As i mentioned above laptop was dead because of shorted mosfet on battery input voltage after replacing mosfet device turned one but it shows 4 Amber one white , and it was not going in bios stuck on dell logo and same goes to F12 ONE time boot menu too ,
so i thought it has problem with bios too I Read one 8 MB BIOS chip with RT809h tool but it was not reading main 16mb bios it gives with verification error ,
So by mistake FLASHED BIOS WITH a dump from this thread, RT809h Erased the bios but on writing the error was the same so I took off bios chip from motherboard and this time it read successfully but unfortunately it does not have the data because it was erased when i tried to write when bios was on motherboard ,
So I have the data from 8MB chip i dont have orignal data from 16 MB
I TRIED FEW BIOS FOR 16MB CHIP BUT WITH THOSE FAN SPIN AND KEYBOARD LID OPEN FOR SECOND THEN GOES IN LOOP AS SHOWN IN VIDEO .
HERE IS MY SERVICE TAG : 7TD6303
