It's the caps.
If your computer is acting up but has not yet failed you, symptoms of a faulty capacitor include:
- Difficulty turning on your computer, frequently having to hit reset or restart
- Instabilities (hangs, seeing the “Blue Screen of Death,” etc.), especially when the symptoms get progressively more frequent over time
- Memory errors, especially ones that get more frequent with time
- Spontaneous reboots
- In case of on-board video cards, unstable image in some video modes
- Failing to complete the POST (Power-On Self-Test) or rebooting before completion
- Never starting the POST; fans spin but the system appears dead
- Power system malfunctions, fluctuations in system voltage, possibly with an increase in CPU temperature as the core voltage rises
- In the case of Dell Optiplex GX270s, often a “Thermal Event” is brandished in white on a very dark computer display when rebooting.
the link that you provide was a 2010 article about caps produced in 2004.
If you read this link Capacitor plague - Wikipedia, the free encyclopedia
you will read that the 'cap plague' was believed to come to end in 2010.
Most failed caps, not all failed caps, can be identified with a visual inspection.
You will find bulges, and leaky, crusty crap on electrolytic caps.
And on surface mount 'tants' you will find them charred from heat, maybe even a bubble in the plastic, or the white paint which indicates polarity might be burned, missing, or discolored.
If you like taking apart your laptop and feel confident in doing so, then what the hell, why don't you give it a good dusting, and then give it a visual inspection?
IMO,if you don't find a visually defective cap, then your most practical next step is to consider all the caps as good. Why? because it is too much PITA to go around checking every good cap.
Do you have a volt meter? You could measure the voltage of the battery to get a loose sense of whether it is dead.
Just take it off the board, and compare it to the chart in this link.

as you can see, a battery stays pretty strong for hundreds of hours, then eventually its voltage reaches an 'elbow' where the battery will experience failure quite quickly.
For example, in applications like memory backup, the battery will last thousands of hours, then somewhere around 2.6-2.7 volts, it will die with less than an additional 1000 hours.
IMO, a battery that is between 3.2V and 2.8V is good. If it is 2.8-2.6 I would replace it rather than wait for it to fail. If the battery is 2.6-0V then it is already dead which leads me back to a comment that you made...
Yes, I agree that it is possible that a dead battery might cause a delayed start up. I am not sure that it has anything to do with a 'charging' period. Hoever, a dead battery also means no saved bios data. The hanging on the bios screen might actually be the computer having to do additional checks due to the absense of saved bios data.
My wife's got the same notebook. It had a battery problem. I read its common in that brand. I bought a cheap one from Hong Kong over on Ali express.com. Took 2 months to get but her notebook works fine now.
Here is where i bought it.
Wholesale Product Snapshot Product name is [Special Price]New laptop battery for Acer Aspire One A110 A150 ZG5, UM08A31 UM08A71 UM08A72 UM08A73 UM08B74 ,3 cells
I was refering to the cmos battery....another thing altogether...but thanks.
Her notebook was dead on boot similar to yours.... So I thought it could be the same problem.
Hope you can get that fixed. sounds more complicated then my situation.
You can run a notebook with the ac adapter only...the main battery is only for when you don't have a plug in available like at a coffee shop.
OS's get old and need to be rebuilt or trashed depending on your attitude and wallet. Some will outlast others by far and nobody knows why.
You never know when a tiny piece of crud will disturb the transmission of power, i have seen it in a few other ways. Good on ya bud!
Yes I should......I post this in the hope that it might save someone a lot of problems, and even Petros can't find names for me that I haven't called myself..............On second thought maybe he will
