As soon as anything appears on screen after power-on, press F1 (keep clicking it until the BIOS setup screen appears). The first option on the list is Date + Time, click on that, and enter correct date/time. Then press F10 to accept + reboot. If this error happens again, it means that the CMOS battery (which keeps your settings alive) has died; it is cheap + easy to replace, however you have an R40 model, and I avoid working on Rxx series so that job may be harder. I could point you to the R40 service manual, which is very good to dis-assemble that laptop (it is necessary to lift keyboard to get to CMOS battery, which involves removing some screws from the bottom.
What on bios is just what you answer yes or no but probably if there is any terminology been used that only where you might be confused but on bios is not compulsory for you to pass through bios you can leave the system and never press the Functional key been ask to press to move to bios settings and if you are tarckle the dates and time then move your arrow keys to the advanced settings from there click on the date is already shown like this 00:00:00 or better still with some kind of old date then on each of the 00: click on your keyboard the - (minus) and + (plus) on the keyboard to adjust the date to the current one ok and then press F10 to save and exit.
remove the battery and adapter. press power button for 30 sec. then connect the adapter. press power button. if this didnt work. you need to ask for an help of a local tech to check for the video card and cable.
You will have to take the palm rest off of the case. The battery, if I recall correctly, is attached to the under side of the palm rest. You MAY be able to get at it if you remove the main battery and look up into the case through the battery compartment.
I think you have an inverter board thats just about dead. It's located in the screens plastic housing at the bottom of the screen just above the keyboard. It's about 4 inches long and a half inch wide.There's just one little cable connecting it. But you have to take your screen apart to get to it. It's easy to replace and relatively inexpensive but it does require a little disassembly skill.
Also ,I will need the exact part number from the bottom of your laptop. There are several different R 40 models, and 2 different screen sizes.
Go to the IBM/Lenovo WEB site - support/download page and download the latest Windows XP or Vista device drivers for your model laptop,
You need to use a computer that has Internet access to download and transfer the files to your computer.
