Lenovo IdeaCentre K410: Why won't my computer read any CDs or DVDs?

Mon, 05 Apr 2021 19:19:17 -0700

When I insert a CD or DVD into the CD drive, the computer won't read it and doesn't recognize that I've inserted a disk. The computer is working fine other than that.

Lenovo Desktop: Computer doesn't boot, no POST

Wed, 17 Apr 2024 07:15:29 -0700

Hi! My Thinkcentre desktop does not POST. It stopped working randomly (and in other times, it would start working without any intervention), so I don't know what's causing it.

I tried doing a discharge multiple times, by unplugging any power sources from the PC and holding the power button. And, at least visually, there's no broken component in the motherboard.

By the way, the fan spins and the status indicator lights up, but it stops there, so I can't really use it.

Lenovo Desktop: Thinkcentre M90p - Desktop wont turn on / Powerswitch doesnt work

Sun, 09 Dec 2018 22:27:24 -0700

I own a Thinkcentre M90p - Ive only added a NVIDA quadro 4000 and 16gigs of ram to the stock product.

The computer just wont power on. I replaced the mother board, and the small battery inside the motherboard.

I hear a spark when I plug the power cord in the back of the tower, but when pressing the power button, nothing happens.

Thats my board with nothing plugged,

____________________________________________________________

This is the two pin out of the speaker/beep

_____________________________________________________________

This is the three socket coming out from the PSU

There is a three pin wire coming from the PSU that Im not sure where to plug in, or the 2 socket coming out the speaker/beep speaker.

Im not sure what i can do to get power working. It was working initially, until I plugged the three pin into the power_fan on the mobo next to sata 1. I do not have a volt meter to check if power is coming out the PSU. Is there anything I can do ?

My computer fell down. The desktop is Lenovo core i3. It contained all of my family's most precious pictures. I am very scared. I want all of those files to recover.

Lenovo Desktop: One half of monitor screen is tinted darker(as if for night)

Tue, 04 Apr 2023 08:37:35 -0700

Right down the middle of my (LG) monitor), one side is tinted darker than the other. During the day the tinted side looks more purple, at night it is a tan-ish tint. It is still possible to see graphics and read text on both sides. My desk top computer is a Lenovo. How do I fix this?

It’s 2 long beeps and 3 short beeps, but the computer starts and works just fine. It has been doing it for a couple of weeks, but not every day. It did it again today after about a week without doing it. I just bought this computer in October of 2019.

Thanks for any help.

Lenovo IdeaCentre K410: How do I get my computer to run more quickly?

Thu, 26 Dec 2019 05:09:50 -0700

I haven't had this computer that long but lately it has not been running as quickly as it should. When I open a new program like itunes or Mircosoft it takes at least 5 minutes for it to load. Is there something I can do to make it run faster? I already tried closing other programs first and running antivirus software.

Lenovo ThinkCentre: Post beep code is 3 long, 1 short, no solutions found.

Tue, 19 May 2026 20:53:43 -0700

I got a Lenovo ThinkCentre m920q at a Goodwill for $4. After getting a power adapter for it, and disassembling it for curiousity, the power button light and the red thinkcentre light glowed and fan spun. It then beeps 3 times long, then 1 time short. Thinking the problem may be ram, went to microcenter and got a new sodimm ddr4 8gb. Produces same result. The video is with the new stick of ram. Typing anything on a keyboard when it’s on (f1, f2, delete, enter, etc.) does nothing. Any thoughts?
