Dead 5150
Hi.. I could use some good advice. Dell replaced the motherboard on my laptop when it was 6 months old. When I received it back... it still didn't work. They then sent me another AC Adapter and the computer worked fine... for 6 months. Tech Support felt that it was the motherboard and they sent me a new motherboard. I replaced it and it's still dead. They then sent me another thinking that the replacement was defective and I still have the same problem... computer is dead!
I think it may be the AC adapter again but the LED on the brick is lit and it measures 14 volts.
When I try to power on the laptop with the battery in, the battery LED flashes twice after pressing the power button. When the battery is removed, both the power and battery LED blink on once every 7 seconds.
I picked up a generic AC adapter at Computer City that has about 10 different plugs but it doesn't mate with this computer.
Thanks for your help!

Hi I apologize, for the static comment, but more, people have no idea about anti-static pads, or wrist straps...Oh, it just might be the power adapter after all, it should be pushing out 18Volts not 14 !mine does anyway!GW5150gimpwith5150

Yep, sounds like it...
Since you've already had a few problems in this area too.
have you ever had the voltage in your house checked?
I had to have the electricians put a regulator in my house.
after I moved in, & kept blowing bulbs all over the house, after 2-3 weeks..I called them up.
Upon inspection they told me my voltage was swinging from 112-126, causing the filaments in the bulbs to get hotter & colder, way faster, thus buring out..
Maybe something similar to this is causing, your Adapters to fail?

Try holding the
i button next to the power button.
I read that holding in this button in for 10 seconds, will clear the CMOS on a 5150,
maybe that is all it needs..Your Power Adapter seems fine at 14 volts...
A Dell support, guy came out, to replace the cooling unit, & motherboard on my Dell(it was running hot) He had to flash the BIOS, before the notebook even wanted to work.
If you have a USB floppy & can boot from it, try flashing your BIOS,
if after holding in the, i button does work, in clearing the CMOS..
It sounds like you might have Statically charged the CPU, during the time you replaced the mobo..
