Rectify.IT – Fujitsu Lifebook P8110 Scroll Lock flashing

On Saturday, while doing a few things around the house, amongst other things – I was checking to see whether or not I could get a second drive caddy for my Fujitsu Lifebook P8110 notebook.  I was trying to remove the DVD drive and at the same time, decided to take all of the covers off the bottom of the notebook.  One cover hid a mini PCIe socket which I believe is for an optional wireless card – or perhaps even a small SSD.  Another slightly larger cover hid the memory socket, in which was installed a Kingston 4GB DDR3 1333 Sodimm, and of course the much larger cover was for the internal hard disk drive.

In due course, I put everything back together and put it back into my backpack since I use it for work as a Windows 10 machine from time to time.  To my surprise this morning, it failed to power up – well, actually the power light came on, the disk light came on then the Scroll Lock light started blinking.  I could still hear the hard disk drive spinning.  There was no display at all, not even the Bios POST screen came on.  I held the power button to force it to power off.  I did this a few times to confirm that I was not imagining it and eventually put it back into my backpack and went on with my tasks using my work laptop.

After coming home, and watching a short movie, I got my Lifebook back out and tried it again – the same flashing Scroll Lock light.  A quick check on the internet showed no solutions however one site did say that it may be power related.  I eventually got the battery removed, and connected the power adapter and still the same.  One site did suggest memory – and yes, I did remove the memory module on Saturday, so could this be it?

I opened the cover and removed the memory – a 4GB module as described above.  I had the laptop screen down and the main body up – i.e. the laptop was open so that I could reach the power button and see the screen but could also access the memory slot.  I pressed the power button, and the Lifebook came to life, as in the Bios screen came up then proceeded to boot to Windows.  I powered off and went in search for some memory.  I had another Kingston 4GB so tried that – no go.  Then I found two new Kingmax 4GB Sodimm’s and tried one – and yes, it worked.  Afterwards I decided to try the original memory – the first Kingston 4GB and while putting it in, I latched and unlatched it a few times since it could be just a contact problem.

So did it work, I can hear you all asking?

Yes, the notebook booted up!  I shut it down, then put the cover back on, then put it right side up and powered on.  Still working, so it appears that the flashing Scroll Lock light is indicating a memory problem.  The motherboard has 2GB of inbuilt memory, so the notebook will boot from this, and my 4GB brought it up to 6GB – more memory of course, is better for Windows 10.  At least I know what to do if this happens again.
