Re: HP LA-E801P power off after few sec
Thanks all., I physically removed TPS51225C (which was also getting hot) Injected 3 volts on VREG3, & KBC KB9022Q gets hot.. Similar problem was with the other board too. I replaced the KB9022Q but still the new chip was getting hot. I think the problem lies somewhere else. The only difference was when I removed KB9022Q I checked the resistance on the Caps & it was normal NOT 2 ohms, but when I soldered KB9022Q back again the caps again showed 2 ohms resistance. Something within this circuit is faulty which cannot figure. Hope I get a Schematic to check when about this circuit leads too.
