Hi.

The part is called "hard drive caddy" and it is not expensive. Here one example: 1144T - Dell Inspiron 2100, Latitude L400, Check also on Ebay.

Try installing the latest LAN driver first.
You can download the device drivers from Dell WEB site,the support download page. Make sure you select your model desktop or laptop,better still, type in the Service Tag number, it is printed on the label on thebottom of the laptop and on the back or sides of a desktop. (If the Service Taglabel is missing then go into the BIOS setting and on one of the BIOS pages,the Service Tag number will be displayed). This will open the page where thespecific drivers for your model computer are located. Also make sure you selectthe Windows of the drivers for your Windows operating system. Click on thislink to download the drivers: - http://support.dell.com/support/downloads/index.aspx?c=us&l=en&s=gen
If the LAN card is faulty then the built-in LAN card cannot be replaced, BUT you can purchase a PCMCIA LAN card and insert it into the PCMCIA slot to replace the faulty built-in LAN card.

Hi,
Please do one thing remove the battery and the power cord at the same time andkeep the power button pressed for about 20 seconds and then try restarting yoursystem with the power cord plugged in. If it works then plug-in the batteryalso for normal use. If it doesn't work try reseating the memory from thelaptop. If you cannot do it yourself please take the help of a local tech oryou can ask me for the instructions, please let me know and I'll guide throughthe testing procedure,

Sounds like you need to reinstall your display drivers.

go to BIOS by pressing F2 on dell logo, then go to Boot Menu, make hard drive as the 1st boot device

just reinstall windows..without formatting..this will keep all your files and programs ...( some of the programs will have to be reinstalled to work with the new sys32 ) but in general will be just fine...if we are talking about user password and you are able to boot to the bios at least to boot the installing from the disk process...

A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective.

There should be an access panel on the underside (usually the larger one)

Problem is that the machine is not communicating with the CD-ROM. You can solve it by following these steps:

When the message appears, type: Shift+F10 to enter a command session.

Type: regedit.exe at the prompt.

Highlight the HKEY_LOCAL_MACHINE entry.

Go to the File menu and choose Load Hive.

Then, load %Windir%\System32\Config\System.sav
Give it a short name that you will remember, like "Test".

Then, find this key:
HKEY_LOCAL_MACHINE\Test\ControlSet1\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Delete UPPERFILTERS and LOWERFILTERS keys.

Do the same for ControlSet2 and any other numbered ControlSet keys you see.

Hi there.
Remove the battery and try it on AC power only, if it boots up turn it back off and put the battery back in again and power it up again, if it boots up, the cause will have a small surge from the power strip caused by the thunder storm.

Good luck and thanks for using Fixya!!

There are a number of reasons that the unit could be freezing up.

1. Corrupted file(s)
2. Low available disk space
3. Viruses and/or malware
4. Too many add-ons/toolbars/etc.
5. Heat build-up

Number one is the hardest to find. So start with #2. The computer needs free hard drive space to operate. If the disk is nearly full or is very fragmented, this can slow the machine to a crawl. Check for available space and if there is plenty (20GB or more), then check for fragmentation under administrative tools. If the defragmentation tool recommends optimization, allow it to perform it and see if that helps. For viruses and possible malware, run your virus scanner. It is always a good idea to get a second opinion on such things. Malwarebytes is a free malware scanner that works very well to find adware and some things that many antivirus programs fail to detect. Many user feel that they have to have every bell and whistle. I've seen some browsers with 7-10 different toolbar add-ons. These almost always come with some adware and always slow down the browser. Uninstall all but the most essential toolbars for the best performance. Heat is a slayer of machines. Laptops are very susceptible to heat issue since they are often placed on beds, sofas, carpets, and yes, even laptop. Many of these units draw cooling air from the bottom and exhaust it to the side. Even those that draw air from the rear and exhaust to the side will often intake large amounts of dust, grit, and lint. These can partially or completely clog the heat sink unit and cause heat buildup of the processor. This will cause the processor to work slower and can actually cause it to thermally lockup, resulting in the need to reboot. Many units can be accessed to clean with a removable cover on the bottom; others may need to be serviced by a technician to clean.
