hello all

since buying a nice 42" hd tv i would like to feed through my dock to tv using dvi to hdmi , i can get a cable ok but my problem is the vid card in the dock is drawing to much juice, i reckon, so i need to find some sort of voltage monitoring program to check that is in fact the issue, if so then i will rig a better power supply , well thats the theory anyhow, ihad noticed during intensive game play i would get a slight screen blank , the card in the dock is an fx5500 256mb pci , unable to find power needs for it.

Info I can find is that a 256Mb PCI FX 550 requires a minimum 250W system power supply - can't find voltage info

no graphics card requires 250 watts. they write that because a 250 w power supply will ensure that the separate voltage channels have sufficient ampères.

look at the pci specs to know what the max. power will be.

however, it might well be that the power supply inside the dock is not strong enought for the graphics card. you could try removing the battery from the thinkpad and see if that changes anything.

thanks

have tried with no battery plus fully charged my feeling is that the dock gives about 120 to 150w the t30 can run from a mains supply adapter of around 75w (90w ideal) so the vid card must be drawing at least 100w , i tried speedfan utility but does not seem to support whatever chip is onboard t30, if i can log voltage then i can see if forcing the vid card to work hard, is the problem and not chipset or som other unrelated problem,
