SOLVED: VIDEO: Lenovo Laptop Will Not Power Up, Flashing Power Light Problem

If you have a Lenovo laptop with a flashing LED on the power switch but will not power up, we have the fix.  This short video shows a quick disassembly of a Lenovo Flex 3 1430.  You can then unplug the battery and solve the issue.

In theory, holding the power button down (5 seconds on a PC or laptop, OR 15 seconds on a tablet) will force the unit to power down.  However, that does not always work and so you need to pull the battery.

    Hi guys,

    So i have a lenovo z710 and I just bought a new motherboard for it. I have disassembled it and reassemble it, with each component I added it still gave me the same issue (blinking power light) and it would not turn on. I hope you guys can help.

      Sorry Humam; At that point you may have a failed CPU or motherboard 🙁

    Using a small paperclip worked great! I am sooo glad I didn’t take my whole laptop apart!

    Hi VIrendra, I also have a T480 and the same symptom. Actually there is a easy fix, if you look carefully at the back of the laptop, there is a small hole which you can use a needle or iphone pin to push through, its a reset button in it. Hope it helps 🙂

    Hi George
    I have Lenevo T480 Laptop, with similar problem (Flashing LED Light at Power button and keypads keeps on blinking, but laptop unable doesn’t start). As in this model, Battery is externally attached, I can easily remove and put back. I did that, but my problem is still un-resolved. Any other reasons for this , which part should I check. Pls guide.

    I only want to add a side note. Taking the batter out is always recommended when dissembling a Laptop. It doesn’t matter if it’s completely powered off or not. The battery should be taken out as a safety measure.
