I need to change the boot order on an old Acer Aspire 4410/4810T laptop that I have, but as soon as I hit F2 on startup it asks me for a BIOS password. I have no clue as to what the password is.
I have read a number of web pages that offer weird and wonderful ideas1 for resetting the password, but the three main options seem to be:
This tips are covered in this video, How to Clear/Remove Acer Bios Password, and appear to be backed up by numerous other sites.
As I have said, option one won't work for me - as I can not change the boot order, due to the required password (chicken and egg).
I have located the RTC battery (I am not sure if that is the same as the CMOS battery), using this complete disassembly guide, Aspire 4810 SeriesDisassembly Instruction, which was linked to from How to disassemble Acer Aspire 4810T 4810TZ 4410. The complete disassembly guide does not show the CMOS battery, but does show the Real Time Clock (RTC) battery. I disconnected this, for an hour, but still I was asked for the BIOS password, when hitting F2.
So, I am still looking for the BIOS/Password reset jumpers. I have seen photos of many acer laptop motherboards showing the jumpers and their location, just not for the 4810T.
1 This site, How to Reset an Acer BIOS Password, makes mention of the Acer proprietary software Acer eSettings Management, that has a pre-requisite of Acer Empowering Technology. I read a comment on this site, Windows 7: Acer eSettings Management is not on my acer laptop, which says that eSettings Management is now called the Launch Manager, from the Acer downloads page - a dubious claim. I have installed the Launch Manager, regardless, but I was not able to find the software after the reboot.
This page, ACER eSettings Management Software? was useful, but says that eSettings Management only works on Vista. Plus, this page, Acer Empowering Technology question, implies that it is bloat ware.

If you can still load the operating system, you can reset the password with Acer eSettings Management (Acer eSettings Management --> Click BIOS Passwords near the footer of the screen --> Use Create Password or Remove Password option).
As for hardware reset, the reset jumper should be marked CLRP1. If you cannot find that one, just remove the battery, wait up to 1h and re-attach it.In the service manual page 57, they show where the battery is located and how to remove it.

The answer, from page 97 of the service manual is, in fact:
Steps for Clearing BIOS Password Check
If the user sets the BIOS Password (Supervisor Password and/or User Password) for a security reason, the BIOS will ask for the password during system POST or when the system enters into the BIOS Setup menu. If it is necessary to bypass the password check, the user needs to short the hardware gap to clear the password by following these steps:
NOTE: The steps are only for clearing the BIOS password (Supervisor Password and User Password).
And the location of the jumpers, which are described as HW Open Gap position on M/B space, or G61, are here:
I would never have found this, had it not been for Overmind's answer.

Reviews for the Acer Aspire 3810TZ
Acer's Aspire 3810TZ, this superbly-balanced inexpensive ultraportable wins our roundup
Source: PC Authority The worst aspect of the Aspire 3810TZ is its speakers, which sound tinny and lacklustre by comparison with the best on test. Other than this small gripe, we can't find fault - this Acer is the very definition of a superbly-balanced, inexpensive ultraportable. Some may crave more power than it, or any of its ilk, can muster, but for many the balance of power, portability and sheer tactile excellence will prove more than ample reward.

It's quite thin and lightweight, partially due to the exclusion of a DVD drive. It's got decent build quality, along with a comfortable keyboard and touch-pad.
