Sluggish performance on laptop after coming out of sleep

I tried searching this and didn't find much so I figured i'd ask. I know i'm running an older laptop but lately when I come out of sleep mode everything I do is more sluggish and slow.. and web browsing especially. Most of the time I just have to do a restart to normalize it. Has anyone heard if this is an issue or is it just my old laptop? I've done security and malware scans and they don't find anything. All updates are current etc.. I tried turning off all extensions on the browser also.

Dell Inspiron 1545
Upgraded to 8gb ram (which is overkill for this pc to begin with)

I just like to solve things like this instead of scrapping it and moving on.. why it would be sluggish after coming out of sleep and not on a full start up.

Are the drivers up to date, especially network adapters?

All drivers are current.
