The keyboard is connected to the mainboard via a ribbon like connector. A keyboard is actually a matrix of contacts that are linked togheter via some 5-6 lines. If one of this lines fails (broken contact, a connector that got loose) an entire area of keys will stop to work. You may recognise connector problems of such type by looking carefully at the keys that don't work. You may find that the non working keys form lines from the top to the bottom. For example if you find that the "q" key isn't working, then the "a" and "z" and "alt" may not work as well. For "w" key, the coresponding line is "S" "x" "\" and so on.
In order to fix this problem you need to dissasemble the laptop and check the connection between the keyboard and the motherboard. If you have some tools (small screwdrivers mostly) and some basic knoledge about dissasembling electronic things I will assist you through the process. Please reply back if you are willing to try to fix the laptop on your own and I will guide you through the process. Otherwise, a service center may be able to dissasemble the laptop and check that connector or the keyboard for a small fee.
Please reply back when you make the decision to either repair it yourself or let a service center do the job. Good luck.

there is no best. unless you stated. what it is to be used for.(application, job, what?) 1: works (sure they do) but some huge ones do not work on really old PC or camera's. 2: or speed. 3: sizes, no job stated (usage) so no guess.
what you need we have no idea at all. if saving video files speed matters? if saving say only email, then small slow works ok.
your usage or applications, matter what you need. they sell these at walmart, just buy one and be happy.
buyone $5, if not work take it back get another until happly.
Hey, If a few keys do not work on your keyboard you can get them replaced , i recently got my new replacement keys from www.laptopkey.com Now my laptop keyboard is as good as new. Love them for they service and reasonable cost.
The easiest way to do what you want is to buy a USB keyboard. Some Dells have ps2 connector and you might be able to use a ps2 keyboard. The ps2 connector will be on the back and is round and has holes going in a circular patterns.
if they are relly broken you need to buy a new keyboard. depending on the type of your inspiron you should search for a new one like this http://cgi.ebay.com/Dell-Inspiron-2600-2650-Laptop-Parts-15-Keyboard_W0QQitemZ270256807128QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3eec8f9cd8&_trksid=p3286.m20.l1116

If the keyboard is locked ALL the time, try unpluging the power supply, remove the battery, then push and hold the power button and any key on the keyboard for at least 30 seconds. then reinstall the battery, plug the pwoer cord back in and reboot it.
I had the same problem and that is what the DELL techs had me do. I had the problemm frequently for a while and then it just quit recurring. I haven't had the problem for a long time now.
