why network adapter not working after reset cmos battery?

Hi experts,

I got a problem with network adapter. It happened after I took out the cmos battery and put it back in.
 
After I restart the computer, there is a message saying that the network adapter is experiencing  driver - or hardware - related problems.

Then I went to device manager and click on the properties of the network adapter, it says "This device cannot start. (code 10)".

Could it be hardware failure? or something in BIOS make it cannot start. I tried to update driver and saw that "Windows has determined the driver software for you device is up to date."

Then I used a wireless adapter through usb but computer could not install the driver for it. So, it looks like I cannot get internet access.

Please help.
Thanks,
RDB

You could have a hardware failure before you changed the BIOS battery. I have not had to do such a thing on some decades.

You could have damaged the BIOS. Can you get a BIOS upgrade ISO on another computer, burn it to CD and see if you can update the BIOS.

I reset the whole computer to the factory original setting. the network adapter still not working. could that be bios problem?

if we reset everything to original factory setting, isn't that bios got reset to its original setting too?

I used a cd to install driver for the wireless adapter and it gives me internet access for now. but still like to fix the build-in wired connection.

Reset to factory specs does not usually reset the BIOS. After the factory reset, does Device Manager still tell you the LAN card is still not working? It is probably part of the Motheboard. It may be worth trying and add-in NIC

Try getting into the BIOS and reset everything to default, if you haven't already.

Next, boot into Safe Mode and run sfc /scannow from a command prompt. Could be you got a corrupt system file that's keeping the driver from loading properly.

ok, the network adapter still not working after factory specs

So, what is a add-in NIC?

Remove the Network Adapter in device manager and scan for new hardware
Re-install the adapter. You can let windows find it but I'd say to download the driver and use that instead.

An add in NIC is a separate (say USB) LAN card.

Is this an adapter on the motherboard?

Then I used a wireless adapter through usb

Also, when you replaced the BIOS battery, you may have done some electrostatic damage to the main board. This is another reason to try a USB network card.

now the usb network card is working.

However, not matter which website I go to, it warn me about the security setting. Even simple website like yahoo.com. the website's security certificate always come up. It looks like I cannot go anywhere, and cannot do windows update.

Does this sound like a motherboard setting problem too?

I did go to bios and set everything to default.

From farther back "I reset the whole computer to the factory original setting"

However, no matter which website I go to, it warns me about the security setting  <-- It would not seem to be operating system if you reset to factory settings (which reinstalls the operating system).

So it could be some damage of some kind when changing the battery.

Paste a screen shot of the security setting
- Your current settings probably does not allow cookies or does not allow certificates to auto install.
Try accessing a website that does not use certificates (http:// instead of https://)

For sites with certificates, click on the error near the address bar and install the certificate

You may also want to try installing firefox or chrome. If unable to install from site, just download the installer from another computer to USB and install from USB

Many BIOS have settings where you can enable and disable onboard LAN controllers. Usually you can also change a setting there so the system boots from the LAN. The BIOS, when removing the CMOS battery, would have returned to it's default setting, and the default settingmight be the LAN controller disabled. So check through your BIOS settings and make sure the LAN controller is enabled. Also make sure Boot from LAN is disabled.

The other problem is more of an issue with your OS, and not BIOS or mainboard.

That's why I suggested you boot into Safe Mode and run sfc /scannow. Sounds like you got some corrupt OS files and that should help fix it.

ResourcefulDBAuthor Commented:
ok, the internet work fine now. still cannot network adapter yet.

next I will see if it is corrupt os file.

how do we boot to safe mode and run scan?

what is sfc?

SFC = System File Checker . Run SFC /SCANNOW from an admin command prompt.

Have you confirmed that the date and time is correct?  Certificates can fail if it is way off.

As far as the LAN card goes, check the BIOS for the setting about a PnP operating system.  While it should be set to "Yes", if it is already on that, try "No".

I thought you did a factory fresh reinstall. Please clarify.

When you first turn on the computer, start hitting the F8 key and a boot menu will show up and you can select Safe Mode. It loads a stripped down version of Windows with minimal drivers so its easier to fix issues.

Open a command prompt and type "sfc /scannow" and let it run. SFC is the System File Checker. it's built into Windows and there to find and fix corrupt system files pertaining to the Operating System. It will fix corruption and things like that.

@john, yes, I did a factory setting restore. in lenovo, just hit f2 when start and there is an option there to restore everything back to factory setting.

It seems unlikely to be an operating system issue in this case.

rindiCommented:
Have you like I told you, checked in your BIOS whether the NIC is enabled?
0
JohnBusiness Consultant (Owner)Commented:
With all you have said (Fresh Install, Battery replaced = possible electrostatic damage), BIOS setting (as rindi noted) is the only possible thing other than a hardware problem (so it seems to me).

Also, check the motherboard for any blown capacitors. If any of them are puffed up on top or have some brownish-yellow crust around them, it's a bad sign.

like rindi said the onboard network may have been disabled in the bios, by removing the cmos battery (but usually the default settings is to enable to onboard network card, which occurs when you remove the cmos battery). If you are positive that it is enabled in the bios the next step would be to look in the device manager to check to see if the network card is listed in the list of network adapters, if it is not seen there then it is still not properly enabled in the bios or the network card is dead.  If it is seen in the device manager and has a yellow question mark you need to install drivers for the network card and will need to go to the manufacturers site to download the appropriate driver.

yes, there is a yellow question mark on the device manager. did not see any blown capacitors in motherboard.

@web_tracker
I thought the driver for the network card should be back after factory setting restore.  Or it is not necessary the case.

You did a factory restore which would bring back a working network card, so I think you have a hardware issue.

@ResourcefulDB - Thanks and I was happy to help.

the factory restore has nothing to do with settings in the bios, the factory restore only re-images your hard drive so that it has exactly the same software and setups as was originally installed when you first bought the computer, this has nothing to do with the bios settings at all. the bios and the hard drive are two different things. If the network card is not seen in the device manager, then either the network card is disabled in the bios or the network card is dead. If is shown in the bios with a yellow triangle then you need to install drivers for it. If it is seen in the device manager and is shown in network devices that means the drivers were successfully installed and the network card should work unless it is disabled.
