Do you know how to access your computer's BIOS settings? It sounds to me like an advanced setting called "Hard Disk Boot Sequence" (or just "Book Sequence") may be mis-set. Normally,the setting would be HD first, then CD, then etc-etc-etc down to usually last of all, Floppy Drive. It sounds very much to me like yours is set to boot the floppy drive ahead of the HD.

When your computer is starting up, watch carefully for writing on the screen (usually top-left or along the bottom) that says "Enter Setup" - and press the key it says. I don't have my Thinkpad any more, and there were numerous contributors when I searched this for you, but most said "Hold down F1" while powering on and keep it down until a long beep" - Others said that if you can get to a DOS prompt do so and press CTRL-ALT-F11.

THE MAIN THING HERE IS THIS: BE CAREFUL IN SETUP. This is one place where you can cause yourself a lot of grief.. If you don't find the boot sequence screen (or if you do, and it's OK) write back with more information. BEST OF LUCK! We're here to help.

Most computers have a 'keep-alive' coin-cell battery on the motherboard that provides a DC voltage to keep the bios memory contents preserved when the computer is turned off. After a couple of years, the batteries need to be replaced with new ones. Look online for the service manual for your Thinkpad or look up 'Thinkpad 380ED bios battery replacement' on your favorite search engine to see if you want to tackle the process yourself.

Hi there,
You need to make sure your laptop meet the minimum hardware requirements for windows XP . (see below)
I believe your system has a Pentium MMX 166 MHZ processor which will not be able to run XP properly.
But that's not all, You also need to make sure IBM Lenovo provides drivers for all the hardware on your 380ED, which I don't believe it does.

Minimum hardware requirements

  • Pentium 233-megahertz (MHz) processor or faster (300 MHz is recommended)
  • At least 64 megabytes (MB) of RAM (128 MB is recommended)
  • At least 1.5 gigabytes (GB) of available space on the hard disk
  • CD-ROM or DVD-ROM drive
  • Keyboard and a Microsoft Mouse or some other compatible pointing device
  • Video adapter and monitor with Super VGA (800 x 600) or higher resolution
  • Sound card
  • Speakers or headphones

Hi, If you are talking about the Boot, HDD, Bios password, then the only one way to recover it is to implement a chip on the systemboard to shorcut the protection or to contact Lenovo for a systemboard replacement. Otherwise you can check out theses 2 tutorials, with few skill you can make it yourself: -http://www.allservice.ro/forum/viewtopic.php?t=47&start=0 -http://marc.info/?l=full-disclosure&m=111234041830357&w=2 Unfortunalty, no other ways other round. Thanks and have a nice day J-

The word please goes a LONG way with me. Makes me want to 'break my neck' to help that person;

991009, this is Lenovo Support > ThinkPad 380ED 2635 Notebook PC >
Manuals download page,

[ Note:

Manufacturer name: IBM
Model (Line): ThinkPad
Model Series: 380
Subseries: ED
Machine Type: 2635 ]


HMM stands for Hardware Maintenance Manual. It is a Service Manual.

Under the bold heading - User Guides and Manuals - click on -
Hardware maintenance manuals

In the drop down list, you want the first file listed.

Under the subheading -
Hardware maintenance manual Volume 4 ( September 1997) - ThinkPad 380, 385, 560/E, 760, 765,

click on the blue - [ + ] Click for files

Under the - Name - heading, click on the blue -

ThinkPad 380, 385, 560, 560E, all 760, 765, and SELECTADOCK III
Hardware Maintenance Manual (March 1999)

The service manual (HMM) is a PDF file.

[ Disregard the following if you are aware;

The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the above file name it may take up to 30 seconds, before the first page comes up.

[Took 10 seconds just now, with medium speed DSL connection ]

At the top of the PDF file in the header is the Zoom In icon, ( + ), and Zoom Out icon, ( - )

Zoom In increases the view size.
Zoom Out decreases the view size.

You can decrease to see the entire page, or increase, (And use the side/bottom bars), to view a particular subject on the page, Up Close.

To the Right of the Down Arrow is the page number box.
You can use the Down Arrow, (And later Up Arrow), to arrive at the page you want,


If you know the page you want you can do this;

1) Put your mouse cursor in the page number box. Left-click once,
(Anything in the page number box will now be highlighted in Blue ),

2) Type the page number,

3) Press the Enter key.

Page numbers in the PDF page number box, do NOT match the actual service manual page numbers.

Page numbers I refer to will be in the PDF page number box.
You can also click on the Bookmarks menu icon to the left, to arrive at the section you want.
[ It is right above the paperclip icon ]

You can save a copy to your computer. This way you can burn a copy to disk, or flashdrive, for safekeeping.

Then after checking out the copy is indeed good, you can delete it from the computer, and save harddrive space.
If you do not know how to do this procedure, and wish to, just state in a Comment ]

Go to Page 72.

[ Bookmarks menu;
1) Click on the + sign next to - ThinkPad 380, 385 (2635)

2) Click on the + sign next to - FRU Removals and Replacements

(FRU = Field Replaceable Units.
In otherwords for the tech in the field. If the tech cannot repair on site, the unit is sent to the manufacturer for repair, or replacement ]

3) Click right on - 1020 DIMM Card / Backup Battery

From me;
A) Remove ALL power. Remove the AC adapter (Charger) if plugged in, and remove the Battery.

B) Suggest lay a soft static free cloth on the table you're working on.
(NEVER work on a bed, couch, or directly on a carpet floor!
HIGH areas of Static electricity )

Turn the laptop over, bottom side up, Battery Compartment to the lower right. (Towards you)
Lay on the cloth.

Right above the Battery Compartment is the DIMM Card / Backup Battery Compartment.

Loosen it's single screw all the way. (It shouldn't remove )
Lift the cover up on the same side as the screw. There are plastic tabs on the opposite side.

The Backup Battery is to the left of the Ram Memory module/s.

(Note* The Positive { + } symbol on the battery ALWAYS goes UP, when being installed )

For additional questions please post in a Comment.

Replace Bios battery under screwed down panel under laptop. You get a dtae error, reset date and time then your ready to go.

IBM ThinkPad... | Answered on Mar 03, 2011

This is the IBM description of the error -
Normal 0


Bad CMOS/NVRAM checksum


Bad system configuration



Go to the BIOS configuration - the Date and Time may be wrong.
If this does not fix the problem try setting the BIOS bacj to the defaults.
If this does not fix the problem, the BIOS battery may be worn out and needs replacing.
