My battery was completely dead so my Laptop was like a normal TV. When Light goes off, it goes off automatically. When there is Light and I turn it on, what I normally get is Checksum Error page telling me to press F1 to load COSMOS default value and when I do that, the system will load normally but my date and time will reset back to 2001 so I will have to reset it any time I put on my Laptop.

I decided to change the battery and everything was Good until 2 days later I started getting completely blank screen whenever I turn on the Laptop. The Power button and the WiFi button will come on but the screen will not power On. Just completely dark. So I'll have to leave it like that for about an hour, then hold the power button for it to shut down then when I on it again before it will be able to display normally.

When I on it sometimes for the first time, it will jus show the power light and off immediately and at times it will just be blinking.

I thought maybe the battery that I bought was bad but I got the same result when I decided to power it on without the battery.

So Experts in the house, if you understand what the problem is, please help. I'm thinking maybe it the BIOS battery but I want to be sure before changing it.

First thing I am guessing is that your CMOS battery is bad and needs replacement, also at the time the your PC was operating like a TV, due to improper shut down of the PC in a continuous manner, there is a high probability that your hard disk has gone bad, also that might need replacement...... Shut the TV off (PC), then turn the power button on, immediately it comes up, click on CNTL+ALT+DEL and follow the procedure from the blue page that comes up...... I hope this works temporarily for you

Cheers

I also replaced the hard Disk but the previous one was still functioning properly. Both the New one and the old one are having the same issues. I've tried it on both hard disk and it's the same result.

About the CMOS battery, I think I would work on that first.

And as for using ALT + XTRL and DEL, the system screeb does not power on when switched on for the first time. I'll have to leave it on like that for almost an hour then press the power button till it shuts down then when I power it on the second time, it will come once. Also if I should shut down and come back to on it in the next 3 hours, it will come on normally. But if I should wait longer for it to get cold, I will have to do the double power thing for it to come up again.
