Replacing lcd screen on a hp dv6 laptop

Image
I have replaced several lcd screens on the laptops in the past replacing screen on a hp dv6 laptop however was not that straight forward.I had to dismantle the entire laptop to get to the broken lcd.Here is how you get to the lcd.

Screen : Samsung ltn156at05 5kak55804n H02

DirectorySearcher PropertiesToLoad Add is not working

If you have played with or is using System.DirectoryServices.ActiveDirectory, you might jump into the consclusio that "DirectorySearcher PropertiesToLoad.Add " is not working/useless/will be ignored.But that might not be the case.

Lets see a sample, this sample below tries to get the list of users with their user name, first name,last name and email.

  Private Sub LoadUsersForDomain(SelectedDomain As Domain)
        If SelectedDomain IsNot Nothing Then
            Dim sentry As DirectoryEntry = SelectedDomain.GetDirectoryEntry
            Dim Searcher As New DirectorySearcher(sentry)
            Dim srs As SearchResultCollection
            Searcher.PropertiesToLoad.Add("samaccountname")
            Searcher.PropertiesToLoad.Add("GivenName")
            Searcher.PropertiesToLoad.Add("sn")
            Searcher.PropertiesToLoad.Add("Mail")
            Searcher.Filter = "(&(objectClass=user)(objectCategory=person))"
        …

Results from Active Directory search query doesn't contain all the objects

If you are wondering why AD search didnot return all the results, the answer is there is a limit of 1000 records per search.This is the scenario we had:

We have many sub domains on the network like
a1.test.com
a2.test.com

We have users under a1.test.com like a1\user1a,a1\user2a . . . .
We have also users under a2.test.com like a2\user1,a2\user2...; also we have rda2\user3 rda2\user4....;
I dont have lot of knowledge about "AD" structure or the terminology.I dont know how the rda2\user3,user4 ended up under a2.test.com

My user is rda2\user3 and if look at the user domain using the "set" command I get a2.test.com, my user dns domain is rda2.

The problem is in my windows app I am trying to show the list of users under every domain
It shows somethings like this in the treeview
a1.test.com
a1\user1a
a1\user2a
a2.test.com
a2\user1
a2\user2
But users rda2\user3 and rda2\user4 is missing from the list.

I use the following code to get the list of users.Also I use the windows …
