some of the voltages I measured: DC jack = 19.93V +VA = 19.90V +VAD = 19.71V +VIN = 19.71 V +5VPCU = 5.25V +3VPCU = 3.45V +5VALW = 5.25V +12VALW = 8.70V ?? is it fine or is it overloaded somewhere? some one told me it can be low intially and then once laptop starts it will reach a normal value. seems unlikely though.
019 NBSWON#1 =3.4 / 0V (before /after power button) 090 DNBSWON#1 3.4 / falls to 0.2V gradually rises to 0.5V and settles there
95 RSMRST# 0V / 2.8 V only for half a second when you press the power button and then falls back to 0V
16 SUSC# 30 mV / 275mV again falls to 30 mV06 SUSB# 30 mV / 550 mV again falls to 30 mV
BIOS ( U22 sheet no 34) Pin no. name voltage 1 BIOS CS# 0.18 V isnt it too low? 2 BIOS RD# 1.64 V 3 SPI 3P 3.4 V 4 VSS 0 V 5 BIOS WR# 0.25 V 6 SPI CLK 1.5 V 7 SPI 7P 3.4 V 8 VDD 3.4 V
I would request you to kindly let me know what is going wrong which is preventing the rsmrst voltage from getting high. it tries to go high but falls down immediately to zero. also the bios pin 1 is not getting enough voltage. what is wrong there?
I don’t know what to do now. Kindly show me the path to tread.
Thanks in advance

im no electonic but it would be easier to replace the motherboard
that will be the last resort........ trying to find a more TECHNICAL answer.
