I recently picked up some second hand laptops as projects for spare time and to learn a bit more. One of these is a Lenovo 3000 N100. I'm not sure of the exact model as the COA sticker is worn away. The laptop came without RAM, Hard drive, or battery! I'm aware this may be more effort than its worth, but wanted to give it a go.....
With RAM installed, the white Lenovo splash screen displays (sometimes quickly, sometimes takes ages) - if i press Esc then the following info is displayed:
Unknown Project ID!!! BIOS Version ??? 61ET32WW
CPU = Intel (R) Celeron (R) M CPU 410 @ 1.46GHz
1023M System RAM Passed
1024K Cache SRAM Passes
System BIOS Shadowed
Video BIOS shadowed
Pressing F1 or F12 does not do anything.
The following errors are then displayed, which from Google I can see is a common problem. However, I cant find a fix that applies to me.
PXE-E61: Media test failure, check cable
PXE:MOF:exiting PXE ROM
Operating System not found.
From what I can see online, the laptop is trying to boot from a network/LAN. I tried an XP boot CD with no joy.
I can't access BIOS to change boot priorities.
The RAM appears to be functioning judging by the above messages?
I tried putting in a blank HDD and removing it (tested HDD using novatech USB SATA adapter, appears to be working fine).
Is my next option to reset the CMOS battery? I should add that on the first screen I initially received error codes 0271 and 0251 regarding system date and time and CMOS checksum bad, but having left the laptop plugged in overnight, these are no longer appearing.
Solved! Go to Solution.

Welcome to the Lenovo Community !
I'm not an owner of your model, but in reviewing the Hardware Maintenance Manual for the N100 it notes that you must press the Lenovo Care Button when the computer is powered up. You will then be presented with a menu from which you can access the BIOS Setup. Page #104 of the manual will show you the location of the Care Button. Here is a link to that manual for your reference......
As for clearing the CMOS, it is probably not needed. If the time and date were cleared and you received a CMOS checksum error then all the information stored in the CMOS was likely cleared when the battery lost power from sitting unused.
Once you are able to get into the BIOS you should be able to correct the boot order so that you can use the XP boot disc.

Thanks for your response. Sorry, I forgot to mention that I tried accessing the BIOS via this method - I can get the desired menu up using the Lenovo care button, but when I press F1 (the menu option to access the BIOS) nothing happens, the laptop simply proceeds to the PXE Error once the timer runs down. The other options give the same result.

I would pull the LAN / wireless card to see if that made a difference in accessing the BIOS. After the card is removed and before trying to boot the computer up, do this......
1. Unplug the charger / adapter.
2. Remove the battery.
3. Press and hold the Power Button for 15 seconds.
4. Re-install the battery, plug in the charger / adapter if needed and power up the system to see if the problem was resolved.

The problem you are encountering maybe why the laptop was retired in the first place. I would give it one more try and remove all the hardware like the hard drive, optical drive and memory to see if it will boot differently then it has been. If so, add back the memory and see how it boots. If you still can't access the BIOS Setup then I would suspect a motherboard problem.

Sorry for the delayed response - I still havent been able to access the BIOS, however - think I had an issue with my XP CD as I have been able to install windows using another CD and Ultimate Boot CD also loaded. I'm now going to try to update drivers (and hopefully BIOS) and hoping that will solve the issue. Thanks for your help!

No apologies needed for the delay.
I can't understand why you still can't access the BIOS, but it sounds like you have made progress with the OS install. Hopefully a BIOS update will resolve the remaining issue.
You're more than welcome. Thanks for the update.

No wonder the BIOS issue was confusing - it turns out that F1 and F12 are dead keys, along with one of the Ctrl keys (I used an online keyboard checker to test). So the key for BIOS access and for the boot list both were not working. I managed to access BIOS using a USB keyboard. I think i'll try to reseat the keyboard first, if that doesn't work, have a go at an individual key, and if that fails - a second hand keyboard. BIOS is not the latest version, but I guess there's not a massive need to update?
XP installed for now, as I don't have any spare Windows 7 keys. I have some 2Gb RAM modules, so will upgrade it to the maximum 3Gb. Then decide whether to keep it or not! I've a Z60M which I prefer, so this one will probably get given away or sold. Just a shame the RAM is so limited on them.

Good detective work with the keyboard.
As for updating the BIOS, if you have narrowed the problem down to a defect in the keyboard then I would avoid the BIOS Update. When the keyboard is fully functional then is the time to update if it is still needed.
