My experience, anyway, is that heavily used laptops like mine don't last anywhere forever.
My Lenovo G555 lasted a little more than two years before it died.
And now I've had this HP Pavilion G6 2210-us for three years and six months. I'm on my third battery (luckily they're cheap), and now I'm about to replace the entire keyboard (also cheap).
I bumped up the RAM to the maximum of 8 GB a while ago. No regrets there.
The HP has had one catastrophic drop onto concrete that didn't affect it at all -- except for some nasty abrasions on the plastic case.
The drive it came with was an ample 640 GB in size. I sort of want to rebuild it as a Linux-only computer with a 1 TB drive. I generally have 100 GB of free space, and I'd have even more if I could kill out the Windows 8 instllation that I could never successfully upgrade to 8.1 and hence never even try to get Windows 10. If I don't go SSD (and I can't see doing that on this old laptop), the 1 TB would give me a lot of breathing room.
So the batteries last about a year, and the keyboard lasts 3 years. I'll replace the keyboard and hope the rest of the thing doesn't go south.
Would a more expensive laptop -- this one sold for around -- last longer? I don't think so, but you never know.
While my last key replacement was rocky yet ultimately successful, the results aren't what I'd hoped. And now the space bar is going wonky.
My "new" N key works, but it doesn't have the clicky/bouncy feel of the other keys. I'm not sure if it's the rubber cup or the hingy mechanism, but it is what it is. And it's not great.
I tried new rubber cups that I got from ReplacementLaptopKeys.com, and that didn't help.
The space bar is just generally loose and mushy, and it doesn't work on the ends all that well.
This time I'm just buying a whole new keyboard. What I didn't know is that they're cheap. For this laptop anyway.
I'm not sure if this is the case for all laptop brands, or just HP, but the market is awash with OEM replacement keyboards, and I just bought one for on eBay. Sure I'll have to take the whole damn laptop apart, but it should really have a new lease on life.
Just like on the laptop before this one, if you bang on it and take it enough places, you end up with a busted key.
Where do you get a new one?
HP won't sell you one key.
Enter third-party individual-key sellers like ReplacementLaptopKeys.com, which attempt -- usually very well -- to send you any individual key to replace a broken one.
So I noticed a BIOS option to turn the CPU fan off on my HP Pavilion g6-2210us. I tried it.
After invoking this in the BIOS, the fan didn't run all the time. It ran about half or more of the time. And the bottom of the laptop was appreciably hotter.
So I went back into the BIOS and turned the fan back to "always on."
Now the laptop runs cooler.
The fan isn't so loud that it's a problem, and it does have variable speed, so having it cycle off and on is more noticeable than just having it on all the time.
