To carry out this upgrade, first disconnect the mains and the battery. This is to prevent any stored stray current from damaging the RAM. Next, touch any metal surface to dischage any static current from your body. Remove the two screws at the bottom of the S10 and pull out the cover. You will see the installed RAM or the empty RAM slot on the right, depending on what size of memory came with your unit. On the left is the HDD which you can also easily upgrade if you so wish.
If there is a RAM istalled, spread the securing clips on either side of the RAM and it will pop up at about 45 degrees.
Carefully remove this RAM and inset your new RAM into position, at about 45 degrees slope. Press down the RAM until you hear the click of the securing clips and you are done. If not, spread the clip and repeat the whole process.
When you put back the cover, press down firmly at the threee palces where there are catches. The cover may not be flushed initially but once you tighten the two screws, it should be.
You can check the amount of memory you have by going into the System Properties. To get there, go to the Control panel > Performance & Maintenance > System, or from My Computer > View System Information under System Task. Near the bottom of the System Properties you will see the size of the memory reported.
In fact Lenovo has a series of video if you want to carry out more modification to your S10, though they are meant more for service personnel. Anyway, they can be found here, courtesy of skyhook59 in the Lenovo S10 Forum. With these you can take your S10 apart and (hopefully) put it back together again. But do be mindful that certain modifications may void the warranty of your S10 so check with Lenovo first.
For those less adventurous, here's just a tour of the various indicators available on the S10. There are three LED's at the front. The first is the power indicator which will be blue when the S10 is on either on AC or battery. The second is the battery indicator. It will be orange if the battery is charging and blue if the battery is fully charged. The third is the wireless indicator. It will be blue if WiFi is on, orange if Bluetooth is on and purple (blue + orange = purple) if both are on. These will flicker when there is any wireless activities.
If this is not lit at all, check that the wireless function is switched on by pressing the green wireless button next to the orange One Key Recovery button on the top of the keyboard. Once the wireless is on, you can select either the WiFi or Bluetooth or both to be on by pressing Fn F5 to access the wireless setting window below.
If you are not using any Bluetooth devices, it is best to turn Bluetooth off since it will save you some battery power.The other three indicators are found next to the power-on switch at the top of the keyboard. They are the CapsLock, NumLock and HDD indicators. Of particular interest is the NumLock. For some strange (and unknown) reasons, the NumLock is enabled when the S10 is first switched on, out of the box. Not sure even if the NumLock light is on or not in this first instance. Because of this, it has caused a lot of frustration to user who had problems connecting to their secured wireless network for the first time. This is because the NumLock is on unknowingly and when one keys in the security or authentication key it will be wrong if the digit 0 (zero) is used as a / (slash) will be entered instead. (The slash is on the zero key - top row of the numbers - and will be entered when pressed if NumLock is on.) Users will not know since all you can see is just ********** as the key. Of course they cannot connect to their wireless network since the security/authentication keys do not match.
So if you have problems connecting to your secured wireless network (or entering other passwords), first cycle through the Fn F7 to make sure that NumLock is not on. After the first switch-on, the Fn F7 will function normally. It will be interesting if users can feedback any other quirks they find on their S10 in the comments.
