    Is it the Northbridge?

    I have a Toshiba L500D LA-4971P that was dead except for the power and charge lights. After a bios re-program and a northbridge reflow it will now post. However, it gives a "System Configuration Data Read error" and then wants you to press F1/F2 etc. Changes to BIOS make no difference and the error stays. It won't boot a HDD and gives a "no operating system error". Funny thing is a windows CD sees the drive but the install fails. Several HDD's have been tried. It also won't post if the top Ram slot is occupied.

    Would you say this is a northbridge error, particularly as the reflow managed to get it this far and the dead ram slot is a northbridge symptom too, isn't it?.

      yes , there is problem on south bridge , northbridge as nothing to do with the config data error , this is from IO reading , so give a light reflow on SB , if erro stop , reball or replace

      very common on L500 with grafic module

        so for upper ram slot (version dd3 or ddr2 ) , if ddr3 , replace cpu , if ddr2 , probably bad contact on bad northbridge ,
