we bought 6 units of HP Pavilion BF061tx notebook.. out of 6 units 3 units got sudden shut down and can not power up ( no light in power indicator)
...what is the cause of this ?
1st we check the power adapter but it was good . then we try to plug and unplug the power connector for several time some revivied . and in one unit we did the disconnect and connect the battery and it was immediatly revived .
we though the problem is over . but after one week more . problem occurs again ..same defect .
It was alraming we can not just use disconnect and connect method .
we need why and what to do about it
