I'm using an IBM Lenovo R52 notebook and an external SVA monitor. For reasons optometrists can't figure out, the notebook's own monitor screen causes me considerable eyestrain whilst the larger external monitor screen does not.
Anyway, there's no point in the notebook's internal monitor being active: It consumes power and emits heat. I'd like to switch it off. Alas! I don't know how. I've done the Web-search thing; but although this matter (in general) is quite frequently raised elsewhere, nobody seems to know how to shut off a notebook's internal monitor.
Please help! Your advice will be greatly appreciated and I thank you. (Kindly resist the urge to pass along advice such as "Close the lid." It's a bit difficult to access the keyboard that way!) Below are some system data.

look in the BIOs you might be able to set it to external only or FN + F7

Thanks, GMAC-R60, for your reply. Indeed, Levovo literature insists the F7 key enables switching between external and internal monitors; and it further states the correct key combination is (as you pointed out) Fn + F7. However, when I use that key combination the only result is that I'm presented with a dialog box enabling "Caret Browsing"; and the same box appears if I use the F7 key alone,
The F7 key itself even has on its surface a depiction of two monitors! The Web pages available via Lenovo Support & downloads - ThinkPad R52 1847-CTO support (link fails to redirect properly) contain no information pertaining to this problem. Oh, well.

you may not have the hot keys installed

Yay! Hooray! Thank you very much, GMAC-R60, for your advice. I installed those items you listed and now the Fn +F7 combination actually does what it's supposed to to! Your help in this matter is greatly appreciated. Y'all take care now, hear?
