HI mark it did it this morning just the power light came on and would not boot up turned it off and left it for a while tried it again and was fine then did the same again this evening but now just power light is on no hard drive lights
When your doing these tests.
1. Remove the Battery.
2. When you power off remove the power lead from the laptop. For about 30 seconds.
That will help with diagnosis as it keeps the environment at a good Base to work from.
It is possible that the hard drive lights are not doing anything as there is a screen problem and you cannot read it. Windows will do a count down of about 30 seconds before it goes with what it wants to do.
You should normally see the screen light up with a logo or Boot sequence.
Give this a go it happens on my good old trusty laptop.
Simply close the lid and open it again. Try this a few times. And try to follow the screen with your eyes as you open and close the screen, as it may just be a trapped cable pulling or loose.
Let us know how you get on.
