Datasheet «AO4407»

The bit about the solder bridge across the two center pins on one side of the AO at http: The same thing happens when two heated solder joints ‘bridge’ and connect to each other. Release the power button.

I cannot repair laptops for you via the internet, I can only answer questions related to posts. 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. Posted by Hoosier Newman at 5: Word I have heard is that if the CR replacement isn’t the problem, try 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.

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: HP DV3 series has the same design as well. AO stands for Alpha and Omega Semiconductors part. Now hold the power button down and connect the AC adapter. I can’t find schematics anywhere Your thought processing is wonderful.

Mayo Hardware Sat Apr 23, Unknown July 14, at 1: Only a member of this blog may post a comment. Unplug power supply from wall to reset. It shuts down because of ao440. It’s not a complete short National Semiconductor, Fairchild and others. 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. Upon doing this I assembled the laptop and it came on the very first time and worked great for the customer ever since.

Flux helps bridge that space between them and makes the contact happen. Unknown July 14, at 2: Dxtasheet its pretty easy.

I insist that flux is used. Compaq Presario C C Common problems and how When ordering replacement motherboard you should play close attention to the part number. You are really a master.

I have a dv7 with the exact power issue you described in a different post but not the same mosfet. If you do need it repaired. Reading mosfets in circuit can be tricky.

Thanks for the help. If it does charge the battery, the charge will not have sufficient current to the LiION particles. Hello just curious if an ao can be a suitable replacement for an ao I had no power or lights replaced the pq and now the charger light blinks and still no power supply light or power up.

Romar Sat Jul 27, Unplug AC adapter and remove battery for minutes. Just trying to help others see things a little clearer.

Make sure fatasheet CPU is removed or many n-channel fets will read shorted. Nothing against Indians, but their support went to shit when they offshored it there. That was amazing http: Once this is installed you will want to go to www. The short and long versions of the hard drive self-test have been combined as one test option.

This is a common problem for many laptops.

That’s about the size of HP support. Before trashing the computer or ordering expensive parts go out and buy a CMOS battery and see if that does the trick. Looks like part wo4407 With some training, it’s not that complex to repair most problems.

Could this be the problem? So you get a complete catalog of various FETS at different ratings in amperage, voltage, and configurations.
