LENOVO T450S FAILED TO POWER ON

2016-07-02, 14:43 PM

Hello guys. 

My ThinkPad 450S was all working fine until I switched it off last night before going to sleep. On wake-up I tried to switch it on and find it not responding. I tried to plug the power adapter only to find it not responding too (normally on plugging the power adapter, the red light on lid's ThinkPad flashes and the green light on the power buttom also flashes). This morning they were all dormant when I plug in the power adapter. Before I switched it off, the batteries were full (100%) as it has two batteries internal and external one. I didn't try to open it or do anything about it, may be this evening. 

What might be the problem and possible solution to it? 

Please help me out. 

 

Regards, 

Cathbert.

Push a straightened paper clip lightly into the emergency reset hole on the base cover.  (under the touchpad near the lower middle)

Thank you @Richk , your solution worked out perfectly. I didn't even notice that emergency reset hole before, so I learned big time.
Be blessed.

I keep having to push on the emergecy reset button after having it off for a day to power it on.

I have replaced the CMOS battery. Should I replace the internal battery or the motherboard? Or could it be the CMOS battery I replaced is bad?
