Toshiba Portege R100 CMOS/BIOS PROBLEM at startup.
I am working on a Toshiba Portege R100 laptop. When I got it, the RTC battery Was stone dead. I replaced it with a new one. When I turn the machine on, The Toshiba screen flashes on for 1 or 2 seconds, then it goes to either one of two different screens. One screen says ( RTC battery is low or CMOS checksum is inconsistent !! ) Press F1 KEY to set DATE/TIME. If I hit F1, I go into the BIOS, but can do nothing at all in there. The other screen I get , once again, at startup, the Toshiba screen flashes on for 1 or 2 seconds, then it goes to a DOS LIKE screen, but only displays 8 or 9 characters in the upper left screen corner. Example: (A-UEVC=!!*e ) Once this DOS LIKE screen is displayed, it stays that way at every boot up. The only way I can get rid of it, is to unplug the RTC BATTERY, remove the Main battery, then start over. Then it goes to the message screen again, about going into the bios. But it only displays this ONE TIME. After that, at startup It goes right back the GIBBERISH in the upper left screen corner. This is a new one on me. Is there a way to reset the BIOS/CMOS? Can anyone HELP???? Thanks, Phil

Hi,yes there is but you'll have to open the system up,if you have no prior I.T expertise I'd suggest you take to a qualified Technician,but if you do here is how:First remove the Battery,then uncouple the system taking of where each of the screws go to then locate the CMOS battery(small battery Lithium Ion mostly in the shape of a cent or smaller),it may be underneath the keyboard or just behind once the external cover is open.unplug it from the system for about an hour or two reconnect it,couple the system and boot,go to Bios,reset Date and Time and save,then exit.
Check your settings in the display properties. The problem could be related to some display or power saver options. This applies if no reason means you do not touch your laptop when tthe problem appears. Otherwise it could be a wire problem as you have already supposed.
Assuming this is the same style of case as the older Portege models, the bezel on the bottom of the keyboard or on top between the keboard and the display should pry off (although there might be a screw or two into it around the hinge on the top) separately- they cap tabs on the edges of the kbd, or screws.
Probably, could have some slide catches at the top edge of the keyboard instead, need a thin blade screw driver oh lift the keyboard. Some laptops mark the screws with the letter K in indicate keyboard screws, some keyboard screws may be hidden under the battery pack, CD/DVD drive.
1. If the batteries are dead then there's no way that you can charge them again. You're better off purchasing a new one. You can purchase one online by visiting the ToshibaDirect website or by calling them on 1-800-316-09202.
2. Yes, you can use the power cords to run the computer. Just plug them in using the power cords even with the batteries removed and it should work fine.
3. Yes you can but you might experience some current fluctuations. This is negligible on a CMOS battery though.
Right click on the computer's destop and view the display properties. Under the tab where you can alter resolution you can manage multiple monitors, It sounds like your laptop is setup to display through it's external VGA by default. Click on the two squares it shows and try to set your main screen as default.
