How do I reset bios on acer travelmate 250


To enter the BIOS Setup Utility, you just need to press F2 during POST (when your device is starting up). From the Setup Utility, you can reset all parameters to default.

However, if the problem is that the Setup Utility is password-protected and you don't remember the password (we've all been there), then there's a moderately complex procedure for manually resetting the BIOS and CMOS, but it will require removal of the keyboard to access a dipswitch bank underneath. To do that, you will first want the Service Manual for the device, which you can find here:
http://tim.id.au/laptops/acer/travelmate%20240%20250.pdf

You'll want that manual anyway... details on the BIOS and configurable options are in Chapter 2 (which starts on page 34).

If you need to reset the BIOS/CMOS to remove a password, first you'll need to remove the keyboard (see page 63, although it will refer you to also see pages 52 and 56). After removing the keyboard (PLEASE be sure to keep track of all your screws and parts, and also be sure to wear an anti-static wristband), you will be able to access a dipswitch bank on the motherboard that will be marked "SW1". For location of this, refer to the diagram on page 108 - the bank is marked "3" on the diagram,

The dipswitch bank will have 4 switches. For the purpose of resetting the password, you only need to concern yourself with the first switch on the left hand side. It will most likely be in the "on" position (1); switch it off (0). Reassemble your device ONLY to the extent necessary to restart it - in other words, hook the keyboard back up, put the battery back in... but don't reinstall the center cover or put any screws back in the case, because you're going to have to get back to the dipswitch.

Now, restart your computer. Wait for it to boot the OS, then properly shut it down. Unplug it, take the battery out and remove the keyboard again, and move the dipswitch back to the "on" position. Reassemble your device, check to make sure there are no spare parts, and restart, pushing F2 at POST to get to your BIOS Setup Utility. Your password should now be cleared and you should be good to go.

Hopefully this helps... Having disassembled many laptops myself over the years, I'll say a couple of things: First, it's not as scary as it seems. Second, make sure you have that anti-static wrist strap. They only cost $5 to $15, and it can save you hundreds if not thousands in electronics replacement cost. Third, TAKE YOUR TIME. Don't rush anything... make sure you keep track of the screws and where they go (the diagrams in the service manual will be of great help... I recommend printing out the relevant sections so you have easy access, and also keep the manual for future reference... store it in the cloud somewhere so you can access it from another device). Servicing your own electronics can save a lot of money and at the same time enhance your knowledge of the devices you use every day as long as you practice patience and approach everything in a methodical way.

Have fun, and good luck!

Bios password problem on a hannstar j mv4 94v


you will need to get to the jumpers for bios to be able to reset the password or remove the password, this is easy with a desktop computer, but if you have a laptop but you think you guys can open the laptop and locate the bios or cmos jumpers then go ahead.
>
On the computer motherboard locate the BIOS clear / password jumper or dipswitch and change its position. Once this jumper has been changed, turn on the computer and the password should be cleared. Once cleared, turn the computer off and return the jumper or dipswitch to its original position.

=======================================
The location of the jumpers or dipswitches may vary; however, here are general locations where these jumpers / dipswitch may be located.
  1. On the edge of the motherboard - Most jumpers are located on the side of the motherboard for easy accessibility, verify by looking at all visible edges of the motherboard.
  2. By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual CMOS battery.
  3. By the processor - Some manufactures will place the jumpers by the processor of the computer. However, note that in some cases these jumpers will be to change the processor and not the password.
  4. Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.
  5. Other visible location - While it is possible that the jumpers / dipswitches may not be in a visible location, most manufactures try to make things easier by placing the jumpers / dipswitches in another visible location.

Forgot BIOS password


Question: How to clear an unknown BIOS password.
Answer: If you have mistakenly forgot or lost your BIOS password or you receive a password at boot that you do not know, you will need to clear the BIOS password by one of the below methods.
Precaution: When inside the computer please be sure of the potential of ESD.
  • Try using generic BIOS passwords. A complete listing of these passwords can be found on document CH000451.
  • There are utilities designed to help bypass BIOS passwords. An example of a great utility to decrypt / bypass BIOS passwords is the PC BIOS Security and Maintenance toolkit, which is available by clicking here.
  • On the computer motherboard locate the BIOS clear / password jumper or dipswitch and change its position. Once this jumper has been changed, turn on the computer and the password should be cleared. Once cleared, turn the computer off and return the jumper or dipswitch to its original position.
The location of the jumpers or dipswitches may vary; however, here are general locations where these jumpers / dipswitch may be located.
  1. On the edge of the motherboard - Most jumpers are located on the side of the motherboard for easy accessibility, verify by looking at all visible edges of the motherboard.
  2. By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual CMOS battery.
  3. By the processor - Some manufactures will place the jumpers by the processor of the computer. However, note that in some cases these jumpers will be to change the processor and not the password.
  4. Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.
  5. Other visible location - While it is possible that the jumpers / dipswitches may not be in a visible location, most manufactures try to make things easier by placing the jumpers / dipswitches in another visible location.
Additionally, when looking for the jumper / dipswitch the label of that switch can be anything; however, in most cases will be labeled CLEAR - CLEAR CMOS - JCMOS1 - CLR - CLRPWD - PASSWD - PASSWORD - PWD.
  • On the computer motherboard locate and remove the CMOS battery for at least 10 minutes allowing the computer to lose its information. Note: this will not work on all computers.
  • If your manufacturer has a bypass password this can be entered and allow you access to the BIOS and/or computer. Because of the security risk of a bypass password, generally only older computers will have this option. In addition, it is likely that this information will only be able to be obtained from the computer, motherboard or BIOS manufacturer.
  • On the computer motherboard locate the CMOS solder beads and jump the solder beads to clear the password. The identification and location of these solder beads can vary and if not available in computer documentation is generally only obtainable through the computer manufacturer.
If one of the above solutions do not clear the password or you are unable to locate the jumpers or solder beads, it is recommended you contact the computer manufacturer or motherboard manufacturer for the steps on clearing the computer password.
