I have got my brand new Lenovo Thinkpad T450 laptop a few monthes ago. Firstly I would say that is does not meet my expectations but there was still no problem till a day ago. I used the laptop till the battery completely dead which is resulted in shutting down suddenly. Then I plugped AC and tried to turn on back but it do not turns on still. Also the lights on Fn, F1 and F4 buttons are on. So, I click on power button but it does not turn on. I searched some info on internet and found that it may be possible to turn when to click 10 times on power then click and wait 30 seconds, but there is no result. The laptop does not turn on. What can be the problem? What I can do?
I have tried it several times but it doen not work.
My laptop is Thinkpad t450. You know that in t450 thera two batteries. One is internal and one is extarnal. I have tested the method you suggest by removing only extarnal battery. So, may it be because of this issue? So, If can remove both batteries can it be work?
