Bios Password help

I have an Acer Aspire 3100 configured by Sultex PC in Kentucky now out of business, I cannot boot from any external device and cannot enter the bios setup to enable that function. It has a Phoenix Trusted Core NB Bios version 1.90. I've tried the backdoor passwords to no avail. Does this laptop have a cmos clear jumper on it or a removable battery or is there a way to identify the Motherboard?

The cmos battery is soldered on mainboard if you know what are you doing and can disassemble the laptop just short the battery terminals for 1-2 seconds and that should clear all settings here is a photo http://mainboard.en.alibaba.com/product/624925883-213834902/laptop_motherboard_for_ACER_ASPIRE_3100_series_LA_3121P_AMD_NON_INTEGRATED_ATI_Radeon_Xpress_1100_DDR2.html

SOURCE: Gateway MX6030 bios/boot password reset

How long did you leave the battery out?
To discharge the BIOS you need to short out the battery contacts, or disconnect the battery for 1/2+ hours.
If this does not work the it is near impossible to remove because the password would be stored on an EEPROM chip.
Check with Gateway, they might suggest a motherboard replacement just like IBM.

SOURCE: Can anyone help me on how to reset the Bios

A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

0280:Previous boot incomplete - Default configuration used


Error Code: 0280 Previous boot incomplete - Default configuration used


Message Meanings : Previous POST did not complete successfully. POST loads default values and offers to run Setup. If the failure was caused by incorrect values and they are not corrected, the next boot will likely fail. On system with control of wait states, improper Setup settings can also terminate POST and cause this error on the next boot. Run Setup and verify that wait-state configuration is correct. This error is cleared the next time the system is booted.

What does the above mean ??? If the BIOS does not see a particular device loading ( like Hard Drive ) Try bringing up the Bios setting F-2 and reset to default. Hope this helps

No bootable device insert boot disk and press any key acer aspire 5741g. Then I turn on my acer aspire 5741g . This is my problem. Can you help me ?


The notebook cannot detect the hard disk when you turn on the notebook.
First - re-seat the harddisk and reboot the computer. If the computer does not boot up then reboot andgo into the BIOS configuration to see if the BIOS detects the hard drive. If itdoesn't detect the hard drive then it could be faulty. Next - to check if the harddrive is faulty, remove the hard drive and insert it into an USB hard drive adapter and connect it to a workingcomputer's USB port. If this computer cannot see itas an external hard drive and you cannot open the various folders and files,this confirms the hard drive is faulty. Then the hard drive needsto be replaced in the computer/laptop, Windows installed and the computer orlaptop's device drivers plus your programs etc. to get a functioningcomputer/laptop again.

Acer Aspire One has Hard drive Password frozen


There should not be a password set in the BIOS unless you set it up with one. You can clear the BIOS to BRAND NEW state. Acer can guide you through this if it is under warranty. If it is not, write back and I will help you do this.

Acer aspire one - its died!!!


If it was just the hard drive, I would expect the video to come on and say something like "no boot device."
However, since you went through the steps here and see absolutely no video (even none on an external monitor), I would suspect a motherboard failure.
Be sure that when you hooked up an external monitor that you pushed the Fn key and the appropriate special function key (maybe F7) that switches between the laptop and external monitor. If you have done that (pushed the combination several times to switch displays), then you can be pretty certain your video card (if a separate card) may be bad.
I'm not really sure if this machine has a separate video card. The specs say it's a ATI Radeon Xpress 1100. This leads me to believe it may be a separate card.
If it's just the card that went bad, you can replace it. Otherwise, the motherboard will have to be replaced.
Good luck. You can do that, but if you're not confident, you best take the machine to a repair shop.

If you where the CMOS battery is, there's beside it a jumper inserted in two of the 3 pins(left pin and middle pin). Remove the jumper from its original position and with it short the middle pin and right pin. This resets the CMOS ROM to its default settings minus the password. Return the jumper to its original position as before. Reboot the computer.
