Hi Dno101,

I recommend you to remove the battery and disconnect the adapter, press and hold the power button for few seconds and release to drain the flea power .Now put back the battery and connect the adapter and power on the computer and check.

You may also check by connecting a known good adapter.

For graphic card upgrade, Alienware 15X ships with Nvidia GeForce GTX 260M and Nvidia GeForce GT 240M.

Alienware M15x is now available with ATI Radeon HD 5850 / ATI Radeon HD 5730 Graphics card.

I am afraid Nvidia Quadro FX 3800M is not tested on this computer. You may try upgrading the Graphic card to Nvidia Quadro FX 3800M by taking the computer toa local store and try changing the graphic card.

 Please reply for further questions.

thanks for the quick reply Rajesh.  the only way i can get it to power on is to remove the battery and power drain as you suggest.  the time setting then defaults back to 2009 which was when i bought it.  i was wondering if anyone had a permanent fix for this problem.

so if i put 1600mhz in it, i presume it will just clock back to 1333mhz?  was hoping there might have been a bios fix.

will check out them GPUs

thanks again.

Dno

My M15 R1 uses 1600Mhz ram when I overclock it just fine.  You should update the bios to the latest before trying this.  In overclocked mode 1333mhz ram does not post.
