Why won't my Lenovo laptop turn on, and which hole is which

By Alberto Gulotta · Updated 7 September 2026 · 14 min read

Why won't my Lenovo laptop turn on has an answer involving a paper clip and a small hole, and that is where it gets dangerous. Lenovo documents two different pinholes. They are pressed with the same gesture, they look the same, and they do opposite things.

Before either of them, though, comes the step Lenovo itself puts first.

If ten minutes on a wall socket changes nothing, then the holes. Here is what each one is, in the manufacturer’s words.

Read those three together and the shape of the problem is clear. One hole resets power. One hole opens a recovery menu. Which one your machine has depends on whether it is a ThinkPad or an ideapad — and the article describing the Novo button is marked, by Lenovo, as applying to ideapad.

Now the finding that is easiest to check and hardest to believe, because so much written about this contains a number.

Lenovo publishes no hold time for either hole. On its no-power troubleshooting page the phrase is simply “use a straightened paper clip in the reset hole to reset the system”; the ThinkPad manual says “insert a straightened paper clip into the emergency-reset hole”; the Novo article says to press it “gently”. None of the three gives a duration. On that troubleshooting page, read in full, the only length of time in seconds that appears anywhere is “at least 10 seconds” — and that sentence is written for the machines that have neither hole. An instruction to hold a pinhole for thirty seconds is not coming from Lenovo.

That absence reads differently next to a manufacturer that does publish one. ASUS documents a hold time for its own hardware reset, and is precise about it: “during the EC reset and RTC reset process, you need to press and hold the power button for 40 seconds”. It also publishes that the number is not universal even inside one brand — “different models may have either a 20-second or 40-second press design” — and describes what the shorter one looks like: “after pressing for 15 seconds, the power indicator will start rapidly flashing for about 3-5 seconds. After the flashing stops, release the power button.” Two things follow, and the second is the point of this page. A duration is exactly the sort of thing a manufacturer writes down when it has one. And forty seconds is an ASUS instruction for ASUS machines, not a number to carry across to a Lenovo pinhole — which is what every guide that supplies one for the Novo hole is quietly doing.

One inconsistency inside Lenovo’s own pages is worth naming, because it changes who this applies to. The troubleshooting page frames the reset hole as the alternative for sealed batteries: “Remove the battery if the battery is removable. For systems with an internal battery (not removable), use the Emergency-reset hole”. But the ThinkPad T470 bottom-view page lists [1] Removable battery and [5] Emergency-reset hole on the same machine. So the hole is not confined to laptops with sealed batteries, and a reader who checks for a removable battery first may conclude the hole is not for them when it is.

A note on where this question gets answered, and on a limit of this note. Google returned an anti-bot page rather than results when this was written, so the reading below is from Bing, in the United States, on 23 August 2026. Lenovo’s own no-power troubleshooting article is easy to find, so this page makes no claim that the manufacturer is absent from the results read. What is missing is narrower and checkable: the Novo button is named repeatedly and the emergency-reset hole is not named at all — which is the conflation this page exists to undo, since the Novo button is an ideapad control and a great deal of the audience is holding a ThinkPad.

What this page will not do is tell you to open the laptop. Some results for this question suggest removing RAM or the drive; none of the Lenovo documentation read here asks for that, and the pages that do are not the manufacturer.

It will not give you a number of seconds for the pinhole. Lenovo does not publish one, and inventing a duration that sounds authoritative is exactly the habit that makes this question so confusing.

And it will not tell you which model you have or where your hole is. Lenovo’s own instruction is to look: “refer to the page that shows the bottom view in Product Overview section in the User Guide”.

Not covered here. It will not tell you to take the laptop apart. The Lenovo pages read here never ask for that, and results that do are not written by the manufacturer.

It will not print a hold time for the pinhole. Lenovo publishes none, and a confident number from somewhere else is a guess wearing a uniform.

It will not tell you the machine is dead. Lenovo publishes at least one case where refusing to start was a BIOS defect with a fix, so a diagnosis from a page you are reading is worth nothing.

And it carries no affiliate links, including for the data recovery services that advertise heavily against exactly this question. What holds instead is simple: every instruction here is quoted from Lenovo, the two holes are described from two separate Lenovo pages, and where Lenovo publishes no number this page says so rather than supplying one.
