myself until I done a little trial and error until it was fixed.

Check AO switching mosfets on power source side on mobo just where power entering. I has several purposes. These fixes are also for the C and other similar compaq and HP models. Once installed restart and your sound card should be recognized and working!

When you install a fresh OS install your video driver along with all of your other drivers for the laptop. I think there may have been other soldering issues involved. Just trying to help others see things a little clearer.

But it is not a hard and fast rule with some Chinese manufacturers, and may need to check the datasheet before assuming they will be the same. 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 damaging it.

The FET should only read one way in diode mode, since it basically a diode that is turned off or on. Learn How to Repair Laptop! Unplug power supply from wall to reset. Pressing the power button gives nothing, connecting the AC adapter gives nothing.

Thanks for the response, I Will get an ao out of another board if I can find one and post my results. Make sure the CPU is removed or many n-channel fets will read shorted. Thanks for the help. Posted by Jesse at Hopefully I can save you some of the headaches that I had. C flashing power led ,i tried cmos battery and still same problem ,as anyone a answer on how to fix this? I insist that flux is used.

AO4407 SO8

No lights or anything. They have considerably different values. Thanks Life for the kind words. Thnx for helping us all out.

Mayo Hardware Tue Mar 22, Even with the fet lifted on one side, testing the pads from source to drain and vice-versa have these same readings.
