Unable to "Standby" my ThinkPad T23 Laptop

Hi,

I have an old IBM ThinkPad T23 laptop that I use every day.
I normally keep it on for hours. Therefore I use the AC adapter
all the time. It has WinXP Home Edition SP2.

Unfortunately, if I click on the "Turn Off Computer" at "Start"
button, the pop-up window allows me only 3 of 4 options:

"Stand By" is NOT enabled!!!

"Turn Off"

"Restart"

"Cancel"

Note: My Gateway desktop computer's "Stand By" is enabled (same WinXP
version).

How can I enable "Stand By" on my ThinkPad T23?

Thank You in advance, John

You might need to use dumppo.exe and do an override.

Stuff like this can happen, if you have a BIOS with
ACPI settings.

S1 only --- screws up Windows, needs dumppo.exe to repair
S1&S3 --- preferred, allows sleep

There might also be an ACPI version setting (of all things).
Make sure the ACPI version is set to the highest value listed,
for best compatibility with your OS.

This tool doesn't work in Windows 10. It's only for older OSes,
if at all. It's hard to say how many more years this link is
going to work. The program is only 12KB or so, it's tiny,
and should have been put on the OS installer disc.

ftp://ftp.microsoft.com/products/Oem...cpi/dumppo.exe

Here's a scan of dumppo.exe from the FTp site.

And an alternative download location.

The Bellamy copy is clean, even if it appears to be
a different version of the previously available Microsoft FTP copy.

DUMPPO.EXE admin /ac minsleep=s3

Use the "dumppo admin" command first, to review whether
an override is even necessary. As it could be that
something else is broken (hardware-wise).
