I've used PCs since the 90s - NONE of them (EXCEPT for the Dell Inspiron 5559 Notebook) - interrupted my work by displaying random, flashing colours on the screen - and then STOPPED WORKING! Luckily, I could research the problem online using my 12-year old HP Compaq Presario Notebook. Dell (USA) tells you (the customer) that you can contact your local Technical Support for concrete answers.
I approached Dell Technical Support (Australia) through their online 'Chat'. In the message box I wrote:
"NO POST. I pressed the 'Fn' key and 'Power' button - I heard a sharp, melodic double-beep (6 times); then 15 note melody (1 time) followed by 3 strong beeps (3 times); these last 2 beep patterns repeat consecutively. WHAT IS WRONG EXACTLY?"
Over some days, I successfully transmitted this message at least 21 times (that I documented). Each time, the 'Chat' window showed 3 moving dots (to indicate it was going through) - then NOTHING! - the 'Chat' window had simply DISAPPEARED!
[NOTE: I got through the very FIRST time I contacted the company via 'Dell Chat' (Consumer Sales) on March 4,2020. I told the Sales Advisor that I'd been trying to get through on 'Technical Support' Chat with no success and asked if he could transfer me to someone there. He could not accommodate my request and provided a link (that I had already used). I continued to try to make contact with Dell's 'Technical Support'. I had also tried to initiate a chat session with Dell (USA); I was always redirected to the Australian website.]
I thought I did my research before choosing Dell (reading paid editorials). I could not have anticipated that, as a customer, I would be BLOCKED by Dell's Technical Support - thereby preventing me from making crucial enquiries about their product.
I can only now appeal direct to Dell (USA) for help. Given the (above) diagnostic codes and/or beeps, I repeat the question to them: "What is wrong exactly?" I would very much appreciate their answer.
Not that it now matters, my first computer was a Dell Desktop (Pentium).
MARCH 23,2020 UPDATE:
As I await a response from Dell, I should mention that I am indebted to those independent computer technicians who freely post and share their tips. One of these, published October 25,2017, is for the benefit of Dell Inspiron 14 or Dell Inspiron 15 owners called "Dell 3 beep trick for no display problem". The technician advises, "Every model can face this type of problem."
The fix (not a permanent solution) is to press the 'down arrow' + "D" + "W" + "F2" - and the power button also - only removing your finger off the power button. If your laptop processes this code it will show "Preparing Automatic Repair" on the screen; if it does not (after a few tries), to quote (again) from this technician:
"OK. If your laptop shows this type of problem so it's your bad luck because your laptop's motherboard has been Tear down soon and now today's the laptop circuit is being very difficult and cheap and the laptop company has included GPU, CPU, clock together into one piece of i. C so it's very difficult to cure your laptop."
As a newcomer to this page, I'm struck by NOT seeing (public) Company responses from Dell to the 1 Star Reviews. These reviews are 'gifts' - providing Dell with free reports that laser-focus on systemic failures within the company's operations.
As a society, we have the right to be able to rely on our technology. Every customer that chooses Dell believes (intrinsically) that this American company has their best interests at heart.
'Care for the customer' - what happened to it?
April 23,2020 UPDATE Dell - A BBB Accredited Business?
Dell Inc is a "BBB (Better Business Bureau) Accredited Business" (since 04/10/1989) that has been given a rating of 'A+'. (For a list of the many virtues that this accreditation entails see: https://www.bbb.org/us/tx/round-rock/profile/computer-dealers/dell-inc-0825-41453/accreditation-information). Accordingly, "BBB has determined that Dell Inc meets BBB accreditation standards, which include a commitment to make a good faith effort to resolve any consumer complaints."
Dell Inc should be only too aware that '1 Star Reviews' are in fact consumer complaints - albeit expressed publicly. However, Dell has been practicing 'social-distancing' from negative reviews for some time now - which is why these have increased exponentially. For example, at 'bbb.org' (with 2,761 Customer Complaints), Dell Inc has been given a '1Star' rating from an average of 266 Reviews.
This trend is reflected elsewhere, too. For example, at 'Reviews.io', Dell (currently) has 449 reviews with an overall rating of '1.2 Stars'. At 'Resellerratings.com', Dell has 1,716 reviews with an overall score of 1/10. In Australia, at 'ProductReview.com.au', Dell has 479 Reviews with an overall rating of '1.4 Stars'. The Australian 'Trustpilot.com' website has 735 Reviews for Dell with an overall rating of '1.3 Stars'.
Notwithstanding that Dell's overall rating of "3.7 stars" on this website appears to be an anomaly, why hasn't the company responded to the '1 Star Reviews'?
Better Business Bureau advise potential customers:
"When considering complaint information, please take into account the company's size and volume of transactions, and UNDERSTAND THAT THE NATURE OF COMPLAINTS AND A FIRM'S RESPONSES TO THEM ARE OFTEN MORE IMPORTANT THAN THE NUMBER OF COMPLAINTS." [caps added]
The '1 Star' Complaints against Dell are detailed and comprehensive [For example, from: 'bbb.org': 'Ana M' (posted 03/29/2020); from 'Reviews.io': 'Pam' (04/20/2020), 'Michael Smith' (04/20/2020), 'Anonymous' (04/01/2020), 'Anonymous' (03/22/2020), 'Carey Mueller' (03/22/2020) and from 'Resellerratings.com': 'AldertVanN...' (12/14/2019).]
Dell is lauded on 'ifixit.com' for having a full Service Manual to be able to completely disassemble the laptop (to potentially fix it yourself). What good is this when Dell uses 'cheap' parts seemingly designed to break down while the computer is still current and viable (as has been my experience)?
It's been over a month since I first posted my online complaint. I have yet to hear from this "A+" business.
