Now what? Get set ready to start looking for the exact reason for making your Lenovo máy tính not turn on. If you have already found out the cause, then jump on the exact fixes.
Let’s start with the easiest basic troubleshoot when your brain keeps triggering you with the question– what to do when Lenovo máy tính is not turning on!
When I find my Lenovo máy tính is not turning on at all, the first and foremost thing I check is the power. Is it getting the proper power source? Is the máy tính fully charged or not?
Have you checked it? No? Then, check and ensure first maybe your máy tính is having trouble with getting the proper power.
When you find your Lenovo máy tính won’t turn on no lights beside the adapter cable ports, it means the máy tính is not getting power.
At this point, the first thing that comes to check is the power source.
Have a check on the wall outlet. Are you forgetting that the cable is loosened from the wall outlet like one of our team members faced the same once?
The wall outlet socket was a little loose for the adapter power port, and he just cursed the adapter as faulty with no light on. How silly a mistake sometimes the experts can make!
So, make sure you are also not doing the same.
Then, check there is not any voltage down at your place. To be sure of this, perform a lamp test, the most straightforward way to check the voltage issue of the primary circuit.
Don’t you know what the lamp test is and how to perform this to check the main power?
If yes, then there is no issue with the main power source.
But if no, then quickly call in your electrician and tell him to fix this.
Power source from your wall outlet okay? Then, gradually go with checking the cables and adapter.
Make sure there are not any bents in the cables or any tangle. You know a tangle or invisible defect in the cable can sometimes cause trouble in the power flow.
So, better to check the cables and cords very well. Also, check if the AC adapter is well and working well. Look, there should be a power status light beside the adapter ports on the máy tính.
No status light indicator? That means your Lenovo máy tính is not charging or turning on. Then, the power adapter might be faulty.
Can’t you be sure about the máy tính charger adapter? Then, test it. What can be better than pushing yourself if you have a digital multimeter.
Do you have one? Trust me; it’s super easy and interesting to test if you are a Physics student or interested in electronics.
But this can turn into a boring test if you are hazy with checking your máy tính AC adapter and do not want to put yourself with the steps to turn on your máy tính without spending bucks.
Try it, and maybe you can save your bucks or the one you will be getting for taking the máy tính to the repair center.

What you need here is a digital multimeter and the battery adapter cables that you use to charge your Lenovo máy tính.
Figure 1-Multimeter
If you need, try this cheaper AstroAi Digital Multimeter perfect for the newbie troubleshooter.
Notes: If you’re not sure, check the manual. But don’t short out the cables with zero knowledge.
Figure 2-multimeter reference guide
Notes: If the pin inside the port is not accessible, insert a small pin and make the probe in contact with that pin.
What is reading? Is it giving a reading of 20V or near to that?
Then, no issue with the AC adapter. Check for other fixes.
The rule of thumb says, generally, this reading should be 18.24 to 19.76 Voltage.
So, if the reading shows less than 18V, you need to replace the battery adapter with a new one.
If you already have done this, then have a quick check on the AC adapter cable also. We mean the cable that connects the adapter from the main socket.
Notes: Keep in mind here the pin in the middle is the neutral pin that you don’t need to bother with.
But if the reading is less than the standard, then replace the adapter cables.
Then again, if the Lenovo máy tính is not turning the power light on, be sure it is getting the proper power. And so the problem is something else.
Are adapter cables okay? Still, your máy tính is not turning on Lenovo?
Also, when you see the Lenovo máy tính not turning on and not charging the problem can be with the battery.

So, let’s see how to do a force reboot.
Is it on?
Not turning on? Don’t waste time. Move on to the next diagnosis.

Before proceeding with checking the battery, at first try hard reset to drain out the residue power.
Maybe your Lenovo máy tính is not turning on because of the static power clog inside the internal battery. The power clog is a residue of power stored in the capacitor.
Modern computers sometimes don’t drain out all power even after switching off. Some power residue still remains that might create an electricity clog in the capacitor leading to the máy tính not turning on.
So, draining out that power can sometimes resolve this. Especially if you find your Lenovo ThinkPad máy tính not turning on, this method is a must-try first.
Is it turning on? Bingo!
But if it is not turning on then,
Remove the battery. Try to turn on the máy tính using the adapter only. And see if your Lenovo máy tính turns on or not.
If it turns on using the AC adapter only, no battery inside then, you need to replace the battery. But you can be very sure about the battery if you insert another battery and try to turn it on.
Again, the battery might have no charge at all, so the máy tính does not turn on. Connect the battery and leave for a couple of hours to let it charge. Then, check if your máy tính Lenovo is turning on or not.
However, if you have never removed your máy tính battery before, then
If you are a newbie with your máy tính, check this Lenovo Thinkpad external battery removal guide.
Try power drain using the emergency reset button if the battery is non-removable or the internal battery.
So, check there is an emergency reset button on the back of the máy tính.
Do you want to check your non-removable máy tính battery? You can remove it to check or replace the battery but the thing is you have to be a little techie expert.
Not that much, just a little knowledge with the screws and nuts.
Finally, if possible, remove the battery and try turning on inserting another battery that you are sure is in good condition.
Now, try turning on your máy tính. If it turns on then, you just got your culprit- the battery. It needs replacement.
Things to be noted, if the battery is the only problem, your máy tính will turn on using the AC adapter without inserting the battery.
That means if you find your Lenovo máy tính turning on without battery that also gives the signal to a dead battery.
