Plugged in, not charging: Part 2

-
(11) Thought of system restore but had error "System Restore error 0x80070091". Searched online and tried this solution but the last step was unsuccessful because the file already existed.

(12) Meanwhile, rolled back audio driver and the headphone jack always works now!

(13) Re (11) above, just renamed slightly different (added "2" just after "old"). System restore worked but didn't solve the low muffled audio problem.

(14) New problem: when I played Faeria, Overwatch and Atlas Reactor, at least one of these happened:
(a) flickering
(b) discolouration
(c) patches of monocolours
(d) entire screen filled with coloured lines of varying width

Strangely, these didn't happen to Paladins, Small World 2, Guild Wars 2 and Crusader Kings 2.
Was advised by Dell to choose "on" for vertical sync setting in NVIDIA control panel (although I would think the default "use the 3D application setting" is better) and to use the given installer to install some drivers. Didn't work.

(15) After trying out some solution online, finally this works in fixing (14) above: use the compatibility troubleshooter. I was not satisfied though because they were working perfectly fine with Windows 10 before the change of motherboard. Would get Dell engineer to fix this using original setting i.e. not running compatibility feature.

(16) Dell engineer: changed motherboard for the 3rd time. Unsuccessful because it couldn't be charged @@. New problem: CAPS Lock is indicator is permanently lighted up regardless of whether the function was actually switched on or not.

 (17) Flickering was back, despite (15) above, although not as bad as before.

 (18) Dell engineer: changed speaker. Wanted to change motherboard but noticed cable connecting to motherboard is damaged. Laptop cannot be used :( I'm puzzled: why it could be used before the supposed attempt to replace the motherboard? He spoke with Dell at length. Dell would order parts and engineer would come within a week with parts to fix it. List of problems grew once again!

 (19) Dell engineer: replaced the damaged cable (refer to point (18) above), although Dell ordered 6 other parts! @@ I wanted to check audio by playing a video file and/or youtube video but computer hung (not a good sign!). Did ePSA Pre-Boot System Assessment: it was ok. Did a quick sound check. Nope, couldn't hear the 8 different sound that the ePSA supposedly played. Booted to Windows. Played video file, Youtube video and Faeria. Yay! Sound was back to normal.

 (20) All problems, except the original issue, were solved. Engineer advised me to get new battery but I told him that the previous engineer had twice asked Dell to send me quotation for new battery but I received none. He said he would ask them too. Well, we'll see.

William,
New problem: every now and then, laptop can't detect the power adapter i.e. system tells me to plug it in @@. At 7% battery level, it's a problem!

Fell Seal: Arbiter's Mark - character build (Part 1)

-
Here are the character builds for my current run (with the help of Ban): Kyrie Fellblade/Marked Counter: Slow Secondary passives: Execute, Life Font Fellblade itself is a good class because of the various conditions it can inflict and most importantly they can inflict Sleep. Iirc, the only other human class that can do this is Gadgeteer. Their passive Malice increases the chance of landing it by 10%. Fellblade pairs well with Marked because both use ATK and MND in their offensive abilities. Also, Fellblade's abilities are mostly short range whereas Marked has some long range abilities. Execute for more damage. Life Font is for suvivability. Ban opined that with two healers, there's no need for Life Font but I discover that it enables Kyrie to survive just enough for a healer to heal her up, after having received massive damage. Ban advocated for Marked/Fellblade for superior Speed (1.00 vs 0.92) and defense (heavy armor). I resisted this for a long time because I

Fell Seal: Arbiter's Mark - character build (Part 2)

(continue from Part 1 ) Yates Anatomist/Wizard Counter: Cripple Secondary passives: Blessed One, Smart Casting Anatomist is the best healer in game due to the passive Legendary Healer, which also then boost the amount of self-healing by Blessed One. Although Ban thinks Anatomist's Dark spells are sufficient in dealing damage and so he suggests Alchemyst as Yate's secondary class, I choose Wizard for the following reasons: Quite often, demonic creatures have Dark immunity and other creatures have immunity to other elements. So having Dark, Water, Fire, Earth and Thunder spells enable Yates to cast the most suitable spell, especially when the enemies are vulnerable to certain elements. Flexible casting :) Smart Casting is useful so that I don't need to worry much about the positioning of the enemies relative to my other characters when using Mass Healing and the area effect damage spells. As stated in previous post , there "are so many devastating Skill ba

Sudden lower body pain

-
About two weeks ago, my mum developed pain in her pelvic bone, much more on the right side, and squeezing pain in her legs, with occassional spike in pain. She was managing it with paracetamols, 2 tabs three times daily.  Since we didn't know any particular orthopedist in private hospitals (it was only recently that I remember Dr Prashant ), I targeted one at KPJ Penang Specialist Hospital since it's in mainland Penang (instead of on the island). I made appointment for my mum with Dr Joehaimey since he has the earliest suitable date. The moment she walked through his door, he immediately asked her whether the pain from her right side. We were both quite impressed. He was in turn impressed with mum's prepared list of medication that she presented to him on a piece of paper. The key information seems to be the surgery she had back in 2011 to insert titanium plate and screws in her lower spine. He guessed that there's accumalated wear and tear due to aging. So to confirm i
