Solved motherboard, or BIOS?

[Richard58]

Hello, Wndows 7 Home, updated to Windows 10 recently, laptop model HP G62-149WM. When shutting down the computer, the clock and date in the right lower corner did not keep up correctly, I was told it was probably the 2032 CMOS battery. I took the laptop apart, installed a new battery. The motherboard was sitting on the kitchen counter when it got knocked to the vinyl floor below. I saw no broken parts other than a USB cable holder piece, it's the part you lift up to remove the cable. I reinstalled everything. Now, when I start it, I see "HP" logo, then Windows logo, then the Windows music sound, then the screen gets slightly less black -- and that's it. I've started it, clicked "delete" rapidly, same results. I tried "F10" also. Is there something special I have to do to after installing that battery,? -- could I have damaged the motherboard with it falling to the ground.? I do have a Windows 7 repair disk and reload disks. I live rural and my local repair place isn't taking repair jobs thanks to Covid. Thanks for any help.

then Windows logo, then the Windows music sound, then the screen gets slightly less black -- and that's it.

Bios has handed control to windows. Then something goes wrong.

Hard to ell. Does the installation/recovery media load up ok?

 

[Richard58]

I don't know. I haven't tried that yet in case that wasn't the right thing to do. I'm not that knowledgeable about computers so I didn't want to do something stupid and regret it. I've got the laptop apart right now looking for any issue. Do you think I should try the repair disk after I put it back together? The repair disk is for Windows 7 -- which I'm happy to go back to anyway (I did an internet upgrade to Windows 10 a couple of months ago).

if the install/repair media loads, then the issue could be a problem with the installed os. Though dropping laptops can also damage the hard disk or the connections. This is only to check that a bootable os runs ok in ram.

On a separate note:

If you want to try and reinstall/repair win10, you need win10 media.

If you want to reinstall/repair win7, you need win7 media.

 

[Richard58]

I'm ok with reloading Windows 7. As for dropping -- it was just the motherboard and memory boards (if I have the right term). The hard disk was not attached, or the CD player. I don't remember if the CMOS battery was installed when it fell off the counter.

 

[Richard58]

I put the pc back together, no change. I loaded the repair disk into the cd drive and then turned off the power, then shut the cd drive. Then I turned on the pc -- no change, did not hear any sound of the disk drive. So with the power on, I opened the cd drive and then closed it, it sounded like the cd was spinning but lasted a few seconds before stopping.. Nothing new happened, no change. Is it something with the BIOS, or maybe I damaged the motherboard when it fell.?

 

[SIW2]

Probably damaged.

If you are not desperately skint, probably easiest to order a replacement mobo. Can often be had second hand online. Likely cheaper than attempting repair.

 

[SIW2]

I just had a very quick glance on ebay and they seem to be mostly faulty mobos beimng sold for scavenging parts.

Unless you are confident fiddling about, you might need to wait till your repair shop can take a look.

I assume the cpu and heatsink were attached when it hit the ground? Hard to tell what the issue is from a distance.

 

[Richard58]

I don't know how to recognize the "cpu" and after looking up a "heatsink", it appears to be the fan, -- and yes, the fan was still attached. If I order another motherboard, will it come with those on, or do I have to transfer a bunch of parts. I could do a simple swap of motherboards, but if I have to transfer small parts, that's probably going to be out of my league. Looking on the internet, mobo's seem to run $70 - $125 for new, but it looks like I'd have to transfer parts (and the older I get, the worse my vision is). But getting the exact right one might be difficult. What's your thoughts --and thank you for this help.

 

[SIW2]

do I have to transfer a bunch of parts

yes. Best to get a repair shop to have alook. It might be something simple , can't tell without looking at it.

But if it is going to be an expensive repair, maybe think about getting a new machine.

Thanks for the link, the job didn't look all that bad. Maybe I'll just start look for a replacement board and go from there. Thanks for the help and the link. I'll take it from here. Thanks again.

If you are going to attempt that, you need some isopropyl alcohol for cleaning the tof the cpu and heatsink, then some thermal paste - in the video you can see he puts a little bead of tp on the cpu before attaching the heatsink.

[Richard58]

Yes, thanks, I saw that information from the video and it's comments. I also remember that my unit used to get hot a lot. I often blew it out, and when I opened it up, it wasn't full of dust and debris. Maybe something else was wrong. I admit I would leave it on all day with the electrical plugged in. Maybe I need a new heatsink assembly too. Or maybe I just need to break down and buy a new unit -- my desktop unit is Windows 7 and I liked it with both of them having the same system. And now that I'm retired, I don't need either one for work as I used to use them. I may travel 70 miles to get to a repair shop and have them look at it. Thanks for the help, nice links.

 

[Richard58]

So, I did a little dancing on the internet with my desktop unit and saw an issue similar to mine. One of the commenters on YouTube mentioned to pull the memory boards and reinstall them. They had seen that solve the issue. So I pulled both of them and put each one back in individually -- and in both cases, the computer started up. So I put both back in, and the computer is working.
I went on the internet, figured out how to reset and save the bios -- everything seems to be working.
