I am having problems starting up my computer

[cinque8]

Hello,

I am having problems starting my computer. My computer boots up but the display doesn't turn on. I have to hit the on/off button 10 to 15 times before the display finally turns on. Can anyone tell me why this is happening?

Thank you

@cinque8, welcome to the forum.

What is the full model of the computer? I need this information to review the specifications of it. Please don't furnish the Serial # or other personal information.

Thank you for the additional information, @cinque8.

Here is a guide to help you test the battery.  If it hasn't been replaced recently, it could be failing.  Also, it could be that the power adapter is failing.

Here is a guide to help you test for hardware failures.  The age of the laptop makes it likely that any of the components could have failed.

You are welcome, @cinque8.  It will give you a good place to start troubleshooting.

Hello Old Geekster,

I downloaded the HP PC Hardware Diagnostic Tool. The drive failed the short and long tests.  The battery test canceled on both tests. And everything else passed.

Thanks !

Also, I ran the Sea Tools long genric test, and the hard drive failed the test, but the hard drive seems to work perfectly.

Thank you

@cinque8, thank you for the additional information.

The tests are telling you that your hard drive is failing.  It gives you a heads-up so you can backup your personal information.  This is actually a great feature.  I only had to lose all of my personal information once to make me a believer in doing backups.

Here is the Maintenance and Service Guide for the laptop.  In Chapter 4, Removal and replacement procedures, Page 78, there is a list of compatible hard drives and SSD's.  Also, the relacement procedures.

Thank you again for the information Old Geekster !

Any idea why the battery check canceled?

Thank you
