At that point, I was left with two options; buy a new laptop at a cost close to plus set up time or send my laptop into HP, pay close to and wait 4-6 weeks. Thanks to ScreenTek I was able to save close to dollars have the screen sent to me in two days and with help from a local repairman be back to work. Great Job!"
