Thinkpads Forum

Hello,

I would have two questions:

1.) I know that the blue Access IBM button has different functionality. However, something is not clear for me. When I press it during the boot process then it invokes the BIOS sometimes or the Rescue and Recovery sometimes. I could not determine the rule. Does anybody know it? My laptop is an R51E model.
It is very uncomfortable that I wanted to enter to the BIOS but the RR console booted (and it was long) then again then again and then the BIOS appeared. Next time I wanted to use the RR console but always the BIOS appeared.
Any help would be appreciated.

2.) I use the R51E without battery pack. I mean I attach it to the charger every time but the battery is not attached to preserve the life span. I read somewhere, that it is not good for the electronic ... what do you think.

Thank you very much, indeed.

Regards

To access BIOS you can press "F1" during boot-- my ThinkVantage (same as AccessIBM) button always goes to RR if the partition is installed.

I don't think you can hurt the system by running it without a battery installed. The only negative is the possibility of lost data/work if the cord were to disconnect.

Thank you for your response. Regards: emts

Hello, welcome EMTS.

Just my two cents, but I know with my Dell PDA it is highly advised to never run the thing on AC power alone, with the battery out. That battery evens out the AC power coming into the circuitry. I did find this snippet on battery care for laptops, sort of suggests the same thing:

"A battery that is not used for a long time will slowly discharge itself. Even with the best of care, a battery needs to be replaced after 500 to 1000 recharges. But still it is not recommended to run a laptop without the battery while on ac power -- the battery often serves as a big capacitor to protect against voltage peaks from your ac outlet."
