Ever since I started using CentOS, whenever I logged into my CentOS session, I will see a small popup notification in the bottom-right corner of my KDE Plasma Workspace taskbar.
The popup says something like my PC battery capacity is currently 48% (or 49%).
I already long suspected that because whenever I charge my battery, the power seems to drain very fast, usually within an hour or two. The specifications of my notebook can be found here. It's basically a 7-year-old notebook (by the end of this December).
I can also suspect the reason why the battery capacity can deteriorate so much in just 7 years time. I used to leave my PC power on for a prolonged time and usually the power dropped to dangerously low level and simply cut off. This had repeatedly happen over 5-10 times in a duration of approximately 3-5 years. (I wished I were more careful and mindful of taking good care of my PC!)
Ok, some questions for the hardware experts:
1. Now that I have a faulty battery (not sure if a 49%-capacity-battery is considered faulty, but basically let's say it is spoilt), will my daily operations using my laptop be affected?
I am currently using external power source for my notebook and whenever my PC is switched on, the external power source is also on. I suppose this will reduce the burden of my battery, but I am not very sure if this is the right thing to do. What if my battery is "overcharged"?
2. I purchased my laptop for some RM 3000, about 950 USD (assuming 2011 US dollar benchmark, on December 31, 2011, 1 USD = RM 3.17). Now that this PC is 7 years old, and apart from battery issues, it is still looking good. I only use up less than 20-30% of the 500 GB HDD storage space. It also has an optical DVD drive bay which most newer laptop PC doesn't have. Is it wise for me to invest on a new PC just because of my current battery issue?
If say a new laptop is needed, what brand should it be? My current PC/laptop knowledge is very limited:
a. ASUS laptop are notorious for having broken hinges after prolong usage (in fact, the hinge of my current laptop is broken). When I sent my laptop for maintenance (not ASUS-authorized maintenance shop), the person suggests me to save money by leaving the laptop lid opened all the time to "prolong" my laptop's life.)
I do have a keyboard protector so to protect against dust, but elsewhere on the area where I usually place my palm while typing on my laptop, dust can clearly be seen. So far, no effect on PC performance though.
b. Lenovo laptops are "famous" for BIOS exploits, as stated here:
Lenova have a rather poor history with regard to security and if a USB is penetrated then that can propagate into any other PC/laptop/device that USB is plugged into.
3. Please kindly provide any further advice for me to maintain and prolong my current laptop's lifetime.
4. If a new PC is inevitable, please provide advice on basic laptop battery maintenance. Say if I let my PC run to low power and it cuts off its power automatically, will the same issue happen to the new laptop?
Thanks for helping.
p.s. I am very impressed by CentOS being able to figure out my deteriorating laptop's battery capacity. Windows 10 (and Windows 7 which was pre-installed on my laptop) has never shown any message like that. In fact, it shows that the battery level drops from probably 90% to say 80% and then a few further drops in 10-30% in a matter of half an hour or so, which puzzles me a few years back, until I realized that my PC battery is faulty.
I stayed with a faulty battery for years until recently news about power bank explosions while charging surface, I am worried if the same might happen on my old laptop...
