Problem with Standby / Hibernating

My Toshiba notebook (Satellite Pro 4600 running Win XP Pro) has worked well for over 2 yrs. I very often use "standby/hibernation" when closing my PC so I can quickly get working next time, and this feature has worked reliably, until recently...

A month ago I changed my p/w and (coincidently?) hibernating the PC started to cause me problems. Now 75% of the time when I start up again from hibernation I get an error saying the restoration file can't be read and I have to reboot from scratch.

As part of this error msg there is a kind of DOS window that flashes by so quickly I can't read it - but one thing I can catch is something like "The BIOS is not ADPI(???) compatible... "

Not sure if it's a h/w, s/w, BIOS or other problem. There are no other problems with my notebook and I religiously run the latest Virus checker - with no reported problems.

Can't understand why sometimes I can restore from standby but most other times I can't...

Have checked Toshiba's support site and other web references but haven't found any help on this.

Sure would appreciate any ideas and suggestions on how to fix this annoying problem.

 

Would that be ACPI?
Advanced Configuration and Power Interface.
I'm afraid your hibernate function may not work again. It is going into hibernation before the restoration file is written.
Do you have any problems Shutting Down?
Would this p/w be the Power Supply?

 

Thanks for the reply markp62.

The 'DOS' screen may have said 'ACPI" - not sure since it flies by so quickly - I'll check next time I see it.

By 'p/w' I meant 'password'. The very next time and thereafter after changed my p/w, hibernation became unreliable.

There is absolutely no problems shutting down - everything happens as it always did...

Three things puzzle me - 1) what has changed to make hibernate unrealiable, 2) why does it work intermittantly and 3) what can I try to gte it working properly again?

Rgds,

P.S. BTW, just in case it was a battery problem I changed the battery but this provided no improvement.

 

Looks like I may have solved this problem and it turns out to be intermittant RAM.

One of the RAM modules (not sure why - bad chip, bad connection...?) was flakey and sometimes would provide an addl 128M of mem and sometimes not.

On that basis - my theory is - if the notebook went into hibernation with this extra RAM working (or not working) and then when it work up from hibernation with the RAM in a different memory configuration the restoration file data would appear was corrupt (ie, not properly map against what was stored in the standby/hiberation file vs the actual h/w mem conditon) - and therefore the restore would fail.

I have removed the 2nd mem module and standby/hibernation has been working perfectly the last several days.

Hope if anybody else experiences this problem this will give them some good ideas.
