My computer is just shutting down with no warning. I took off sides to make sure all 3 fans are working and they are. I am thinking that the power supply might be bad. The unit is not getting hot. Any ideas.
Michael
at first chack at which time it shutting down. if it happen when u click on any drive or when u using cd/dvd drive then power supply cant regulate power. then chack switching transistor and filter section capacitor.
(Be careful about filter capacitor in primary section because some time it stored high voltage dc after plug of power supply at first discharge this two capacitor.)
** also chack supply voltage r stady or not.
2) the Battery should be good, the charging issue is also link to BIOS version support, or check dc jack LED indicator on when adapter plug in. not lights no charging
3) check adapter plug in DC jack lights, shutdown could be related to if the lights not on. may be try change adapter first
