Hi!

I have an old HP notebook, that has been broken for about 3 years. The SN is CND80779KH. I can not get a spec list unfortunatly as the laptop screen doesn't work and the laptop battery is dead. I will try to charge it sometime today and see if i can gtlet it to boot. A friend and I both suspect broken backlight on the screen. The back panel is out of alignment with the keyboard, which I have attached photos of. The warranty ended in 2019, but I am wondering if it is worth trying to fix this laptop. If it is not worth fixing, I will use it as a training dummy for learning to open laptops and fix them confidentially. 20250318_103435.thumb.jpg.95bff85e74009edbe77d6d019aabe9a8.jpg20250318_103739.thumb.jpg.bb4f8b2f11beced022c537ef6a5992c2.jpg20250318_111807.thumb.jpg.046ab2eb7117f0bbb93ba31a02e1e3fb.jpg

Yeah that's what I thought, just wanted to confirm in case there was some hope of fixing it. 

 

If it turns on at the screen still works you can just get some jb weld and epoxy the hinge back to the screen. It works pretty well surprisingly. Wont be worse than the plastic mount hp uses

The cables connecting the screen to the motherboard are damaged. (Probably caused when the hinge ripped apart.)

 

If it has an HDMI port, connect it to a TV or monitor. It will probably work fine as a stationary computer.

 

It's not worth the cost to fix, unless you can find an identical model that has a bad motherboard. Then you can make one good laptop out of the two broken ones.

I sold my soul for ProSupport.

Ok that's interesting

I did wonder if there were some cables damaged

I'll try connecting it to an external monitor this afternoon when I have it charging. 

Thank you!

Not worth it to fix, imo. You can look on eBay and usually find an upper screen assembly for those older HP's for less than $80. Then it's a simple swap. But you'd want the whole assembly with hinges and cables and everything. Battery is going to be around $30 on Amazon. Plus the time you'd have to put into it to replace everything, if it has a standard mechanical HDD it would be best to get an SSD in it as well. At that point you'd be putting the amount of money needed to purchase a refurb/used probook into fixing it. Might as well just get a more up to date probook on ebay for $150 to $200. Unless that one you have is a 9th gen or newer i5/i7, it's not worth putting any money into it.

Ok so I have the laptop on charge, the charging loght is on and the fans are going. I can see the lock screen, but very faintly. The laptop is connected to an external monitor by HDMI butt he monitor is black.

Do I need to connect the monitor to anything else to get it to turn on???

Disconnect the display and the machine should default to the HDMI out. At least, that's what their EliteBooks did last time I tried.

ok so i had a look at the IO more closely and it does have an ethernet port, so I got that hooked up, but then ran into a problem with the web browsing.

That laptop has a internet search safe filter on it, and that flter has 2 modes, one where you can search on the internet, but some things are blocked, and the second mode is completely locked down, no internet searching. I did try to refresh the settings on the safe search filter and change the mode from locked down to the first one, but i can't, so I'm using the laptop as a testing ground. (I did take out the battery before I started trying to take it apart)

I said something about it on the LTT discord, and i posted a screenshot of the error page when i try to search something on the web on that laptop
