Gateway 7405gx boot failure

I have a Gateway 7405GX that started having boot problems over a year ago.
At first it was a very sporadic problem but over time happened more and more.
As I recall, it would not boot and give an error regarding the boot device; I could hit F1, enter BIOS setup and then exit and the system would boot fine. Running a chkdsk showed no errors.
So, for a year or so I would use the system this way, until the problem advanced to a point where I can’t get into BIOS or boot.
I figured the BIOS or mobo was the problem and replaced the system. Lately I’ve started wondering if it could be as simple as replacing the CMOS battery, something that seems relatively inexpensive.
I feel like I never got my money’s worth out of this machine and it’s the only machine I’ve got that’s compatible with my Protools setup, but want to fix it myself and don’t want to spend hundreds on it.
Any ideas MUSC appreciated.
Thanks!
Dan

    url below has the "post beep codes" ...only one that matches is the "phoenix codes"...

    you may have to unplug and remove battery to and put battery back in and try "fresh start" to get the beep codes.

Hi Dan -

On this particular Gateway series of laptops, there is actually a bios "chip" you can replace entirely. It's sitting in a cradle right next to where the keyboard connects to the mobo (square black chip, one angled corner). It's very easy to pop out and replace, and is definitely something I would try.

You can do a search on eBay for "gateway bios chip" and you should have some luck.

I hope all goes well.

Gateway 7405gx laptop will not load windows .goes to log on screen for user . click user and loads and then shuts down saving settings. tryied in safe mode and does same thing.


There is problem on the user account, or the hard drive. Try login as administrator. If the problem still occurs you need to reformat your laptop or try the recovery disk or option of your laptop. Or try changing the hard drive. But still, you need to re-install or try the recovery option or the disk.

We have a gateway laptop model 7405gx and the battery light is blinking even though it is plugged in. Do we need a new battery? What kind is it? thanks. Judy


Does it still work fine on battery?
If you remove the power lead when the battery is in does it shut down.
If so the batery is probably gone.
Replacement bateries are expensive £77 here
