0251: System CMOS checksum bad-Whats this? ToshibaA105-S4254

\015 Dear All,I have a 2 yr old Toshiba A105-S4254.No software\015\012problems so far (except for the power chord problem, now solved, which is pasted below). But,today For the fist time when I turn the\015\012power switch on I get a black screen and I get this message (among\015\012other things that are written):"WARNING:0251: System CMOS checksum bad- Default configuration usedPress to load default to set up"I have no idea what this is. Which of the two F1 or F2 should I press?Thanks in advance, SangeetaPS: I have pasted the old probem which got solved last week below just in case it is related to this current one. Thanks PREVIOUS PROBLEM that got magically solved on its own is given below:Dear All,Ironically,\015\0125 days after the paid warrenty expired (2 years and 5 days after I\015\012bought this piece of equipment), the A105-4254, it suddenly died on me!It\015\012always had a "loose connection" to the AC adaptor. While working at\015\012home, I always had to pull and yank the power cable everytime I used it\015\012to make sure the "blue power light is on" and that power is being\015\012supplied to my laptop or else it would indicate that it is being\015\012powered through the battery instead.I lived with it. However around\015\012Christmas, when it was the season to be Jolly, the power cable\015\012connection started acting up big time and I perpetually had to hold the\015\012powersupply cable connection to the laptop with my left hand and type\015\012using only one hand. This went on for a few days. And then, on January\015\01217 2009, my laptop just died on me. Like dead dead.I bought a new\015\012powercord ($150)- nothing. I removed the battery and plugged in the AC\015\012adapter-nothing. No lights, no sounds, nothing. I cannot live without\015\012my laptop. Help.Please give some suggestion which do not\015\012include paying an arm and a leg to get it repaired (it is outside the\015\012warrenty remember).Thanks to all in advance,Sangeeta\015

Answers :

You can go ahead and press F1. If it happens again the next time you boot up or it just goes back to that screen try pressing F2 and then exit with saving.
\015\012This should solve your problems, If it doesnt you have something configured incorrectly in the CMOS.
\015\012If this is the case there should be somewhere that you can restore the defaults of the CMOS (as every computer is different I can't guide you through this process)
\015\012Have a great day.
