@allquicatic Sorta both. By choice, since I wanted portability, but stuck with the crappy wired ones because the bluetooth ones that actually seal the ear canal that I have likely have dead batteries, since I haven't used them in a long time.

Best I got so far. That 280Hz frequency seems to ring quite a bit on these.

Q: HP Envy 17 3D 2199 el is incredibly slow

Back in 2012 I bought this laptop which has the following specs: Intel Core i7 - 2630QM @ 2.0 Ghz 8 GB DDR3 RAM AMD Radeon HD 6800M / Intel HD 3000 I even bought a Sandisk SSD 128GB (with windows 10 home installed on it) that I have installed along with the 1TB HDD (that I use for Data) The ...

Guitar Shoe Dave

sounds like swapping to me

get more memory

Daniele C

how can 8gb not be enough even while only using file Explorer?

Ben Richards

Couldn't be swapping unless most of that RAM is bad and Windows only sees like 2 GB or something

Daniele C

on the computer properties <i can see all 8GB of RAM

bwDraco

18:39

> it takes minutes even to load Edge, It is always hot and with fans spinning at max speed.

Something hogging the processor?

djsmiley2k

@DanieleC win 10, 2012?

bwDraco

This does not sound like disk thrashing.

djsmiley2k

souinds like bad drivers, cpu trottling

Ben Richards

All I can think of with the combination of slowness, lack of CPU and disk activity, and no swapping, is a combination of the processor being very underclocked + bad graphics drivers causing you to always use the discrete graphics chip rather than the cooler and less power hungry Intel HD 3000 graphics.

Guitar Shoe Dave

is the unit making crunching noises?

bwDraco

18:42

A better question to ask is "is the disk activity light constantly lit?"

Ben Richards

Though actually, it could just be bad grpahics drivers so it's only using the hotter AMD graphics chip, and if the cooling in the laptop is poor enough, it may be throttling the CPU and memory down significantly to prevent damage.

Daniele C

Please have a look at the question again that I have updated with images

Ben Richards

I would probably check that the airflow is good, reapply the thermal paste on the heatsinks, and then see if it runs as hot and slow. A faster check would be to see if you can force it to use the Intel graphics (if it is indeed just using the AMD graphics chip)

I'll post as an answer

Daniele C

@bwDraco Yes the hdd light is Always lit

bwDraco

Okay, so this is disk thrashing. Any idea what's causing it?

Daniele C

18:46

what exactly is disk thrashing?

bwDraco

Odd. I see little disk activity on Task Manager.

Go back to the Processes tab and sort by Disk.

Ben Richards

Disk thrashing would occur if it swaps heavily. Basically that means it's reading and writing to the chip at an extremely high rate, possibly saturating the SATA link.

Daniele C

allquicatic

look in Resource Monitor

under disk or CPU

Daniele C

here is the task manager sorted by disk

allquicatic

18:51

is it windows 32-bit or 64-bit?

I glean it's probably 64-bit from the "(32-bit)" in Task Mgr

Ben Richards

Probably 64-bit since it sees all 8 GB of RAM

Daniele C

64 bit

Ben Richards

I'm pretty sure while there's probably a 32-bit Windows 10, it might be very difficult to get your hands on, relative to 64-bit.

djsmiley2k

Cortina!!! <waves fist at skiy>

Ben Richards

I posted an answer with my suggestion. It may or may not be disk thrashing.

allquicatic

18:53

hmm, could be a defective SSD

or, if this is a very low-end SSD, it might be bottlenecking -- low-end Sandisks don't have a DRAM write cache

Ben Richards

Is there anything on the HDD? You did install on the SSD, right? Old laptop HDDs are very slow in my experience anyway, no matter what chipset you have.

Daniele C

I don't think it's the SSD since it was doing the same things before

djsmiley2k

4 yr old -- failuing ssd?

kerbalspacecat

@Bob Nope :-|

Daniele C

the SSD is new on the HDD I only keep my data

djsmiley2k

18:54

'before' what?

Daniele C

OS is on the SSD

Ben Richards

I doubt it. Unless there's data loss, SSDs tend to just stop working, I'd think.

Daniele C

before I bought an SSD an put it along side it

allquicatic

hmm... would be interested to see how it performs on an Ubuntu live CD

could use a disk benchmark from Ubuntu to see if the controller is operating in a very slow mode or if the disk subsystem is just very slow

and can check dmesg for ATA transfer failures, etc

...wait

this is Sandy; could it be a failing SATA controller on the chipset?

the thing they recalled?

Ben Richards

Unless it's a slow SATA connection, which would throttle any fast SSD or other HDD, I'm standing by heat + poor cooling (and possibly shoddy thermal paste quality) = heavily throttled CPU and RAM.

Can you see if the CPU is running at speed?

allquicatic

18:57

@BenRichards the task mgr screenshot shows the CPU running at 0.82 GHz and 1% utilization

Ben Richards

It can be throttled while still at 1% utilization. Is 0.82 GHz fast for this chip? I don't know, myself.

allquicatic

@BenRichards 0.82 GHz on a Sandy Bridge-HM is definitely fast enough to start up a browser in less than "minutes"

Ben Richards

Ok

Daniele C

it is a 2 GHz chip so it is pretty average i think

allquicatic

like I said, eliminate the driver factor first; put Ubuntu 16.04 64-bit on a thumb drive and boot it up

from there, run some disk I/O benchmarks against your SSD and HDD

Daniele C

18:59

ok I can do that

allquicatic

if they're not running well from Ubuntu, you know you have a hardware problem

Daniele C

which benchmarks should I use to check for this problems?

Ben Richards

I suspect the driver is the reason the fans are high and it runs hot. It uses switchable graphics and it might just be using the discreet GPU all the time.

If it's not throttled due to heat, though, then the speed might be entirely unrelated to that.

Daniele C

It could be, how do I force it to use the intel graphics instead?

Ben Richards

You'd need working Intel drivers for Windows 10 to do that.

Daniele C

19:01

aren't they already installed?

Ben Richards

It's a 4 year old laptop, the drivers may not work properly on Windows 10 if they were made for Windows 7 or 8.

Daniele C

it was using to have the same problems even on Windows 7 though

Ben Richards

Generic drivers might make it just use the discreet graphics chip, or just the Intel chip. I don't know. I don't have lots of experience here.

I think you can check which GPU it's using by checking what the graphics adapter is reported as in display properties.

If it was doing the same in Windows 7, and I'm presuming the drivers worked fine there, then it running hot might just mean lots of dust or bad thermal paste application/quality or the like.

allquicatic

just look in driver manager and see what's there in terms of display adapters

Ben Richards

Check your disk I/O though, that's a good avenue for the slowness.

Sounds like you have two separate issues--slow performance and it's running hot.

allquicatic

19:04

@BenRichards yeah, but that's incongruous with the perf issue; running off discrete graphics should be faster than running off the IGP

Daniele C

it's running whit intel graphics 3000

allquicatic

the running hot could be because you have it set to High Performance profile :P but then you wouldn't be seeing 0.82 GHz out of 2.00, hmm...

Ben Richards

@allquicatic It shouldn't matter when launching a browser. The only performance increase you may see in regular Windows operation is less choppy animations (like when dragging windows around)

Daniele C

I have it set to balanced profile

allquicatic

I'm starting to suspect the possibility of a rootkit that's making you mine bitcoin or participate in a botnet (one that cleverly hides itself from Windows' performance counters) :/

again, running Ubuntu should eliminate that as a potential factor

Daniele C

19:06

what software should I use to check the disks on ubutnu?

Ben Richards

Also a possibility. Rootkits are sneaky like that.

allquicatic

well the built-in Disks application can do disk benchmarks, I think

you want to be careful because it may want to wipe the HDD to do a benchmark

I'll poke around and see if there's something better

Daniele C

thanks

Ben Richards

I haven't done disk I/O benchmarking in a very long time.

allquicatic

OH

Daniele C

19:08

i don't think its a rootkit cause I bought a brand new SSD I installed a fresh copy of Windows 10 on

allquicatic

before you reboot into Ubuntu, from Windows, run crystal disk mark: crystalmark.info/software/CrystalDiskMark/index-e.html

if at least the SSD's performance is what you expect (should be at least more than 250 MB/s read and write for sequential), it's probably not a disk issue

Ben Richards

Rootkits can live in firmware, can't they? Wasn't there something like that going around?

allquicatic

@BenRichards yes, they can live in either the BIOS/UEFI firmware or the NIC firmware even :P

theoretically the GPU firmware if it's writable

ooooor....

if she didn't wipe her old files from the HDD when reinstalling Windows...

maybe she opened a document or ran an application from the HDD that transmitted the rootkit into her present install

Ben Richards

Yeah. Lenovo was caught basically with their own rootkit in some of their PCs that got installed even after a complete wipe because the Windows install allows loading of drivers from UEFI, which has a legitimate purpose for automatically loading drivers if needed.

But that can be exploited.

zdnet.com/article/…

allquicatic

I can't imagine criminals are sophisticated enough to write multi-platform firmware-resident rootkits though, so hopefully "the Ubuntu test" should yield good performance and low fan speeds and we can move forward from there

(APTs are sophisticated enough but we presume our friend here is not on the NSA's shortlist)

Ben Richards

19:12

@allquicatic Yeah, I'm just saying, it's one way if it was a rootkit that it could've survived a SSD upgrade and a clean reinstall.

allquicatic

@BenRichards it's far more likely they just ran an .exe from the HDD after installing clean on the SSD but not wiping the HDD

Ben Richards

Or it was an infected USB drive, yeah.

allquicatic

any self-respecting rootkit would mangle as many .exes on the system as possible to guarantee its spread

Ben Richards

Anyways...

Daniele C

ok I am running the disk benchmark

allquicatic

19:13

probably also want to verify the SMART status of the disks and make sure they're using AHCI instead of some old horrible SATA protocol

like back in the IDE days when sometimes the IDE controller would fault you back to PIO mode

limited to some ridiculously slow transfer rate

Ben Richards

A 2012 laptop shouldn't be doing that :P

allquicatic

unless it has a problem

Daniele C

the benchmark on Windows is showing 314 mb/s read

allquicatic

pcmag.com/article2/0,2817,2379241,00.asp

Daniele C

and 190 write

allquicatic

19:15

@DanieleC that's a little slow for an SSD, but within reasonable expectations for a budget 128 GB SSD

that's about 2 to 3 times faster than a typical hard drive

Daniele C

its a Sandisk ultra II SSD

allquicatic

news.softpedia.com/news/…

@DanieleC yeah, you should be safe from the bug; but I'm a little concerned that it's in "RAID mode" instead of AHCI

Daniele C

I should chenk in the bios maybe

allquicatic

you can't benefit from Native Command Queuing unless you're in AHCI mode

@DanieleC yeah; if it says "IDE" or "RAID" for the SATA controller mode, try changing it to AHCI

hopefully Windows 10 is smart enough to still be able to boot your system :)

Daniele C

ok I'll try

and I will let u know

thanks a lot

Boris_yo

@DavidPostill Like the genre?

Ben Richards

I've switched between AHCI and RAID mode before. I only had to make sure I had RAID drivers installed (or AHCI drivers, going the other way) otherwise it couldn't find Windows and would report no bootable OS found.

oh, there was also a totally unrelated debacle with Ubuntu a few years ago, involving HDDs, where a critical piece of configuration in a Debian package, setting the HDD spin-down time, was set to 0 seconds -- so after 0 seconds of inactivity the disk would attempt to spin down, and then would immediately come awake again

as you can imagine, this wore out the mechanism for putting the head on and off the platters very quickly and killed drives

kerbalspacecat

@kerbalspacecat does 3d crosspoint need its own new storage I/O protocol though?

kerbalspacecat

@allquicatic Maybe?

allquicatic

19:42

I think conventional NVMe or even AHCI should work in principle (though AHCI would not take advantage of its raw speed)

Ben Richards

I got (typed, so could be wrong, but yeah) PCI\VEN144D&DEV_A802&SUBSYS_A801144D&REV01\4&25BACB6&0&00E0

kerbalspacecat

I doubt you can use it as persistent storage in any old DDR4 slot if the EFI treats it as normal RAM

allquicatic

crosspoint is being used as persistent storage so it will be attached to the I/O subsys, not installed as system RAM

Ben Richards

Says it's using the "Surface NVM Express Controller"

allquicatic

they might release a product later on that acts as main memory

Have they backtracked?

allquicatic

19:44

@kerbalspacecat oh ok, that's newer info than what I was working off of

the initial speculation when it was announced was 100% "this is the next SSD"

Daniele C

Is there something else I could try?

allquicatic

@DanieleC I still think an overall system usability test, benchmark / SMART self-test in Ubuntu on a thumb drive would go a long way

Daniele C

Ok I Will do it.

allquicatic

if we can get good I/O perf out of your disks and good system usability (web browsing, etc) on Ubuntu, we know something Windows-related (driver? rootkit? something...) is bad

keeping in mind a USB thumb drive as your system volume will be a bit slower than an HDD, but if it ends up being faster for usability than running off your SSD, you know the problem lies in Windows somewhere

kerbalspacecat

@allquicatic To be fair, the article is nearly a year old, and the recent "demo" units of Intel 3dXPoint have been PCIe Optane drives

Also: theregister.co.uk/2016/08/16/…

> In the week of Intel's Developer Forum we have heard its Optane XPoint SSDs and DIMMs may be delayed.

We are hearing that the first version of XPoint chips can only be used for SSDs. A second, more developed version is needed to make XPoint for DIMMs. That means XPoint DIMMs may not appear until 2018, which would give competing non-volatile DIMMs more time within which to establish themselves. If true, this means Diablo and Netlist get more breathing space.

ahh

is the new mobo chipset being released going to support both existing CPUs and Zen?

kerbalspacecat

> The AMD AM4 platform provides next gen I/O and peripheral support including PCIe Gen 3, USB 3.1 Gen 2, NVMe, and SATA Express. It also offers higher power efficiency than previous AMD desktop platforms (up to 70 per cent power used compared to AM3+). AMD says that the new HP and Lenovo designs featuring AM4 show the ecosystem's readiness for the upcoming high performance 'Summit Ridge' processors, based upon 'Zen' cores. AMD has a "commitment to support AM4 for years to come".

Last time I heard AMD commit to support my socket for "years to come" they ditched it less than one full generation later.

@allquicatic Yes

@kerbalspacecat What socket? AM3 chips will work in AM2 and AM2+ boards.

Daniele C

@allquicatic I will! thanks a lot again!

Part of the reason behind AM4 is so AMD can amalgamate everything into one socket, for all their processors. Both the high-end ones and the low-end APUs are going to become AM4

bwDraco

Mar 28 at 2:27, by bwDraco

As noted before, all Zen desktop AMD processors will use Socket AM4. No more confusion with three different sockets (AM3+, FM2+, AM1) as before.

Translation: The moment you realized that you should have upgraded your aol dialup internet from AOL ultra version to the AOL titanium version.

That is how you database.

Dammit I need to re-learn how to database

Or rather how to architect a database from scratch

allquicatic

@kerbalspacecat for what purpose?

Guitar Shoe Dave

I got a complaint earlier saying a report was taking too long to run. And I gave them that response.

@allquicatic mobile network signal readings

The service I used to use is getting slow and unreliable and takes about one minute per 1000 data points to show/filter it on a map. I have about 50,000 data points per network now :-/

So basically going to build my own Web service (and eventually mobile app) to visualise the data

@GuitarShoeDave Do people still use "Codd's Rules" these days? (you can tell when I last did any serious database design ...)

!!wiki Codd's Rules

ChatBot John Cavil

Codd's 12 rules

Codd's twelve rules are a set of thirteen rules (numbered zero to twelve) proposed by Edgar F. Codd, a pioneer of the relational model for databases, designed to define what is required from a database management system in order for it to be considered relational, i.e., a relational database management system (RDBMS). They are sometimes jokingly referred to as "Codd's Twelve Commandments". == Details == Codd produced these rules as part of a personal campaign to prevent the vision of the original relational database from being diluted, as database vendors scrambled in the early 1980s to repackage...

DavidPostill

@CanadianLuke Yeah, I know what they are. My questions was do folks still use then when designing databases? Or have they been superseded by some newer wisdom?

allquicatic

@DavidPostill rules of normalization, sure, but I've never heard of them used as Codd's rules

and "over-normalizing" can be bad

Canadian Luke

@DavidPostill I had no idea what it was... I just know of normalization... And only 3 levels of it

allquicatic

also they don't apply to NoSQL databases generally

DavidPostill

21:02

@allquicatic Why not?

allquicatic

@DavidPostill because NoSQL databases aren't relational; they're usually key-value or object-based

DavidPostill

@CanadianLuke Ah. I learnt them 30 years ago or something.

allquicatic

key-value is just a persistent hashmap, and the relationship between objects is defined by the object graph

rules about an RDBMS don't map well onto either of those paradigms

DavidPostill

@allquicatic Gotcha.

allquicatic

> Rule 1: The information rule:

All information in a relational data base is represented explicitly at the logical level and in exactly one way — by values in tables.

yeah, k:v and object databases fail that rule right off the bat, by design, intentionally

and somehow they manage to work in production software all around the world

Grrr. Converting 3700 files with
for file in *.gif ; do echo processing `basename $file .gif` ; convert steamer.gif `basename $file .gif`.jpg ; done;

Downlaod them... all the same. Whoops

steamer.gif -> $file

Ben N

You can use PowerShell!

Hennes

We can?

Ben N

You can

Hennes

I just uploaded them all to a BSD host, run imageMagic, and now downlaod them back

I guess it is a 'people use the tools they know' thing.

Ben N

It can run any .NET assembly, like System.Drawing, which has a thing that can convert images

Add-Type -AssemblyName System.Drawing
dir *.gif | % {
  [System.Drawing.Bitmap]::FromFile($_.Name).Save($_.Name + '.jpg', 'jpeg')
}

@BenN nice little script

Ben N

Thanks! PowerShell is pretty great

allquicatic

I wrote a fairly simple Excel spreadsheet manipulation script in VBScript, PowerShell and C# a few years back for work

the PowerShell version ended up being the most painful because of the automatic loop unrolling and figuring out how to make it not do that

the C# was the easiest

Ben N

If I understand correctly, it shouldn't do that unless you explicitly do something to the collection that's not applicable to the collection as a whole

e.g. if you tried it in a PS version less than v3, it would fail, like (dir).Name

Hennes

This got a bit out of hand:

0) Browse a webcomic (alexcartoon), starting from the first comic>
1) Failing to find a first button, image the repagination plugin to get all comic on one page (3755 images plus headers etc)>
2) Save do disk
3) Play with the 26MB .html file, decide that you might as well use the photoviewer>
4) Find out that windows photoviever does not zoom. At least not with these gifs. Worked when converted to PNG, JPEG etc, just not at gif
5) Upload to a BSD host and convert to JPG

A never ending story.

Q: Lenovo IdeaPad Flex 14 leaking sticky gel

Our Lenovo laptop, which was manufactured on 2013/08/25, started leaking a clear gel from the lower right hand corner of the screen. Other than being messy, it does not appear to have any effect on the performance of the device. Any suggestion on what is causing this and if so what can be done ...

That's new.

that's the most powershell I ever wrote and it didn't even get used :( vbscript got used instead
