Laptop Hard Drive Switch on Same Model Laptop

An HP Laptop screen went dim all of sudden. When connected to an External Monitor, display shows up fine and bright on the External Monitor.

So I took the hard drive out of this dim screen HP Laptop and put it into another same model HP Laptop (model - HP Pavilion DV7-3188CL).

This HP Laptop with the dim HP Laptop Hard Drive booted up successfully and display is clear and bright.

Will there be any problems ?

Thanks.

Eventhough it is the same model, you may some small hardware changes.  Check the device manager to see if you have any driver issues.  otherwise, you should not have any issues.

Hi rtay,

There are no issues in Device Manager.

MS Office works properly. Upon checking, MS Office License is already activated.

I had 1 issue:
Upon opening MS Outlook while it was downloading mails in the Inbox, I opened Sent Items folder in another window. After a few seconds, mouse pointer and keyboard froze.

What I did after this:
Killed power and rebooted.
It started in Safe Mode
Rebooted it
Went to Bios and set to Defaults
Rebooted

I now have Outlook open.
Keyboard and mouse pointer has not frozen yet.

Please advice.
Thx.

You could run sys prep to redetect hardware - you would need to reactivate Windows.

CSI-Windows_com,

I did not have to run sys prep and reactivate windows.

Both Laptops are HP Win 7 Home Premium bought at retail from Sams Club.

I've kept the Laptop running for the night and will get back to you two.

Thx.

you can look if the model is the same (on the bottom)
if the same model = no problems
different model -  you can have slight hardware variations.

the  only problem you WILL have is you cannot transfer the Windows from your OLD laptop to the NEW one, OEM versions will fail on activation, since the hardware and software are tied together
