Over two years ago I ran into the power connector issue (weak solder point on the mother board). At about the same time, the LAN icon disappeared from the task manager section on the bottom right. Now, of course a short in the system could of fried the nic adapter but I'd like to perform some troubleshooting and am asking for ideas.
Windows XP SP3 Kaspersky AntiVirus (Norton and McAfee can go shove it)
Behavior noticed in the meantime: 1) For a period of time the nic would show after a reboot and would remain until the next reboot. Not a guarantee it would show after each reboot. I had a hdd failure and had to have a new one installed and since then it hasn't shown once.
2) Hardware Manager shows no ? and no LAN is displayed with my WiFi adapter under Network Adaptors.
I'm thinking that maybe this is a driver issue and for some reason the older driver isn't playing well with some windows updates or maybe the hw had taken a hit dur to the known power issue. If it's the hw then I'm SOL but if it's a driver issue I was wondering if someone would know of it.
NEW INFO: 1) When I go under Network Connections in Control Panel I do not have a Local Area COnnection. 2) Hardware Manager doesn't show a LAN under Network Devices. No ? are shown either. 3) I'm sure this isn't an "icon display" issue. 4) The adaptor itself doesn't show any lights. The link/status LEDs are not blinking or anything.
NEW INFO 06/14/08: 1) Opening cmd prompt and typing ipconfig only displays information on the wireless network adapator. No information is displayed for a lan network adapator.
It's kind of like the LAN hw itself isn't even recognized by the system as being present.
Thanks!

There is a check box to turn that icon on/off. It's in the Local Area Connection portion of Network Connections and there are several ways to get to it.
(1) Right click My Network Places on the desktop and choose Properties.
(2) Click Start -> Network Connections
(3) Go through the Control Panel.
No matter how you get there, you will see an icon for Local Area Connection. Right click that and choose properties. Near the bottom, you will see a check box to "Show Icon In Notification Area When Connected". Place a check mark in that box.
Now, if it's already checked and you still don't see the icon, try unchecking it, click OK to get out, then reboot. After that, go back and turn it on again.
I'm not familiar with the ZV5000, apart from all the stories I've read about them, so I'm unfamiliar with the steps required to remove/refit hard drives to this particular chassis.
If the replacement required disassembly of the fascia, perhaps the NIC connector became dislodged at that time?
I've checked the hdd and it's easily removed without opening the laptop itself. Good idea that somehow a connector got loose though. The warranty is expired and I've dismantled a number of Dell and HP laptops in my past so I'll give it a go on this one.
I noticed the nic is on the opposite side of the hdd so it's doubtful anything happened that would cause a loose connection. I double checked though and removed the side plate that would expose as much of the nic side of the laptop as possible. From what I saw, the NIC is soldered to the MoBo without any external connectors. Looks like the NIC is fried somehow or maybe I'm missing some critical driver (even though I reinstalled everything from HP).
I checked BIOS and there is not option for disabling/enabling the NIC. I know what you are talking about as the BIOS in my desktop PC contains the option you mentioned. Apparently the BIOS for the laptop doesn't provide the user with that configuration option.
Forgot to answer your original question. Device Manager doesn't show a LAN network adaptor. It shows the WLAN (WiFi) network adaptor and no ? are shown indicating that adition hw was found but no compatible driver was found.
If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem. Also please exercise your best judgment when posting in the forums--revealing personal information such as your e-mail address, telephone number, and address is not recommended.
