Re: Startup time issue - T420s

2011-11-14, 19:46 PM

That's what i thought. So the problem remains that even after disabling all other drives (except my SSD) from the bios boot priority list, my computer still spends an extra 45 secondsto boot by running the CD drive when I power on.  If I remove the CD before booting up, then problem solved. But there must be a better way to resolve this issue in bios. Any ideas why the boot priority list seems to have no effect?

Something still seems very very fishy if you're taking 50 seconds to boot on an Intel SSD.

Are you on the latest BIOS?

W520: 2960XM, Q2000M @ 1091/1380, 32GB RAM, 500GB&750GB HDD & 500GB SSD, FHD&MB168B+
X61T: L7500, 4GB RAM, 500GB HDD, XGA screen, Ultrabase
W550s: 5600U, K620M at 1164/1281, 16GB RAM, 512GB SSD, 3K touchscreen
X200s: SL9400, 6GB RAM, 64GB SD card, WXGA+ screen

Are you sure that there are 2 boot priority lists in the legacy bios? I only see one list. Is there an advanced feature to switch between the AC and battery boot order lists?


My bad.

 

My apology for confusing the normal boot list and the network boot list.

Re: Startup time issue - T420s

I just downloaded the new T420s bios and my boot time without a CD in the drive is 40 seconds and with a cd it is 1:45 from power-on to desktop.

 

I spoke with a Lenovo tech on the phone and he agreed that the bios was saving the correct boot order (with my SSD at the top of the list) but seemed to be ignoring it and still looking to boot from the optical drive first.

 

Does anyone have any other ideas for my to try? I haven't even put much software on the laptop yet as it's only a few months old.

Is the setting "Boot order lock" checked?

 

 

Do you have a CD inside the drive? If yes, could you try inserting another CD, lets say a Music CD and see if the speed is the same.

Thanks for the good ideas.

I have boot order lock set to disabled. Is that correct?

I tried to use a regular DVD movie in the drive instead of a game. Here are my results from power on to desktop.

No disc in drive: 40 seconds

DVD movie in drive: 59 seconds

Game disc in drive: 1 minute 43 seconds.

These times are consistent depending what I have in the drive. Do you think this is normal for my t420s with i7, and lightly used 320 series ssd?

so i still say there is something wrong with the CD disc itself, since when you put in another media (DVD movie) you get better bootup speed. with Intel 320 the bootup speed I presume is normal.

 

So as in my earlier suggestion, use the burning software included with the lenovo, create an ISO image of the game disc and store it on the SSD. Then use magicISO and mount the image. During gameplay you definitely would get better speed than reading it from the DVD drive anyway.

I still don't understand why the boot priority list doesn't seem to have an effect. If I remove my DVD drive ( and all other drives except for my SSD) in the bios than why does the DVD drive still spin up (and delay my boot time) when I power up. If its not in the boot list than it shouldn't spin the disk at all, right?

First it could be lenovo firmware problem, or error in the operating system. The boot list may be executed correctly, something else is in play here. If you are handy with a screwdriver, plug out the HDD/SDD, and reboot with the disc inside, you should see the bootup process trying to go in the correct order....

 

My guess is that the motherboard/bootup/operating system is trying to identify the disk, it may not be the booting process.

 

When the motherboard startup, it will try to detect all devices connected to it. Imagine if it doesn't and you set the first bootup device as DVD drive and it just happily bypass it. During the detection it just want to know if this device is alive, what it is and then probably check the bios / operating system what was the settings to do with that device.

 

You can try this experiement, without the game disc inside, after you bootup, insert the disc and does it takes a while for the window 7 to detect it's presence, name, etc. If you hear a lot of whizzing sound, fast and stopping, clicking, then the drive probably is having a hard time reading the disc. Put in another disc, and see the result.

 

So when you boot up with the disc inside the drive, AFTER the detection, the operating system may have taken over and ask the drive, hey, whats your name. Same thing it does with th harddisk, SDD etc...so that it will show up in the desktop. If the disc is hard to read, then the drive may be just communicating with the operating system and hence slowing it down. After some time, the operating system gives up and continue on it's way.

 

It could also be the firmware on the drive itself, having some smart function and trying to interrupt the operating system and have it's own way...
