On some models, it is not unusual to see a CMOS checksum error when you first reboot the computer after installing the new BIOS. If you see this message on your screen, press F1 as instructed. This displays the "TSETUP" screen. Press <End> to save the CMOS data. You won't see the CMOS checksum error again.
If step 1 still not working for you. After you flash the BIOS, turn off the power to the computer. Holding down the tilde (~) key on your keyboard and turn on the power. This will boot up to drive A. [This still is mystery to me, I do not have drive A.] Than do step 1.

How old is the computer? seems like the memory battery inside the computer is dead, its 3volt flat battery in most cases.

Take the laptop to a local professional, they will look into the problem and most likely replace the battery for you.

Dell e5420 wont start up at all


Make sure no accessories are plugged into your laptop. First remove the battery and try a bootup. If does not bootup, remove the hard drive if you can and try again. If still no full boot, you can try the DVD drive and then the memory. Replace what you have found to be the problem. If none solves the bootup problem, it is either the power supply itself or a mainboard problem, which would required service from an authorized service center from Dell. Verify the center with Dell. The parts I have indicated to try are normally easily removed from the bottom of the laptop, by removing a few small screws.

this sounds like a bad flash, when you went to update the laptop did you happen to download any bios firmware updates? if so it;s a bad flash and will need to be reflashed to fix it.

Hp nc6000 wont bootup


hi thanks for using fixya!

On this kind of error, the only option you could do is to format your system, but if you are not so familiar in formatting your laptop, I suggest that you bring laptop to service tech, to easily perform error checking and reformatting. This error might be virus or software problems.

Thanks! hope this will enlighten you. please rate me! good luck!
