Philips Laptop [15NB57] not powering up

Re: Philips 15NB57

 

Hi

 

Anyone any experience of a laptop proving very reluctant to switch on? The unit has not been mistreated in anyway [used by a teacher at home].

 

I have checked PSU - OK

Battery - OK and charging light switched on

Power button - OK [checked with multimeter]

 

It will switch on but could be after two hours of the PSU plugged in!

 

I have tried it without the battery installed and just running off the PSU but no joy.

 

I am guessing it might be a Thermistor cutting out???

 

Many thanks for any responses
