It happened to me already couple of times: in shooting mode A can't get underexposed pictures using exposure compensation dial. Just in case I found a pretty big table with restrictions on camera settings on the back of manual. There is no particular mention about any restrictions on exposure compensation, why would be anyway it wouldn't simply make sense... unless I am not aware of something. I shoot with 7D, and I am new to Fujifilm world. Any idea what is going on?

I'm guessing that you were trying to exceed the maximum shutter speed. Because of the leaf shutter, the maximum speed for the shutter depends upon aperture selected. Wide open has the slowest shutter speed and this gets faster the more you stop down.

Nope.It was a bright day. It would take normally exposed picture and yes, if I would try overexpose it may be a problem with shutter speed but it wouldn't let me take underexposed picture with ISO 100 and slower aperture. it simply didn't work....

You're probably running into the shutter speed restriction that limits how fast you can make it in Aperture Priority mode, because it's limited by the selected aperture. On a sunny day if the aperture is too wide you might see the shutter speed turn red in the LCD display, indicating that the shutter speed won't go any faster. This limit depends on a lot of factors, including not only the aperture selected, but also the focal length you're using. The DR and resolution (L vs M) may also have an effect. At the widest aperture you might see 1/1000th sec. appear red, and if you try to give it some negative EC, nothing happens because the X10 won't allow a faster shutter speed. As you close the aperture you'll change the shutter speed limit, which will now allow 1/1200, 1/1500, 1/2000, etc.

Don't ask me why Fuji does this, because it has lots of interdependencies. For instance, with most of its EXR cameras (I haven't specifically checked this with the X10) when you're shooting at night and it's really dark, you'd think that with the camera on a tripod you could use a really slow shutter speed and a high ISO to get a good exposure. But in really low light, Fuji links the shutter speed with the ISO level, so if you raise the ISO by one stop, the slowest allowed shutter speed changes by the same amount, so the exposure doesn't change. The Canon P&S cameras that I've tried don't do this, and the Nikon P&S cameras are somewhere in between.
 
Would setting the camera to Manual mode give you the result you want?

wow! That means there are restrictions! Not that I am complaining about just not used to that being spoiled by using DSLR cameras. I have never bumped into this problem before. Thank you for explaining. I will have to learn that camera which otherwise is great and totally new experience in photography for me.
 
As noted above, the X10 uses a leaf shutter, not a focal plane shutter like your 7D. If you don't know the particulars and differences between leaf and focal plane shutters, do a quick google search of "leaf shutter" and you'll find wikipedia articles and other references.

There are advantages to a leaf shutter, the most often quoted being that flash synch is possible at all shutter speeds, something focal plane shutters can't do; quite useful for fill flash in bright conditions. Among other advantages, they're much quieter (useful for surreptitious shooting or in quiet environments), they don't impart subtle distortions on moving objects, etc.

However, leaf shutters are limited in maximum shutter speeds due to how they work. In a nutshell, the larger the aperture, the longer it takes the leaf shutter to open fully to accommodate the selected aperture and then close. Ultimately, there's a mechanical limit which is why the fastest speeds are only available at small apertures (large f-stop numbers) since the shutter doesn't need to open as far under those conditions.

Once you've reached the mechanical limit, that's it. Regardless of what shutter speed you've commanded on the dials, the shutter ain't gonna close any sooner. In your case, underexposure is impossible because the shutter can't go any faster. In other cases, you could get overexposure because the shutter can't close fast enough.

It's just the way it works. I read somewhere that you should view the higher shutter speeds available at small apertures in the X10 as a bonus rather than seeing the limitations at large apertures as a failing. Some cameras with leaf shutters don't offer speeds faster than those available at wide open apertures ... no funny limitations, but no higher speed shutters either.

In any case ... yes, you'll need to study the way the X10 works to get the best out it much as I'm sure you had to study your dSLR cameras to get the best out of them.

Very interesting. Thank you for explaining however it goes into the rocket science a bit for me. I am happy at this point that there is nothing wrong with my camera. :)
