Damage to Power Settings / Options Win 7 Home Premium x64 ?

Gang
I'm doing a repair on a dell Inspiron notebook, shipped with Win7 HP x64 preinstalled. Its about a year old roughly, and was terribly treated by its owner
So it is taking me awhile to kill trojans, pull malicious code, etc.

One question I have since I generally know Ultimate better than the others: In Home Premium is there no distinction between Power Plan Settings for Plugged-in versus Battery ? I don't see any such. Not pulling up and I'm looking at the advanced settings...

If this OS is damaged, will running the Repair console from F8 be sufficient, or shall I go ahead and use my lab mule x64 Ultimate to spit out a repair disc and start from there? I suspect a lot of damage. There were myriad registry errors after the first pass of using MBAM and HJT to sweep the easy ones.

I would use the Recovery Partition to do clean install.

If it's any help to you, I set up my neighbour's new Dell Inspiron laptop today. It had Windows 7 Home Premium pre-installed and definitely had separate power-plan settings for battery and mains power operating.

Do you have a set of recovery discs for it or is the Dell recovery partition still intact? If so I'd be inclined to just bite the bullet and do a factory restore, it'll be quicker in the long run and you'll start off with a clean system again.

you may well be right my friend. thanks for responding.
question: on the one you saw, was the recovery partition marked as "Q" ?

the restore was definitely the good move.
I am a critic of dell for many things [worked there also], but on the restore function, their customized
touches work, are lean, plain, protect the valuable files [which could be infected, btw], and results in a
good system that just needs the usual cleanup of bloatware, mcafee, etc, and fine-tuning.
lousy notebook - but good custom software!

Pleased to hear you were able to restore your Dell so thanks for keeping us up to speed with your problem.

One of my boxes is a Dell Studio XPS 8100, which I'm quite impressed with. I did have a problem with it recently in that the CPU cooling fan kept cutting in even when the machine was idling.

Luckily, Dell had provided me with a free 2-year pick up and return warranty. I called them at 10 a.m. and they had a repair agent in my area who arrived within two hours and replaced the motherboard, CPU and cooling fan. Very impressed with that service, I must say.
