Laptop Battery Health: Tips to Prolong Your Battery's Lifespan

Laptop battery health is taken for granted. However, its original manufacture quality and ongoing useage are significant factors in extending your laptop’s longevity.

Modern laptops use lithium‑ion batteries. They are reliable and even though technology improves, they do wear down over time. The good news is that you can slow that ageing significantly. With the right settings, habits, and software tools, you can keep your laptop battery health strong for years. This guide explains practical steps any user can apply, whether you own a Dell, Lenovo, HP, ASUS, or another brand. If you need help fine‑tuning your setup, please get in touch.

Why Power Management Matters for Laptop Battery Health

Lithium‑ion batteries age fastest when held at a very high charge or exposed to unnecessary heat. Manufacturers like Dell openly recommend limiting maximum charge to around 80% to reduce wear, noting that custom settings such as <Start Charging> at about 60% charge and <Stop Charging> at about 80–90% help preserve long‑term capacity. Especially with low cost hardware where componentry is necessarily inexpensive, it makes sense to ease stress on this kind of battery.

General battery‑care discussions from wider user communities also support keeping charge levels between 40% and 80% for optimal laptop battery health.

Keeping your laptop plugged in at 100% all day may feel convenient, but it increases chemical stress inside the battery. Likewise, letting it regularly drain to near zero also accelerates degradation. Managing these extremes will improve laptop battery health.

Use Charge Limits to Improve Laptop Battery Health

Major manufacturers feature built‑in tools that let you control when charging starts and stops. This is not necessarily a laptop issue. For instance, current iterations of Android and iOS provide battery power management tools.

Cautionary warning

Even among large manufacturers which use better quality components, low price points mean laptop batteries can often be prone to premature failure. This is not a universal eventuality. However, premium hardware is more durable and less prone to failure. So, especially where lower cost hardware is concerned, using a strategy that reduces strain on a lithium-ion battery is desirable.

Leading manufacturers have different approaches. Some provide software, and usually BIOS will include power management features, which is probably the better way to handle power management.

ASUS

  • ASUS Armoury Crate or MyASUS offers “Battery Health Charging” modes such as Maximum Lifespan Mode, keeping charge around 60% or 80%.

Dell

  • Dell Power Manager or BIOS settings allow users to set custom ranges such as Start at 60% / Stop at 80%, aligning with Dell’s guidance to reduce “high‑state‑of‑charge dwell.”

HP

  • Some HP Business models include BIOS‑level “Maximize Battery Life” settings that prevent charging to 100%.

Lenovo ThinkPad / IdeaPad

  • Lenovo Vantage typically includes a “Battery Conservation Mode,” often limiting charging to around 55–60%.
Laptop Battery failure symptoms

Battery failure is usually a gradually developing situation and it is not always obvious that a battery is compromised. There are three main symptoms to look out for:

  • your battery life starts degrading, requiring increasing mains power input to maintain charge
  • the maximum battery charge capacity diminishes as cells fail
  • the battery swells, often causing warping of the laptop chassis

The last symptom is the most serious. By this point, the battery is already compromised and poses catastrophic risk to the laptop as motherboard and circuits are stressed. Beyond damage to the device, this kind of battery damage poses a fire risk.

These symptoms are equally relevant to mobile phones and tablets.

Everyday Habits That Support Laptop Battery Health

Improving laptop battery health goes beyond charge limits. Higher-end laptops, and even more recent Android iterations provide AI monitoring to gauge charging strategies. Common sense is a cheap fix, too. These small habits make a long-term difference:

  • Avoid constant 100% charging. High charge levels accelerate wear.
  • Avoid deep discharges. Letting the battery reach 0% shortens lifespan.
  • Keep your laptop cool. Heat is one of the biggest contributors to cell damage. Using your device in a well‑ventilated area helps maintain battery longevity.
  • Store your laptop at around 50% charge if not used for several days. This aligns with Dell’s own storage guidance.
  • Avoid cheap chargers. Under‑powered power bricks can cause inconsistent charging and more heat, reducing battery health.

These straightforward changes can noticeably slow wear and prolong functional lifespan.

Summary

Not all systems expose the same settings, and some users may need organisation‑wide configuration, BIOS adjustments, or compatibility checks. If you want the best configuration for your device—or your fleet—comstat.uk can help you:

  • Select ideal charge‑limit ranges.
  • Configure BIOS‑based battery settings.
  • Recommend manufacturer‑approved power tools.
  • Diagnose battery‑health concerns.
  • Apply policies across multiple business devices.

Proper configuration ensures your laptop battery health remains as strong as possible over the full lifecycle of your device.

How to manage a web site contact form

by | Jul 10, 2025

Contact forms - understand your risk

Website contact forms are a convenient way for visitors to get in touch with you. However, they introduce potentially catastrophic risks that you should be aware of.

Contact form field validation

Validating form fields helps reduce risk of malicious injection which could hijack or destroy your web site.

Browse this article to explore inherent contact form risks and how to manage them, especially if you are a “self-serve customer. If you do not rely on our optional support, there may be charges for support requests.

Click on the headers below to find out how to find out more about contact form issues. Click on images to view at full-sized resolution.

Malicious infiltration, abuse, and DNS

Web site forms are problematic. It should be easy to display a form that asks for a name, email address, phone number, and message. It is easy to make the form look attractive. However each field in a contact form is an open invitation for a hacker to destroy your web site or orchestrate a bulk email of thousands of emails that you end up bearing the cost of. Without concerted attention, it is a matter of time before a hacker finds a vulnerable contact form.

Contact form problems fall into two areas:

Malicious infiltration and abuse

Contact forms are a significant target for malicious activity. Hackers look for vulnerable contact forms to inject harmful code into your website. Statistically, small businesses are the most frequently exploited victims. Malicious infiltration causes catastrophic trouble like data breaches or site crashes. Common attacks include SQL injection (aka vector attack) or cross-site scripting (XSS). Additionally, spammers might flood your form with junk messages, making it hard to find genuine inquiries.

DNS Issues and Email Validation

When someone submits a contact form message at your web site, the information is often sent to an external email address. If there are issues with your Domain Name System (DNS) settings, these emails will probably be dropped without notice to anyone. Since contact form abuse is such a significant target for abuse, email gateway servers are especially sensitive to improperly validated email headers. This means your email server has to be correctly configured with your web site’s IP address using SPF, rDNS, DKIM, and DMARC.

Usually, resolving your DNS for contact form validation needs expert attention and may be beyond the scope of a web designer or in-house expertise. This does not mean web designers do not know their job. Intead, DNS is its own skillset, requires specialised knowledge,and also needs to take account of broader IT processes in your organization.

How to secure your contact form

Here are the three most important things you can do to secure your contact form:

Validate form fields

If you do not restrict the size and content of a form field, anyone can inject source code (an executable program), click <send> and your web server will execute the code which could mean web site destruction or hijacking your identity. Either eventuality is catastrophic and it is easier to do than reading this article.

Therefore, validate fields to limit the length of text. For instance,

  • <name> fields could be restricted to 20-30 characters
  • numerical composition of a phone number might have to comply with a special formatting, like aaaaa bbb ccc
  • email addresses might need to contain “@”, include a valid domain extension like “.co.uk”, and be limited to 40-50 characters
  • “message” field could be restricted to 150, 250, 350 characters

This is all “client-side” operation. All of these seriously curtail options for hackers. 

DNS

DNS is especially problematic. For instance, your email might be handled by your domain name registrar, or Microsoft 365, and your contact form has nothing to do with your organisation’s usual email server.

Usually, your domain name needs to be customised to include the location and characterisitcs of your contact form. This is “server-side”, and actually not even that because often these modifications might need scripting at a domain name registrar. This is what is called DNS, and it is one of the most difficult technologies to handle – even most web designers rely on upstream support for help with DNS. 

Regular testing

Test your contact forms regularly. Keeping spam out of email Inboxes is a moving battlefield. The web server itself is not the problem – when instructed, it acts, and in some ways that is part of the problem – it does not know how to discriminate between good and bad content without form validation.

Hackers are creative, and organizations like Google, Microsoft, and Yahoo spend billions to keep up with evolving threats. In so doing, new security may render the source code you rely on for your contact form irrelevant, and the contact form programmer might not even know their source code is now outdated. Large organisation pay full time salaries just for someone to manage a contact form – daily. Moving to text-based chat bots is not designed to annoy customers – it is an attempt to avoid contact forms in the first place.

Summary and alternatives

Contact forms require constant owner-maintenance and are subject to ever-changing security threats. Also, because your form is programmed on “client-side” (e.g. in WordPress), owners assume responsibility for secure operation of their contact form.

Even if you undertake the overheads of managing your contact form, your contact form should only be one way for customers to contact you. For example, alternate channels like those below move direct risk away from your web server:

  • Social media contact options like WhatsApp for Business, Facebook, Insta, etc.
  • Microsoft 365 Forms or Google Forms, which can be embedded on your web site
