How to solve laptop problem 'failure to boot' after upgrading RAM or memory

In this article, you will learn how to successfully install or upgrade a memory module(RAM) on a laptop. If your laptop fails to boot up after installing new RAM or if the system boots up with caps lock and lock button blinking for 30 seconds before shutting down completely, then here is how to fix this issue by following few simple steps.

I have a Dell laptop of latitude series which has 1GB of inbuilt RAM. I wanted to upgrade the memory for faster performance and to avoid frequent struck screen due to increased RAM/memory usage. My laptop has two slots, one underneath the bottom of the laptop and another hidden under the keyboard. So here is how I came across with the above mentioned error and finally managed to sort it out successfully. Now I am sharing the same with others at Techulator.

Is your laptop not booting up after upgrading RAM?
Is your laptop not recognizing the new RAM?
Are you facing the error in which caps lock and lock button blink for 30 seconds before shutting down?

If you are facing any of the above problems after trying to upgrade RAM, then here are a few solutions that may work out for you as it did for me.

Before starting the steps, turn off the laptop completely, remove the power cord from the main power and battery from the laptop. Remove the plate covering the ram with a screw driver. Now you can follow the below mentioned steps.

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

You may be getting the error because your laptop doesn't support more than 1GB. There is no solution for this.

Solution 3

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 4

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.

Thank you so much! I got so worried when changing my RAM from 1GB to 2GB. It did not work and then I tried putting it's 1GB back but it still didn't boot. I thought I had damaged my Samsung NB 30. However, on coming across your article I was able to put the 1GB Ram back in & that made it work.

Then why would two different modules show the same as in Solution 4 (caps lock flash at forced shutdown)? The other stick I tried was the one upgraded from that worked perfectly to that point.

Now am stuck with the single soldered on 4GB RAM in my Samsung Series 7 Chronos notebook. What a bummer, a nice quad core i7-3635QM (4 cores, 8 threads), only to have that performance stiffed by the slot not working. Am afraid to try more modules, may blow these upon boot.
