I HAVE a Studio 15-i5 windows 7 laptop. Whenever i start my laptop after the dell logo comes erro window(black in color) comes and show “CMOS CHECKSUM ERROR” and when i RESUME or even change date or time ..i get some problems such as gmail,gtalk,etc doesnot open.
I m worried about how to tackle this and also Can I keep using the laptop by ignoring this problem as will the failed bios battery affects my other laptop parts in future…

open CMOS battery from CMOS slot and do ESD(electro static discharge)and placed that CMOS battery in slot and switched on your system.

Hello, I have a HP DV3000 laptap with a CMOS battery CR2016. I tried to find one but got a CMOS battery for DV2000. Will it be okay if I will use the CMOS battery for DV2000 as a replacement for my CR2016? It has the same voltage 3v. Not sure if this will cause any issue on my laptap or distroy my motherboard in the long run. Need your idea on this case.thanks!

i have my desktop pc with intel D945 motherboard having 1 gb ram, worked very well for last 4 years but last time when i switched it off and restarted it is not getting started and the monitor screen shows intel and press F2 for bios settings but nothing happens when F2 is pressed. When i removed d RAM THREE bEEPS were heard. i changed d ram but of no avail. I also checked its hard drive which is spinning n seems normal. All connections to motherboard are also o.k. Is this the cmos problem or any software problem………..
Plzzzzz guide………..

Nothing to do with the battery. It is probably the video chip.
When they say video card they mean video chip in the laptop.
The chip should get resoldered or better replaced.

Hi, I have a Dell Dimension C521, almost 5 years old running Windows Home basic. I cannot get my puter to boot up, will not POST, nothing but the fan blows and light goes solid amber color and the dreaded black screen. I’ve heard it could be video card failure but I don’t even see a card hooked up, strange cause obviously it has to have one somewhere, but aside from that as a possible, could such a little thing as that battery (which I do see LOL) really render the whole computer useless like this?

Thanks…Candy
