Makita 6935FD has lost all torque. The drill varies speeds when not under load, but won't drive a screw. The battery is charged. If I get the trigger in just the right place the drill will hammer once, but then it stops. This has been a great drill. What is the most common problem?

Return it to the place of purchase if under a year or send it to Makita UK in Milton Keynes

I think your battery is died. I suggest you can replace a new of this battery for your drill.

could be a problem with the impact hammer, I would suggest removing the front housing to make sure not sticking or hung up on the anvil. Make note of how you remove the gear housing to you can reassemble. Also you might want to go to makitausa.com first and download a breakdown for the tool

Check what gear you in, the Makita will smoke if you exert to much torque, consider buying a decent impact driver? If its not under much pressure then it may be a fault with the drill. I have owned one and it was reliable but sometimes under-powered for an 18volt compared with others on the market.
Hope this helps

Sounds like the battery never fully charged and lost all capacity to do so. You can get on ebay and get one or find an interstate battery distributor. Sears.com also has access to these batteries.

did you check the battery under a load condition?as in check the voltage under drill operation,most batteries will check their normal top charge voltage when not being used,this is known as a surface charge,but under load the voltage may severly drop leading to burned or overheated armatures,have it load tested

I would recommend going to Makitatools.com and typing in your model number for a schematic. Basically all you have to do is remove the 4 screws on the front holding the gearcase and then remove all the other screws holding the handle halves together. Let me know if I can help

Batteries are definitely still available. I haven't priced one recently, but if you do a google search for 7.2v Makita batteries, you'll find what you're looking for.
On the other hand, for the price of a couple of batteries for that drill, you're well on your way to a new drill and batteries. Nowadays, with lithium ion battery technology and major advances in the drill motors, you'll find a new drill has a lot more torque and holds a longer charge. They also put lights in the front, which are very cool when you're under a sink in the dark trying to screw something in. It depends, I guess, how much you use it, and what for. Do you want to be able to drive 3" screws into framing lumber without a pilot hole? Maybe not.
There are times when I use my 12v impact driver all day and can't imagine trying to make do with my old 9.6 v drill, but I still keep it at home, for just in case. And makita is still tops in my book.
BTW, here's a link to a downloadable .pdf manual for your tool. Makita 6019DWE
