A Toughbook FZ-G1 BIOS password will not clear when you pull the battery or reinstall Windows, but the original password can usually be recovered from the tablet’s own firmware, provided the tablet still boots into Windows. You save a copy of the BIOS ROM with a small AMI utility and send me the file. I read the password out of it. Nothing gets flashed, and the tablet stays on your bench the whole time.
What the FZ-G1 is, and why so many turn up locked
The FZ-G1 is Panasonic’s 10.1-inch fully rugged Windows tablet. It launched in 2013 and ran through five marks, Mk1 to Mk5, before the FZ-G2 replaced it in 2021. Over that run the processor moved from a 3rd-generation Intel Core i5 to a 7th-generation one. The shell barely changed, so check the label on the back to see which mark you have.
These tablets went to utilities, field service crews, warehouses, police and EMS, often living in a vehicle dock. Fleet IT departments set a supervisor password on every unit as routine. As a result, a lock usually just means the tablet left the fleet and the password did not.
There is also a reason so many are for sale right now. Windows 10 support ended in October 2025, and no FZ-G1 processor is on Microsoft’s supported list for Windows 11. Because of that, fleets are retiring G1s in bulk. They reach surplus sales with a wiped drive and a Setup screen nobody can open.
Where the Toughbook FZ-G1 BIOS password is kept
The G1’s battery unlatches from the back in seconds, so removing it is the first thing most people try. The Toughbook FZ-G1 BIOS password sits in a flash chip on the motherboard, alongside the AMI firmware itself. That chip holds its contents with no power at all. Therefore none of the following will clear it:
- Leaving the battery out. An hour or a month makes no difference.
- Swapping the SSD. A different drive gives you a different Windows. The firmware never notices.
- Reset this PC, or a clean install. Both rewrite the drive and stop there.
- Looking for a jumper. The board has no clear-password jumper, and opening a sealed rugged tablet puts its gaskets at risk for nothing.
So a true “reset” is off the table. What works is recovery: learn the original password, then change or remove it yourself in Setup.
Two snags that come with a tablet
Reaching Setup without a keyboard
The G1 has no F2 key. To open Setup, touch the top-left corner of the screen while the Panasonic logo shows, or plug in a USB keyboard and press F2. If a supervisor password is set, the prompt appears at that point. Keep that keyboard handy, because typing a recovered password is far easier on real keys.
A Setup lock versus a power-on lock
Most locked G1s start Windows normally and only ask for a password when you try to enter Setup. That is the good case. Admittedly, you cannot change the boot order to start a USB installer, and you cannot switch back on a camera, GPS, barcode reader or cellular modem that the last owner disabled. However, the tablet runs, and that is enough to extract the ROM.
The bad case is a password prompt at power-on that you cannot get past. Windows never loads, the extraction tool needs Windows, and so the software route cannot be done.
Which Windows your G1 runs, and which tool to use
Eight years of production means the FZ-G1 shipped with more Windows versions than most Toughbooks:
- Mk1 to Mk3 (2013 to 2015): Windows 8 or 8.1 Pro, or the Windows 7 Professional downgrade that many fleets chose and never left.
- Mk4 and Mk5: Windows 10 Pro, with a Windows 7 downgrade still offered on the Mk4.
Many early units were upgraded to Windows 10 later, so do not guess from the mark. Open Settings > System > About, or run winver, and note the System type line as well. A 32-bit Windows 7 install needs the 32-bit tool.
On Windows 10 or 8.1, try the AMI-Windows-11 folder first and step down to AMI-Windows-10 if it refuses to save. On Windows 7, go straight to AMI-Windows-7. One G1 wrinkle: the early marks carry older AMI firmware than the later ones. An early tablet may only save with the Windows 7 tool, even when it runs Windows 10. The tool only reads, so a failed attempt is harmless. The ROM extraction guide shows every click.
Two touch-screen tips. “Right-click” on a tablet means press and hold, although a USB mouse is simpler. The tablet has a single full-size USB port, so a small hub or the desktop cradle helps.
How the recovery works
- Message me with the model (FZ-G1, plus the mark if you know it) and your Windows version. I reply with a link to the tools folder.
- Sign in to Windows as an administrator, with the tablet on AC power.
- Press and hold on AFUWIN, choose Run as administrator, then tap Save. Never tap Flash.
- Rename the file after yourself, for example
John_Smith.rom, and send it. - I review the ROM before you pay anything. You only buy if I confirm the password is recoverable.
- I recover the original password from your file and mail you a printed Recovery Report.
Meanwhile, do not run a BIOS update while your file is under review, because the review is of that exact image. For the full sequence, see How It Works. The Toughbook BIOS password recovery service page covers the rest.
Message me before you buy
Please contact me first and purchase second. Message me through eBay before you buy, or use the contact page. Say you have a Toughbook FZ-G1 BIOS password to recover, and tell me which Windows the tablet runs. Then send the ROM named after yourself. I look at the ROM first, and you pay only once I confirm recovery is possible.
The CF-19 convertible has its own page, and so do the FZ-G2 that replaced this tablet and the 7-inch FZ-M1. The supported Toughbook models list covers the rest. The pricing and what you get page describes what comes with the report.
Owner-authorized systems only. I work on Toughbooks you own or are authorized in writing to service. A tablet that still belongs to an agency or a company needs that authorization from them. I may ask for proof of ownership.
