This might come in handy one day! I just hope I won't forget about it!

Compaq?:eek:
haven't a compaq computer for at least 10 years.

Great post! Now do one on BIOS backdoor passwords :wgrin:

A small addition: in Compaq machines old enough to be irrelevant today, F12 will let you access either the BIOS or the boot menu depending on the model.

I already have it, and much more :) I will do it sometime this week.
For those that are worndering why I wrote these in this weird layout is because that's how I write notes in my text files. 3 line space similar items, 4 lines space for different areas.

Yes but these notes apply to all machines, not just current ones.

Hm... how do you update bios?

Depends on the motherboard. Newer motherboards 2010-present have in the BIOS an option to update it using a .bin rom file copied to a USB stick or HDD.
If you do not have that option in your BIOS, you will need to get a Windows 98SE startup disk and execute it from there.

Nice job! This can come very handy!

If your motherboard is from this decade, chances are the BIOS update can be flashed from Windows and without rebooting.

UEFI?

Then hold SHIFT + Click restart
Hold SHIFT until you see menu

ALSO WORKS WITH TPM AND SECURE BOOT

:)

You can reinstall windows10/11 there without deleting files or make a clean installation
but all programs will be gone

Cheers

And I also found that if you press SPACE during POST it will pause the screen. Very useful to read when the timeout is set too short.

Ugh. Last time I repaired a Vaio, I had to spend an hour learning this through trial and error :pinch:

This is from my laptop's BIOS update guide.

BIOS Recovery

Copy MPxxxxp.cap to root directory (not in any folder) of the USB flash drive and rename to BIOS.cap
On the Marble Point keyboard (a USB keyboard can NOT be used) press: the function key and the R key at the same time. Fn+R
Plug in AC and the LED will blink.
Press power button.
The BIOS will update and the computer will shut off.

It would be nice to collect hidden tricks like these too, but there must be dozens, and most of them model-specific.

Most of these come from my own experience, but I also got them from someone that had them written in pencil on sheets of paper. They got so old it's difficult to read.

Thanx alot for this, i have Lenova laptop that i bought from someone long time agio and the bios was lcoked, i still can enter bios but cant make changes, some people could help but i have to send my laptop to them so they do something with hardware? is that true?

anon, could you replace my original posting with the content of my post with number 10? I fear some may miss it.

I'm afraid so. A hardware reflash is required to remove these locks if you don't have the actual password, which is why I adviced to beware of stolen goods in the other thread. Do not buy a used laptop if the seller won't provide evidence that the BIOS and/or hard drive are not password-protected.

Done.

I found this guide in youtube and i wonder if you guys think its good or bad? im planing to make this at home, https://www.youtube.com/watch?v=aXbW4uGy3EM

my laptop is: Lenova T470s
Edit: i tried to mention anon and Master Razor but it didnt work ;)

As someone with experience using a CH341a programmer, I can confirm that method works. However, there are several caveats the video does not address.

MAKE A BACKUP OF THE FULL ROM CONTENTS AND TRIPLE-CHECK IT BEFORE DOING ANYTHING. You can't just flash a BIOS update from Lenovo if something goes wrong because those are not full ROMs, and if they somehow were, they wouldn't contain data that is unique to your system like MAC addresses, UUIDs and the licensing table.
The flash chip may not be so easy to reach. Near-complete disassembly may be required, with all the screw and part order tracking that implies. Download your laptop's service manual and keep it handy before you need it.
Handle the chip with extreme care. If one of the pins breaks, you'll need to buy an identical replacement, and if this happens before following point no. 1, you're fucked.
The voltage rating for the IC and your serial programmer must be the same. Using a 1.7V programmer on a 3.3V chip won't work. Doing it the other way around has a chance of frying the chip. You may be able to work around a voltage mismatch by blocking the pin the IC gets power from (usually #8), but don't rely on that.
Triple check the ROM contents after flashing too. Sometimes successful flashes actually aren't; sometimes successful verifications actually aren't.
If you don't have the right equipment or aren't confident in your soldering skills, you can use a clamp instead, as long as you disconnect each and every thing from the board where the chip is located (you don't want electricity from the programmer flowing to the rest of the laptop). The pin-blocking trick mentioned above may also be necessary even if the voltages match.

It may sound like a lot to take in, but don't be intimidated. Just follow the steps carefully and you'll be fine!

So, any luck with the unlocking?

If you're thinking there's no point in spending money on a serial programmer you'll only use "this once", I felt the same way at first, but the ability to flash anything with a compatible IC was worth it. Same goes for my USB-TTL adapter... especially considering you'll get charged around the same or more if you pay someone else to do this.

i relly like to try it, not problem with welding but considering what the bios upgrade will give me once i update , its not worth the cost of buying the tools but im happy its now posible to do it

I don't understand, what will the BIOS upgrade do?

Wow, sweet cheat sheet!

Very helpful, thanks for the list
