If you want it looked at, I can check it out if you bring it to Miles City. If it is a battery, you buy it, under 3.00 and I will install it free.
BTW if the computer is not booting, a battery is not going to fix your problem. If it was a bad cmos battery, your computer would boot to a screen with press F! on it, but it would give you an option to boot.
What a battery does is power a real time clock and cmos in order to keep settings. Newer computes auto detect settings when they boot up, so they now give you the option to continue or to enter setup or cmos, in which they are the same thing.
If you are getting the blue screen it may be a totally different problem. Either way I would diagnose the problem for free. If it is a battery issue I will put it in for free, if not I will tell you what is wrong with it and give you an estimate.
In case you don't know me I have more than 25 years experience.
