Just one question: You wrote "3 In case of laptop:...".

you have my long answer, , the maker will never answer this,. (why not ask them?)
it voids warranty this, so PC specs are near ZERO. (ignorance is bliss to them and most other OEMs)

N3350 SOC it is. "system on a chip"
learn to read all chip top logos, and the one from top EEPROM make is BINGO. learn it , it is each here
is a list.

and winbond. too. FLASH EEPROM it is.
there are more, (history is DEEP)
i used to work for NXP so , know a few tricks(grin), Phillips sold to China. NXP, (means I guess next Phillips) cute.
most are 8 pin chips, find them all write down all logo shapes to paper and part numbers
google that P/N and learn what chip it is.

common is SPI forum factor pin out (Serial)

see packages used here, many kinds but less now.

see how DFM packages will stop you , bottom balled.


here is one common chip used in CHINA, "ON" SEMI

UDFN will be a hard nut to crack (the solder pads are under the package not on sides) means hidden.
some FLASH are encrypted now and or a PW locked out. (vast EEPROMs exist and feature sets)

case in point this chip here, above link
Hardware Write Protection for Entire Memory <<< read that yet? no job told but I bet it is not just reading, it.

Hi,

The IBM Thinkpad has a very strong security system.

If you are seeing a lock symbol when booting then somebody has set the supervisor password. If you can't remember it or guess it (try "password", "admin", "pass", etc) then you need to find the person that set the supervisor password.

Once the supervisor password is set the T41 is very well protected and it can't be reset by removing the laptop battery or CMOS battery.

There is a way to read the password from the protection chip but this is very complicated and requires taking the laptop apart and building your own chip reader.

The instructions for doing this are are:

Hope this helps,

you have to clear the cmos.Take the bios battery out.

OK, I posted this the other day, so for the benefit of those who missed it. "None" of these techniques will work on the R52, as it has a different chip. The above well intentioned solutions mentioned above will work with older models but not this machine as the bios chip has been changed. FYI

find the bios battery and remove it for al least an hour, make sure the laptop battery is removed and AC power is unplugged

Taking out the battery does not work anymore. The bios password is now held in an electric erasable read only memory chip AKA (EEPROM). Its a little labor intensive process to erase this chip and I am not going to go into it here. But if you rate this fixya and post an E-mail address where I can send you contact info I will send you the info you are seeking and teach you.

probably a little bit late but I think I found a solution ...

1.pull the hard drive out of the laptop
2.boot computer into bios settings
3. set a new bios password and check lock computer
4.while the computer is on slide the HDD in the laptop again.
5. save and exit bios
6.fortunately in the next boot you will get your hdd back

You mean a BIOS password? or a password on your Windows account.

In case of BIOS password: you need to reset the CMOS (Chip that holds data for BIOS). You can do this by removing the CMOS battery or use a reset switch/jumper on your motherboard. If this is the case tell me and I'll walk you through it.

In case of Windows: Boot until logon screen. If it's the blue welcome screen press Ctrl + Alt + Del 3 times until a small login box appears. Type the following:

Username: Administrator
Password: the password set at install, or is most case: leave blank.

Once logged in, go to Control Panel > User Accounts. Select your user and change the password.

I hope this helps solving your problem.

The V-chip has a 4 digit numerical password in order to keep older children from changing its settings. However, it can be overridden by savvier youth who read the television's manual to find out how to reset the password to 0000 (built into the V-chip in case the parents themselves forget the password that they set).
