Acer BIOS password recovery, by model number

Turn the laptop over. The model number on the label looks like PH16-71 or AN515-58. Find yours below to see whether we can help and what it costs.

Found your model? Start recovery.

Why the number and not the name. Acer sells the same marketing name with different hardware inside. A Nitro 16 is an AN16-51, which we can work on, or an AN16-41, which is AMD and which we refuse at any price. No model number in the research behind this page shipped as both Intel and AMD, which is why the number is trustworthy and the name is not.

Find your processor first

Press the Windows key, type About, open About your PC and read the Processor line.

  • Core Ultra: the Core Ultra tier below.
  • Otherwise the first two digits of the model number are the generation: i7-13700HX is 13th, i7-1165G7 is 11th.
  • AMD, Ryzen or Athlon: refused, at any price.

The model line (Predator, Nitro, Aspire, Swift, TravelMate) does not change the answer. The processor generation does.

Covered: $70 with a proof of purchase, $120 without

Intel Core 12th, 13th and 14th generation. Usually done inside 24 hours. Two of these have been recovered and confirmed; the rest share the platform generation, which is the thing that actually decides it, and are marked as inferred until a capture from one reaches us. How sure we are explains each grade.

Core Ultra: $150 with a proof of purchase, $200 without

Taken on like any other job, at a higher price and up to 72 hours. Core Ultra is a different processor family from Core i7, not a newer version of one, so a brand-new machine sits further from the cheap tier rather than closer to it. None has been through the whole process here yet.

11th generation and older: $100 with a proof of purchase, $150 without

Also taken on, also up to 72 hours. Older machines need more work per model before an attempt can be made, which is what the price and the wait cover. Many machines this old show a code on the screen instead of writing a file, and if yours does, stop here: the free unlocker answers it in seconds and costs nothing.

These need the report before anyone can say

One model number, two different machines inside. Either Acer shipped both an Intel and an AMD build, or the same number spans the edge of the covered window. We will not guess on your behalf, because guessing here means quoting you a price for a job that cannot be done. The report from our tool settles it, at no charge.

Model numberSold asWhy it is not a straight answer
EX215-57 Extensa 15 Spans three families, 15W and 45W. Some configurations are 13th gen H and covered; others are not. The full model string decides it.

  • Acer Chromebooks. Different firmware. The community project MrChromebox is the place to look.
  • Acer desktops (Predator Orion, Nitro N50, Veriton, Aspire TC). Different firmware; this is laptops only.
  • Not running Windows, or no administrator account. The tool is a Windows program. The password lives in firmware, so installing Windows would bring the machine back in scope, but that is your call.
  • Windows will not start. There is nothing to run the tool on. A BIOS password normally blocks only the F2 screen, so if Windows will not start for another reason, tell us what happens.

Older Acers that show an 8 or 10 digit code on screen are not refused: they need no service at all. The free unlocker answers them in seconds.

How sure we are

A result we have produced ourselves does not read the same as one we expect. Every class of machine we have an answer for, and how strong that answer is.

verified

Recovered by us on that exact machine and typed in successfully at its own password prompt, more than once, including a blind test with the password withheld from the person doing the recovery. One machine is in this grade.

corroborated

Not our own result. Either someone unconnected to us described the same thing on that board, or our free generator has been checked against a separate implementation of the same old scheme, written by someone else. How strong that check is varies by row, and the note in each row says so: some rest on two independent authors, some on one, and on two formats the usual reference is itself wrong and we deliberately do not match it.

inferred

Same platform generation as a verified machine, which is the thing that actually decides it. That is a reasonable prior rather than evidence, and most enquiries land here. We expect it to work and will not pretend it is proven until a file from such a machine reaches us. You pay nothing if it does not.

served

Taken on and quoted like any other job, but no machine of this class has been through the whole process here yet. They need more work per machine, which is what the higher price and the longer wait cover. Not a refusal, and not a queue you are waiting in.

no

Refused, at any price. Sending a report will not change the answer, though you are welcome to if you would rather hear it from us.

Dell's newer service-tag scheme (595B, D35B and the rest) is not covered yet. This one is also our thinnest evidence: the only second implementation of it reads uninitialised memory and returns a different answer every run, so it is checked against one author's code rather than two.

Three of the five formats are confirmed by two independent authors; the two 20-digit decimal schemes have only the single reference implementation. On one format the reference itself is wrong about letter case and we follow the original research instead.
varies by format Open the free unlocker corroborated

How the stored value is built and where it is kept is not published, on this site or in the tool. That research is the service.

Your model is not on this list

That is not a no. This page lists the model numbers the research behind it could evidence, and Acer ships a great many more than that. If yours is an Intel Acer laptop that still starts Windows, it is very likely workable whether or not it appears above.

The route is the same either way: start a recovery. The report tells us exactly what your machine is, and the reply is a firm yes or no with a firm price. Nothing is owed if the answer is no.

Start recovery
