Question about Compaq ( 277498-001) Motherboard

1 Answer

Dead motherboard? I own a Compaq NX7010 laptop. A about a year ago, I upgraded the bios when the hard drive died so that I could install a larger hard drive. After that, about 3 months ago, I upgraded the memory as well, to it's maximum (2G). Everything was fine until about 4 weeks ago, when I went to boot it up, and got a blank screen. At first I thought it was the screen, but I was hooked to a KVM switch at the time, and realized I was getting nothing on the monitor as well. So then I considered the graphics card, until I realized that none of the controls appeared to work. For example, the wireless indicator was lit, but pushing the wireless on/off button did nothing. The keyboard did nothing. The volume control - nada. I could hear/see the fan spool up, and I could hear the cd drive spin up and then stop as normal. I was not sure about the hard drive. I removed AC, removed the battery, pressed the power on for 30 seconds, removed and reseated both the new memory and the hard drive, put it all back together...nothing. And then it occurred to me that I was not even getting the POST screen. So, that would seem to indicate the motherboard is toast, right? My question is, what are my options here? Any help would be greatly appreciated.

    Thanks for the help, people.



    So, would I just replace it at $400, get a "repair kit", or just get a new laptop? I know that is more a matter of opinion, but just curious what yours would be.

    Well, I don't readily have a voltmeter handy, but would that really cause that? And so sudden? Literally it was fine one day and dead the next.



    I should point out that as I removed the memory, I tried booting it up and got the same results. So I know that the memory is not the cause.

    If it were mine and the power supply was good, that would mean it was either the processor or the board or both, the rom chip may be the culprit, so I think it's resonable to try replacing that first if you are getting the proper voltage out.

    A voltmeter would be the way to go, it may just be a power supply.,also the bios rom chip could have went, here is a site that you can get a replacementhttp://www.bioschip.com/

Try removing the memory one by one try that first if that does not resolve then It would be your motherboard.

    If you just replace the motherboard depending on the cost of the labor it would be cheaper to go with replacing the board but if you want a reason to get a new laptop that would be sufficient also.

Just replaced my hdd on Compac Presario 2100 but the system is not detecting it.


This model laptop came with a 60Gb hard disk and if you installed a much larger capacity hard disk then the BIOS cannot detect this hard disk.
For the BIOS to detect a large hard disk a BIOS upgrade is required (if there is one available) Check the HP/Compaq WEB site to see if there is a BIOS upgrade.
If not the try a 120Gb or smaller capacity hard drive.
As an alternative -
You can keep the existing hard drive in your laptop and use an external USB hard drive to store your data.

On the BIOS set up, it will show HDD (none) but if i return the old one the system will detect it.


This model laptop was installed with a 60Gb hard disk. When you installed a much larger hard disk the BIOS could not detect this hard drive.
Check the HP/Compac WEB site foe a possible BIOS upgrade that can support a large hard drive. Otherwise try a hard drive 120Gb or smaller.

Unless Dell has the upgrade for the bios to include the larger hardware you are going to be in trouble, I would go online to Dell and check for upgrades to your model if they still support it. The other option is contact customer and technical support to see it they can give you a alternative solution.

The maximum hard drive you can install depends upon the BIOS. You MAY BE able to install a larger hard drive if the BIOS upgrade will allow it. I suggest you go to the Gigagyte WEB site to check on this possibility.

What's the maximum hard drive I can install in a Compaq SR1420NX I have a 80 hard drive right now I want to install a larger one. Will this computer handle a larger Hard Drive


The BIOS has a max. hard drive size limitation. Check the manual for the maximum size the motherboard can support.
If the maximum size hard disk it can support then you can add a second hard drive in the computer as a SLAVE hard drive to double your disk space capacity.

External HD device driver for Compaq Armada E500


First, try the external drive in some other "recent" computer.
Use the other computer to "format" the disk-space,
and thus make an "empty" partition. Then, reconnect it to your computer, and see if the total capacity of the drive has been detected.

According to the manufacturer's web-site:

http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=96717&prodSeriesId=96231&swLang=8&taskId=135&swEnvOID=1093

this computer dates from 2001/2002. So, the claim of a maximum of 32GB probably is correct -- drives larger than 32GB were either not-available, or were prohibitively-expense, nearly 10 years ago.

Download the latest BIOS-update from the above web-site, and CAREFULLY follow the instructions to update the BIOS.

However, you have not said what happens when you connect the external disk-drive, as a USB device. It *MIGHT* work "as is", i.e., without trying to update the BIOS.

Nx7010 does not start.


Hello dear, probably some BIOS values changed, causing u no displays. Try this key combination immediately after startup

esc - loads bios, but not in display
F9 - (hope its F9 in ur laptop) resets BIOS
F10 - saves BIOS to default values and exits
RESTART

Or else try removing CMOS battery, its right beneath the keyboard. (Just remove 1 screw) Remove and hold for 1 minute and then reinsert and turn up laptop on. Your PC should be fine.

NP Nx7010 restarts itself.


your NP Nx7010 is always restarting. that part is having some trouble with your hard drive. or the partition which called the NTFS not function or unknown anymore to find the system inside your hard drive. let your technician ask or try to remove your hard drive and run it to another pc.
