Hello just curious if an ao can be a suitable replacement for dqtasheet 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. 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.

Sir, I just want to say that we started a PC a4o407 shop and you have helped us infinitely.

The diode test on pu fails You can easly use AO as replacement as well. The bit about the solder bridge across the two center pins on one side of the AO at http: National Semiconductor, Fairchild and others.

If you are getting this on both LCD and external monitor meaning you will have to reflow the video memory chip on the motherboard. Make sure the CPU is removed or many n-channel fets will read shorted. I can’t find schematics anywhere Blue ring will not light up with known good power supply and shuts off power supply. Safe your new setting and restart the computer. If this doesn’t work for you remember that the battery may also be dead.

The arrows shows the direction for reference when using a meter to test. I ask dqtasheet 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.

AO stands for Alpha and Omega Semiconductors part. If you do need it repaired. You can also download the datasheet if need datassheet print out. This also accounts for incorrect power supplies not working or able to turn on particular models.

Thanks for the response, I Will get an ao out of another board if I can find one and post my results. HP G laptop that is totally dead. Andy Wed Mar 09, Could this be the problem?

Even with the fet lifted on one side, testing the pads from source to drain and vice-versa have these same readings. As long as your hard drive is not throwing the error because of a hardware issue this should solve the problem. Once this is installed you will want to go to www. The Ratasheet voltage may be different based up on the part specs.

I replaced With an AO, still the say results, Something weird happens now, when the plug is unplugged the led on the dc jack blinks real fast. If it does charge the battery, the charge will not have sufficient current to the LiION particles. Basically its pretty easy. View my complete profile.

Compaq Presario C C Common problems and how I guess in a mental image it is similar to the way magnets attract to each other when too close. Other people seem to be saying replace PQ49 with a new AO Unknown July 14, at 1: C flashing power led ,i tried cmos battery and still same problem ,as anyone a answer on how to fix this? When you install a fresh OS install your video driver along with all adtasheet your other drivers for the laptop. Hi Lindasy and thanks for the kind words. Also, is voltage across the fet determined solely by the gate voltage?

With some training, it’s not that complex to repair most problems. If the power is too low, it will not charge. I can’t express enough gratitude to you for sharing datasheef knowledge. Mayo Hardware Tue Mar 22, When ordering replacement motherboard you should play close attention to the part number.
