Lenovo Thinkpad T430: 2100: Detection error on HDD0 (Main HDD) - problem with motherboard

Sun, 25 May 2025 11:29:29 -0700

Hi everyone,

Lately I have been getting this problem when booting the computer: "2100: Detection error on HDD0 (Main HDD). Press Esc to continue". I used to press Esc and then the computer would boot normally, but the other day when I booted the laptop I just got a black screen and nothing reacting (even if the power button had light, but it would not even switch off). As I did not know what to do, I took the laptop to a technician.

He was trying another hard drive in the laptop to see whether it was a problem with my HDD or with the connector of the motherboard and concluded that the problem was the motherboard and it had to be changed. Basically, the connector is a bit loose, so the HDD moves a bit, what causes the connection problem. As it is quite a lot of money, I decided to take the laptop home and try to figure out a solution.

The solution that I have found is to place two cotton pads from the ones used to remove make up below the HDD, then installing the HDD and place another cotton pad in between the HDD and the sponge that is inside the case. With the added pressure of the pads, the HDD does not move and everything works fine so far. However, I feel that this solution is not the best one. So, I was wondering whether you have better ideas.

Is there any other solution that you can think of so the HDD does not move or to fix the connector without changing the motherboard?

Can you suggest other materials that may be better than a cotton pad?

Cheers!

Lenovo ThinkPad 410: Laptop Completely Dead Won't Power On At All

Sun, 20 Apr 2025 00:06:02 -0700

I’m in possession of a Lenovo ThinkPad T-410 that I got from my old job of about 4 years ago. It USED to power on and work just fine. Now?…even with the power adapter plugged into it, it just does nothing. No power, no lights whatsoever. What could be the problem? I already tried the “Remove-Battery-And-Hold-Down-Power-Button” routine with negative results. Is there someplace I can ship it to have it looked at? I mean its not a critical issue, but its got sentimental value to me, and I wouldn’t mind giving it a second life as a backup.

Lenovo ThinkPad T510: Upgrade LCD screen resolution in Lenovo ThinkPad T510?

Mon, 08 Apr 2024 15:08:35 -0700

I have a thinkpad t510 4313 CTO running on a 1600x900(HD+) resolution. Since the screen cracked, I want to replace the LCD screen from HD+ to full HD(1920x1080). I have seen warnings in few forums that some times cable needs to be changed or upgraded screen might look fuzzy. Please tell me if I have to heed to warnings and go with the same 1600x900 resolution or would the same laptop work with 1920x1080 resolution too.

Thank you

Lenovo ThinkPad T470: ThinkPad T470 Battery Replacement Leads to Horribly Slow Performance

Mon, 22 Mar 2021 08:26:46 -0700

I own a Lenovo ThinkPad T470 and ordered a replacement battery (Item code: IF245-023-1) found here.

Once I installed my battery into my laptop, letting it fully charge, the computer speed has slowed down immensely. I am pretty sure I’ve purchased the correct battery spec.

What can possibly be wrong/what can I do to fix this issue?

Could the battery itself be faulty?

ThinkPad T420: Power / Startup Issue?

Fri, 06 Mar 2026 08:46:20 -0700

Greetings all,

I have a Lenovo ThinkPad T-420, and it appears to be in good condition. (I found it in my friend's garage and he said I could have it!) But even with a "good" working battery?...or plugged in with a "good" working power adapter it won't power on. its as if there's no power to the device even though there IS a good battery and power supply(and I know the battery and power supply are good because I have ANOTHER T-420 that they came from!) )Its not a bad looking laptop, and I would like to use it, but if its not working I don't know what to do next. Can anyone shed some light on this issue for me? Or is there someplace I ca ship it to be repaired?

This has been happening for some time now: it started with "sometimes my laptop does not charges its battery and I hear a clicking noise" and now it simply does not charge and I can't figure out what is the problem.

I have opened the laptop to try and understand where the clicking noise is coming from, but couldn't find the origin.

Have anyone experienced something like this before?
