I just got a kingston 4gb ram stick the other day. i installed it into my lenovo thinkpad L512 and it wont book up. i tried it in each of the two ram slots with the other ram out and it still wont start. I know the computer can hold up to 8gb of ram but i have no idea what to do.

How old is the laptop, your new RAM may not be compatible with your laptops motherboard.

Forexample if your new RAM is DDR3 and your old was DDR2 then it most likely doesn't support DDR3 RAM

All this informations including RAM's clock rates (1333MHz as an example) are displayed on the label on the RAM sticks

Let me know if this helps.

i inserted it correctly if that is what you are asking. i even put the one that came in it in multiple times to make sure it wasnt the ram slot that wasnt working. when the 4gb is in it turnes on and comes to a screen that gives me the option to repair windows or start normal. if i clisk start normal it restarts and goes back to the same page. if i click repair it says windows is loading files. after loading bar gets all the way it goes to a black screen and the fan just keeps going on high. i left it for two hours and nothing happened. both sticks look identical

Ok i made this a while back for my friend, so here's a quick troubleshoot:

Solution 1

The RAM is not seated properly! This could be the reason that your laptop is not booting up after upgrading with a new memory module. I faced exactly the same problem initially. Following are a few simple steps to insert the new memory module(RAM) properly.

Once you have removed the old RAM and ready to insert or install the new RAM, then the most important thing you need to know is that the angle at which you insert the new RAM. Most of them who are new to installing RAM tend to insert ram in a horizontal / completely flat direction, which is a wrong method; because, in this way, the RAM doesn't get into its place, no matter with how much pressure you push it in.

The correct method is to insert it at an angle of 30-50 degrees. Tilt the RAM slowly at an angle of 30 degrees while inserting the RAM and when properly positioned, it will get in easily and instantly. It is after this that you need to press the RAM down firmly so that it's placed within the retaining clips firmly. Now put back the battery, plug in the power cord and turn on your system. You will now notice the system will boot up successfully without blinking of two lights.

Solution 2

Swapping the RAM from one to another has worked for many. If you have two slots then swap one to another and try rebooting.

Solution 3

Either the slot or the RAM could be faulty. In order to check this, lets start with RAM. In order to know whether the RAM is at fault or not, try inserting the RAM in the other slot, if it works properly from another slot, then the problem is with the first slot. Second possibility is that the RAM itself is damaged. Insert the RAM in the other slot and boot up the system, if you still get the same blinking caps lock and lock button error, then probably the ram is damaged.

Apart from the above fixes, there could be other issues as well depending upon the brand and models of various laptops. However, the solution is the same for all models, provided you are facing aforementioned problem. If nothing works for you, then explain the problem, you are facing in the comments section below.

Other than testing the RAM on start-up there isn't much you can do but say the RAM's faulty

(Although its extremely rare for new RAM not to work straight from the anti-static bag these days as they are made within a factory that is about 100,000 times cleaner than an operating room.)
 
Have you physically checked in the bios of the laptop.
That the values stated on the new 4gb stick are set right.

When you change a stick of memory.
You need to check the bios has set the speed correctly, and the timing settings for the new ram module and the voltage.

Sometimes this is required, because the old values of the old memory are not refreshed. And must be set manually by the information on the new memory stick.
