RE: Del Inspiron 5559 modum slow

No problems found on up on Troubleshooter search.

I'm a fan of TaskManager and routinely check for anything eating space. The biggest offenders appear to be Dell help and other Dell services. Have turned off, disabled or set to manual most of these.

Seems to help a little.

Thank you

I see DELL-Akshatha M and Dell - Brad L reply to your questions in Disk Drive and Software & Operating Systems. Hopefully your computer works normally in the very near future. Thanks for the update.

RE: Del Inspiron 5559 modum slow

It continues.

Now I get pop ups saying I'm disconnected from the internet and will connect soon.

I'm connected Ethernet and when I check all systems are ok except for this computer.

And I consistently get dead pages saying my computer is making a Network change?

I have spend so much time troubleshooting that I can't do my actual work.

RE: Del Inspiron 5559 modum slow

All day this computer has been falling off the internet. I check my other devices and none of them show any problem with the internet. This one is connected Ethernet most of the time. Even when it is WiFi it is producing error messages that say:"There is no internet connection" or "This site can'

t be reached, it too to long to respond". Then a reboot and I can get back online and back to the site with no problem - for about 15 minutes.

I have one browser window open. ONly one device on the internet at a time. My Task Manager is showing 8% CPU, 40% Memory and 8% disk, so it can't be overload.

Grrr...

RE: Del Inspiron 5559 modum slow

Hi Sumni - I also have a Dell Inspiron 15 5559, which I believe is very similar to yours. (Core i7, 12GB, 1TB 5400RPM HDD)

I immediately noticed the slowness you are talking about and I had other problems with the laptop when I first tried it: the SD card slot wasn't working, the brightness of the LCD screen would not adjust, and hard drive access seemed to be very slow for such a new, advanced laptop.

I know from experience that one MUST make sure BIOS and drivers are updated. So here's what I found:

1) There is a BIOS update needed for the machine. It is only one version later, but it seemed to help.

2) There are four drivers that need to be updated. I used www.dell.com/support, logged in with the service tag and chose "look for driver updates". There are four important driver updates for the machine that you need to download and install from the support website, they make the chipset work better.

3) My hard drive is very slow. I got the Toshiba MQ01ABD100.  It has ONLY AN 8 MB CACHE and is a SATA 3Gb/sec drive! (Your laptop can use a 6Gb/sec SATA drive)

Drives like this usually have 64MB or 128MB cache, so this drive is going to have VERY poor performance. (If you look it up on Newegg, it's only $49.99!)  Worse yet, the slow speed doesn't show up well on the Perf Meter application - you just get a "% number".

4) My Inspiron has 12GB in an 8GB and a 4GB SODIMM. That means the Skylake CPU system cannot read the RAM in interleaved mode, which is a much faster way to read and write to RAM.

What this all means is that our fantastic, superb new laptops are being dragged down by old BIOS, old drivers, SLOW hard drive and sub-optional RAM configuration. The Dell support folks in this forum thread are doing a great job of trying to help you, but they can't really say these things. I'm just a customer (and long-time IT system admin), so I can call it as I see it.

The value proposition for the Inspiron 15 Model 5559 is very good: this is a name brand, quality product. I don't wish to send mine back to Dell or otherwise discard it: I plan to fix the slow points and see what happens.

My plan is to exchange the 1TB Toshiba drive for a 512GB SSD and to exchange the 4GB DIMM for the correct 8GB DIMM. Then I'll install Linux and see how well things work. If I have time, I'll benchmark before-and-after.

I am planning this work sometime in the next three or four days. Would you like me to report my results back to this forum thread?

RE: Del Inspiron 5559 modum slow

One more thing Sumni: I have worked with Dell products for a very long time and I have a great deal of faith in Dell. Dell does not make hard drives, so I don't blame the laptop for a slow hard drive. I bought my Inspiron after a great deal of thought and I plan to use it for years to come, it just needs to run a little faster to do the job.

I have also used Dell for years, however, just because they don't make their hard drives they are responsible for the equipment they build and sell. So if I find that the product that I purchased is not working properly, it is still their responsibility to make it right.

The Sleeping Giant Has Awakened!

SSD installation (Samsung EVO 850 512GB) and 8GB Dell RAM (now 16GB total) are complete and Linux MINT has installed in mere minutes. Everything in Linux MINT (a Debian/Ubuntu fork) works: wireless, ethernet, keyboard backlight, functions, etc. The full potential of the Inspiron 15 5559 has been unleashed: it is now the fastest computer I have ever owned, to-date.

RE: Del Inspiron 5559 modum slow

groceryboyjr, I would really be interested in hearing what happened after your upgrades. I have a slow, wifi-dropping 5559 as well.

Thanks!
