Hi there! i need your help regarding BIOS password not working on my emachine(also known as e-system) ei3103 notebook laptop, the issue is not that i have forgotton my password, i am applying correct password but its not accepting it, when i give it 3 times, then i get 'System Disabled' message with some error code.Perhaps i could fix it if i have not applied the same password not only for entering in BIOS, but i also applied it on system start up, so can not even boot it from the CD as first boot device option setting (as i did not set it earlier),i have found CMOS clear guide on internet by removing internal battery Cell(even for more than 20 minutes) but it did not solve my problem, i can not even boot it from CD to use any CMOS clear software from it, as the first boot device was harddisk.Then i used a guide to remove RAM and short circuit two points under it to clear CMOS but it did not work as well, guide here:

As suggested, a cold power reset and removing the CMOS cell are reasonable first steps, but since already saw the "checksum error / default set" message and the boot password still appears, the situation strongly suggests the power‑on password is kept outside the little RTC coin cell (in non‑volatile flash or a separate security/EEPROM) and therefore will not be cleared by battery removal or simple jumper tricks. (h30434.www3.hp.com)

Practical next steps (ordered, low-risk to higher-risk):

  • Look closely for any numeric/alphanumeric code displayed with the "System Disabled" text and record it. Some vendors expose a challenge code there; community tools/sites have been used to generate possible master/unlock passwords from that code (success varies by BIOS vendor). Try any returned candidates, power‑cycle between attempts, and try every candidate the generator supplies. (superuser.com)

  • Remove the internal hard drive and try to boot from CD/USB. If the machine still stops for a power‑on password before any boot device is tried, that confirms a firmware/BIOS lock (not a drive password) and makes DIY fixes less likely.

  • Contact Acer (eMachines is handled via Acer legacy support) or a local authorized service center — manufacturers will typically handle BIOS unlocks only after proof of ownership. This is the normal, supported path for older branded laptops. ()

If professional service is not an option and there is comfort with electronics, the final technical option is to dump and reprogram the SPI/EEPROM that holds the firmware (SOIC clip + CH341A or equivalent, then patch/replace the image). That route is advanced, can brick the board, and may not work on systems that store security in fused/hidden regions — it is best left to experienced repair shops. (github-wiki-see.page)

Cautions: preserve proof of ownership, expect possible service charges, and avoid repeated blind attempts that can lengthen vendor support steps or risk permanent lock.

When something like this happens, the first thing you do is a full system reset - usually by shutting down the system cold, removing the battery (and no wall-plug connection), and then holding the power button down for some period of time (10 seconds to 1 minute). If after reinstallation of the battery and rebooting the system you still can't get in, then you need to do a full cmos/flash wipe. In that case, you will have to pull the keyboard to get to the motherboard, and (again with system shut down and battery removed) short out a couple of pins for a few seconds. Which pins depend upon the motherboard and you will probably need to get that information from the e-machines support web site. They may have better advice on how to do that for you.

hi rubberman ! thanks for the help, yes you are right, but i have tried all ways i know, which is online and which you have told here, but nothing works, its strange !even there is message something like 'checksum error, default set' which is said that its about the cmos flashed success message which means that your cmos is flashed and cleared, i got this message many time, but when i let it go ahead, there is same password input message, which don't accept anything, now it seems for me that i will have to consult its Service Guys or take it there, but i have come to know its strange stupid thing, which should not happen in motherboards.
