Dell inspiron adapter issues

Post by Gwen Mors » Sun, 28 Aug 2005 07:04:19


I get the following warning just after the BIOS loads, on my Dell
Inspiron 8200:

WARNING: 70 Watt (20v,3.5A) AC adapter detected. System will not be
capable of running in full performance mode without a 90 watt (20V,
4.5A) AC adapter. Press F1 to continue in battery optimized mode, or
F2 to shut down.

However, I do _not_ have a 70 Watt adapter. I have two 90 Watt
adapters. Both are reasonably new (less than 3 months old). There is
no pin damage on either the laptop or the adapters.

My laptop is about to go into Dell for the second time, to "fix" this
problem. The first time they changed the fan/power supply. This time,
they're supposed to replace the motherboard.

Does anyone know what could cause this, _OTHER THAN_ a weaker/damaged
adapter? The tech support guy I talked to didn't sound very confident
of his own diagnosis and it sounded like he chose replacing the
motherboard because he just didn't know what else to try.

I've been thru this more than once. Had two power adapters replaced, then
MB, then adapter again. My impression was that bad PA would blow the MB, and
vice versa. Still, it sucks big time... one of reasons why I got rid of that
Inspiron.

I've come across this before, on various laptops. Dells cope with it by
dropping the power consumption. Toshibas, Acers and others cope by
burning out. The problem is bad tracking on the power circuit. I fix it
with silver solder poured over the track between component contacts.
Tricky to do without a flow control system, but doable.

Would replacing the motherboard deal with the ball "power circuit"?
(is the power circuit located on the mb?). Or, is there some sort of
separate repair that would need to be done?

Repairing is the best option if it's caught early enough (ie the board
hasn't already been damaged). Getting the motherboard replaced outside
of warranty is almost as expensive as buying a new laptop.
