I have a old school IBM Thinkpad a laptop. Want to get working so my kids can use it. Son dropped it awhile ago and now it will not turn on. I know it could probably be a few things that is wrong with it, however hoping by the description I provide someone could narrow it down for me. The laptop is getting power, the charging light indicator comes on when plugged in. When you push the power button all the lights flash once and you can hear the fan click like it wants to start but doesn't. Any ideas?
