Laptop has issues booting - keyboard flashing (Lenovo IdeaPad Flex 2)

Hello,

 

My parents have owned a Lenovo laptop for a couple of years now. However, recently this issue showed up and I wondered whether there is a chance there is a solution to this problem which I could try myself, since the laptop its warranty already expired.

 

If I recall correctly, the model of the laptop is the Lenovo IdeaPad Flex 2, running Windows 10.

 

So here is the issue; the laptop has issues turning on. Oddly enough, it is not a very consistent issue. Eventually, the laptop does turn on. The problem is that this sometimes takes hours, other times the laptop appears to be able to boot instantly as it normally would. I have no idea what affects this.

 

When pressing the power button, the keyboard backlight starts flashing. It does this until the laptop completely boots, and as I said, the amount of time this takes varies.

 

I already tried looking for solutions on different forums, but they usually concern the issue where the keyboard backlight flashed and the laptop simply will not boot at all, which is not the case here, as it eventually does but often it takes a while.

Other solutions suggested a certain amount of flashes meant a certain issue or failure. Problem here is that the amount of flashes seem to be random, so it is not as if it just keeps looping a certain amount of flashes as it varies. This leaves me puzzled as to what could be the culprit.

 

I am not sure what to do, especially since I have not owned a Windows-based machine in a while. The issue seems to occurr when the laptop is fully charged as well, and it makes no difference to whether it is connected to an outlet or running on battery power.

 

I am sort of afraid this could be caused by some hardware failure and there is no other option beside getting it repaired, but as it is out of warranty I just wanted to make sure there is no chance I could fix it by myself.

 

Thanks!

Hi itsasin,

 

Welcome to the Community Forums.

 

Would you have the machine number or MTM to verify the model (you can also get from here)?

 

Isolating the point of failure may be necessary to determine if the delay on start up is a power issue or a boot problem.

Try removing the harddrive so we can test if the machine can power faster.

You can download the hardware manual from the support website for removal guide.

 

Update us how it goes.

 

Regards

Re: Laptop has issues booting - keyboard flashing (Lenovo IdeaPad Flex 2)

Hello,

 

I just checked the back and it is apparently a Flex and says;

- Lenovo Flex 2-15

- model name: 20405

 

I am not very comfortable with tinkering with any hardware inside, especially since it is not my laptop.

 

If I were to manage to remove the drive, then what exactly should I do? If I remember correctly, this is not a mere HDD but a hybrid drive, and the OS is on the faster storage part.

Hi itsasin

 

Greetings.

 

You can take the time to review the hardware manual here as it would give you an idea how disassembly would be done.

The flashing may indicate several things and to isolate the point of failure we can first narrow down the processes.

 

Was it a windows boot issue or a deeper issue with the hardware especially with the systemboard, CPU, memory, video chip and others? To do this, if we remove the harddrive then we eliminate the software and harddrive issue as the machine should complete POST (power on self test) to indicate a functioning mechanical systemboard and main components. 

 

A good POST would show a responding menu with a display onscreen that would indicate a good systemboard especially if you can access the BIOS (FN+F2 during restart).

 

A hybrid drive is much similar to a typical harddrive even if this is a solid state drive. The machine should turn on with functioning display without it.

 

If you do not have the tools or not comfortable removing the harddrive then you can have it checked with any local service centers that would do isolation of the issue. Flashing lights may indicate attempts to start booting to Windows just like a failing loop or it may also be a systemboard failed POST.

 

Update us how it would best work for you.

 

Regards

Re: Laptop has issues booting - keyboard flashing (Lenovo IdeaPad Flex 2)

Hello,

I ran into a little issue while trying to open up the laptop. It did not seem like a difficult process at all, and I easily got to remove the keyboard, removed to necessary screws at the back and also the optical drive space et cetera.

However, in order to actually open the back, I just had to remove one last screw from underneath the keyboard, and it sort of got stuck. It was screwed in so tight that I basically screwed up the screw and now it seems completely unwilling to move. Problem is that the cross head, or like let us say the metal part, is not quite a cross pattern anymore and whatever screwdriver I try to remove the screw with, it refuses to budge since it became a complete mess.

I asked my dad whether he had some tools that might get the screw out, like gripping it with a set of pliers or something, but the ones he owned did not seem to be able to do the trick and now we are kind of left with this one screw preventing me from opening the back case of the laptop.

If I were to get the screw loose, I would at least be able to recover the SSHD and possibly recover its data, but now I cannot even seem to do that anymore because 1. I am unable to open the laptop at this point and 2. the laptop seems unwilling to boot anymore whatsoever (I tried for nights on end, and it did nothing at all).

Hi itsasin

 

Greetings.

 

I usually use rubber band over the stuck screw but if needed, service center does have tools for such event. Likewise, they would be able to test further on the issue as mentioned previously.
