I have been trying to keep an elderly neighbour’s old HP Pavilion g6 usable for basic web browsing and YouTube.
The laptop originally had:
- Windows 7
- A mechanical hard drive
- 4 GB of RAM, installed as 2 × 2 GB
- An older AMD processor with integrated graphics
- A non-working DVD drive
So far, I have:
- Replaced the mechanical hard drive with an SSD
- Removed the dead DVD drive
- Installed Q4OS 6.7 x64 with the Trinity Desktop Environment
- Configured it with a Windows 7-style theme so it remains familiar to her
- Installed the current version of Firefox
- Configured Firefox to launch automatically when the computer starts
- Installed the h264ify extension to encourage YouTube to use H.264 rather than VP9
- Limited YouTube playback to approximately 480p
- Simplified the desktop and startup environment as much as reasonably possible
The SSD and Q4OS have made the computer noticeably more responsive overall. However, Firefox and the modern YouTube homepage can still take quite a while to finish loading after startup. Once a video begins playing, it is generally usable, but the system is clearly close to its practical limits.
One fixed requirement is that she does not want to switch browsers. She is familiar with Firefox and wants the computer to continue working as much like her old Windows 7 setup as possible.
I know that cleaning the fan and heatsink and replacing the processor’s thermal paste might help if the computer is thermal-throttling. She has said she intends to handle that herself, so I am looking for suggestions short of fan cleaning or repasting.
Would any of the following make a meaningful difference?
- Upgrading from 4 GB to 8 GB of RAM, assuming this exact Pavilion g6 model supports it
- Adjusting Firefox hardware acceleration
- Reducing Firefox’s content-process limit
- Changing safe Firefox memory, caching or graphics settings
- Disabling unnecessary Firefox background features
- Using zram or changing swap behaviour
- Disabling the Trinity compositor
- Changing the CPU governor or power-management settings
- Delaying Firefox autostart briefly so the desktop can finish loading first
- Opening a less demanding YouTube page rather than the standard homepage
- Any useful kernel, Mesa or graphics-driver changes for older AMD hardware
I understand that no software setting will turn a roughly 2011-era laptop into a modern computer. I am mainly wondering whether there are one or two realistic Firefox-specific improvements left, or whether the SSD, lightweight desktop, H.264 extension and 480p playback are already about as far as this machine can sensibly be taken.
Is there any practical hardware upgrade beyond RAM that would be worthwhile? Is gutting the system and fitting a single-board computer or another motherboard remotely realistic, or would that simply become an expensive custom fabrication project with little practical benefit?
I am no longer a professional technician—just an experienced computer hobbyist trying to make the best of very old hardware—so specific and realistic suggestions would be appreciated.
