I have a number of dell e6400 laptops.
Recently units have been coming in for repair from various offices with the complaint that they are running slow.
These units could take 1min or more to open task manager etc. The boot up time is fine but loading apps is painfully slow. In other words it isn't just 'user expectation but they are slow....
Reimaging the machines to our base image seems to temporarily fix the problem. (IE - it would appear that a user adding software makes it slow)
However roughly a week after being imaged the units are coming back performing with the same slowness with no apparent software changes.
Av scans from multiple tools are clean, windows patches are in, bios is up to date. hd tune utility benchmarks the drives as 'fine' or within the expected values of a new drive.
Machines also have intel speed step which is turned on. (correct 90watt ac adapters are also being used). There is no smart reporting in this particular dell model.
Could the hard drives be performing noticeably slower after three years of use and if so how can i test an existing hard drive against a new warranty hard drive? Baseline/benchmark software?
Thermal issue? Many have 'plugged' fan exhausts. The unit is opened and cleaned and new thermal paste applied. Heat damage before the cleaning?
Any insight into pinpointing or baselining hardware to help determine part replacement is appreciated
