Alternates between AC and Battery power

[fornewsgroups]

my laptop keeps "switching" to battery power even though the AC power
cord is securely attached to the computer. I then just simply unattach

then reinsert the cord. Although Compaq think it is a hardware issue I

find this hard to believe since if I try to purposely "loosen" it it
does not switch to battery. IT just seems to happen randomly.

The timing is such that it seems to be a recent windows update.


Suggestions? Thoughts?


I did find this post which describes a similar issue:

(although I do not have a separate charger).

It could most definitely be a hardware issue. The laptop must have some type
of detection component in order to know when the power cord is connected.
This seems to be failing.

Well, I did a repair of the operating system (windows xp home), and so
far so good.
I don't get it, but again so far so good. If it changes I'll post it
here. But if anyone else having this issue, try a repair of the OS.

Sigh,
scratch the repair remedy. At first it seemed to work as it didn't
"switch" for hours and hours. But turning it on this morning, it
STARTED on battery power even though the AC power was connected.

OK, scratch the scratch. This is the longest it hasn't "switched"
over. So maybe it has "healed"?

WEll reformatting didn't work. It's happenning again.
When I pull the plug out of the PC, it is quite hot. Is that suppose
to me?
Is there a way to determine whether it is the plug, or the PC?
Thanks

Speaking with Compaq, the seem certain the issue is the DC jack of the
notebook (claimed it is a known issue). Does this sound right? If so,
is this expensive?

I'm having the same problem. My computer keeps switching from using the AC
power to the battery even though the power cord is still connected. Is there
something wrong with my computer or is it my power cord?

I would look to see if the power adapter has a light that shows if
it is active. If the light is staying on but your laptop keeps
switching to the battery, then I would suspect the actual power cord
jack. A number of manufacturers are noted for having poor solder
connections of the power jack to the motherboard.

For more information, I would recommend going to comp.sys.laptops
with the specifics on your laptop.
